What is the solution to the system of equation? Write you answer as a coordinate point.
Answer:
Step-by-step explanation:
Ok, so we have the equations:
7x-2y=-13
and
2y-5x=11
So first things first, we can cancel out 2y from both equations because they are common factors.
So we are left with the equations:
7x=-13
and
5x=11
So we add the two common factors and get:
12x=-24
And now we divide on both sides and get:
x=-2

Help i need to past this test to get my permit
Answer:
See below for answers
Step-by-step explanation:
1st Problem:
Because the figure is a triangle, it's interior angles will add up to 180 always. Since it's a right triangle, we know one of the angles is 90, but we'll need to set up an equation to solve for x.
90+(2x-2)+(x+5)=180
2x-2+x+5=90
3x+3=90
3x=87
x=29
Therefore, B) 29, is the correct answer
2nd Problem:
Given side lengths of a, b, and c, if a+b<c, then it's a triangle. Since 8+8 is not less than 16, the sides do not make a triangle. The hypotenuse, c, must always be the longest length.
Therefore, A) Not a triangle, is the correct answer
3rd Problem:
To find angle x, we need the last interior angle of the triangle. Since the interior angles of a triangle add up to 180, we once again set up an equation to find the missing interior angle:
21+34+y=180
55+y=180
y=125
Since the missing interior angle is 125 degrees, it is supplementary to angle x, where supplementary angles add up to 180 degrees as well. So we would subtract 125 from 180 to get x. 180-125=55, so angle x is 55 degrees. Therefore, C) 55, is the correct answer.
4th Problem:
Again, use the Interior Angle Theorem to get x:
58+47+x=180
105+x=180
x=75
Therefore, A) 75, is the correct answer
5th Problem:
3,4,5 is a Pythagorean Triple, so it is a right triangle as 3^2+4^2=5^2. It is also scalene because none of the sides are equal to each other.
Therefore, B) Yes, scalene, is the correct answer

Two integers that have an absolute value of 10 are...and...
I will give a brainlist
Answer:
10 and -10
Step-by-step explanation:
Absolute value is the distance of a number from 0. Absolute value must be positive because you can not a have a negative distance from 0. The two numbers that have a distance of 10 from 0 on the number line are 10 and -10.
Answer:
The symbol for absolute value is two vertical lines. Since opposites are the same distance from the origin, they have the same absolute value. For example, the absolute value of "negative 10" is ten, and the absolute value of "positive 10" is also 10.

Help plz:))) I’ll mark u brainliest
Answer:
25x = 75 (Because they are alternate interior angles)
=> x = 75/25
=> x = 3
So, x = 3
Because 25x is equal to 75, the two lines (u and v) are parallel
x = 3
180-75 = 105
180-105 = 75
75/25 = 3
Consider a triangle with two sides that
measure 7 cm and 11 cm forming an angle
that measures 100°.
Find the length of the third side to the nearest centimeter
A) 12 cm
B) 13 cm
C) 14 cm
D) 15 cm
9514 1404 393
Answer:
C) 14 cm
Step-by-step explanation:
A triangle solver can quickly show you the third side is 14 cm.
__
The law of cosines can be used for this purpose. If the given sides are 'a' and 'b', and the third side is 'c', then that law tells you ...
c² = a² +b² -2ab·cos(C)
c² = 7² +11² -2·7·11·cos(100°) ≈ 196.74
c ≈ √196.74 ≈ 14.03
The length of the third side is about 14 cm.
Write the equation of a line in slope intercept form giving the following:
A: m=2 (0,-7)
B: (3,-4) (-2,1)
C: f(2)=6 f(0)=5
Answer:
Equation of a straight line is given as y = mx+c
m = slope or gradient or dy/dx or y2 - y1/ x2 - x1
c = intercept
y = 2x - 7
y = -x + 1
y = 2x - 10
Step-by-step explanation:
Using y = mx+c
A. m=2 y=-7 x=0
-7= 2*0 + c
-7=c
y = 2*x - 7
y = 2x - 7
B. x1=3 x2=-2 y1=-4 y2=1
m = y2 - y1/ x2 - x1
m = 1+4 / -2-3
m = 5/-5 which is equal to -1
using any value for y and x, let's use x1 and y1
-2 = -1*3 + c
-2 = -3 + c
1 = c
y = -1*x + 1
y = -x + 1
C. x1=6 x2= 5 y1= 2 y2=0
m = y2 - y1/ x2 - x1
m = 0-2 / 5-6
m = -2/-1 which is equal to 2
using any value for y and x, let's use x1and y1
2 = 2*6 + c
2 = 12 + c
-10 = c
y = 2*x -10
y = 2x - 10

In the diagram above, ∠1=135° . Find the measure of ∠2.
Answer:
Angle 2 = 45 degrees
Step-by-step explanation:
Angle 1 = Angle D because they are alternate interior angles.
Angle 3 = Angle A because they are alternate exterior angles.
Angle 1 = 135 degrees
Therefore, Angle D = 135 degrees
180 - Angle D = Angle 2
Angle 2 = 180 - 135
Angle 2 = 45 degrees

1. Cindy did an experiment. She started out with 700 bacteria cells. She found that the growth rate of the
bacteria cells was 4.3%. Create an equation for the situation that would work for any time, x. Type your
equation into Desmos to make a graph that represents her experiment.
given and, write the new function rule (equation) for function and describe (using words) the two transformations that occur between function and function.
i already got the equation for the first part: y=700(1.043^x) but i don’t understand the second part.
Answer:
See the screenshot! :)
Step-by-step explanation:
we have a exponential function of the form
y=a([tex]b^x[/tex])
where
y ---> is the population of bacteria
x ---> the number of hours
a is the initial value or y-intercept
b is the base of the exponential function
r is the rate of change
b=(1+r)
we have
a=700 bacteria
r=5%=5/100=0.05
so
b=1+0.05=1.05
substitute
y=700([tex]1.05^x[/tex])
For x=20 hours
substitute in the equation and solve for y
y=700(1.05)^20= 1,857 bacteria
Hope this helped! :)

A medication is administered with a dose of 10 milligrams. After 3 hours there are 6.5 milligrams in the patient's system. What is the half life of the medication, in hours? Round to one decimal place.
Answer:
4.8 hours
Step-by-step explanation:
The formula for half life is given as:
t½ = t × In(2)/In(No/Nt)
Where
t½ = Half life
t = time in hours = 4
No = Initial amount = 10mg
Nt = Final amount after 3 hours = 6.5 mg
t½ = 3 × In(2) /In(10/6.5)
t½ = 4.8271216522281 hours
Approximately = 4.8 hours
The half-life of the medication, in hours, is 4.8 hours.
Given that,
Medication is administered with a dose of 10 milligrams. After 3 hours there are 6.5 milligrams in the patient's system.Based on the above information, the calculation is as follows:
The following formula should be used:
[tex]= t \times ln(2)\div ln(No\div Nt)[/tex]
Here
t denotes the time in hours i.e. 4
No means the Initial amount i.e. 10mg
Nt means Final amount after 3 hours i.e. 6.5 mg
So,
[tex]= 3 \times ln(2) \div ln(10\div 6.5)[/tex]
= 4.82
= 4.8 hours
Therefore we can conclude that the half-life of the medication, in hours, is 4.8 hours.

Rayna paid a $200 fee to join a health club and then a $50 fee per month to use the club. The total amount of money (t) paid can be represented by the equation t = 200 + 50 m , where m represents the number of months of club use. Nora paid a $100 fee to join another health club and then a $75 fee per month to use the club, which can be represented by the equation t = 100 + 75 m . The graph below shows the fees paid by Rayna and Nora. In what month will both girls have paid an equal amount of money to their health clubs?
Answer:
the fourth month
Step-by-step explanation:
200 + 50m = 100 + 75m
subtract 100 on both sides
100 + 50m = 75m
subtract 50m on both sides
100 = 25m
divide by 25 on both sides
m = 4

Step-by-step explanation:
Forst thing to do in this is to write it out, it makes more sense of the problem.

Find f (77)
f(p)=7/11p-10:
A: f(77)=59
B: f(77)=39
C: f(77)=49
D: f(77)=67
Answer:
I don't know, the way it is typed confuses me. Is it 7/11 TIMES p-10 or is p-10 with the 11 as the denominator? but I do hope this helps:
Step-by-step explanation:
So first I subtracted 7/11 from each side:
f(p)-7/11=(7/11-7/11)p-10
Now we are left with f(4/11p)=p-10
Now to get the variable "p" on one side, I subtracted 4/11p from both sides:
f(4/11p-4/11p)=(p-4/11p)-10
Now we are left with f=7/11p-10
Now we want the "p" to be 1p so we multiply each side by the reciprocal of 7/11:
f(11/7)=(7/11*11/7)p-10
Now we have 1 4/7f=p-10
Now we subtract 4/7 from each side and get:
f=p-9 3/7
And that's as far as I could simplify it, sorry if it's wrong... lol
The required value of f (77) is 39 for the given equation. The correct answer would be an option (B).
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
The equation is given in the question, as follows:
f (p) = (7/11) p - 10
We have to determine the value of f (77) for the given equation.
As per the question, we have
f (p) = (7/11) p - 10
Substitute the value of p = 77 in the above equation,
f (77) = (7/11)(77) - 10
f (77) = 7 x 7 - 10
f (77) = 49 - 10
Apply the subtraction operation, and we get
f (77) = 39
Thus, the value of f (77) is 39.
