Help pls! What is the solution to the following system of equations?
Answer:
(2,-1)
Step-by-step explanation:
We know that,
Whenever a point lies on the graph of an equation, the coordinate pair of the point will be a solution to the equation.
As in this case,
(2,-1) lies on the lines of both Equation 1 and Equation 2. Hence, their common solution is (2,-1).

Step-by-step explanation:
Multiply first:
[tex]6.75*3=20.25[/tex]
Now add (when adding a negative and a positive, subtract the two numbers. Then keep the symbol of the greatest number for the result. Since 20.25 is greater, the result will be positive):

Step 2: 3x4=12 You need 12 cups of flour.
helppp me find x plz
Answer:
x = 5
Step-by-step explanation:
The ≅ sign means that both triangles are congruent, also meaning they're exactly the same. So with this in mind, the equations naturally equal each other:
3x + 3 = 5x - 7
Subtract 5x from both sides
-2x + 3 = -7
Subtract -3 from both sides
-2x = -10
divide by -2 to both sides
x = 5

Your late grandfather left you and your cousin his property in his will. Below is a map of the
property with a road that cuts through the property
North Property Border
Road
South Property Border
1. On the diagram, two angles (<1 und 2) formed by the road, and the borders are congruent.
What is the relationship
between the north and south property borders of your prandfather's
land?
Explain how you know
2. How are <3 and <1 related to each other
Explain how you know
Answer:
1. The North and South property border lines are parallel
2. ∠3 and ∠1 are supplementary angles
Step-by-step explanation:
The given parameters are;
The North and South Property Boarders are given
The road intersects (transverses) the North and South Property Boarders
∠1 and ∠2 in the given diagram are congruent
1. Given that ∠1 ≅ ∠2, and from the diagram, ∠1 and ∠2 are alternate interior angles, we have that alternate interior formed by the transversal of two parallel lines are congruent
Therefore, the North and South property border lines are parallel
2. ∠3 and ∠1 are same side interior angles
When two parallel lines have a common transversal passing through them, then the same side interior angles are supplementary
Therefore, ∠3 and ∠1 are supplementary (angles whose sum is 180°)
The proof is that ∠3 and ∠2 are supplementary, because they are the angles on a straight line
∠2 ≅ ∠1 which is given
∴ ∠2 = ∠1 by definition of congruency
∠3 and ∠1 are therefore, supplementary, by substitution property of equality
Please Help!!! And please dont answer with anything random I really need help!!!
okay, let's see if I can do this without my calculator
using the Bernoulli Trial equation (I think that's what it's called)
nCr x (p)^r x (q)^n-r
now 5C4 is 5 (Thanks Pascal's triangle)
p is 1/3
q is 2/3
r is 4
n is 5
(1/3)^4 is 1/81
(2/3)^5-4 is just 2/3
5 x 1/81 x 2/3 = 5 x 2/243 = 10/243

60% of the 50 students in Jessie’s gym class are 12 years old. How many students in Jessie’s class are 12 years old?
A tape diagram. There are 60 students out of 100 that are 12 years old. There are question mark students out of 50 that are 12 years old.
What steps should you use to find 60% of 50? Check all that apply.
100 ÷ 20 = 50
100 ÷ 2 = 50
60 ÷ 2 = the number of students who are 12 years old.
60 ÷ 20 = 3 students
60 ÷ 2 = 30 students
30 of the 50 students are 12 years old.

Juan is on the roof of that building. He isn't going to jump. He is spying on his ex girlfriend and her new boyfriend the angle of depression is 24. He hates her she just moved on like he didn't matter. He notices them sitting on the bench from the foot of the building. How far is the bench from the foot of the building?
Answer:
27m approx based on 12m height of building
Step-by-step explanation:
Note since the height of the building is not given, we will assume a height of 12m
Step one:
Angle of depression =24°
Let the distance of the bench from the foot of the building be x
Applying SOH CAH TOA
opposite is to the angle of depression is the height which is assumed to be 12m
The distance of the bench from the foot of the building is the adjacent
Tan 24=Opp/Adj
Tan24=12/x
x=12/Tan24
x=12/0.445
x=26.9
27m approx.
We assumed a height of 12m, you can as well use the actual height that you have and plug into the solution. Meanwhile a height of 12m gives 27m approximately

[tex]f(x) = x + \sqrt{x + 1 \frac{x} - {1} [/tex]
Answer:
A
Step-by-step explanation:
Given
f(x) = x + [tex]\frac{\sqrt{x+1} }{x-1}[/tex]
To evaluate f(3), substitute x = 3 into f(x) , that is
f(3) = 3 + [tex]\frac{\sqrt{3+1} }{3-1}[/tex]
= 3 + [tex]\frac{\sqrt{4} }{2}[/tex]
= 3 + [tex]\frac{2}{2}[/tex]

factor 4x^2-9x-9 and show work.
please explain the steps taken
Answer:
22x2 - 9x) - 9
Trying to factor by splitting the middle term
Factoring 4x2-9x-9
The first term is, 4x2 its coefficient is 4 .
The middle term is, -9x its coefficient is -9 .
The last term, "the constant", is -9
Step-1 : Multiply the coefficient of the first term by the constant 4 • -9 = -36
Step-2 : Find two factors of -36 whose sum equals the coefficient of the middle term, which is -9 .
-36 + 1 = -35
-18 + 2 = -16
-12 + 3 = -9
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -12 and 3
4x2 - 12x + 3x - 9
Step-4 : Add up the first 2 terms, pulling out like factors :
4x • (x-3)
Add up the last 2 terms, pulling out common factors :
3 • (x-3)
Step-5 : Add up the four terms of step 4 :
(4x+3) • (x-3)

11b+6 >/=14b+3
please help
Answer:
Solving the inequality [tex]11b+6 >=14b+3[/tex] we get b <= 1
Step-by-step explanation:
We need to solve the inequality [tex]11b+6 >=14b+3[/tex]
solving the inequality:
[tex]11b+6 >=14b+3[/tex]
Subtracting 6 on both sides
[tex]11b+6-6 >=14b+3-6\\11b >= 14b-3[/tex]
subtracting 14 b on both sides
[tex]11b-14b >= 14b-3-14b\\-3b >= -3[/tex]
Divide both sides by -3 and the inequality will be changed to less than equal i.e <=
[tex]\frac{-3b}{-3}<=\frac{-3}{-3}\\b<=1[/tex]
So, solving the inequality [tex]11b+6 >=14b+3[/tex] we get b <= 1
48 oranges 1 in every 6 oranges is rotten. How many rotten
oranges are there
Answer:
8
Step-by-step explanation:
Because 48 divided by 6 is 8
There are 8 rotten oranges in 48 oranges.
What is a ratio?The quantitative relation between two amounts that shows the number of times one value is contained within the other.
We can the number of rotten oranges below:It is given that the total number of oranges is 48.
It is also given that one in every six oranges is rotten. This means that the ratio of rotten oranges to total oranges = 1/6
We can find the total number of rotten oranges in 48 oranges as shown below:
48 * 1/6
= 8 oranges.
There are 8 rotten oranges in 48 oranges.
Therefore, we have determined that there are 8 rotten oranges in 48 oranges.
