Answer:
X=7
Step-by-step explanation:
we already know the slope is -2, so y=-2x+m
since the line goes through point (5,1)
1=(-2)x5+m
1=m-10
m=11
the equation should be y=-2x+11
-3=2x+11
-14=2x
x=7
determine the size of V
Answer:
Size of V = 95°
Step-by-step explanation:
The total sum of angles in a triangle is 180°
You can find Angles T and V.
2x+3x+5 = 180°-25°
5x+5 = 155°
5x = 155°-5
= 150°
x = 150°÷5
= 30°
Angle V = 3×30°+5
= 95°

what is 4x + 9 = 68 in the clearest number possible
Answer:
x = 59/4
Step-by-step explanation:
4x + 9 = 68
Subtract 9 from both sides.
4x + 9 - 9 = 68 - 9
4x = 59
Divide both sides by 4.
4x/4 = 59/4
x = 59/4
Answer:
X=0.75
Step-by-step explanation:
Step 1:
68-9=59
Step 2:
59 divided by 4= 14.75
Step 3:
0.75=3/4
14 3/4=14.75
Solution:
X=0.75
Another way is 59/4=14.75

Total yards Jason has = +30 -40 +10
= +40 -40
= 0
Answer: 0
Step-by-step explanation:
30 - 40 + 10

The sum of 2 numbers is 50. The sum of 1/4 of the first number and 2/3 of the second number is 25.What are the numbers?
HELLLLLPPPPPP
Answer:
First number: 20
Second number: 30
Step-by-step explanation:
First#: x
Second#: y
Constraints:
x + y = 50
1/4x + 2/3y = 25
Isolate variable y:
x + y = 50
-1/4 (x + y = 50 )
-1/4x - 1/4y = -12.5
Add equations the two equations to eliminate x:
-1/4x - 1/4y = -12.5
1/4x + 2/3y = 25
_________________
5/12y = 12.5
5y = 150
y = 30
Substitution to find x:
x + y = 50
x + 30 = 50
x = 20
Solve the absolute value equation. 4|4x - 3| - 8 = -4
Answer:
x = [tex]1,\frac{1}{2}[/tex]
Step-by-step explanation:
[tex]4|4x-3|-8=-4\\[/tex]
Add 8 to both sides;
4|4x - 3| = 4 4|4x - 3| = -4
Divide both sides by 4;
4x - 3 = 1 4x - 3 = -1
Add 3 to both sides;
4x = 4 4x = 2
Divide both sides by 4;
x = 1 x = [tex]\frac{1}{2}[/tex]

Find the arc length of the curve on the given interval. Parametric Equations Interval x = 6t + 5, y = 7 − 5t −1 ≤ t ≤ 3
Answer:
31.241
Step-by-step explanation:
x = 6t + 5, y = 7 − 5t −1 ≤ t ≤ 3
dx/dt = 6
dy/dt = -5
The arc length of the curve can be calculated below as

is (11,9), (11,5), (9,3) a function
Answer:
[tex]\huge{ \boxed{ \sf{No}}}[/tex]
✑ Question :
Is ( 11 , 9 ) , ( 11 , 5 ) , ( 9 , 3 ) a function ?No , it's not a function.
✎ Reason :
This is not a function because one element 11 of set A is associated to elements 9 and 5 of set B.
♨ Explore about function :
↪ Function is a special type of relation. It is the refinement of relation. In a relation from A to B , every element of set A should have only one ( distinct ) image in B to be a function. In other words , if no two different ordered pairs have the same first component , then it is a function.

Answer:
-3x+1y=-1
or
3x-1y=1
or
by multiplying with 1/3 the first equation we get
-1x+1/3y=-1/3
or from second equation
1x-1/3y=1/3
Step-by-step explanation:
y-y1=m(x-x1)
y1=-7
x1=-2
m=3
so
y-(-7)=3(x-(-2))
y+7=3(x+2)
y+7=3x+6
-3x+y=6-7
-3x+ 1y= -1
Can someone explain step by step
Answer:
Check below for step-by-step guide.
Step-by-step explanation:
a) Recall the formula for area is length times width. You are given both of those values. Width= (5x+2) and length = (4x-1). All you have to do is multiply them. You will get a quadratic!
b) This is just basically a lot of plugging in to the equation: Volume= length x width x height. So let's look at what we have!
It says our volume is 20x^3 + 63x^2+ 7x-6
It says our width is : (5x+2)
It says out length is (4x-1).
So the volume = l x w x h , we just plug in those numbers I listed above :
20x^3 + 63x^2+ 7x-6= (4x-1) (5x+2) (height)
Now remember you already multiplied length times width in problem (a). You can use that expanded quadratic on the right side. Then subtract values and isolate height!
You asked for an explanation of what to do step by step, so if you actually need help solving it, comment please! :)
