Simplifying
4+-7=8t+3

Reorder the Terms 
-7+4=8t+3

Reorder The terms again
-7+4t=3+8t

Solving for the variable T

Move all terms containing t to the left, and all other terms to the right

Add -8t to each side of the equation

-7+4t+-8t=3+8t+-8t

Combine like terms

4t+-8t=-4t

7+-4t=3+8t+-8t

Combine like terms 

8t+-8t=0

-7+-4t=3+0
-7+-4t=3

Add 7 to each side of the equation

-7+7+-4t=3+7

Combine like terms

0+-4t=3+7
-4t=3+7

Combine like terms 3+7=10

-4t+10

Divide each side by 4
t= -2.5

Simplifying
t= -25

Okay, so we have
4t - 7 = 8t + 3
We Need to Simplify.
Add 7 to both sides to begin.
4t = 8t + 3 + 7
Now, Combine 7 + 3
4t = 8t + 10
Combine the ts
-4t = 10
Divide.
-4t/-4 = 1t = t
t = 10/-4
10/-4 = -2 and 2/4
-2 and 2/4 = -2.5
t = -2.5

1. The equation y=x^2-9x+20 models the roller coasters path over time. The variable y represents height (in feet) above or below
azamat

Answer:

1) the factored form is  y= ( x-5 ) ( x+4 )

2) the vertex is (4.5, -0.25)

3) the y intercept is when x equals 0 so it is at (0,20)

4) it opens upward and the vertex is (4.5, -0.25) the x intercepts are (4,0) and (5,0) and the y intercept is  (0,20)

5)

a. it dips  between 4 seconds and 5 seconds so the x intercepts are (4,0) and (5,0)

b. it is taken at the vertex aka the lowest point so the height is -0.25

Find the value of a and YZ if Y is between X and Z. XY = 7a, YZ = 5a, XZ = 6a + 24 = YZ =​
Aleksandr-060686 [28]
  • x-y-z

\\ \sf\longmapsto XY+YZ=XZ

\\ \sf\longmapsto 7a+5a=6a+24

\\ \sf\longmapsto 12a=6a+24

\\ \sf\longmapsto 12a-6a=24

\\ \sf\longmapsto 6a=24

\\ \sf\longmapsto a=\dfrac{24}{6}

\\ \sf\longmapsto a=5

  • YZ=5a=5(5)=25
