Answer:
D.) x = 7
Step-by-step explanation:
4x - 9x + 3 = -32
The first thing we do is combine like terms which means to add or subtract or multiply or divide any numbers that are known. Here in this equation we have 4x and - 9x
4x - 9x + 3 = -32
- 5x + 3 = - 32
Now what we do is subtract the common numeral from the side where the x value is.
- 5x + 3 = - 32
- 3. - 3
- 5x = - 35
Lastly, we divide here we take the value next to x and divide both numbers, here we will divide by - 5.
- 5x = - 35
- 5x / - 5 = x
- 35 / - 5 = 7
Now we take are two solutions and create are final solution.
x = 7

CommentThe two triangles (ABC and ADE) can be shown to be similar (which I'll do below). Their corresponding parts are also similar.
Step OneProve Similarity.
A is common to both triangles Construction
<ABC = <ADE Given as right angles.
By the AA Theorem both triangles are similar.
Step TwoFind x
AD is to AB as DE is to x
AD = 3 + 4 = 7
AB = 3
DE = 6
7 / 3 = 6/x Cross multiply
7x = 3 * 6
7x = 18 Divide by 7
x = 18/7
x = 2.571 <<<<<

Answer:
Axis of Symmetry:
x=2
Vertex:
(2,11)
Step-by-step explanation:
Finding the derivative:
f'(x)=-10x+20
Setting the slope equal to zero:
-10x+20=0 x-2=0 x=2
Finding vertex:
f(2)=-5*(2)^2+20*2-9
=-20+40-9=20-9=11
(2,11)
12 inches equals (or :1) foot; the ratio of inches to feet is 12 inches to one foot 24 inches; the ratio of feet to inches is 2:24. 6 feet equals 2 yards; the ratio of feet to yards is 6:3. 1 yard equals 3 feet; the ratio of yards to feet is 1:3
