The Answer:
The axis of symmetry should be x=2
Step-by-step explanation:
The question clearly states x+2 meaning it shouldn't be - 2
Not entirely sure
2 inches of the model - 25 inches of the actual car
15 inches of the model - x inches of the actual car
![\frac{2}{25}=\frac{15}{x} \\ 2x=25 \times 15 \\ 2x=375 \\ x=187.5](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B25%7D%3D%5Cfrac%7B15%7D%7Bx%7D%20%5C%5C%0A2x%3D25%20%5Ctimes%2015%20%5C%5C%0A2x%3D375%20%5C%5C%0Ax%3D187.5)
The actual car is 187.5 inches long.
Answer:

Step-by-step explanation:
Using the rule of radicals
×
=
, then
![\sqrt{72}](https://tex.z-dn.net/?f=%5Csqrt%7B72%7D)
= ![\sqrt{36(2)}](https://tex.z-dn.net/?f=%5Csqrt%7B36%282%29%7D)
=
× ![\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D)
= 6![\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D)
is in simplest form, and cannot be simplified further
Answer:
c. 10=4(3)+b; b=-2
Step-by-step explanation:
When given a single point (x1, y1)
The Equation of a line formula is given as:
y - y1 = m(x - x1)
From the question
m=4
the point is (3,10),
Hence, Equation of the line is
y - 10 = 4(x - 3)
y - 10 = 4x - 12
y = 4x - 12 + 10
y = 4x - 2
Hence, the correct substitution (y=mx+b)
10 = 4(3) + b
b = -2
Option C is the correct option

Answer:
43°
Step-by-step explanation:
Following the instructions is generally useful.
5x +9 = 30 -3x +27 +2x
6x = 48 . . . . add x-9
x = 8 . . . . . . .divide by 6
27 +2x = 27 +2(8) = 43 . . . . substitute into the expression for angle DFE
angle DFE = 43°
