A race

sashaice [31]

Answer: 187.7 mph

Step-by-step explanation:

v = 125 mph

t = 1.2 min

v2 = ?

t2 = 0.8 min

We can use the rule of 3 here. It's the inverse rule of 3 because as time decreases, speed increases.

$\frac{125mph}{x} =\frac{1.2min}{0.8min}$

$x = \frac{(125)(1.2)}{0.8}$

$x=187.5mph$

7x - 6 =85

add 6 to each side

7x =91

divide each side by 7

x = 91 /7 = 13

If f(x) = 3x2 – 12x + 4, find f(–2).<br> A) -40 <br> B) -20 <br> C) 20 <br> D) 40

Digiron [165]

Answer:

The answer is D

Step-by-step explanation:

f(x) = 3x² - 12x + 4

f(-2) = 3(-2)² - 12(-2) + 4

= 12 + 24 + 4

= 40

Given f(x)=3x-1 and g(x)=2-3, for which value of g(x)=f(2)?

djverab [1.8K]

We have, by function notation, that

f(2)=3(2)=5

now we have
2x-3=5
2x=8
x=4

So the answer to this is 4
Hope this helped :)
Have a great day
