f(16) =16
f(x) is the same thing as y so you can solve it the same way as any other equation. the only difference is when it has a number in the parentheses. if there is a number in the parentheses you will replace all of the x’s in the equation with that number. for example:
original problem problem with f(3)
f(x)=2x*-3x-7 f(3)= 2(3*)-3(3)-7

Leon drove from his house in Cincinnati to his sister’s house in Cleveland, a distance of 252 miles. It took him 4.5 hours. For the first half-hour, he had heavy traffic, and the rest of the time his speed was five miles per hour less than twice his speed in heavy traffic. What was his speed in heavy traffic?
Answers
Answer:
Speed in heavy traffic is 32 miles per hour
Step-by-step explanation:
Total distance = 252miles
Total time = 4.5hours = 4 hours + 30minutes
Let the speed in heavy traffic = x
distance = time * speed
First half hour
D1 = 0.5*x
The speed after the traffic = 2x - 5
D2= 4* (2x - 5)
Total distance = D1 + D2
[tex]\frac{x}{2}[/tex] + 8x - 20 = 252
[tex]\frac{17x}{2}[/tex] = 272
x = [tex]\frac{272}{17}*2[/tex]
x = 32 miles per hour

What is an equation in slope-intercept form of the line that passes through (6, 10) and is parallel to the graph of y=1/3x−1?
Here are the answer choices:
A: y−10=1/3(x−6)
B: y=1/3x+8
C: y−10=−3(x−6)
D: y=−3x+28
Answers
Answer:
B
Step-by-step explanation:
sope intercept form: (y=mx+b)
m = slope
m = 1/3 (slope of parallel lines are the same)
10 = 1/3(6)+b
10 = 2+b
b = 8
write with slope and b
y = 1/3x+8
The answer is B
