Answer:
x=5
Step-by-step explanation:
F(x)=-3x+21,
f(x)=6 = -3x+21
6 = -3x+21
Subtract 21 from each side
6-21 = -3x+21-21
-15 = -3x
Divide each side by -3
-15/-3 = -3x/-3
5 = x
Answer: 9.6
Step-by-step explanation: I did a proportion, 2.4/1.5=?/6 so 6/1.5= 4 so 2.4*4= 9.6
So a person can walk 9.6 miles in 6 hours.
Hope this helps!
Answer:
D. 2x + 7
Step-by-step explanation:
Use the point given, (-3, 1), and put it into the point-slope formula.
y - 1 = m(x+3)
The m, or the slope, is still blank. When you want a line parallel to a certain slope, the slope remains the same. Therefore, you plug in 2 for m:
y - 1 = 2(x+3)
y - 1 = 2x + 6
y = 2x + 7
