Answer:
Step-by-step explanation:
three times the sum of a number and 4...
3(n + 4) would be ur expression
<span>three functions are
f(x) = 3(x + 4)^2 + 1
g(x) = 2x^2 - 16x + 15
h(x) = a(x - 1) - 3
Axis of symmetry for f(x) is x=-4 For g(x)
by taking the derivative
g'(x) = 4x - 16
= 4(x - 4)
Axis of symmetry for g(x) is x=4
Axis of symmetry for h(x) is x=1
hope it helps

Answer:
- B.) The 1,609 meters and the 3,218 meters in Step 1 should be switched.
Step-by-step explanation:
<u>Step 1 is incorrect. It should be:</u>
- 3218 meters x 1 mile / 1609 meters = 2 miles
Correct answer option is B
Answer:
7x = y + 37
Step-by-step explanation:
y = 7x - 9
Differentiating y with respect to x, we have as follows:
dy/dx = m = 7 ( where m is the slope)
Using the formula y - y1 = m(x - x1) to obtain the equation of line passing through point (4.-9)
y + 9 = 7(x - 4)
y + 9 = 7x - 28
∴ 7x = y + 37
