a 
7
because 4a + 7 - 7 35 - 7
equals 4a 28
and 4a/4 28/4
equals a 7
Answer:
4
Step-by-step explanation:
hope the diagram helps haha
2 (l + w) = 36
l + w = 18
2x + 7x = 18
9x = 18
x = 2
the length of the sides
l = 2x
l = 2(2)
l = 4
w = 7x
w = 7(2)
w = 14
Answer: The answer is B). 1/4
Step-by-step explanation:
Answer:
f(x) = 4x + 10
Step-by-step explanation:
The given information is in the form f(x) = y.
f(0) = 10 means if x is 0, y is 10. This is the point (0,10)
Likewise, f(6) = 34
means when x is 6, y is 34. That is the point (6,34).
Slope is y-y / x-x
34-10 / 6-0
is 24/6.
The slope is 4.
The y-intercept is where x is 0, that is 10.
y=mx+b is slope-intercept form. Fill in the slope, 4 for m and the y-intercept, 10, for b.
y = 4x + 10
but they also asked to call it f, so for function notation, use f(x) instead of y.
f(x) = 4x + 10
