-27 - (-3) = -27 + 3 = - 24
560 - 2(25 + 11) = 560 - 2(36) = 560 - 72 = 488
8y - x^2....x = -5, y = 4
8(4) - (-5)^2 =
32 + 5^2 =
32 + 25 =
57
Answer:
There is no x-intercept, only a y-intercept, which would be 1
(17.5)(x)=125
Divide each side by 17.5 leaving the equation as x=7.14
Answer:
D. N(a) = (a + 20)/3
Step-by-step explanation:
A(n) = 3n - 20
A is a function of n. The inverse will be: N is a function of a.
Change A(n) to y and n to x.
y = 3x - 20
Switch x and y.
x = 3y - 20
Solve for y.
x + 20 = 3y
3y = x + 20
y = (x + 20)/3
Now switch y to N(a) and x to a.
Answer: N(a) = (a + 20)/3
