Answer:
(-5, 2) and (2, 6)
Step-by-step explanation:
Use the substitution method. We know that y = 3x and y = x^2 - 10, so we can set them equal to one another.
3x = x^2 - 10
x^2 - 3x - 10 = 0
Use the quadratic equation to solve for x.
x = - 5, 2
Now solve for y using these two values of x by substituting it back into the equations.
y = - 15, 6
In coordinate form, (-5, 2) and (2, 6)
Answer:
f(x) = 15
Step-by-step explanation:
"If f(x)= 5x + 40, what is f(x) when x = -5?"
Substitute x for -5:
f(x) = 5x + 40
f(x) = 5(-5) + 40
f(x) = -25 + 40
f(x) = 15

Answer:
B. 56
Step-by-step explanation:
The exterior angle 72° is half the difference of the intercepted arcs, 200° and x:
72° = (200° -x)/2
144° = 200° -x
x = 200° -144°
x = 56°
35 = 7 * 5
(7n + 3)(5n + 1)
= 35n^2 + 7n + 15n + 3
= 35n^2 + 22n + 3
so answer is
(7n + 3)(5n + 1)
