Answer:
12.
Step-by-step explanation:
According to Pythagorean's Theorem, x^2+25=169. If you subtract 25 from both sides, you might get x^2=144. You then square both sides and get that x=12.
Answer:
256
Step-by-step explanation:
4×4=16
16×4=64
64×4=256
Let A(4,12) and B(6,18)
RATE OF CHANGE = m = (y₂ - y₁) / (x₂ - x₁) = (18-12)/ (6-4)
m= 6/2 or m = 3
A (-1,2)
using substitution:
substitute-2x for y in the second function
7x - 8(-2x) = -23
solve for x
7x + 16x = -23
23x = -23
x = -1
plug x = -1 into a function to find y, in this case ill plug it into the first
y = -2(-1)
y = 2
since x = -1 and y = 2
the answer is A (-1,2)
