You will have to divide 140 by 8 and it will give u P you already know R equals 8
The vertex form: y = a(x - h)² + k
y = ax² + bx + c then h = -b/2a and k = f(h).
y = x² - 12x + 8
a = 1; b = -12; c = 8
h = -(-12)/(2·1) = 12/2 = 6
k = f(6) = 6² - 12·6 + 8 = 36 - 72 + 8 = -28
Answer: y = (x - 6)² - 28.
The answer is x = 3, as we know that the measure of vertical angles are equal. This means that 2x = x + 3, so x = 3.<span />
Yes.
a test for a function is the vertical line test, so think about drawing a vertical line on top of this picture. if at any point the line is touching the graph more than once, it is not a function. this graph passes the vertical line test
Equilatral
equi-equal
lateral-side
sides have to be equal
therefor
4n=2n+10=7n-15
minus 2n from everybody
2n=10=5n-15
2n=10
divide 2
n=5
see if that works
10=5n-15
10=5(5)-15
10=25-15
10=10
true
n=5
