Answer:
y + 2 = 2/3(x + 2)
Step-by-step explanation:
Slope = 2/3 (rise/run)
Point: (-2,-2)
y - - 2 = 2/3 (x - - 2
(4/7) / (3/-8)...when dividing fractions, flip what u r dividing by, then multiply
4/7 * - 8/3 =
- 32/21 <===

Answer:
vertex : (-5/2, -53/4)
solutions: (-(5-sqrt53)/2, 0) (-(5+sqrt53)/2, 0)
Step-by-step explanation:
Answer:
k = 13The smallest zero or root is x = -10
===============================
note: you can write "x^2" to mean "x squared"
f(x) = x^2+3x-10
f(x+5) = (x+5)^2+3(x+5)-10 ... replace every x with x+5
f(x+5) = (x^2+10x+25)+3(x+5)-10
f(x+5) = x^2+10x+25+3x+15-10
f(x+5) = x^2+13x+30
Compare this with x^2+kx+30 and we see that k = 13
x^2+13x+30 = 0
(x+10)(x+3) = 0
x+10 = 0 or x+3 = 0
x = -10 or x = -3
The smallest zero is x = -10 as its the left-most value on a number line.
Step-by-step explanation: Hope this helps kind of.
