Answer:
Step-by-step explanation:
<u>Perpendicular lines have negative reciprocal slopes, so the line is:</u>
<u>Finding the value of b, using the given point (-9, -2)</u>
- -2 = -1/3*(-9) + b
- -2 = 3 + b
- b = -2 - 3
- b = -5
<u>The line is</u>
Answer:
x = -2
Step-by-step explanation:
x+8 = 2x +10
-2x + x = 10-8
-x = 2
divide both side by -1
answer -- x = -2
Answer:
<h2>(-5, -28)</h2>
Step-by-step explanation:
The vertex form of a quadratic function <em>f(x) = ax² + bx + c</em>:
f(x) = a(x - h)² + k
(h, k) - coordinates of a vertex
We have <em>f(x) = x² + 10x - 3</em> in the vertex form <em>f(x) = (x + 5)² - 28</em>.
f(x) = (x - (-5))² + (-28) → h = -5, k = -28
