What it is side ways i can help sory
2(2x+1)= (2 x 2x) + (2 x 1) = 4x + 2
Slope of the line is -7
Step-by-step explanation:
- Step 1: Find slope of the line using formula, m = (y2 - y1)/(x2 - x1). Here, x1 = 7, y1 = -41, x2 = -15 and y2 = 113
⇒ m = (113 - -41)/(-15 - 7)
= 154/-22 = -7
<span>In finding the solution for x, the idea is to isolate the variable on one side of the equation
5 - 3x = 2x + 9 |3x is added to the equation first
5 = 5x + 9 | 9 is subtracted from EQ second
-4 = 5x </span>
Answer: Choice B
y = (x+3)^2 - 1
==================================================
Recall that vertex form is y = a(x-h)^2 + k with the vertex being (h,k)
From the given graph, it shows that (h,k) = (-3,1) is the vertex. So we plug this pair of values into the general function above to get
y = a(x-h)^2 + k
y = 1(x-(-3))^2 + (-1)
y = (x+3)^2 - 1
which is the final answer
note: a = 1 is the case for all four answer choices, so we don't have to worry about the value of 'a'
