How to find thr answer: The formula is y=x+2. What you need to do is find the graph from the choices that has a point marked right at the 2 on the y-axis (the vertical line), then the x is considered 1x. That's the slope, you count up one box and then one box to the left because it the rise over run (imagine a staircase, the part that makes one of the steps higher than the other is the rise and where you put your feet is the run). The answer will be B.
Answer:
A positive integer is greater than a negative integer. Therefore, 2 is greater than –4. ... To compare two negative integers, the negative integer with the smaller number is greater.

Answer:
y = - 3x² - 24x - 60
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (- 4, - 12 ), thus
y = a(x + 4)² - 12
To calculate a substitute (- 7, - 39) into the equation
- 39 = a(- 7 + 4)² - 12 ( add 12 to both sides )
- 27 = 9a ( divide both sides by 9 )
- 3 = a
y = - 3(x + 4)² - 12 ← in vertex form
Expand (x + 4)²
y = - 3(x² + 8x + 16) - 12
= - 3x² - 24x - 48 - 12
y = - 3x² - 24x - 60 ← in standard form
= - 3(x²
Answer:
140.37 in²
Step-by-step explanation:
C = 2πr
42 = 2πr
21 = πr
r = 21/π
A = πr²
A = π × (21/π)²
≈ 140.37 in²
