Answer: since the 5 is a negative you are subtracting it from 3
so 3 +(-5) is actually 3-5. which = -2
Step-by-step explanation:
Hope this helps
Answer:
1. g. $0.10 per square inch
2. c. $0.08 per square inch
3. f. $10
4. m. $8
5. h. 79 in²
6. j. 113 in²
Step-by-step explanation:
1. A = πr²
r = diameter ÷ 2 = 10 ÷ 2 = 5
A = π(5)² = 25π in² ≈ 78.53981
$8.00/25π = $0.10 per square inch
2. A = πr²
r = diameter ÷ 2 = 12 ÷ 2 = 6
A = π(6)² = 36π in² ≈ 113.0973355
$10.00/36π = 0.088419 = $0.08 per square inch

5. A = πr²
r = diameter ÷ 2 = 10 ÷ 2 = 5
A = π(5)² = 25π in² ≈ 79 in²
6. A = πr²
r = diameter ÷ 2 = 12 ÷ 2 = 6
A = π(6)² = 36π in² ≈ 113 in²
I believe your answer is D if i am wrong i am deeply sorry.
Step-by-step explanation:
Answer:
Translation of 1 unit left and 7 units up.
Solution:
A (3, -4) ~ A’ (2, 3)
Translation = 1 unit left and 7 units up.
Answer:
y = -2x - 1 ; slope = -2, y-intercept = (0, -1)
Step-by-step explanation:
to get the slope and y intercept, you need to put the equation into slope-intercept form: y = mx + b
the term mx is the slope of the line, and b is the y-intercept
to do this, you need to solve for y, so get y by itself by subtracting 8x from the left side
8x + 4y = -4
-8x. -8x
4y = -8x - 4
divide both sides by 4 to get y alone
4y/4 = y
-8x/4 = -2x
-4/4 = -1
y = -2x - 1 is the final equation
the slope of the line is -2 (also can be said as -2/1), and the line intercepts the y-axis at (0,-1)
