Answer:
c. 10
Step-by-step explanation:
Eliminate parentheses using the distributive property.
3(b+4) -2(2b+3) = -4 . . . . given
3b +12 -4b -6 = -4 . . . . . parentheses eliminated
-b +6 = -4 . . . . . . . . . . . . collect terms
-b = -10 . . . . . . . . . . . . . . subtract 6
b = 10 . . . . . . . . . . . . . . . . multiply by -1
_____
The rules of equality require that any operation you perform on one side of the equal sign must also be done on the other side. So when we say "subtract 6", we assume you know that means "subtract 6 from both sides of the equation", for example.

Answer:
Step-by-step explanation:
<u>When the line is given in standard form:</u>
- ax + by = c, it has slope of -a/b
<u>Given line:</u>
<u>It has a slope:</u>
A line perpendicular to the given should have a slope m = 1 as negative reciprocal to the given
<u>Let's see which line has the slope of 1:</u>
- 1. m = -(-1)/6 = 1/6 - NO
- 2. m = -4/4 = -1 - NO
- 3. m = -2/4 = -1/2 - NO
- 4. m = -(-2)/2 = 1 - YES
Correct option is D
First, look at my attachmentThe dump truck makes imaginary right triangle.
From the right triangle, we can find the h with sin ratio of the triangle. h/b = sin of angle
h = b × sin of angle
(h stands for height, b stands for bed)
PART A: If the angle is 45°h = b × sin 45°
h = 15 × 1/2√2
h = 15 × 0.707
h = 10.607
h = 10.6
The height is approximately 10.6 ft.
PART B: If the angle is 30°h = b × sin 30°
h = 15 × 1/2
h = 7.5
The height is 7.5 ft.
PART C: If the angle is 60°h = b × sin 60°
h = 15 × 1/2√3
h = 15 × 0.866
h = 12.990
h = 12.99
The height is approximately 12.99 ft.
