Step-by-step explanation:
If each clock radio costs $83.95 + taxes ($4.49), each clock radio has the real cost of $88.44
Therefore if you multiply the real cost of the 3 pieces, you'll get the result:
$88.44 x 3 = $265.32
Answer:
$265.32
Step-by-step explanation:
Let's pick two points on the line: 
and 
Let's calculate the slope of this line using these points:
With this value of the slope, we can write the general slope-intercept form of the equation as
To solve for the y-intercept b, let's use either P1 or P2. I'm going to use P2:
Therefore, the slope-intercept form of the equation is
Answer:
13a
Step-by-step explanation:
9a + 3a + a = 13a
Answer:
x = 1
Step-by-step explanation:
Given:
We are asked to solve for x when the function is equal to zero.
<u>We should have</u>: 0 = -4x + 4
<u>Solve</u>
1. Subtract 4 from both sides
0 - 4 = -4x + 4 - 4
-4 = -4x
2. Divide both sides by -4
-4 ÷ -4 = -4x ÷ 4
1 = x
