Answer:
1
Step-by-step explanation:
=> 
<u><em>Where a = 2, b = 3</em></u>
=> 
=> 4(4) - 4(6) + 9
=> 16 - 24 + 9
=> -8 + 9
=> 1
You would subtract 4 from both sides. Then it would be 3n = 3. You would then divide each side by 3. The answer you would get is n = 1.
Answer:
Step-by-step explanation:
In non-mathematical form, the question is asking $8.80 is what percent of $440. N will equal the percent. So, you would set up the equation like this: 20 = N · 440
You need to solve the equation.
20/440 = N · 440/440
0.045 repeating = N
Rounded, the sales tax rate would be 4.5%
Answer:
x=1
Step-by-step explanation:
-8x+2(4+2)=4
-8x+2×6=4
-8x+12=4
-8x=4-12
-8x= -8
we multiply both sides with (-1) to get a positive number in the x side
-8x= -8 / ×(-1)
8x=8
x=8/8
x=1

Answer:
$0 -- y-intercept
$10 per hour -- slope
Step-by-step explanation:
We would need to see grid lines on the graph, or the point in the upper right corner to be sure. It appears as though the slope is about $40 / 4 h, or $10 per hour.
The y-intercept is the point at lower left, (0, 0).
