Answer:

Step-by-step explanation:
Cost of 4 TVs = $ 680
<u>Finding</u><u> </u><u>the</u><u> </u><u>cost</u><u> </u><u>of</u><u> </u><u>1</u><u> </u><u>TV</u>

<u>Finding</u><u> </u><u>the </u><u>cost</u><u> </u><u>of</u><u> </u><u>7</u><u> </u><u>TVs</u>
Since, the cost of 7 TVs is more than that of 1 TV. So, the cost of 1 TV is multiplied by 7

Hope I helped!
Best regards! :D
For this case, what you should know is that a linear function has a constant average rate of change, because its slope is constant.
Table number two from left to right represents a linear function.
The line is:
y-yo = m (x-xo)
Where
The slope is:
m = (0 - (- 5)) / (2-1)
m = 5/1
m = 5
The line is:
y-0 = 5 (x-2)
Rewriting:
y = 5x-10
Answer:
Table two from left to right.
The equation is:
y = 5x-10
Answer:
Megan will have to pay $2, 260 for surgery.
Step-by-step explanation:
1. Translate percent into decimal:
90% -> 0.9
2. Multiply (to find out how much the insurance company pays):
(0.9)(14, 600) = 13, 140
3. Subtract:
14, 600 - 13, 140 = 1, 460
4. Add (to find out how much Megan pays):
1, 460 + 800 = 2, 260
A triangle has a total angle of 180 degrees. Since we know
that angle X = angle N = 20 degrees and angle Y = angle M = 75 degrees,
therefore angle Z or angle L is equal to:
angle L = 180 – 20 – 75
<span>angle L = 85
degrees</span>
Therefore w is:
angle L = 5 (w – 2)
5 (w – 2) = 85
w – 2 = 17
<span>w = 19</span>
