Step-by-step explanation:
<h3>y + 7x = 9 </h3>
<h3>y = 9 - 7x , (x = - 1) </h3><h3>y = 9 - 7 (-1)</h3><h3>y= 9 - (-7)</h3><h3>y = - 16</h3>
<h3>y = 9 - 7x , (x = 0)</h3><h3>y = 9 - 7(0) </h3><h3>y = 9 - 0</h3><h3>y = 0</h3>
<h3>y= 9 - 7x , (x = 2) </h3><h3>y = 9 - 7 (2) </h3><h3>y = 9 - 14</h3><h3>y = - 5</h3>

Answer:
y=9-7x
If x= -1, y=16
If x= 0, y=9
If x=2, y= -5
Step-by-step explanation:
Because you are solving the equation for y, you want to have y by itself on one side. The only way to do that in this problem is by subtracting the 7x on both sides.
y+7x=9
-7x -7x ---> y=9-7x
The next part of the question says to find the value of Y for each value of X. Using the given X values, we plug them into the equation we just got in order to find Y.
y=9-7(-1) ----> y=16
y=9-7(0) ----> y=9
y=9-7(2) ----> y=-5

The rule is n + 5
So we have that
an = n + 5
Where n is the term, that said we want the 1st, 2nd, 3rd, 4th and 10th term
a1 = 1 + 5 = 6
a2 = 2 + 5 = 7
a3 = 3 + 5 = 8
a4 = 4 + 5 = 9
a10 = 10 + 5 = 15
The answer should be approximately 0.4

<h2>
C = 113.04 m </h2><h2>
</h2>
Step-by-step explanation:
circumference of a circle = 2πr
where
radius (r) = 18m
π = 3.14
plugin values into the formula
C = 2 (3.14) 18
C = 113.04 m
72 inches is 6 feet, and there are 5280 feet in a mile, so you divide 5289 by 6 to get 880 rotations per mile
