The value of y when x equals -15 in the equation (y = - 180 - 9(x)) is -45.
<h3>Copy and complete the table for x and y?</h3>
In a given function y = f(x) = bx - c, the value of y can be determined, if the value of x is known. All we have to do is to substitute the known value for x into the equation in order to determine the value of y.
From the given information:
y = - 180 - 9(x)
y = -180 - 9(-15)
y = -180 + 135
y = -45

Answer:
8) <em>x</em>=9
10) 23 degrees
Step-by-step explanation:
8) vertical angles are congruent to each other so we can set the expressions as such and solve:
<u>7x</u> + 3 = <u>10x</u> - 24
<u>3</u> = 3x<u> - 24</u>
<u>27</u> = <u>3x</u>
9 = x
10) since the angles are complementary they equal 90 degrees, so we can set the expression like this and solve for <em>x</em>:
<u>12x</u> + 7 + <u>6x</u> - 7 = 90
18x <u>+ 7 - 7</u> = 90
<u>18x</u> = <u>90</u>
x = 5
now we plug it back into the expression equivalent to the measure of angle O:
<u>6(5)</u> -7
<u>30 - 7</u>
23 degrees
Answer:
it goes up a by 5 everyday so it would be 19
Step-by-step explanation:
Answer:
First, we need to know the formula when a scale factor appears:
New coordinate = (scale factor)*(old coordinate)
So using this formula we have:
1) c' = (-2,1)*2/3
c' = (-4/3,2/3)
2) r = (-5,2)*2/3
r = (-10/3,4/3)
3) a = (-6,7)*2/3
a = (-4,14/3)
4) f = (-3,9)*2/3
f = (-2,6)
5) t = (-1,6)*2/3
t = (-2/3,4)
