8 is b because a circle is 360.
The square root of 81 is 9. 9*9=81. The length is 9 inches.
Answer:
42.
Step-by-step explanation:
y / 4 = 10.5
To isolate y we multiply both sides of the equation by 4:
4*y/4 = 4 *10.5
y = 42.
Answer:
x = 4, x = 8
Step-by-step explanation:
Given
(x - 7)(x - 5) = 3 ← expand factors using FOIL
x² - 12x + 35 = 3 ( subtract 3 from both sides )
x² - 12x + 32 = 0 ← in standard form
(x - 4)(x - 8) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x - 8 = 0 ⇒ x = 8
The equation of the image line is y= -0.5x.
When a line is reflected in a certain line, in this case the original line is reflected in the line y=-2, we simply flip it to the other side with respect to the line to which it is reflected. If you are going to graph it, you can see that the distance of the original line (y= 0.5x-4) from the line to which it is reflected (y=-2) and the distance of the reflected line (y=-0.5x) are symmetric.
