Answer:
x = 9
Step-by-step explanation:
(whole secant) x (external part) = (tangent)^2
(24+3) * 3 = x^2
27*3 = x^2
81 = x^2
Take the square root of each side
sqrt(81) = sqrt(x^2)
9 =x
Answer:
y - 4 = 0
Step-by-step explanation:
They give you the y coordinate, 4, and the x coordinate as 0.
Put 4 in as y.
4 - 4 = 0. That means x = 0 and that is right.
To make sure it has a slope of zero, subtract 4 on both sides.
You get : y = 4. This means that the line will be straight and it will have a slope of zero.
C because the highest and lowest Y values are at -7 and 4.
<h3>:- Solution</h3>
-8x - 9 > -21
Move -9 to right side
-8x > -21 + 9
-8x > -12
x < -12/-8
x < 3/2
the answer to -8x - 9 > -21 is <u>x</u><u> </u><u><</u><u> </u><u>3</u><u>/</u><u>2</u>
First you would take both radius' and add them. Once you add them, subtract the sum by 42. that will give you the distance between the gap of the circles. now that you have that distance, add 19 and 11 and your result is your final answer.
