Answer:
x>= -46/9 (x greater than or equal to -46/9)
Step-by-step explanation:
when translating the question, at most means that it is less than or equal to the value being named, therefore the equation is 9x+21<= -25
to begin solving we subtract 21 from both sides and get 9x<=-46
then when we divide by 9 we have to flip the less than sign because we have to flip it if we multiply or divide.
This gives us the answer, x>=-46/9 which does not simplify any further
Your answer should be 44.84

The equation of a circle is written as (x-h)^2 + (y-k)^2 = r^r
H and k are the x and y coordinates of the center of the circle and r is the radius.
You are given the diameter coordinates so find the halfway point for the center then calculate the radius
Midpoint = (x1 +x2)/2, (y1 + y2)/2
Midpoint = (7 + -1)/2, (-3 +7)/2
Midpoint = 6/2, 4/2
Midpoint = 3,2
So h = 3 and k = 2
Now find radius by finding the distance between the center point and an end point.
Distance = sqrt(41)
Equation of the circle:
(X-3)^2 + (y-2)^2 = 41

Given: In ΔMNO and ΔQRS
To prove that the triangles are similar by the SSS similarity theorem [corresponding sides of similar triangles are proportional], there must be the third pair of corresponding sides,
That must be and
