Acircle is centered at the point (-3, 2) and passes through the point (1, 5). the radius of the circle is ? units. the point (-7, ? ) lies on this circle.

radius of the circle is 5 units.

the circle passes through the points (-7,5) and (-7, -1).

Step-by-step explanation:

The center of the circle is  (-3, 2) and it passes through (1,5)

The standard form of a circle is given by

Here, we have

h = -3, k = 2, x= 1, y = 5

Plugging these values, we get

Therefore, the radius of the circle is 5 units.

Now, we have been given that

x = -7 and we have to find the value of y.

The equation of circle is

Plugging, x = -7 and find y

Therefore, the circle passes through the points (-7,5) and (-7, -1).

answer: d. $20

step-by-step explanation:

just took the test

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
