Step-by-step explanation:

(-2,3)-x1,y1

6,r -x2,y2

slope(m)=3/2

m= y2-y1/x2-x1

3/2= r-3/8

r=15

the basketball team sold t shirts and hats as a fundrasier they sold a total of 23 items and made a profit of 246 the made a pro
Gnesinka [82]

s - the number of the t-shirts;

h - the number of hats:

The system of equations:

s + h = 23

10 s + 12 h = 246

--------------------------

s = 23 - h

10 * ( 23 - h ) + 12 h = 246

230 - 10 h + 12 h = 246

2 h = 246 - 230

2 h = 16

h = 16 : 2

h= 8

s = 23 - 8

s = 15

Answer: The basketball team sold 15 t-shirts and 8 hats.

Find an equation of the circle having the given center and radius.<br> Center ( - 1, 1), radius 7
suter [353]

Answer:

(x+1)^2 + (y+1)^2 = 49

Step-by-step explanation:

We can write the equation of a circle as

(x-h)^2 + (y-k)^2 = r^2

where (h,k) is the center and r is the radius

(x- -1)^2 + (y- -1)^2 = 7^2

Simplifying

(x+1)^2 + (y+1)^2 = 49

Rachel multiplied each side of x ≥ 2 by 3. She wrote the result as 3x ≤ 6. Explain the error Rachel made.
andrey2020 [161]

Answer:

Her mistake was to change the inequality sign from ≥ to ≤.

The sign only changes when you multiply or divide both sides of an inequality by a negative number.
