Answer:

x^2 + y^2 = 3^2

Step-by-step explanation:

Use the standard equation of a circle with center at (h, k) and radius r:

(x - 0)^2 + (y - k)^2 = 3^2, or

x^2 + y^2 = 3^2

The question is asking how many tenths are in one half. You need to divide one half by one tenth. To divide fractions you need to invert and multiply.

1/2 ÷ 1/10

Step 1: Invert and multiply

1/2 × 10/1 = 10/2

Step 2: Simplify

((7,-1) and (21,-5) what is the equation in slope intercept form?

mr_godi [17]

Answer:

y=-2/7x+1

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-5-(-1))/(21-7)

m=(-5+1)/14

m=-4/14

simplify

m=-2/7

y-y1=m(x-x1)

y-(-1)=-2/7(x-7)

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

y=-2/7x+2-1

y=-2/7x+1
