7x + 3y = -1
x + y = -3.....x = -3 - y

7(-3-y) + 3y = -1
-21 + -7y + 3y = -1
-4y = -1 + 21
-4y = 20
y = 20/-4
y = -5

x + y = -3
x - 5 = -3
x = -3 + 5
x = 2

so ur 2 numbers are : 2 and -5

Find the perimeter of the figure. Please
kramer
The dashed line labeled as 6 is the diameter of the circular part of the figure.

The circumference of a circle is it's perimeter, so we need to find half the circumference first.

The formula for circumference is PI x diameter, since we need half we will divide the total circumference by 2.

Circumference = 3.14 x 6 = 18.85 / 2 = 9.425

Now we add that to the other 3 dimensions for total perimeter:

9.425 + 9 + 9 +6 = 33.425

You may need to round the answer, you didn't say if it needed to be rounded a certain way.

Can someone help me with this question ASAP
sattari [20]
Let m be the slope:

m=(y₂-y₁)/(x₂-x₁)

solve for c:

1/6=(9-c)/(1-7)

1/6=(9-c)/-6

-1=9-c

-10=-c

c=10
