Answer:

The expression for a line that passes throug the points (-2;3) and (2;7) is:

x - y = -5

Option C

Step-by-step explanation:

The expression for a line that passes through 2 differents points can be obtained by the following formula:

y - yo = m(x-xo)

The coordinate of the point Po(xo,yo) can be either of the given points. The value of m is calculated like:

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

Where x2 and y2 are the coordinates for the point P2 and x1 and y1 the  coordinates for the point P1. Assuming P1(-2;3) and P2(2;7), the value of m results:

m = (7-3)/(2-(-2)) = 4/4 = 1

Replacing m and the coordinates of P1 as the coordinates of Po, in the expression for the line we obtain:

y - 3 = (1)(x - (-2))

y - 3 = (1)(x+2)

y  = x + 2+ 3  

y = x + 5

-5 = x - y

x - y = -5

Nady [450]

Answer:

She can put a maximum of 10 boxes in the cart.

Step-by-step explanation:

Given that each cart that Debbie uses to move the boxes supports a maximum of 200 pounds, and that each box that she places in the cart weighs 20 pounds, to determine the maximum number of boxes that can fit in the cart, the following calculation must be performed :

200/20 = X

20/2 = X

10 = X

Thus, she can put a maximum of 10 boxes in the cart.

Jimmy's backyard is rectangle that is 18 5/6 yards long and 10 2/5 yards wide Jim buy sod in pieces that are 1 1/3 yard long and
g100num [7]

Answer:

111 pieces of soda

Step-by-step explanation:

step 1

Find the area of the rectangular backyard

The area of the rectangular backyard is equal to

A=LW

where

L=18\frac{5}{6}\ yd=\frac{18*6+5}{6}=\frac{113}{6}\ yd

W=10\frac{2}{5}\ yd=\frac{10*5+2}{5}=\frac{52}{5}\ yd

substitute

A=(\frac{113}{6})(\frac{52}{5})

A=\frac{5,876}{30}\ yd^2

step 2

Find the area of one piece of sod

The area of the rectangular piece of sod is

A=LW

where

L=1\frac{1}{3}\ yd=\frac{1*3+1}{3}=\frac{4}{3}\ yd

W=1\frac{1}{3}\ yd=\frac{1*3+1}{3}=\frac{4}{3}\ yd

substitute

A=(\frac{4}{3})^2\\\\A=\frac{16}{9}\ yd^2

step 3

Find the pieces of sod needed

To find out how many whole pieces of sod will Jim need to buy to cover his backyard, divide the area of the backyard by the area of one piece of soda

so

\frac{5,876}{30} : \frac{16}{9}=\frac{52,884}{480}=110.175

Round up

111 pieces of soda

1. What is the center and radius of the circle?<br> (x-4)² + (x-7) ² - 49
tester [92]

Answer:

Center at (4, 7) and radius is √49, or 7

Step-by-step explanation:

Didn't you mean (x-4)² + (y-7) ² = 49?

Comparing          (x-4)² + (y-7) ² = 49

to                          (x - h)^2 + (y - k)^2 = r^2, we see that the center is at (h, k)  =>  (4, 7) and that the radius is √49, or 7.
