−10x+3y=5 ASAP<br> x=y−4 <br><br> x ?<br> y?

nexus9112 [7]

Answer:

x = 1 and y = 5

Step-by-step explanation:

Use substitution because you know that x = y - 4, and plug this into the first equation to get -10(y - 4) + 3y = 5, or -10y + 40 + 3y = 5. This is -7y = -35 so y = 5. Plug this into the 2nd equation to get that x = 1 and y = 5.

While watching a football game, Jordan decided to list yardage gained as positive integers and yardage lost as negative integers

koban [17]

Answer:

There is a loss of 2 yards.

Step-by-step explanation:

To find the overall gain or loss, we add or subtract there values.

Initially, we have 0 yards.

Records 14, so 0 + 14 = 14, that is, for now a gain of 14

Then loses 7, so 14 - 7 = 7, for now a gain of 7.

Then, 7 - 9 = - 2, so in all, there is a loss of 2 yards.

Find the coordinate of K' after a Glide reflection of the triangle: translation 4 units up and 4 units right then a reflection a

monitta

Answer:

a. (-1, 3)

Step-by-step explanation:

The "glide" 4 units right and up is the transformation ...

(x, y) ⇒ (x+4, y+4)

The reflection across y=1 is the transformation ...

(x, y) ⇒ (x, 2-y)

Combined, you have the transformation ...

(x, y) ⇒ (x +4, 2-(y +4)) = (x +4, -2-y)

Then, ...

K(-5, -5) ⇒ K'(-5 +4, -2-(-5)) = K'(-1, 3)

Answer:

see below

Step-by-step explanation:

The circumference is given by

C = pi *d

C = 15.5 pi

If we approximate pi by 3.14

C = 15.5 * 3.14

C =48.67

If we use the pi button

C =48.69486813
