2x + y = 3

x = 2y - 1

2(2y-1)+y=3

4y-2+y=3

5y=5

y=1

x=2(1)-1

x=1

x = 2y - 1

2(2y-1)+y=3

4y-2+y=3

5y=5

y=1

x=2(1)-1

x=1

Shawna and Kai both work at the same pet store. On Monday, Shawna counts 52 birds and cats in the store. For the same animals, Kai counts 138 legs. Let b = number of birds in store

52-b = number of cats in store

2b= number of the bird's legs Kali counts

4(52-b) = number of cat's legs Kali counts

2b+4(52-b)=138 ; 2b+ 208 -4b =138 ; 2b = 208-138 ; 2b =70; b =35

52-b ; 52 -35 =17 ; There are 35 birds and 17 cats in the store

52-b = number of cats in store

2b= number of the bird's legs Kali counts

4(52-b) = number of cat's legs Kali counts

2b+4(52-b)=138 ; 2b+ 208 -4b =138 ; 2b = 208-138 ; 2b =70; b =35

52-b ; 52 -35 =17 ; There are 35 birds and 17 cats in the store

Given: x + y = 10.
If x = -21, what is y?
11
-31
31 **Weegy:** Given: x + y = 10. If x = -21, y is 31.
Solution:
-21 + y = 10;
y = 10 + 21; y = 31 **User:** Given: x + y = 15.
Which of the following are ordered pairs of this equation?
{(-3, 14),(0, 15),(3, 16)}
{(-3, 16),(0, 15),(3, 14)}
{(16, -3),(15, 0),(14, 3)} (More)

y = -x + 15

y = -(-3)+15 = 18: (-3,18) ; FAlse

y = -(0)+ 15 = 15: (0,15)

y = -(3) +15 = 12: (3,12), FAlse

A and B are False

y = -(16)+15 = -1: (16, -1) ; FAlse

y = -(15)+15 = 0: (15,0)

y = -(14)+15 = 1: (14,0)

C is also False.

Jake earns $7.50 per hour working at a local car wash. The function, ƒ(x) = 7.50x, relates the amount Jake earns to the number of hours he works. Write the inverse of this relation.
**Weegy:** Jake earns $7.50 per hour working at a local car wash. The function, ƒ(x) = 7.50x, relates the amount Jake earns to the number of hours he works. The inverse is:
y = x / 7.50. Solution: f ( x ) = y;
y = 7.50 x;
x = y / 7.50. (More)
