Solve the system. 4x-6y=-26 -2x+3y=13 a. 5,1 b. 1,-5 c. -5,1 d. infinite number of solutions

4x - 6y = -26

-2x + 3y = 13     Multiply this by 2:-

-4x + 6y = 26      Add the first equation to this one. We get:-

0 + 0 = 0

Both equations graph is the same lien.

Infinite number of solutions

Here in the above equation a1=4 , b1=-6 , c1=26

Like that a2=-2 , b2=3 , c2=-13

Here

So it have infinitely many solution. (Answer)

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
