Answer:
24
Step-by-step explanation:
The solution is (5, 15)
Multiply the second equation by 2 and then add through.
3x + 2y = 45
8x - 2y = 10
-----------------
11x = 55
x = 5
Then plug in to get the y value
3(5) + 2y = 45
15 + 2y = 45
2y = 30
y = 15
5. A
6. No, 1/5(25x+15)-7x= -2x+3
-2(x-5)= -2x+10
-2x+3 is not equal to -2x+10
The function rule for x is +1. When you want to get the next number in the set, you add one to the previous number. For example, -1 + 1 = 0.
The function rule for y is - 5. When you want to get the next number in the set, you subtract five to the previous number. For example, 9 - 5 = 4.
Hope this helps!
