Which of the following are solutions to the system
{5x−2y=10
−2.5x+y=−5? Select two answers.
A.
(2,0)
B.
(−2,−10)
C.
(2,−5)
D.
(−2,5)
E. (0, 2)

A & B

Step-by-step explanation:

5x - 2y = 10 (1)

-2.5x + y = -5 (2)

When you multiply (2) by -2, you get (1), so there can be many solutions

To choose from the given options, plug in the values to check which ones satisfy the equation

5x - 2y = 10

A) (2,0)

5(2) - 2(0) = 10

10 = 10 (true statement)

B) (-2,-10)

5(-2) - 2(-10) = 10

-10 + 20 = 10

10 = 10 (true statement)

the answer is c.

for continuous functions, they continue in the same pattern and you have to find that pattern kinda like slope

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
