Which graph represents the solution to the given system? (1 point) Y=-3x+4 and y=2x-1

1 answer:

8 0

-3x + 4 = 2x - 1
5x = 5
x = 1

When x = 1, y = 1

I'm not sure about the graph, but I solved them simultaneously? If you meant which graph but forgot to upload a photo attachment, look where it crosses the Y axis. If it is 4, it will be the first equation, if it crosses at -1, it will be the second equation

Alex is 4 years younger than 2 times his sister's age. Write a rule that represents Alex's age x as a function of his sister's a

Vesna [10]

Answer:

y = 2x - 4; Alex is 18.

Step-by-step explanation:

Since Alex is 4 years younger than 2 times his sister's age, and his sister is y and Alex is x, the function of y to x must be y = 2x - 4.

According to the rule, if Alex's sister is 11, Alex is 2 times that minus four. If you calculate that, you get

11 * 2 = 22

22 - 4 = 18

So Alex is 18 if his sister is 11.

The side of the parallelogram in the figure above are given in cm.

GrogVix [38]

solution

or, 2 x + y = 5 y - 8 being opposite side of

parallelogram

or , 2x =5 y - y - 8

or, 2x = 4 y - 8

or, x = 4y - 8/2

or,. x = 2y- 4

therefore, 2x + y is equal to 5 y - 8 Being the opposite side of a parallelogram

now,

3y + 2 x is equal to 4x - 3 being opposite side of a parallelogram

or, 3y + 2 x-4x = -3

or,. 3y -2x = -3
