Consider the following equations - x - y = 1
y = x + 3

If the two equations are graphed at what point do the lines representing the two equations intersect?

1) (-1, 2)
2) (-2, 1)
3) (1, -2)
4) (2, -1)

​

2) (-2,1)

Step-by-step explanation:

Solve using the substitution method -x-(x+3)=1 using this equation you would find x which is -2

Substitute -2 into the given equation, y=-2+3   y=1

Therefore, The answer is (-2,1)

It would be greatly appreciated if you gave the the brainlest

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
