Answer:

just add the equation and solve it then the value of X could be found then put the value of X and the value of y can be found. Just like in the below

Step-by-step explanation:

X+y=3 ------------ equation 1

4x-y=7 ------------ equation 2

adding equation 1 and 2

X+y=3

+ 4x-y=7

-----------------

5x = 10

X = 10/5

X = 2

putting the value of X in equation 1

or, 2+y=3

or, y = 3-2

Thus, y = 1

Answer:

value of x is 22°

Step-by-step explanation:

It is 22 degrees because it is originally a right angle which is 90°. If you do 90-68 you would get 22. The reason you would subtract is because 68 is already used of the 90° angle. My explanation isn't that good.

QUESTION 10<br> What is the slope of a line that is parallel to the line<br> 2y = 3x - 5
Darya [45]

Answer:

Slope: 1.5

Step-by-step explanation:

We first have to find what y is equal to. That means we take 3x - 5 and divide it by 2. We get 1.5x - 2.5. Since the lines are parallel and they have the same slope and different y - intercepts, we know that the slope will be equal.
