Answer:
The solution to the system would be (3, -1)
Step-by-step explanation:
You can find the solution to this system by using the elimination method. To do that, start by multiplying the top equation by -5 and then adding it through.
-5x + 20y = -35
5x + 9y = 6
-----------------
29y = -29
y = -1
Now that we have the value of y, we can plug it into either equation and find the x value.
x - 4y = 7
x - 4(-1) = 7
x + 4 = 7
x = 3
Answer:
Cannot be determined
Step-by-step explanation:
All that's shown is that the three corresponding angles are equal. By AAA similarity, these triangles are similar. But they could be dilated and the angle measures would remain the same, without the side lengths being equal. This is why you can't determine whether or not these triangles are congruent.
Pls give me brainliest
The slope of the line is -13
y=x-1 is 2=3-1
y=-x+5 is 2=-3+5
Step-by-step explanation:
3=x and 2=y. x y
(3,2)
Now you just substitute the variables (which are the letters) by the numbers of x (3) and y(2) for both of equations
11y + 34 = 7y - 32
4y + 34 = -32
4y = 66
y = 66/4 = 14.333.
