(3)(-5x+y=-3)
(5)(3x-8y=24)
-15x+3y=-9
15x-40y=120
3y=-9
-40y=120
-37y=111
Divide both sides by -37
y=-3
To solve for x. Choose one equation from the given and plug what you get in Y.
I'll choose, -5x+y=-3
So, -5x+(-3)=-3
-5x=0
Divide both sides by -5
x=0/-5
Hope, this helps.
Answer:
Step-by-step explanation:
1. The y-values in the table are constant, so the slope is 0. It is a horizontal line.
There is no x-intercept.
The y-intercept is (0, 1).
__
For lines in standard form, the intercepts can be found easily. The x-intercept is the value of x when y=0:
ax +0 = c
x = c/a . . . . x-intercept
Similarly, the y-intercept is the value of y when x=0:
0 +by = c
y = c/b
__
3. x-intercept = (-20/2, 0) = (-10, 0)
y-intercept = (0, -20/-5) = (0, 4)
__
4. x-intercept = (-6/1, 0) = (-6, 0)
y-intercept = (0, -6/-3) = (0, 2)
Plot these points and draw a line through them.
5.60 divided by 4 is 1.40$
The unit is 1.60
Answer:
y is 6.5 because it's kind of a ratio, you just need to find out what number to divide them by or multiply them by in this case, it was 13÷2 =6.5
