hope I helped Kkkkkkkk
First find the slope:
m = ( 2 - 1 ) / ( 0 - (-1) ) = 1 / 1 = 1
Set up slope-intercept form:
y = 1·x +2
Now move x and y to the left and leave 2 on the right:
-x + y = 2
This is also equivalent to x - y = -2, so that just depends if you want your x coefficient to be positive or negative.
Answer:
The ordered pair solution is (-2, 8)
Step-by-step explanation:
y = -4x ------ equation 1
y = 2x + 12 ---- equation 2
We solve for x by substitution;
Substituting the value of y into equation 2;
y = 2x + 12
-4x = 2x + 12
-4x -2x = 12
-6x = 12
Divide by -6
x = 12/(-6)
x = -2
From equation 1;
y = -4x
Substituting the value of x;
y = -4×(-2)
y = 8.
PROOF;
y = -4x
8 = -4*(-2)
8 = 8
Now, a whole, will be 15/15 or 1 whole.
now, the sprinkler does 1/15 of the lawn in 1/3 of an hour, how long will it be to do the whole 15/15?
