Answer:
B will be the answer...
Step-by-step explanation:
The second equation in system B is only in terms of y, so we need to use elimination to eliminate the x term from the second equation in system A.
To do that, we need to multiply the first equation by 5.
5 (-x − 2y = 7)
-5x − 10y = 35
Add to the second equation. Notice the x terms cancel out.
(-5x − 10y) + (5x − 6y) = 35 + (-3)
-16y = 32
Combining this new equation with the first equation from system A will get us system B.
-x − 2y = 7
-16y = 32
The slope is 7/8.
Slope formula is the change in y over the change in x,
M=y2-y1 / x2-x1
M= -3 - (-10) / -2 - (-10)
Remember that two negatives equal a positive.
That makes the equation:
M= -3 + 10 / -2 + 10
M= 7/8
Answer:
Step-by-step explanation:
3p + 6p + 6p = 180 deg
15p = 180
p = 12
thus,
36 deg, 72 deg, 72 deg (ANS)
To find the are of a square, we simply square the value of a side
so..
Area = 25 square units
Answer:
-1
Step-by-step explanation:
Over 12 on the x axis it goes down 12 on the y axis so the rate of change is -1
