2x-3y=13...(1)
2x+4y=-8...(2)
Multiply equation 2 by -1 to eliminate x
2x-3y=13
+ -2x-4y=8
—————
-7y=21
y=-3
Substitute y=-3 into equation 2
2x+4(-3)=-8
x=2
Therefore, the solution to the system is (2, -3)
Answer:
Step-by-step explanation:
Angle A and 50 will combined have an angle of 180
Angle A = 180-50
Angle C is opposite of angle A and both will be equal. Same with Angle B and it's opposing Angle.
You got this!
I believe it’s whole natural real and an integer
Answer:
standard form is 45x -12y -100 = 0.
Step-by-step explanation:
Given the equation is -3/2x=-2/5y-10/3.
Finding common denominator, L.C.M.(2,5,3) = 30.
Multiplying both sides by 30.
30*(-3/2x) = 30*(-2/5y-10/3)
-45x = -12y -100
Moving all terms on left side, keeping right side equal to 0.
-45x +12y +100 = 0
Making x's coefficient positive by changing all signs.
45x -12y -100 = 0
Hence, standard form is 45x -12y -100 = 0.
Answer:
P = 308
Step-by-step explanation:
33/P = 3/28 just cross multiply
3P = 33 (28)
P = 924 / 3
P = 308
