Answer:
The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect.
Step-by-step explanation:
The measure of angle 1 is (20-10)/2= 10/2= 5 degrees
Answer:
21
Step-by-step explanation:
13x2=26-5=21 so thats how I got the answer
No, because the sum of the total angle measure (or whatever it is called) is 720°, but those numbers only add up to 710°
Answer:
A
Step-by-step explanation:
Start with variable x.
4x - 6y = 28
Substitute the variables for numbers.
4(1) - 6(-4) = 28
Solve the new equation
4 + -24 = 28
Move to the second equation with variable y.
8x - 4y = 24
Substitute variables
8(1) - 4(-4) = 24
Solve
8 - (-16) = 24
The answer is A, x = 1, y = -4
