Answer:b=7-2-=2
Step-by-step explanation:
Answer:
135°
Step-by-step explanation:
Because the lines are parallel, <1 and <3 are the same.
Answer:
A) y>=-1
Step-by-step explanation:
The line itself is y=-1, but it is also filled in. Therefore, we are down to either A or C as the right answer
Since (0,0) is a solution to the inequality as indicated by the shade, we know that since y=0 in the origin, 0 is greater than -1, so therefore A is the correct answer.
Answer:
x = 2, y = 3
Step-by-step explanation:
x + y = 5
Shift y to the other side and change to (-y).
x = 5 - y --- Equation 1
x - 2y = -4 --- Equation 2
Substitute x = 5 - y into Equation 2:
x - 2y = -4
5 - y - 2y = -4
Shift 5 to the other side and change to (-5).
-y - 2y = -4 - 5
Evaluate like terms.
-3y = -9
Divide both sides by -3.
y = -9 ÷ -3
y = 3
Substitute y = 3 into Equation 1:
x = 5 - y
x = 5 - 3
x = 2
