the answer is b
b works for each equation
Step-by-step explanation:
Answer:
x = 3
Step-by-step explanation:
8z = 2x + 18
6x = 18
x = 3
y = mx + b
-3 = -2(-5) + b
-3 = 10 + b
-13 = b
y = -2m - 13
The line would pass through -13 on the y-axis and it would go down 2 and move to the right 1 for every new point.
Hope this helps! ;)
Answer:
90 is the orrect answer because I said so
Step-by-step explanation:
Isolate one variable in the system of equations. Use substitution to create a one-variable equation. Then, set the quadratic equation equal to zero and find the discriminant. If the discriminant is negative, then there are no real number solutions. If the discriminant is zero, then there is one real number solution. If the discriminant is positive, then there are two real number solutions.
