Answer:
<h3>B. -84</h3>
Step-by-step explanation:
Taking the determinant of the matrices we will have;
= 4x(5y) - 2x(3y)
= 20xy - 6xy
= 14xy
Given x = -2 and y = 3
Determinant = 14(-2)(3)
Determinant = -28*3
Determinant = -84
Answer:
Slope (m) is the number being multiplied by x (make sure you include the sign in front of it).
y- intercept (b) is the number other than the x
Step-by-step explanation:
Answer:
x = 7, x = -10
Step-by-step explanation:
Use the quadratic formula.
Solve.
x = 7, x = -10
You can also factor if you want - that is a faster method.
The answer is 6 because you add the 1 and the 2 first and then multiple to get 6. I don’t know why you put the division sign in front of the 2 though.
