Answer:
Step-by-step explanation:
y=-3+7
Answer:
Step-by-step explanation:
30/2 = 15
15 x 5 = 75
The number is 75.
We know that
<span>Mya is paid $960 a week to walk 20 dogs
then
</span>$960/20 dogs-----> $48 for one dog each week
the answer is
the cost to walk one dog each week is $48
The answer would be A. When using Cramer's Rule to solve a system of equations, if the determinant of the coefficient matrix equals zero and neither numerator determinant is zero, then the system has infinite solutions. It would be hard finding this answer when we use the Cramer's Rule so instead we use the Gauss Elimination. Considering the equations:
x + y = 3 and <span>2x + 2y = 6
Determinant of the equations are </span>
<span>| 1 1 | </span>
<span>| 2 2 | = 0
</span>
the numerator determinants would be
<span>| 3 1 | . .| 1 3 | </span>
<span>| 6 2 | = | 2 6 | = 0.
Executing Gauss Elimination, any two numbers, whose sum is 3, would satisfy the given system. F</span>or instance (3, 0), <span>(2, 1) and (4, -1). Therefore, it would have infinitely many solutions. </span>
