Solution
Step 1:
There are three types of systems of linear equations in two variables, and three types of solutions.
1. An independent system has exactly one solution pair. The point where the two lines intersect is the only solution.
2. An inconsistent system has no solution.
3. A dependent system has infinitely many solutions.
Step 2
Solve the systems of the equations using the substitution method
Final answer
The system is dependent so there are infinite solutions.
Equivalent
A.
This is because we start with the slope of 6. This is because it is the slope of the original equation (the number attached to x) and parallel lines have the same slope. Then you can use that along with the point to find the y intercept using slope intercept form (y = mx + b)
y = mx + b
10 = 6(4) + b
10 = 24 + b
-14 = b
So -24 must be the number at the end of the equation, making a the right answer.
Answer:
$425
Step-by-step explanation:
Let washer be w
Let dryer be d
If d =x then w=x +74
x+x+74=924
2x+74=924
2x=850
dividing both sides by 2
x=425 hence d which is the dryer is $425
Answer:
For example, a hydrogen atom has 0 charge because its two constituents are oppositely charged; and understand p + q as the number located a distance |q| from p, in the positive or negative direction depending on whether q is positive or negative.
