Answer:

y = $\frac{3}{3}$ x - 5

y = 2x + 5

Step-by-step explanation:

In linear equations, both variables x and y must have the exponent of 1 (i.e. they cannot have a small number at the top-right). And they cannot be in the exponents (i.e. cannot be the small number at the top-right).

What is 7•8+1•40. Explain your answer

zaharov [31]

Answer:

Step-by-step explanation:

We will use the order of operations to solve the equation

7×8+1×40

multiplication before addition, so we do this first:

7×8=56

We change the equation to this:

56+1×40

Then we multiply:

1×40=40

We change the equation to this:

56+40

Then we add to solve:

56+40=96

Solve the system by graphing.

suter [353]

Answer: Option A. The solution set is (4,5)

Step-by-step explanation:

Solve the equation for y to obtain the form of the equation of the line.

You have:

y=-x+9 (The slope is -1 and the y-intercept is 9)

y=x+1 (The slope is 1 and the y-intercept is 1)

When you graph it you obtain the graph shown in the figure attached.

The solution is the intersection of the lines.

Then, the solution set is (4,5)
