Answer:

b

Step-by-step explanation:

In y=mx+b form, the b is the y-intercept, therefore where the line crosses the y-axis on the graph. In this graph, the line crosses the y-axis at 100. This means that the "b" value is 100. So far, our equation is y=mx+100.

Next, to find m, you go to any other point on the graph and see how much units (rise over run) you went to get there. I picked the point (2,150), You can see that it took me 1 unit up and 2 units to the right to get to that point, leading us to believe the slope is 1/2.

Finally, put everything together and you get the answer of y=1/2x+100 (the letters do not matter) :)

Question 8 (2 points)

SashulF [63]

Answer:

$\mathbf{x=\frac{1}{2}}$ is the solution to the equation: $4x+12-8x=-1+2x+10$

The statement is true.

Option A is correct.

Step-by-step explanation:

We need to determine if $x=\frac{1}{2}$ is the solution to the equation: $4x+12-8x=-1+2x+10$

Solving the equation first to find value of x

$4x+12-8x=-1+2x+10$

Combining like terms:

$4x-8x+12=2x+10-1\\-4x+12=2x+9$

Subtracting 2x on both sides

$-4x+12-2x=2x+9-2x\\-4x-2x+12=9\\-6x+12=9$

Now, subtracting 12 on both sides

$-6x+12-12=9-12\\-6x=-3\\$

Divide both sides by -6

$\frac{-6x}{-6}=\frac{-3}{-6}\\x=\frac{1}{2}$

So, we get $\mathbf{x=\frac{1}{2}}$

Therefore we can say that $\mathbf{x=\frac{1}{2}}$ is the solution to the equation: $4x+12-8x=-1+2x+10$

The statement is true.

Option A is correct.

Question 11 (Multiple Choice Worth 1 points

Diano4ka-milaya [45]

Answer:

$3\frac{4}{33}=3.\bar1\bar2$

Step-by-step explanation:

Given:

Simplify The given choice.

$3\frac{4}{33}=\frac{33\times 3 +4}{33}=\frac{99+4}{33}=\frac{103}{33}=3.1212121=3.\bar1\bar2$

$3\frac{8}{33}=\frac{33\times 3 +8}{33}=\frac{99+8}{33}=\frac{107}{33}=3.242424=3.\bar2\bar4$

$3\frac{10}{39}=\frac{39\times 3 +10}{39}=\frac{117+10}{39}=\frac{127}{39}=3.2564$

$3\frac{5}{39}=\frac{39\times 3 +5}{39}=\frac{117+5}{39}=\frac{122}{39}=3.12820$

Therefore, the first option $3\frac{4}{33}$ is correct.
