V= (4x2)   x    (2x) x   (2x^2+x +7)
        8    (2x) (2x^2+x+7)
V= 32x^3   +16x ^2  +112 x

You can also factor out an x and a 16

Write the equation of the line?<br><br><br><br> write the equation in standard form.
vlabodo [156]
Answer: y= 1

This because the line has no slope so the equation really looks like this if we were to follow the y=mx+b format.

y=mx+b
y= 0x + b

because the number "0" multiplied by any value is still zero we can exlude that from the final equation of the line. In this case since m=0, the line is y=b.

b is the y intercept, or the value of y when x = 0.

So, because y=1 when x is 0, "b"= 1

y=b
y=1

Any questions?

A system of equations is shown below. Which of the following statements describes the graph of this system of equations in the (
ollegr [7]

The given system of equations represent a single line with positive slope. So option C is correct.

<u>SOLUTION: </u>

Given system of equations are

\begin{array}{l}{3 y-5 x=15 \rightarrow(1)} \\\\ {6 y-10 x=30 \rightarrow(2)}\end{array}

Now, if we observe, (1) \times 2 \rightarrow(2) multiplying the 1^{st} equation with 2 results in 2^{nd} equation.

which means the two line equations represents the same line.

Now, let us find the slope of line, \text { slope }=\frac{-x \text { coefficient }}{y \text { coefficient }}=\frac{-3}{-5}=\frac{3}{5}=\text { positive slope }

So, the line has a positive slope.
