Solve for y=4x-300 and y=3x+600

1 answer:

7 0

Subsitute 4x-300 for y
4x-300=3x+600
subtract 3x form both isdes
x-300=600
add 300 to both sides
x=900
subsitute 900 for x
y=4(900)-300
y=3600-300
y=3300

x=900
y=3300

Find the slope of the line through the given points.(-4,7) and (-1,-3)Is the slope increasing or decreasing?

galina1969 [7]

• The following formula can be used to find the slope of a line:

$m=\frac{y_2-y_1}{x_2-x_1}$

These points are on the line:

$(x_1,y_1);(x_2,y_2)$

Given the following points:

$\mleft(-4,7\mright);(-1,-3)$

Then, you can set up that:

$\begin{gathered} y_2=-3_{} \\ y_1=7 \\ x_2=-1 \\ x_1=-4 \end{gathered}$

Therefore, substituting values into the formula and evaluating, you get:

$\begin{gathered} m=\frac{-3-7}{-1-(-4)} \\ \\ m=\frac{-10}{-1+4} \\ \\ m=-\frac{10}{3} \end{gathered}$

• As you can notice, the slope is negative. Therefore, you can determine that it is decreasing.

Therefore, the answers are:

• Slope of the line:

$m=-\frac{10}{3}$

• It is decreasing.

Patel is solving 8x2 + 16x + 3 = 0. Which steps could he use to solve the quadratic equation? Check all that apply. 8(x2 + 2x +

BlackZzzverrR [31]

Answer:

Patel can use the first and last steps.

Step-by-step explanation:

The given equation is :

$8x^{2} +16x+3=0$

Patel can use the last step.

$8(x^{2} +2x)+3=0$

Taking 3 to right hand side, we get

$8(x^{2} +2x)=-3$

He can also use this step.....

$8(x^{2} +2x+1)=-3+8$

Upon solving we get,

$8x^{2} +16x+8=-3+8$

=> $8x^{2} +16x=-3+8-8$

=> $8x^{2} +16x=-3$
