Answer:

108

Step-by-step explanation:

So we can break this figure into 2 shapes. A rectangle and a right triangle.

Once we do that, we can solve the area for each shape.

Rectangle: 6 x 3 = 18

For the triangle, we'll need to find the sum of 6 + 6, which would be 12 to find the missing height for the triangle. Then we can find the area.

Triangle: (12 x 15)/2 = 90

We can then add our two answers up to get our final answer.

18 + 90 = 108

Find the image of (3,8) after a reflection over the origin.

Oksana_A [137]

Answer:

(-3, -8) I think

Step-by-step explanation

over the origin mean it would be going diagonally across (0,0). Not directly down (over the x-axis/ across the y-axis), nor to the side (over y-axis/ across the x-axis

What is the solution of the system? Use elimination. 3 (-5x-2y=6) 3x+6y=6

Iteru [2.4K]

Answer:

x = -2 and y = 2

Step-by-step explanation:

The given equations are :

-5x-2y=6 ...(1)

3x+6y=6 ...(2)

Multiply equation (1) by 3. SO,

-15x-6y=18 ...(3)

Adding equation (2) and (3).

3x+6y-15x-6y = 6+18

-12x = 24

x = -2

Put the value of x in equation (1).

-5(-2)-2y=6

10-2y=6

4=2y

y = 2

So, the value of x is -2 and y is 2.

Write the slope-intercept form of the equation of the line described below.

prisoha [69]

The equation of the line is $y=-\frac{2}{5}x-5$

Explanation:

Given that the line passes through the points (-5,-3)

The slope of the line is $m=-\frac{2}{5}$

We need to determine the equation of the line.

Equation of the line:

The equation of the line can be determined using the formula,

$y-y_1=m(x-x_1)$

Let us substitute the points (-5,-3) and the slope $m=-\frac{2}{5}$ in the above formula.

Thus, we have;

$y+3=-\frac{2}{5}(x+5)$

Simplifying, we get;

$y+3=-\frac{2}{5}x-2$

Subtracting 3 from both sides of the equation, we get;

$y=-\frac{2}{5}x-5$

Hence, the equation of the line in slope - intercept form is $y=-\frac{2}{5}x-5$
