Answer:

The answer is 69.5

Step-by-step explanation:

First u wanna find the area of the rectangle and since it already gives you the the height and width you want to multiply them together 13×4= 52

meanwhile triangle is 5ft tall and the base is 7ft

using the formula to solve for area of a triangle you would multiply height and base and divide by 2

you should end up with 17.5 then u add that to 52 and get 69.5 ♡ Hope this helps.

A)<br> 2x + y - 12 = 0<br> x + y + 3 = 0

AVprozaik [17]

Answer:

x=15 and y= -18

Step-by-step explanation:

$2x + y - 12 = 0$ Equation 1

$x + y + 3 = 0$ Equation 2

From two given equations, we can find the value of both x and y by finding the value of one variable from any one of the two equations in terms of other variable and putting it to other equation.

Solving equation 1

Finding 'y' in terms of 'x' $2x+y=12\\y=12-2x$ Equation 3

Putting above equation in equation 3 in 2

$x + y + 3 = 0$

$x+12-2x+3=0$

$x=15$

Putting value of 'x' in equation 3 to find the value of 'y'

$y=12-2(15)\\y=12-30\\y= -18$

I believe this is the answer, im so sorry if im wrong

I need help!!!!!!!!!!

Andru [333]

Answer:

Yes

Step-by-step explanation:

The points will be on the same line if they have the same slope. Calculate the slope of each pair. If the slopes are the same, then they lie on the same line.

$m = \frac{y_2-y_1}{x_2-x_1} = \frac{3-2}{1-4} = \frac{1}{-3} = -\frac{1}{3}$

$m = \frac{y_2-y_1}{x_2-x_1} = \frac{4-2}{-2-4} = \frac{2}{-6} = -\frac{1}{3}$

$m = \frac{y_2-y_1}{x_2-x_1} = \frac{4-3}{-2-1} = \frac{1}{-3} = -\frac{1}{3}$

The slope is the same.
