Answer:

Choice C 42 in^2

Step-by-step explanation:

Area of a triangle= 1/2(b)(h)

= 1/2(3)(6)

= 9

Since there is two triangles we can do:

9(2) = 18

Area of a rectangle = (b)(h)

= (4)(6)

= 24

24+18 = 42 in^2

Solve: negative 1 over 2 x + 1 = −x + 8 (5 points)
Naya [18.7K]
It is 14 because if you have -1/2x + 1 = -x + 8 you would combine the multiplied terms into a single fraction then subtract the one from both sides simplify till you get -x/2 = -x + 7 then you will add like terms so the x’s then you multiply all terms by two like 2(-x/2)= 2•7 then you can get 14.

Which line has the same slope as the lone passing through (-4,-1) and (-1,-7)
Julli [10]

Answer:

1) 6x+3y=5    

Step-by-step explanation:

1) First, find the slope of the line passing through (-4, -1) and (-1, -7). Use the slope formula m = \frac{y_2-y_1}{x_2-x_1}. Substitute the x and y values of the two points into the formula and solve:

m = \frac{(-7)-(-1)}{(-1)-(-4)} \\m = \frac{-7+1}{-1+4} \\m = \frac{-6}{3} \\m = -2

So, the slope is -2.

2) Now, identify the slopes of the lines in the options. We already know the slope of y = -\frac{1}{2} x-7  is -\frac{1}{2} since it is in slope-intercept form. y = -2 must have a slope of 0 since it's horizontal, and all equations with the format of y = a number are horizontal.

To find the slope of 6x + 3y = 5, isolate y to put the equations into slope-intercept form (y = mx + b format), and whatever the coefficient of the x-term is will be the slope.

6x + 3y = 5\\3y = -6x+5\\y = -2x + \frac{5}{3}.

So, the slope of the first option is -2. It matches the slope we calculated in the first step, so that must be the answer.
