Identify the area of the figure rounded to the nearest tenth. HELP?!! I don't understand!! Please help and show your work!!

Alex73 [517]

Answer:

$67.5\ cm^{2}$

Step-by-step explanation:

we know that

The area of the figure is equal to the area of rectangle (figure 1) plus the area of trapezoid (figure 2)

see the attached figure to better understand the problem

The area of the rectangle is

$A=15*3=45\ cm^{2}$

The area of the trapezoid is

$A=\frac{1}{2}[(15-9)+3)](8-3)$

$A=\frac{1}{2}[6+3)](5)=22.5\ cm^{2}$

The area of the figure is

$45\ cm^{2}+22.5\ cm^{2}=67.5\ cm^{2}$

A. 5° B. 35° C. 31° D. 7°

MrRissso [65]

Answer:

(2x +30) and (3x -5) (they're opposite to eachother, so they're equal)

2x + 30 = 3x - 5 (set them equal to eachother, then subtract 3x from both side)

-1x = -35 (divide both sides by -1 to isolate x)

x = 35 or B (this is your answer)

Graph the line with slope -3 passing through the point (3,-4)

Vinvika [58]

Given: $\textsf{Slope = -3, Passes through (3, -4)}$

Find: $\textsf{Equation in slope-intercept form}$

Solution: The first step that we need to take is to plug the given values into the point-slope formula which would help us out since we have both the slope and a point. Using that we would then distribute on the right side of the expression and then subtract 4 from both sides which would isolate y.

Plug in the values

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

$y - (-4) = -3(x - 3)$

Distribute

$y + 4 = (-3 * x) + (-3 * - 3)$

$y + 4 = -3x + 9$

Subtract 4 from both sides

$y + 4 - 4 = -3x + 9 - 4$

$y = -3x + 9 - 4$

$y = -3x + 5$

Therefore, after plugging in the values and completing the rest of the steps we were able to determine that equation of the data provided would be $y = -3x + 5$ .
