4x + 10 = -26
4x + 10 - 10 = -26 - 10
4x = -36
4x/4 = -36/4
x = -9

6. Find the equation in slope-intercept form for the line that passes through the point (-8, 3) and is parallel
prisoha [69]
<h3><u>The equation in slope-intercept form for the line that passes through the point (-8, 3) and is parallel  to the line -5x + 4y = 8 is:</u></h3>

y = \frac{5}{4}x + 13

<em><u>Solution:</u></em>

Given that,

We have to find the equation in slope-intercept form for the line that passes through the point (-8, 3) and is parallel  to the line -5x + 4y = 8

<em><u>The equation of line in slope intercept form is given as:</u></em>

y = mx + c

Where "m" is the slope of line

From given,

-5x + 4y = 8

Rearrange to slope intercept form

4y = 5x + 8

y = \frac{5x}{4} + \frac{8}{4}\\\\y = \frac{5x}{4} + 2

On comparing the above equation with slope intercept form,

m = \frac{5}{4}

We know that, slopes of parallel lines are equal

Therefore, slope of line parallel  to the line -5x + 4y = 8 is:

m = \frac{5}{4}

\text{Substitute } m = \frac{5}{4}\ and\ (x, y) = (-8, 3) \text{ in eqn 1}

3 = \frac{5}{4} \times -8 + c\\\\3 = -10 + c\\\\c = 13

Substitute c = 13 and m = 5/4 in eqn 1

y = \frac{5}{4}x + 13

Thus the equation of line in slope intercept form is found

Use formulas to find the lateral area and surface area of the given prism. Round your answer to the nearest whole number.
Elanso [62]
Lateral area = Perimeter x height  

Lateral area = (2 + 7 + 7.28) x 31 = 16.28 x 31 = 505 m²

Surface area = 2(1/2 x 2 x 7) + 505  = 519 m²

Answer: Lateral area = 505 m² ; Surface area =  519 m²

Is the answer to this question 4.5
Novay_Z [31]

Answer:

x = 30

Step-by-step explanation:

m<E = [m(arc)AD - m(arc)BC]/2

50 = (130 - x)/2

100 = 130 - x

-x = -30

x = 30
