Answer:

$y = -2x +3\\\rule{150}{0.5}\\\text{Slope: -2}\\\text{Y-Intercept: 3}$

Step-by-step explanation:

We would have to convert the standard equation into slope-intercept form.

======================================

<h3><u>Converting the equation into Slope-Intercept Form:</u></h3>

<u /> $8x + 4y = 12\\\rule{150}{0.5}\\8x - 8x + 4y = 12-8x\\\\4y = 12-8x\\\\4y = -8x + 12 \leftarrow \text{I switched the order on the right side.}\\\\\frac{4y=-8x+12}{4}\\\\\boxed{y = -2x + 3}$

======================================

<h3><u>Identifying the Slope and Y-Intercept:</u></h3>

<em>General slope-intercept form is: </em>

<em></em> $y=mx + b\\\rule{150}{0.5}\\\text{m - Slope}\\\text{b - Y-Intercept}$

<u />

In the equation $y = -2x + 3$ , '-2' would be the slope since it is in 'm's place, and '3' would be the y-intercept since it's in 'b's place.

<em>Therefore:</em>

<em></em> $\text{In } y=-2x+3\text{...}\\\rule{150}{0.5}\\\text{Slope: -2}\\\text{Y-Intercept: 3}$ <em></em>

======================================

<em>Hope this helps!</em>

Find x<br><br><br>A) 12<br><br>B) 13 <br><br>C) 11<br><br>D) 10

Soloha48 [4]

We know that the sum of arc ND and arc ML divided by 2 is equivalent to 6x + 23.

Thus, we can form an equation:

6x + 23 = (11x + 8 + 3x + 14)/2

Simplify:

6x + 23 = (14x + 22)/2

Simply again:

6x + 23 = 7x + 11

Subtract 6x from both sides:

23 = x + 11

Subtract 11 from both sides

x = 12

Option A, or x = 12

How much cardboard is needed to make the tissue box above? Square inches 8 3 3

Katen [24]

The amount of cardboard needed to make a cuboid box of dimensions 8 inch, 3 inches and 3 inches is 114 sq. inches.

<h3>What is the surface area of cuboid?</h3>

Let the three dimensions(height, length, width) be x, y,z units respectively.

The surface area of the cuboid is given by

$S = 2(a\times b + b\times c + c\times a)$

For this case, tissue box is almost cuboid shaped.

Also, its dimensions are given being 8 inches, 3 inches and 3 inches.

Suppose we measure the amount of cardboard needed in terms of area, then, the amount of cardboard needed to make that box(without any whole, full cuboid) is equal to the area of its surface(either outer or inner if we assume 0 inches thickness of cardboard),

Thus, we get:

Amount of cardboard needed = surface area of cuboid box with dimensions 8 by 3 by 3 (in inches)

= $2(8 \times 3 + 3 \times 3 + 3 \times 8) = 114 \: \rm in^2$

Thus, the amount of cardboard needed to make a cuboid box of dimensions 8 inch, 3 inches and 3 inches is 114 sq. inches.

Please help i'm stuck :,)

Ksju [112]

Answer:

14 minutes below or 6 minutes above

Step-by-step explanation:

Let's say Sophia's time was 10 minutes WORSE

4 minutes below average- 10 minutes= 14 minutes below average

Let's say Sophia's time was ten minutes BETTER

4 minutes below average + 10 minutes= 6 minutes above average.

Hope this helps!
