Simplify the equation as best you can and then graph it. When you have graphed it, the x-coordinate when y=0 is x.

Alana has a rectangular tapestry on her bedroom wall the tapestry has an area of 48 square feet and a width of 2 yards what is t

Bingel [31]

Answer: 8 feet

Step-by-step explanation:

Ok so first you turn 2 Yards into feet because the answers are all in feet by multiplying by 3/1 so it would look like this 2/1x3/1 which is 6 then you use proportion to get the 6 yards by it self so it would look like this 48/6 6/6 the you would get x= 8 feet to get 8 feet you dividied 48 by 6 hope this helps

Find the area of the compound shape

andrey2020 [161]

This shape is separated into two trapezoids. The equation for the area of a trapezoid is .5(base1 + base2) multiplied by height. Therefore, each half of the compound shape would be equal to .5(12 + 8) * 6 or 10 * 6 = 60. So the area of the total would be 60+60 or 120.

I only need 12 and 17, first good response i will give brainliest please i’m desperate

Mumz [18]

Answer:

$\textsf{12.} \quad y = 6x - 5$

$\textsf{17.} \quad y=-\dfrac{1}{4}x-2$

Step-by-step explanation:

<h3><u>Question 12</u></h3>

Find the slope of the line by substituting two points from the given table into the slope formula.

<u>Define the points</u>:

Let (x₁, y₁) = (2, 7)
Let (x₂, y₂) = (3, 13)

$\implies \textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{13-7}{3-2}=\dfrac{6}{1}=6$

Substitute the found slope and point (2, 7) into the point-slope formula to create an equation of the line:

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

$\implies y-7=6(x-2)$

$\implies y-7=6x-12$

$\implies y=6x-5$

<h3><u>Question 17</u></h3>

Given:

f(4) = 3
f(0) = -2

Therefore, two points on the line are:

(4, -3)
(0, -2)

The y-intercept is the y-value when x = 0.

Therefore, the y-intercept of the line is -2.

$\boxed{\begin{minipage}{6.3 cm}\underline{Slope-intercept form of a linear equation}\\\\$y=mx+b$\\\\where:\\ \phantom{ww}$\bullet$ $m$ is the slope. \\ \phantom{ww}$\bullet$ $b$ is the $y$-intercept.\\\end{minipage}}$

Substitute the y-intercept and the point (4, 3) into the slope-intercept formula and solve for <em>m</em> to find the slope:

$\implies y=mx+b$

$\implies -3=m(4)-2$

$\implies -1=4m$

$\implies m=-\dfrac{1}{4}$

Therefore, the equation of the line is:

$y=-\dfrac{1}{4}x-2$

A box of mixed nuts packs weighs 16 1/2 ounces. Each mixed nuts pack weighs 1 3/8 ounces. How many mixed nuts snack packs are in

vfiekz [6]

12 mixed nuts packs

Explanation:

The box weighs 16 1/2 ounces

1 mixed nut = 1 3/8 ounces

let the number of fruit mixed nut in the box = y

1 mixed nut = 11/8 ounces

y = 33/2 ounces

cross multiply:

$\begin{gathered} 1(\frac{33}{2})\text{ = y(}\frac{\text{11}}{8}) \\ \frac{33}{2}=\frac{11y}{8} \end{gathered}$ $\begin{gathered} 2(11y)\text{ = 33(8)} \\ 22y\text{ = 33(8)} \\ y\text{ = }\frac{33(8)}{22} \end{gathered}$ $\begin{gathered} y\text{ = 264/22} \\ y\text{ = 12 mixed nuts} \end{gathered}$
