Answer:

3- 6 hours

4- 41 lbs

5- 53 dogs

Step-by-step explanation:

3. 480/24= 20

20= miles per hour

6 hours to travel 120 miles

4. 135/62= 2.18

2.18= cost of tomato per pound

90/2.18= 41.28 lbs or 41 lbs

3. 3/5=32/x

cross multiply

3x=160

divide both sides by 3

x=53.3 or 53

Did I do this right? If not please explain!

Yep! Good job, you did it correctly.
Your y-intercept is equal to the constant of the equation (y-int = -2). Your movement/direction (or rise over run) is equal to the variable. Since your variable is x (which can also be written as 1x) means you move up one and over one (rise over run). This is because 1/1 is equal to 1.

Solve the equation 3/y = 4/5

netineya [11]

Step-by-step explanation:

<u>Step 1: Cross Multiply</u>

$\frac{3}{y} = \frac{4}{5}$

$5(3) = 4(y)$

$15 = 4y$

<u>Step 2: Divide both sides by 4</u>

$15 / 4 = 4y / 4$

$3.75 = y$

Answer: $y = 3.75$

Find the equation of this line. y= [?]x+[?]

DochEvi [55]

Answer:

$y=3x-4$

Step-by-step explanation:

Hi there!

Slope-intercept form: $y=mx+b$ where <em>m</em> is the slope and <em>b</em> is the y-intercept (the value of y when x=0)

<u>1) Determine the slope (</u><u><em>m</em></u><u>)</u>

$m=\displaystyle\frac{y_2-y_1}{x_2-x_1}$ where two points that fall on the line are $(x_1,y_1)$ and $(x_2,y_2)$

On the graph, two points are highlighted for us: (0,-4) and (2,2). Plug these into the formula:

$m=\displaystyle\frac{2-(-4)}{2-0}\\\\m=\displaystyle\frac{2+4}{2}\\\\m=\displaystyle\frac{6}{2}\\\\m=3$

Therefore, the slope of the line is 3. Plug this into $y=mx+b$ :

$y=3x+b$

<u>2) Determine the y-intercept (</u><u><em>b</em></u><u>)</u>

$y=3x+b$

Recall that the y-intercept occurs when x=0. Given the point (0,-4), the y-intercept is therefore -4. Plug this into $y=3x+b$ :

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

I hope this helps!

A intercept of 2 and slope of 1/6

Mekhanik [1.2K]

I’m assuming you want it in slope intercept form so it’s y=1/6x-2
