Pepsi [2]

Answer:

She sold 39 tall candies and 52 short candies

Step-by-step explanation:

x is all the tall candies

y is all the short candies

x+y=91

8x+5y=572

Use the method of Substitution to find out both x and y.

x=91-y

8(91-y)+5y=572

728-8y+5y=572

728-3y=572

3y=156

y=52

x+52=91

x=39

Write the equation of the line in point-slope form that has slope 3 and passes through (2, -5)

Fynjy0 [20]

Answer:

y = 3x - 11

Step-by-step explanation:

Step 1:

y = mx + b Slope Intercept Form

Step 2:

y = 3x + b Input Slope

Step 3:

- 5 = 3 ( 2 ) + b Input x and y values

Step 4:

- 5 = 6 + b Multiply

Step 5:

- 11 = b Subtract 6 on both sides

Answer:

y = 3x - 11

Hope This Helps :)

<h2>Writing an Equation of a Line in Slope-Intercept Form</h2><h3>Answer:</h3>

$y = [ -2 ] x + [ 1 ]\\$

<h3>Step-by-step explanation:</h3>

<em>Please refer to my answer from this Question to know more about Slope-Intercept Form: <u>brainly.com/question/24599351</u></em>

We must first find the slope.

<em>Please refer to my Answer from this Questions to know more about Slopes of a Line:</em>

<em><u>brainly.com/question/24640665</u></em>
<em><u>brainly.com/question/24638053</u></em>

We can see the marked points, $(0,1)$ and $(4, -7)$ , are on the line.

Solving for the slope:

$m = \frac{y_2 -y_1}{x_2 -x_1} \\ m = \frac{-7 -1}{4 -0} \\ m = \frac{-8}{4} \\ m = -2$

Now we can now solve for the $y$ -intercept.

<em>Please refer to the second paragraph of my Answer from this Question to know more about y-intercepts: <u>brainly.com/question/24606058</u></em>

We can see that the line intersected the $y$ -axis at $(0,1)$ so $b = 1$ .
