Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

y-(a*(x-3)*(x+5))=0

STEP
1
:
Equation at the end of step 1

y - (a • (x - 3) • (x + 5)) = 0
STEP
2
:
Equation at the end of step 2

y - a • (x - 3) • (x + 5) = 0
STEP
3
:
Equation at the end of step 3

y - ax2 - 2ax + 15a = 0
STEP
4
:

Solving a Single Variable Equation:

4.1 Solve y-ax2-2ax+15a = 0

In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.

3241004551 [841]

\large \mathfrak{Solution : }

Slope of the given line is :

  • \dfrac{y_2 - y_1}{x_2 - x_1}

where ,

  • x_2 = 1

  • x_1 =  - 3

  • y_2 =  - 7

  • y_1 =   - 4

let's solve :

  • \dfrac{ - 7 - ( - 4)}{1 - ( - 3)}

  • \dfrac{ - 3}{4}

Slope = -3 / 4

Allushta [10]

Answer:

11 bottles

Step-by-step explanation:

make a proportion because if you're using the same rate proportions can show that it's equal

\frac{7}{90} = \frac{x}{140}

cross multiply

7 *140= 980

divide the answer by 90 to find x

980/90= 10.8

round to 11 because you can't have 10.8 bottles
