Answer:
The first: y = -25x + 180Step-by-step explanation:
In every equation b = 170, so
The equation is y =mx + 170
On the line on the graph, for x=2 we have y = 120,so:
120 = m×2 + 170
-50 = 2m
m = 25
Therefore the equation is:
y = -25x + 180

This equation is the total height adding 5 for the top border and 5 for the bottom border. Then multiplying the total height by the width of the border 5, time 2 because there are two sides that are tall Then adding 5 times two widths.

Find the surface area of this cylinder using pie.
Answers
Answer:
Thus, the surface area of a cylinder involving pie is:
[tex]\:\:\:A=36\pi \:[/tex] in²
or
[tex]A\approx 113.1[/tex] in²
Step-by-step explanation:
Given
radius = r = 2 in height = h = 7 inUsing the formula to determine the surface area of a cylinder:
[tex]A=2\pi \:rh+2\pi \:r^2[/tex]
[tex]A=\left(2\times \pi \times \:2\times 7\right)+\left(2\times \pi \times \:2^2\right)\:[/tex]
[tex]\:\:\:A=36\pi \:[/tex] in²

A gift basket has 2 soaps and 5 lotions and costs $20. A second basket has 6 spas and 15 lotions and cost $60. Is it possible to determine the price of the soap?
Answers
A second basket has 6 spas--- I think you mean 6 soaps , so i will work with that
Answer:it is not possible to determine the price of the soap with the information given.
Step-by-step explanation:
Let s0ap be represented as x
and lotion be represented as y
2 soaps and 5 lotions costing $20 gives us equation 1 as
2 x+ 5y= 20-------- equation 1
second basket with 6 soaps and 15 lotions and costing $60 gives us equation 2 as
6x + 15y= 60------equation 2
Step 2 -- Solving
2 x+ 5y= 20-------- equation 1
6x + 15y= 60--------equation 2
BY elimination method, we multiply equation 1 by (3)
2x + 5y= 20 x (3)
6x + 15y=60-------equation 3
Subtraction of equation 3 from equation 2 gives us
6x + 15y=60-------equation 3
-6x + 15y= 60--------equation 2
0x +0y=0 which is no solution
Therefore it is not possible to determine the price of the soap

Give an example of an equation that has no solution equation and explain why it is a no solution equation.
Answers
Answer:
x = x + 7
Step-by-step explanation:
In this equation, it is saying that x is equal to itself plus something else (7). This equation does not make sense at all because x cannot equal to something that is bigger or smaller than itself. If 7 is added to x, like the right-hand side of the equation, it cannot be equal to x from the left-hand side of the equation, so there is no solution to the value of x in this equation.
