The store manager decided to decrease price of ice cream store sells by 10% for the month of July. The amount of ice-cream sold

in July increased by 24% comparing to June. Did the store proceedings (money that the store obtained from ice cream sales) increase or decrease in July? By how many percent?

Answer:

For example:

Price of ice cream in june was 10$ and amount of ice cream sold is 100. Store earned 10$ 100=1000$

Price of ice cream in july has been decreased by 10%. Price of ice cream is now 9$. The amoun of ice cream sold in july increased by 24% compering to june. So amount of sold ice cream in july is 124. Store earned 9$*124=1116$.

Store's proceedings increased in July by 11.6%.

Which equation represents a line that passes through (-2, 4) and has a slope of 1/2?

jok3333 [9.3K]

Answer:

$\large\boxed{y-4=\dfrac{1}{2}(x+2)\text{- point-slope form}}\\\boxed{y=\dfrac{1}{2}x+5\text{- slope-intercept form}}$

Step-by-step explanation:

The point-slope form of an equation of a line:

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

m - slope

We have the slope $m=\dfrac{1}{2}$ and the point $(-2, 4)$ .

Substitute:

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

$y-4=\dfrac{1}{2}(x+2)$ - point-slope form

Convert to the slope-intercept form (y = mx + b):

$y-4=\dfrac{1}{2}(x+2)$ <em> use the distributive property</em>

$y-4=\dfrac{1}{2}x+1$ <em>add 4 to both sides</em>

$y=\dfrac{1}{2}x+5$ - slope-intercept form

Solve for y PLEASE HELPPPPPPP!!!

natima [27]

Answer:

y = (d - 5x)/5, as you selected.

Step-by-step explanation:

$d=5x+5y\\[Subtract 5x from both sides.]d-5x=5y\\[Divide both sides by 5. Keep the d and the -5x together.]\frac{d-5x}{5}=y$

Which system below has no solution?

My name is Ann [436]

Answer:

None of these options has "no solution"

Step-by-step explanation:

we will verify each options

(1)

y = 4x and y = 2x - 3

we can set them equal and solve for x

$4x=2x-3$

$2x=-3$

$x=-\frac{3}{2}$

Since, solutions exists

so, this is FALSE

(2)

y = -4x and y = 2x - 3

we can set them equal and solve for x

$-4x=2x-3$

$-6x=-3$

$x=\frac{1}{2}$

Since, solutions exists

so, this is FALSE

(3)

y = 4x and y = 2x+ 3

we can set them equal and solve for x

$4x=2x+3$

$2x=3$

$x=\frac{3}{2}$

Since, solutions exists

so, this is FALSE

(4)

y = -4-x and y = 2x - 3

we can set them equal and solve for x

$-4-x=2x-3$

$-3x=1$

$x=-\frac{1}{3}$

Since, solutions exists

so, this is FALSE

So, No system of equations have no solution

Jimmy walked from his house, to school, then to the store, and finally back home. The distance from the school to the store is 1

natka813 [3]

The distance from Jimmy's house to the school is 400 meters.

Step-by-step explanation:

Step 1; Assume that the distance between Jimmy's house and his school is x meters. So from the given data, we can form these

Distance from his house to the school = x,

Distance from his school to the store = Distance from his house to the school + 100 = x + 100,

Distance from the store to his house = Distance from his house to the school + 175 = x +175.

Step 2; It is given that the total distance Jimmy walked was 1,475 meters. Jimmy walked a total of three trips so,

x + x + 100 + x + 175 = 1,475,

3x + 275 = 1,475,

3x = 1,475 - 275 = 1,200,

x = 400.

So distance from Jimmy's house to school = 400 meters,

Distance from his school to the store = 400 + 100 = 500 meters,

Distance from the store to his house = 400 + 175 = 575 meters.
