X= 35 hope this helpsss

Answer:

<h2>x = 35</h2>

Step-by-step explanation:

\frac{2}{5} x + 15 = x - 6

First multiply through by 5 to eliminate the fraction

That's

5 \times  \frac{2}{5} x + 15(5) = 5x - 30 \\ 2x + 75 = 5x - 30

Next using the subtraction property subtract 5x from both sides

That's

2x - 5x + 75 = 5x - 5x - 30 \\  - 3x + 75 =  - 30

<u>Next subtract 75 from both sides</u>

- 3x + 75 - 75 =  - 30 - 75 \\  -  3x =  - 105

<u>Divide both sides by - 3</u>

\frac{ - 3x}{ - 3}  =  \frac{ - 105}{ - 3}

We have the final answer as

<h3>x = 35</h3>

Hope this helps you

2. Which equation in standard form has a graph that passes through the point (-5,8) and has a
atroni [7]

Answer:

a

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - \frac{1}{5}, thus

y = - \frac{1}{5} x + c ← is the partial equation

To find c substitute (- 5, 8) into the partial equation

8 = 1 + c ⇒ c = 8 - 1 = 7

y = - \frac{1}{5} x + 7 ← in slope- intercept form

Multiply through by 5

5y = - x + 35 ( add x to both sides )

x + 5y = 35 ← in standard form → a

Here are the prices for cans of juice that are the same brand and the same size at different stores. Which store offers the best
lubasha [3.4K]

The best deal is offered by the Store Z

<em><u>Solution:</u></em>

We have to find which store offers the best deal

This is found by calculating the unit rate of each store

Unit rate of each store means price per can .i.e price of 1 can

<h3><u>Store X: 4 cans for $2.48</u></h3>

Therefore, store X sells 4 cans for $ 2.48

Price of 1 can is found by dividing 2.48 by 4

\text{Price of 1 can } = \frac{2.48}{4} = 0.62

Thus unit rate of store X is $ 0.62 per can

<h3><u>Store Y: 5 cans for $3.00</u></h3>

Therefore, store Y sells 5 cans for $ 3.00

Price of 1 can is found by dividing 3.00 by 5

\text{Price of 1 can } = \frac{3}{5} = 0.6

Thus unit rate of store Y is $ 0.6 per can

<h3><u>Store Z: 59 cents per can</u></h3>

1 cents is equal to 0.01 dollar.

59 cents = 0.59 dollar

Thus unit rate of store Z is $ 0.59 per can

Comparing unit rate of store X, Y, Z

0.62 > 0.6 > 0.59

Thus, unit rate of store Z is lower than store Y and store X

Therefore, the best deal is offered by the Store Z

If the two lines y1 = -1/2x +5 and y2 = 2x + 5 were to be graphed, what would their intersection point represent?
grigory [225]

Answer:

D. Their intersection point is the only point where the same input into both functions yields the same output.​

Step-by-step explanation:

The intersection point of 2 graphed lines represents the solution.

At this point, for both lines, there is the same x value (input) and the same y value (output) because both of the lines have that point in common.

So, if those 2 lines were to be graphed, the intersection point would represent the only point with the same input and output for both functions.

D is the correct answer.
