3x-8<=23 AND -4x+26>=6
bazaltina [42]

Answer:

<u>Step 1:  Solve for x in the first equation</u>

<u />3x-8+8\leq 23+8

3x\leq 31

3x/3\leq 31/3

x\leq \frac{31}{3}

<u>Step 2:  Solve for x in the second equation</u>

<u />-4x + 26-26 \geq 6-26

-4x\geq -20

-4x/-4\geq -20/-4

Since you divide by a negative, you must flip the sign.

x\leq 5

1Find an equation of the line perpendicular to the graph of yx + 5 that has a y-4intercept of (0, -3). Write your equation in sl
lianna [129]

Given data:

The given equation of line is y=x/4+5.

The given y-intercept is (0,c)=(0,-3).

The standard equation of line is,

y=mx+c

Compare the given equation with the above expression.

m=1/4

The expression for the slope which is perpendicular to the given line.

\begin{gathered} m^{\prime}\times m=-1 \\ m^{\prime}(\frac{1}{4})=-1 \\ m^{\prime}=-4 \end{gathered}

The equation of the line which is perpendicular to the given line is,

\begin{gathered} y=m^{\prime}x+c \\ =-4x-3 \end{gathered}

Thus, the line which is perpendicular to the given line is y=-4x-3.

During a sale, every item in a store is 80% of its regular price. If the regular price of a T-shirt is $10, what is its sale pri
kipiarov [429]

Answer:

Step-by-step explanation:

If the regular price of a T-shirt is 10 USD and the store sells off its wares at 80% of its regular price, then the price at which the store would still the aforementioned T-shirt would be 80% of its 10 USD price.

80% of $10 =

0.8 * 10 = $8

This means that the price at which the T-shirt will go for, due to the ongoing sales will be $8.

Also, being asked to find the 10% and 20% of $10 is just as simple

10% of $10 =

0.1 * 10 = $1

20% of $10 =

0.2 * 10 = $2

Therefore, the 10% and 20% of $10 is $1 and $2 respectively.
