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.

$x\leq 5$

hello :

the graph passes by ( -4; 7/128) : f(-4) = 7/128

a/ (-4)^4 = 7/128

a / 256 = 7/128

a/2 = 7

a = 14

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.
