Omar has a gift card for $25 at a clothing store. He wants to buy socks that cost $4 per pair. He also has a coupon for $5 off h

vaieri [72.5K]

Answer:

4x ≤ 30

Step-by-step explanation:

Omar gets 30 dollars off because $25 + $5 = 30. Let x = pairs of socks

We know each pair costs $4, so the cost would be 4x. Omar has to buy as many pairs as he can with only the coupon and gift card. Omar has to spend $30 (the full discount) or less than $30. Therefore, the inequality would be: 4x ≤ 30 or 4x is less than or equal to 30 ($30).

#19 how do you do the work???!

Semenov [28]

Answer:

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

Step-by-step explanation:

move the terms with $x$ to the left side of the equation:

add 3x to both sides

$3x-1+3x=1$

add 3x and 3x

$6x-1=1$

move all term not containing $x$ to the right side:

add 1 to both sides of the equation

$6x=1+1$

$6x=2$

divide each term by 6

$\frac{6x}{6}=\frac{2}{6}$

$x=\frac{2}{6}$

simplify the fraction

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

In a graphing program, graph the following 4 functions in the same coordinate plane.

9966 [12]

See below for the changes when the exponential function is transformed

<h3>How to determine the effect of a</h3>

The exponential functions are given as:

$y = \sqrt x$

$y = 5\sqrt x$

$y = 14\sqrt{x$

$y = -2\sqrt{x$

An exponential function of the above form is represented as:

$y = a\sqrt{x$

See attachment for the graph of the four functions.

<u>When a is large</u>

This is represented by $y = 14\sqrt{x$

In this case, the curve of the base form $y = \sqrt x$ is vertically stretched and it moves closer to the y-axis

<u>When a is small</u>

This is represented by $y = 5\sqrt x$

In this case, the curve of the base form $y = \sqrt x$ is vertically stretched and it moves away from the x-axis

<u>When a is negative</u>

This is represented by $y = -2\sqrt{x$

In this case, the curve of the base form $y = \sqrt x$ is vertically stretched and is reflected across the y-axis.

What would the amount of interest be earned if there is a deposit of $10,000 at 9.5% for 90 days

Bingel [31]

I am working on this in school, this is how we are being taught to do this type of problem:

First, convert the 9.5% to 0.095. Then multiply:

10,000 x 0.095 x 90 = 85,500

So, the answer should be: $85,500 interest.
