Which of the following graphs represents the solution set for 7(4x – 1 ) + 6x > –279? PLEASE HELP

Luda [366]3 years ago

First, solve the inequality:
7(4x - 1 ) + 6x \ \textgreater \  -279\\
28x-7+6x\ \textgreater \ -279\\
34x\ \textgreater \ -272\\
x\ \textgreater \ -8
Since x is <u>greater than</u> -8, you have the arrow point up the graph towards the positive side starting at -8.
Since it's greater than but not equal to -8, the circle is open.

Thus your graph is D.

A department store sells t-shirts for $16.00. Every month that a t-shirt doesn’t sell, the store reduces the selling price by 25
algol13

Answer:

Step-by-step explanation:

A = 25% of 16 ==\frac{25}{100}*8=\frac{1}{4}*8=2

Selling price after reduction = 16 - 2 = $14

B= 25% of 14

=\frac{25}{100}*14=\frac{1}{4}*14=\frac{7}{2}

= 3.5

Selling price = 14 - 3.5 = $10.5

C = 25% of 10.5

=\frac{25}{100}*10.5=\frac{10.5}{4}

= 2.625 = $ 2.63

Selling price = 10.5 - 2.63 = $ 7.87

How do I find the dimensions of three different rectangles with the area of 6 cm^2
myrzilka [38]

The area of a rectangle is (length) times (width).
So you have to find a pair of numbers that multiply to produce 6 .

If you only stick to whole numbers, then I don't think there are three
different ones.  You're going to need one pair that multiply to 6 and
are not both whole numbers.

After I explain how to solve problems, I hate to give answers.  But with
all due respect, I have a feeling that I haven't nudged you enough yet
for you to use my explanation to find the answers on your own.
So here are some answers:

1 and 6
2 and 3

and sets of dimensions that are not both whole numbers, like

0.6 and 10
1.2 and 5
1.25 and 4.8
1.5 and 4
2.4 and 2.5
