Mathematics

1 answer:

Naddik [55]2 years ago

7 0

Answer:

-3 < x ≤ -1

Step-by-step explanation:

-8 < 5x + 7 ≤ 2

First, subtract 7 from all sides of the inequality:

-8 - 7 < 5x + 7 - 7 ≤ 2 - 7

-15 < 5x < -5

Divide all sides by 5 to isolate x:

-15 ÷ 5 < 5x ÷ 5 ≤ -5 ÷4

-3 < x ≤ -1

Hope this helps!

Someone help with this question ?????? Hi

8090 [49]

ANSWER

The second statement is the contrapositive of the first.

EXPLANATION

If we have the conditional statement,

$x\Rightarrow \: y$

Then the converse of this statement is
$y\Rightarrow \: x$

The inverse of this statement is
$\neg \: x\Rightarrow \neg \: y$

and the contrapositive of this statement is
$\neg \: y\Rightarrow \neg \: x$

The correct answer is C.

To hire a bicycle it costs $6 for each day plus a fixed charge of $15

shusha [124]

Answer:

4 days

Step-by-step explanation:

1) Derive a formula.

Let b = bicycle

Let x = the number of days

A set up equation: b = 6x + 15

2) If she pays 39 to hire a bicycle, substitute 39 into b, then solve for x.

39 = 6x + 15

39 - 15 = 6x

24 = 6x

24/6 = x

4 = x

x = 4

Since x is the number of days, she hired the bicycle for 4 days.
