There are no solutions to the system of inequalities shown belo

Mathematics

Answer:

False

Step-by-step explanation:

Here's a simple little trick to tell wether a system of inequalities has any solutions or not, just by looking at it:

If the slopes are the same but the y-intercepts are different, the system has no solutions.

If the slopes are different, the system has only one solution.

If the slopes are the same and the y-intercepts are the same, then the system has infinitely many solutions.

By following this logic, since the system given has different slopes, it only has one solution. Therefore your answer is false.

Hope this helps you.

A regular hexagon rotates counterclockwise about its center. It turns through angles greater than 0° and less than or equal to 3

Talja [164]

Answer:

Step-by-step explanation:

A regular hexagon has six side and it is rotated counterclockwise about its center.

rotation is 0° < x ≤ 360

it will map on itself at the multiples of the angle = 360 / 6 = 60°

which are 60°, 120°,180°, 240°, 300° and 360°

the number of different angles = 6

NEED HELP ASAP!! WILL MARK BRAINLIEST! ANSWER IN THIS FORMAT:

liq [111]

Answer:

<h3>Part A: Function type</h3>

Car 1 . Exponential function

<u>The value ratios are constant:</u>

40500/45000 = 36450/4050 = 32805 /36450= 0.9

Car2. Linear function

<u>The value differences are constant:</u>

45000 - 42000 = 42000 - 39000 = 39000 - 36000 = 3000

<h3>Part B: Equations</h3>

f(x) = 45000*0.9ˣ

f(x) = 45000 - 3000x

<h3>Part C: Value after 13 years</h3>

f(13) = 45000*0.9¹³ = $11438

f(13) = 45000 - 3000*13 = $6000

Car 1 will have a greater price

Brianna received an overall IQ score of 117 on the Wechsler Scale. This means that Brianna has scored approximately____________

Tresset [83]

Using the normal distribution, it is found that the correct option is:

D. 1; 100

In a <em>normal distribution</em> with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

It measures how many standard deviations the measure is from the mean.

In this problem:

The mean on the Wechsler Scale is of 100, hence $\mu = 100$ .

The standard deviation is of 17, hence $\sigma = 17$ .

Brianna had an score of 117, hence $X = 117$

Then:

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{117 - 100}{17}$

$Z = 1$

Hence, the option d is correct.
