Answer:

Step-by-step explanation:

Option C is the only one that's linear because it follows all of the rules for a line to be linear. To check, use the process of elimination:

A). When x is an absolute value, the line will not be linear because an input will have two outputs.

B). x cannot be in the denominator of a fraction for the line to be linear

D). Once again, x cannot be an absolute value.

*Note: I'm assuming in option B, 7x is in the denominator and 1 is in the numerator. If the fraction is simply 1/7 multiplied by x, it is linear along with C.

Katie buys a large pizza for $14.99 and bottles of soda for $1.50 each. If the total cost was $23.99, how many bottles of soda (

Nady [450]

The number of soda bottles Katie bought is 6

The given parameters are:

Large Pizza = $14.99
Soda = $1.50 per bottle
Total cost = $23.99

Assume the number of soda bottle is x.

So, we have:

$Total = Pizza + Soda \times x$

This gives

$23.99 = 14.99 + 1.50\times x$

Subtract 14.99 from both sides of the equations

$9 = 1.50\times x$

Divide both sides of the equations by 1.5

$6=x$

Rewrite the equation as

$x = 6$

Hence, the number of bottles is 6

Determine whether the polygons are similar. If so, identify the correct similarity ratio and the similarity statement. HELP ASAP

Vilka [71]

Answer:

No, the triangles are not similar

Step-by-step explanation:

The (reduced) side length ratios, shortest to longest, are ...

12 : 18 : 20 = 6 : 9 : 10

and

5 : 12 : 13

These are not the same, so the triangles are not similar.

cricket20 [7]

Answer:

Step-by-step explanation:

B. A coordinate plane has an x axis from 0 to 5 in increments of 1 and a y axis from 0 to 5 in increments of 1. Point A (3,1) is plotted 3 units to the right and 1 unit above the origin. Point B (0,3) is plotted 3 units above the origin. Point C (1,3) is plotted 1 unit to the right and 3 units above the origin.

Jakes has $20 to spend on notebooks and pencils the notebooks and pencils. the notebooks cost 3.25 and the pencils cost $.50 wha

Leokris [45]

Hey there. So basically, find out how much the pencils and notebooks cost first.
The notebooks cost = $3.25
The pencils cost = $0.50

Then, think about what you need to figure out in this problem.
Jake has $20. You need to find how many notebooks Jake can buy in maximum after buying 8 pencils.

If Jake buys 8 pencils that costs $0.50 each, he spends $4 on the pencils.

So now, to find out how many notebooks he can buy, do 20 minus 4.
Jake's got $16 left.

If the notebooks cost $3.25 each, we need to find out how many notebooks he can buy by dividing them. So, 16 divided by 3.25 equals 4.923... and so on.

That means, Jake can buy 4 notebooks with his remaining money.
