Answer:

Step-by-step explanation:

When x=0, then you have y+5=0, y=0-5=-5.

So next to 0, enter -5 into the box.

When y=0, then you have 0+5=x/4,

5=x/4,

x=4*5=20.

So next to 0, enter 20 into the box.

I need help! If you could explain that would help alot

Answer:

x = 3. (Refresh if you cannot see the explanation.)

Step-by-step explanation:

$\frac{4x+6}{3} = \frac{x+9}{2}\\\text{Cross multiply.}\\2(4x+6)=3(x+9)\\\text{Distribute.}\\8x+12=3x+27\\\text{Subtract 3x from both sides.}\\5x+12=27\\\text{Subtract 12 from both sides.}\\5x=15\\\text{Divide both sides by 15.}\\x=3\\\\\text{Proof:}\\\\\frac{4x+6}{3}=\frac{x+9}{2}\\\text{Substitute variable.}\\\frac{4(3)+6}{3}=\frac{3+9}{2}\\\text{Simplify numerators.}\\\frac{18}{3}=\frac{12}{2}\\\text{Divide both sides.}\\6=6$

Subtract, write your answer as a mixed number in simplest form 6 1/6 - 3 1/4

krok68 [10]

The answer is 35/12 and simplify that and u get 2 11/12.

To show my work apparently since the mods wont stop deleting my answers, here.

I first found a common denominator and use it to rewrite each fraction. Then I, subtracted the whole numbers and fractions separately.

You construct a 95% confidence interval for a population mean using a random sample. the confidence interval is 24.9less thanmu

svet-max [94.6K]

No. It is not that the probability that $\mu$ is in the interval is 0.95 rather we are 95% confident that the true mean of the population will be in the stated interval.

Confidence interval does not specify the probability of the occurrence of a population mean in an interval, rather it specifies the level of confidence on the interval of occurrence of the population mean.

The tires on your bicycle have a diameter of 9 inches. How many rotations does each tire make when you travel 300 feet? Round yo

Olegator [25]

9*3.14 = 28.26

(This solves for circumference)

300/28.26 = 10.6157

(This solves for rotations)

About 11 rotations.
