Answer:

x=4.5 y=0

Step-by-step explanation:

For the x coordinate set y to zero for the y coordinate set x to zero. Example:

0=2x-9

9=2x

4.5=x

pantera1 [17]

Yes, they are proportional because if you increase or decrease either amount they will both change. They will always have the same size. For example if I want to double the flour, I will have to double the milk as well because they have the same ratio.

According to a report by Scarborough Research, the average monthly household cellular phone bill is $73. Suppose local monthly h

Answer:

The probability that a randomly selected monthly cell phone bill is less than $95 is 0.9772

Step-by-step explanation:

The average monthly household cellular phone bill is $73.

$\mu = 73$

Local monthly household cell phone bills are normally distributed with a standard deviation of $11.

$\sigma = 11$

We are supposed to find the probability that a randomly selected monthly cell phone bill is less than $95 i.e.P(x<95)

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

$Z=\frac{95-73}{11}$

Z=2

Refer the z table for p value

So,p value = 0.9772

Hence the probability that a randomly selected monthly cell phone bill is less than $95 is 0.9772

Any of y'all understand how do do any of this?

Luda [366]

Answer:

10.) 12 + 3i

11.) 3 - i

A math conjugate is formed by changing the sign between two terms in a binomial. For instance, the conjugate of x + y is x - y. We can also say that x + y is a conjugate of x - y.

12.) x² - 8x + 17 = 0

Let's solve your equation step-by-step.

x² − 8x + 17 = 0

Step 1: Use quadratic formula with a=1, b=-8, c=17.

x= −b±√b2−4ac / 2a

x= −(−8) ± √(−8)2−4(1)(17) / 2(1)

x= 8 ± √−4 / 2

There are no real solutions.

13.) x²- 8x + 17 = 0

Let's solve your equation step-by-step.

x² − 8x + 17 = 0

Step 1: Use quadratic formula with a=1, b=-8, c=17.

x= −b ± √b2−4ac / 2a

x= −(−8) ± √(−8)2−4(1)(17) / 2(1)

x= 8 ± √−4 / 2

There are no real solutions.

Step-by-step explanation:

To solve a quadratic equation by factoring,

Put all terms on one side of the equal sign, leaving zero on the other side.

Factor.

Set each factor equal to zero.

Solve each of these equations.

Check by inserting your answer in the original equation
