The parents both have large teeth, which is dominant. Two dominants make another dominant, so the baby will have large teeth.

A phone company offers two monthly plans. Plan A costs $19 plus an additional $0.11 for each minute of calls. Plan B costs $10 p

Aloiza [94]

Answer:

Part 1) When the amount of calling is 450 minutes the two plans cost the same

Part 2) When the two plans cost the same , the cost is $68.50

Step-by-step explanation:

Part 1) For what amount of calling do the two plans cost the same?

Let

x ---> the number of minutes

y ----> the total cost

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope or unit rate of the linear equation

b is the y-intercept or initial value

In this problem we have

Plan A

The slope is equal to

$m=\$0.11\ per\ minute$

The y-intercept is

$b=\$19$

substitute

$y=0.11x+19$ ----> equation A

Plan B

The slope is equal to

$m=\$0.13\ per\ minute$

The y-intercept is

$b=\$10$

substitute

$y=0.13x+10$ ----> equation B

Equate equation A and equation B

$0.13x+10=0.11x+19$

solve for x

$0.13x-0.11x=19-10\\0.02x=9\\x=450$

therefore

When the amount of calling is 450 minutes the two plans cost the same

Part 2) What is the cost when the two plans cost the same?

substitute the value of x=450 minutes in equation A or equation B and solve for y

$y=0.11(450)+19=68.5$

therefore

When the two plans cost the same , the cost is $68.50

Would the product of two irrational elements always be irrational? Please justify or explain your response

Nastasia [14]

Answer:

Step-by-step explanation:

Simple counterexample: $\sqrt{2}$ which is famously irrational. As the second number let’s take $2\sqrt{2}$ which obviously is also irrational. Their product is $\sqrt{2}\cdot 2\sqrt{2} = 2\cdot 2 = 4$ which is a rational number.

Keep gettin this wrong please help!!!

Maslowich

Answer:

none of the options shown

Step-by-step explanation:

You can add 2x+2 to the inequality and get ...

8 ≥ 2x

4 ≥ x . . . . . divide by 2

This means that there should be a solid circle at x=4, and shading should be to the left of that.

None of the three graphs shown here is appropriate. (We don't see Option 2.)

Attached is the output of a graphing calculator. The solid line at x=4 corresponds to a filled dot on a number line plot.
