Answer:

X

Step-by-step explanation:

Show -3.5 not -4.5

The correct answer is B) X is not placed correctly.

Since fractions are basically like division, we can divide the numerator (top number) by the denominator (bottom number). By doing this you will find out that X is not in the correct spot and it should not be there on the graph.

Hope this helps!

In the diagram, \angle ABD∠ A B D and \angle BDC∠ B D C are supplementary, the measure of \angle EDF=9x^\circ∠ E D F = 9 x ∘, and the measure of \angle ABD\:=\:\left(2x+105\right)^\circ.∠ A B D = ( 2 x + 105 ) ∘ .

Based on this information, which equation can be used to find the value of x?

A package of sliced homemade bread with 11 slices costs $3.97. How much would a package with 18 slices cost at the same price per slice?

Answers

Answer:

$6.48

Step-by-step explanation:

3.97/11 = .36

.36*18= 6.48

The cost price of a package of 18 slices of homemade bread at the 0.3609 per slice is $6.496.

What is ratio?

Ratio basically compares quantities, that means it shows the value of one quantity with respect to the other quantity.

If a and b are two values, their ratio will be a:b,

Given that,

The cost price of 11 slices = $3.97

To find cost price of 18 slices,

First, find the cost price of 1 slice.

Use ratio property,

cost of 11 slices = 3.97

cost of 1 slices = 3.97/11 = 0.3609

Cost of 18 slices = 0.3609 x 18  = 6.496

The cost of 18 slices is $6.496.

x is the expoint, and you have to multiply the expoint by the base number

4 x 4= 16

the reason why you are multiplig 4 by 4 is because the expoint told you how many times you needed to multiply the base number by

4^(2)= 16 + 10 will equal 26

Vivian is at a fair in Coachella Valley, California. Much of the valley lies below sea level. Vivian has brought along an altimeter to measure her elevation at different places in the valley. Vivian’s first ride was on the Ferris wheel. When she sat on the wheel at its lowest point, her altimeter read -9.6 feet. When she reached the top of the wheel, her altimeter read 12.3 feet.

Is the change in Vivian's elevation from the bottom of the Ferris wheel to the top a positive number or a negative number? Why?

Answers

It is a positive because 12.3 is going to overflow -9.6 therefore you answer is going to positive.

Answer: Its a positive number

Step-by-step explanation:

If you look it says she is at sea level which is 0 and she is going up 12.3 feet so its positive.

( determine the values of the unknowns that make the function continuous everywhere?)​

Answers

Answer:

a = 4

b=-12

Step-by-step explanation:

For h(x) to be continuous, h(2) = -4 and h(5) = 8. a represents the slope of the line, which can be found using [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]=[tex]\frac{8-(-4)}{5-2} =4[/tex], so a = 4.

Now we can use our known values and either point to solve for b.

Using h(2) = -4:

[tex]-4 = 4(2)+b\\b=-12[/tex]

So, a = 4 and b = -12.

a=4
b=-12 hope it will help you
