. This is a problem from Kendra's homework and the sum she found. Though she thought she followed the correct steps to find the

sum, she knows her answer could not be correct. What could be a reason she believes she is incorrect?

What temperature is 15 degrees lower than 7degrees

BabaBlast [244]

15 degrees lower than 7 degrees means that we have to subtract.

So we have 7 degrees and it wants 15 degrees lower, so we would do 7 - 15

And so 7-15 = -8

So 15 degrees lower than 7 degrees would be -8 degrees. :)

What is the value of x? <br>A.39<br>B.41<br>C.26<br>D.17

mojhsa [17]

Answer:

The answer is B.

Step-by-step explanation:

You have to use Pythogorean Theorem, c² = a² + b² where c is the hypotenuse and a,b is the side lengths :

${c}^{2} = {a}^{2} + {b}^{2}$

Let a = 40,

Let b = 9,

${c}^{2} = {40}^{2} + {9}^{2}$

${c}^{2} = 1600 + 81$

${c}^{2} = 1681$

$c = \sqrt{1681}$

$c = 41 \: units$

*Take note, hypotenuse will <u>a</u><u>l</u><u>w</u><u>a</u><u>y</u><u>s</u><u> </u><u>b</u><u>e</u><u> </u><u>t</u><u>h</u><u>e</u><u> </u><u>l</u><u>o</u><u>n</u><u>g</u><u>e</u><u>s</u><u>t</u><u> </u><u>l</u><u>e</u><u>n</u><u>g</u><u>t</u><u>h</u> among the 3 lengths.

*Pythogorean Theorem can only applied in a right-angle triangle.

How does the graph of g(x)=⌈x⌉+7 differ from the graph of f(x)=⌈x⌉?

Lorico [155]

The addition of +7 influences the y values of the graph. Since it is positive, the graph of y=IxI would be moved 7 units upwards.

Hope I helped :)

g(-2) + g(2) = 22

Step-by-step explanation:

For x = -2, g(x) = x^2 - 3x

or

g(-2) = (-2)^2 - 3(-2) = 4 + 6 = 10

For x = 2, g(x) = 12, therefore

g(-2) + g(2) = 10 + 12 = 22
