Answer:

a \: 3x - 6 \\ b \: 2y + 8 \\ c \: 8x + 24

Step-by-step explanation:

All we have to do is multiply accordingly. I'll use a for an example.

So for the value before the perentheses we multiply that by all of the values in the perentheses.

3x \:  and \: - 6

So the correct answer would be

3x - 6

You can use the same strategy for all the questions, but I'll just answer those straight away.

Also you may notice I put the variable before the constant in question c because the variable should always go before the constant in expressions and equations.

a bug population doubles every 5 days. If you start with 6 bugs, how many bugs will there be in 35 days
Shtirlitz [24]

Answer:

768 bugs

Step-by-step explanation:

You can rewrite this problem as a function as time where the bug population is f(x), and x is the number of days since the start.

f(x)=6*2^(x/5)

Here, the 6 represents the number of bugs that you start with, the two shows that they double every day, and the /5 shows that they double every 5 days.

By plugging in 35, you get 6*2^7, which is 768.

If u(x)=-2x^2+3 and v(x)=1/x what is the range of (u*v)(x) **the picture should help
nasty-shy [4]
We have that
u(x)=-2 x^{2} +3 \\ \\ v(x)= \frac{1}{x}
u(v(x))=u( \frac{1}{x})=-2( \frac{1}{x} )^{2}  +3 \\ u( \frac{1}{x})= \frac{(3 x^{2} -2)}{ x^{2} }

using a graph tool
see the attached figure

The horizontal asymptote of this function is at <span>y=3</span><span>.
So,
the range of this function is from </span><span>(−∞,3<span>)</span></span>

I will upvote and give brainliest answer
Citrus2011 [14]

Answer:

x = 58 degrees

Step-by-step explanation:

Angle K (which is x) and Angle I are congruent corresponding angles with one another, so if, as an example, Angle I was 10, Angle K would also be 10.

<u><em>All you need to do in this case is add Angle H (56) and Angle A (66) together:</em></u>

56 + 66 = 122

<u><em>Then subtract 122 from 180 (because triangles add up to 180 degrees) to get x:</em></u>

180 - 122 = 58

So, x = 58 degrees.
