Answer:

g=4.56

Step-by-step explanation:

g+3.42=7.98

Subtract 3.42 from each side

g+3.42-3.42=7.98-3.42

g=4.56

Answer:

4.56

Step-by-step explanation:

Step-by-step explanation:

the domain is the set or range of valid values for x.

the range is the set or range of valid values for y (= f(x)).

if you did not miss anything in your problem statement, then I see a function

y = 2x - 11 + 2

no restrictions are defined.

so, domain and range are both the interval

(-infinity, +infinity).

notice the round brackets, as "infinity" is never a value and cannot be included in an interval.

now, if you missed a division sign and the function looks like

y = 2/x - 11 + 2

then we know, x must never be 0, as a division by 0 is undefined.

so, the domain in that case would be

-infinity < x < 0, 0 < x < +infinity

or short

x <> 0

the range would still be every possible value in

(-infinity, +infinity).

Answer: y=5x-7

[tex]x=200[/tex]

Explanation:

Okay so we can start by substituting in [tex]y[/tex] as we know what it is already:

[tex](\frac{1}{5} )x-(\frac{2}{3} )(15)=30[/tex]

Now at this stage we could use a calculator to figure out what [tex]\frac{2}{3}[/tex] of [tex]15[/tex] are though a bit of mental math is as easy:

[tex](\frac{15}{3} )[/tex] · [tex]2=[/tex] [tex]5[/tex] · [tex]2[/tex]

okay so now we have:

[tex](\frac{1}{5} )x-10=30[/tex]  add 10 to both sides to get rid of the [tex]-10[/tex]

[tex](\frac{1}{5})x=40[/tex] let's get rid of that fraction by multiplying by [tex]5[/tex]

 and there's the solution for x

We can check we got this right by substituting it back into the original equation with the known y:

[tex](\frac{1}{5} )(200)-(\frac{2}{3})(15)=30[/tex]

now,  and we already know what out of is so :

that means

which is ✓

Therefore we know our solution is right.

Answer:

Step-by-step explanation:

g(n) = 2n + 3

h(n) = n − 1

(g * h)(n) = g(h(n))

= g(n − 1)

= 2(n − 1) + 3

= 2n − 2 + 3

= 2n + 1

Answer:

In Functions and Function Notation, we were introduced to the concepts of domain and range. In this section, we will practice determining domains and ranges for specific functions. Keep in mind that, in determining domains and ranges, we need to consider what is physically possible or meaningful in real-world examples, such as tickets sales and year in the horror movie example above. We also need to consider what is mathematically permitted. For example, we cannot include any input value that leads us to take an even root of a negative number if the domain and range consist of real numbers. Or in a function expressed as a formula, we cannot include any input value in the domain that would lead us to divide by 0.

Answer:

Length = 11m and the Breath = 4m

Step-by-step explanation:

L = 3B - 4

p = 32m

2( L + B ) = 32

L + B = 32/2

L + B = 16

(3B - 4) + B = 16

3B - 4 + B = 16

4B - 4 = 16

4B = 16 + 4

4B = 20

B = 20/4 = 5m

B = 5m

L = 3B - 4

L = 3(5) - 4

L = 15 - 4

L = 11m

Answer:

B and E

Step-by-step explanation:

Using the subtraction and division operation, the depth dug by the new drill, and the depth that would have been dug by the old drill are 29.05 feets and 19.37 feets respectively.

The expression for the number of feets dug by the new drill can be calculated thus :

Depth dug = 42.25 feets - 13.2 feets

Depth dug = 29.05 feets

The new drill dug 1.5 times the depth that woukd have been dug by the old drill :

Depth dug by old drill = 29.05 / 1.5

Depth dug by old drill = 19.37 feets

Therefore, the depth dug by old drill will be 19.37 feets

Answer:

To reflect a graph, f(x) over the x-axis, you take -f(x).

So if f(x)=x^2, then -f(x) is -x^2.

Then g(x)=-x^2 is the reflection of your function f(x) over the x-axis.

bcz when she substituted 0 for f she got the same result on both the answers

it does matter what the constant of the first term is as long as the second term remains the same ( the first constant or number is being multiplied by 0 the result will always be 0)
