Answer:

h(f(x)) = 2x - 11


(the second answer is f(h(x)) = 2x - 4)

Step-by-step explanation:

h(x-7) = 2(x-7) + 3

h(x) = 2x -14 + 3

h(x) = 2x - 11

<u>Answer:</u>

The correct answer option is h(f(x)) = 2x - 11

<u>Step-by-step explanation:</u>

We are given two functions:

f(x) = x-7  and  h(x) = 2x+3

and we supposed to find another function which is h(f(x)).

To find h(f(x)), we need to substitute the value of f(x) in the other function i.e. h(x) to get:

h(f(x)) = h(x-7)

h(f(x))= 2(x-7)+3

h(f(x))=2x-14+3

h(f(x)) 2x-11

Therefore, the correct answer is h(f(x)) = 2x - 11.

Substitute 2m + n =0 and m + 2n =3
melamori03 [73]

There are several ways you can solve this problem if you're trying to solve for m and n. You can substitute, or systems of equations. However, I'm going to use substitution:

2m + n = 0 => n = -2m

We can input that in for the other equation:

m + 2n = 3 now becomes: m + 2(-2m) = 3

Now we can solve:

m + 2(−2m) = 3

m + −4m = 3

(m + −4m) = 3 (Combine Like Terms)

−3m=3

m = -1

Now we can input that value in to solve for n:

We said that n = -2m, and m = -1, so n = -2(-1):Answer:

n = 2

Your final answer is m = -1, and n = 2, which can also be written as (m,n) = (-1,2)

----------------------

However, if you were solving for m+n:

You would add the two equations!:

2m + n = 0

m + 2n = 3

----------

3m + 3n = 3

Now, you can take 3 common:

3(m+n) = 3

m + n = 1

Your final answer for what m + n equals 1!

Determine the solution type for each equation if one solution determine the value for x
sdas [7]

Step-by-step explanation:

Vamos resolver sua equação passo a passo.

10-7c=10+2(3-5c)

Etapa 1: simplifique os dois lados da equação.

10-7c=10+2(3-5c)

10+-7c=10+(2)(3)+(2)(-5c)(Distribuir)

10+-7c=10+6+-10c

-7c+10=(-10c)+(10+6)(Combine os termos semelhantes)

-7c+10=-10c+16

-7c+10=-10c+16

Etapa 2: adicione 10c a ambos os lados.

-7c+10+10c=-10c+16+10c

3c+10=16

Etapa 3: subtraia 10 de ambos os lados.

3c+10-10=16-10

3c=6

Etapa 4: divida os dois lados por três.

3c

3

=

PLS ESTIMATE/ 67% of 8.7
Studentka2010 [4]
67 percent of 8.7

\frac{67}{100}  \times  \frac{x}{8.7}
100x = 67 \times 8.7

100x = 582.9

Divide by 100 on both sides to isolate the x

x = 5.829
Round up (to the nearest tenth place and whole number)

x = 6
x = 5.8
