Answer:
(1/2) ( 5 - 7x) = 8 - 4x - 6
(1/2) (5 - 7x) = 2 - 4x multipy through by 2
5 - 7x = 4 - 8x add 8x to both sides.......subtract 5 from both sides
x = -1

If f(x)=1/3x+7 and g(x)=-2x-5, find f(g(-7))
Please help.
Answer:
[tex]f(g(-7))=10[/tex]
Step-by-step explanation:
We have the two functions:
[tex]\displaystyle f(x)=\frac{1}{3}x+7\text{ and } g(x)=-2x-5[/tex]
And we want to find:
[tex]f(g(-7))[/tex]
So, we will first find g(-7). We know that:
[tex]g(x)=-2x-5[/tex]
Then by substitution:
[tex]g(-7)=-2(-7)-5[/tex]
Evaluate. Multiply:
[tex]g(-7)=14-5=9[/tex]
Therefore, we can rewrite our expression as:
[tex]f(g(-7))=f(9)[/tex]
Since we know that:
[tex]\displaystyle f(x)=\frac{1}{3}x+7[/tex]
By substitution:
[tex]\displaystyle f(9)=\frac{1}{3}(9)+7[/tex]
Evaluate:
[tex]f(9)=3+7=10[/tex]
Therefore:
[tex]f(g(-7))=10[/tex]
Answer:
[tex]\boxed {\boxed {\sf f(g(-7))= 10}}[/tex]
Step-by-step explanation:
We are asked to find f(g(-7)) given these 2 functions:
[tex]f(x)=\frac{1}{3}x+7[/tex][tex]g(x)= -2x-5[/tex]We must work from the inside out, so first find g(-7).
1. g(-7)
The function for g is:
[tex]g(x)= -2x-5[/tex]
Since we want to find g(-7), plug -7 in for x.
[tex]g(-7)= -2(-7)-5[/tex]
Solve according the PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
Multiply -2 and -7.
[tex]g(-7)=14-5[/tex]
Subtract 5 from 14.
[tex]g(-7)=9[/tex]
2. f(9)
Refer back to the original problem: f(g(-7))
Since we found that g(-7) is 9, we can substitute 9 in: f(9)
The function for f is:
[tex]f(x)= \frac{1}{3} x+7[/tex]
Plug 9 in for x.
[tex]f(9)=\frac{1}{3}(9)+7[/tex]
Solve according to PEMDAS and multiply 1/3 and 9.
[tex]f(9)=3+7[/tex]
Add 3 and 7.
[tex]f(9)=10[/tex]
f(g(-7) is equal to 10
What is the mean average of these five numbers 2, 4, 5, 6, 8
Answer:
5
Step-by-step explanation:
The average (mean) is equal to the sum of all the data values divided by the number of values in the data set.
Mean = Sum / Count
Mean = (2+4+5+6+8) / 5
Mean = 25 / 5
Mean = 5
The average mean of the given data will be "5". A further solution is provided below.
The given data is:
→ [tex]2,4,5,6,8[/tex]
Total number of data value,
= 5
The mean will be:
= [tex]\frac{Sum \ of \ all \ data \ values}{Number \ of \ data \ values}[/tex]
By substituting the given values, we get
= [tex]\frac{2+4+5+6+8}{5}[/tex]
= [tex]\frac{25}{5}[/tex]
= [tex]5[/tex]
Thus the above is the correct answer.

A language arts test is worth 100 points. There is a total of 26 questions. There are spelling word questions thatare worth 2 points each and vocabulary word questions worth 5 points each. How many of each type of questionare there?
Answer:
Spelling word questions = 10
vocabulary word questions = 16
Step-by-step explanation:
Let
Spelling word questions = x
vocabulary word questions = y
Total points = 100
Total questions = 26
x + y = 26 (1)
2x + 5y = 100 (2)
From (1)
x = 26 - y
Substitute x = 26 - y into
2x + 5y = 100
2(26 - y) + 5y = 100
52 - 2y + 5y = 100
- 2y + 5y = 100 - 52
3y = 48
y = 48 / 3
= 16
y = 16
Substitute y = 16 into
x + y = 26
x + 16 = 26
x = 26 - 16
= 10
x = 10
Spelling word questions = 10
vocabulary word questions = 16

44,39 in
Step-by-step explanation:
To find the space diagonal (whatever it's called in English) you begin looking at the bottom of the box. We want to know the diagonal since the diagonal is one of the sides of the other triangle.
To do this we can start by using trigonometry. (SOH-CAH-TOA)
We need to use Sin t. (Since we wanna know the hypothenuse and we have the opposite.)
So...
Sin(40) = 24 in ÷ h
Then we need to actually be able to calculate this, which we will be able to do if we multiply with h on both sides.
hSin(40) = 24 in
Like that. And now we can divide both sides with Sin(40). So we calculate 24 in devided by Sin(40).
h = 24 in ÷ Sin(40) = 37,34 in
Okay so now we now the diagonal, 37,34 in. Now we can use Pythagorean theorem. (2a+2b=2c and c = square root of (2a+2b))
37,34 in^(2) + 24 in^(2) = 1970,28
And now we take the square root of 1970,28.
Which is about 44,39 in.
If you're not familiar with these concepts I suggest you search them up.

Write an equation in point-slope form of the line that passes through the given point and has the given slope. (3, –8); m = –5
Answer:
y+8=-5(x-3)
Step-by-step explanation:
The formula for point-slope form is y-y1=m(x-x1)
The points for (x1, y1) are (3, -8), meaning that 3 is x1 and -8 is y1.
So, start by writing your equation like this: y--8=m(x-3)
For the equation y--8=m(x-3), the y--8 will change to a + sign because two negatives make a positive, right? So, the equation should now look like this: y+8=m(x-3).
We know that the slope (m) is -5. Plug that into the equation to get this: y+8=-5(x-3)
And there you have it!! The equation is now in point-slope form!!
y+8=-5(x-3) is the final answer!!

On the first visit to the veterinarians office chorus kitten weighed 550 g on the second visit the kitten had ganged 350 g on the third visit the kitten had gained 300 g what is the percent increase since the first visit in the kittens wait rounded to the nearest percent
Answer:
[tex]\%Increase = 118\%[/tex]
Step-by-step explanation:
Given
[tex]Initial\ Weight = 550g[/tex]
[tex]First\ Addition = 350g[/tex]
[tex]Second\ Addition = 300g[/tex]
Required
Determine the percentage increment
First, we have to calculate the new weight
[tex]New\ Weight = Initial\ Weight + First\ Addition + Second\ Addition[/tex]
[tex]New\ Weight = 550g + 350g + 300g[/tex]
[tex]New\ Weight = 1200[/tex]
The percentage increment is then calculated as:
[tex]\%Increase = \frac{New\ Weight - Initial\ Weight}{Initial\ Weight} * 100\%[/tex]
[tex]\%Increase = \frac{1200g - 550g}{550g} * 100\%[/tex]
[tex]\%Increase = \frac{650g}{550g} * 100\%[/tex]
[tex]\%Increase = \frac{650}{550} * 100\%[/tex]
[tex]\%Increase = 1.182* 100\%[/tex]
[tex]\%Increase = 118.2\%[/tex]
[tex]\%Increase = 118\%[/tex] -- Approximated
Hence, the percentage increment is approximately 118%

B and c are supplementary. The measure of b is 83 more than the measure of c. Find the measure of each angle
Answer:
C = 48.5° ; B = 131.5°
Step-by-step explanation:
When any two angles are supplementary , it means that their sum is equal to 180°.
It's given in the question that B is 83 more than C . So,
[tex]B = C + 83[/tex]
Also it's given in the question that B & C are supplementary angles.
[tex]=> B + C = 180[/tex]
[tex]=> C + 83 + C = 180[/tex]
[tex]=> 2C = 180 - 83 = 97[/tex]
[tex]=> C = \frac{97}{2} = 48.5[/tex]
Hence,
[tex]B = 83 + 48.5 = 131.5[/tex]
∴ C = 48.5° ; B = 131.5°

Alonzo works as a tutor for $7 an hour and as a waiter for $8 an hour this month he worked a combined total dollar total dollar amount he earned this month
Answer: -1t + 720
Step-by-step explanation:
He worked at both jobs for 90 hours for this month.
He worked t hours as a tutor which means that as a waiter he worked;
= 90 - t hours
The amount earned is therefore;
= 7t + (8 * (90 - t))
= 7t + 720 - 8t
= -1t + 720
