5(2i+4) - i = 38
distributive property
9514 1404 393
Answer:
i = 2
Step-by-step explanation:
The outside factor multiplies each term in parentheses.
5(2i +4) -i = 38
10i +20 -i = 38 . . . . eliminate parentheses
9i +20 = 38 . . . . . . collect terms
9i = 18 . . . . . . . . . . subtract 20
i = 2 . . . . . . . . . . . . divide by 9

Three functions are given below: f(x), g(x), and h(x). Find the axis of symmetry for each function, and rank the functions based on their axis of symmetry (from smallest to largest). Show your work for OR explain how you found each axis of symmetry.
f(x) = -4(x − 8)2 + 3
g(x) = 2x2 − 16x + 15
h(x)= the picture
Answer:
Step-by-step explanation:
f(x)=-4(x-2)²+3
put x-2=0
axis of symmetry is x=2
g(x)=-2(x²+8x)+15
=-2(x²+8x+4²-4²)+15
=-2(x+4)²+32+15
=-2(x+4)²+47
put x+4=0
axis of symmetry is x=-4
h(x) is minimum at x=1
axis of symmetry is x=1

. Given that r satisfies the inequality 20.x > 33,
find the smallest value of x if .r is a prime number.
Answer: x = 2.
Step-by-step explanation:
By an online search, i found that the question is:
"Given that x satisfies the inequality 20*x > 33, find the smallest value of x if x is a prime number."
To find the smallest value of x we need to input different possible values of x (where we have the condition that x must be a prime number) and see which one is the first one that makes the inequality true.
The prime numbers are:
2, 3, 5, ....
Let's start with the smaller one, x = 2
So we input it in the inequality and get:
20*2 > 33
40 > 33
this is true.
Then we can have x = 2, which is the smaller prime number that satisfies the inequality.

-8x is less than or equal to 32
What is the inequalities that are possible.
Answer:
We conclude that:
[tex]-8x\le \:32\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-4\:\\ \:\mathrm{Interval\:Notation:}&\:[-4,\:\infty \:)\end{bmatrix}[/tex]
The solution graph on the number line is also attached.
Step-by-step explanation:
Given the inequality
[tex]-8x\:\le 32[/tex]
Solving the inequality
[tex]-8x\:\le 32[/tex]
Multiply both sides by -1 (reverse the inequality)
[tex]\left(-8x\right)\left(-1\right)\ge \:32\left(-1\right)[/tex]
Simplify
[tex]8x\ge \:-32[/tex]
Divide both sides by 8
[tex]\frac{8x}{8}\ge \frac{-32}{8}[/tex]
Simplify
[tex]x\ge \:-4[/tex]
Therefore, we conclude that:
[tex]-8x\le \:32\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-4\:\\ \:\mathrm{Interval\:Notation:}&\:[-4,\:\infty \:)\end{bmatrix}[/tex]
The solution graph on the number line is also attached.

In a company, 65% of the workers are women. If 1820 people work for the company who are men, how many workers are there in all?
Answer:
women=x=65%
so men=100-65=35%=1820
let total workers be y
atq....y×35/100=1820=y=5200workers
Juanita has saved 35% of the money for a bike. She has saved $63 dollars. How much does the bike cost?
Answer:
The total cost of the bike is $180.
Step-by-step explanation:
Given that Juanita has saved 35% of the money for a bike.
Let the total cost of the bike = x
As she has saved $63 dollars which represents the 35% of the money for a bike.
In other words, 35% of the total cost is $63 dollars.
As the total cost = x
Thus,
35% of x = 63
[tex]\frac{35}{100}x=63[/tex]
Multiply both sides by 20
[tex]20\times \frac{35}{100}x=63\times \:20[/tex]
simplify
[tex]7x=1260[/tex]
Divide both sides by 7
[tex]\frac{7x}{7}=\frac{1260}{7}[/tex]
Simplify
[tex]x=180[/tex] $
Thus, the total cost of the bike is $180.
For a large order, Mr. Magoo made 3/8 kg of fudge in his bakery. He then got 1/6 kg from his sister’s bakery. If he needs a total of 1 1/2 kg, how much more fudge does he need to make? Put your answer in fraction form. Example: Mr. Magoo needs to make #/# more fudge.
(PS: Please show your work)
Answer:
Amount fudge he needs = 23/24 kg
Step-by-step explanation:
Given:
Total fudge wants = 1[tex]\frac{1}{2}[/tex] = 3/2 kg
His sister gave = 1/6 kg
He make = 3/8 kg
Find:
Amount fudge he needs
Computation:
Amount fudge he needs = Total fudge wants - His sister gave - He make
Amount fudge he needs = 3/2 - 1/6 - 3/8
Amount fudge he needs = 23/24 kg
the length of the rectangle is 7 cm less than 4 times its width the area is 15 square cm
Answer:
I guess the answer is 4.4 cm or 22/5 cm
Step-by-step explanation:
AREA= 15cm^2
Let the Breadth be x
Length= 4x-7
Area = l×b
15 = 4x-7×x
15+7=4x+x
22=5x
22÷5=x
4.4=x
Therefore, Breadth= 4.4cm Length= 10.6cm

14x + y | Combine like-terms (subtract the y's)
one number is 5 times another number.their sum is 90.find the numbers.
Step-by-step explanation:
let both unknowns be x and y
x = 5y. ......(1)
x + y = 90. ......(2)
sub eqn (1) into eqn (2)
5y + y = 90
6y = 90
y = 90/6
= 15
sub y = 15 to eqn (1)
x = 5y
x = 5 × 15
× = 75
Bradley's Copiers sells and repairs photocopy machines. The manager needs weekly forecasts of service calls so that he can schedule service personnel. Use the actual demand in the first period for the forecast for the first week so error measurement begins in the second week. The manager uses exponential smoothing with a = 0.1. Forecast the number of calls for week 6, which is next week.
Week Actual Service Calls 2

The forecast for week 6 is ________ service calls.
Answer:
28.86
Step-by-step explanation:
According to the scenario, computation of given data are as follows,
Exponential smoothing a = 0.1
we can calculate forecast for each week by using following formula,
Forecast for week = Forecast of last week + a × ( actual calls of last week - forecast of last week)
By using this method, forecast for all week are as follows
