13x+8+8x=-9x-22
please help i’m so confused
Answer:
-1
Step-by-step explanation:
-isolate everything with x on one side and without x on the other side
-remember if you pass the equal sign change the sign of that term
13x+8x+9x = -22-8
-combine like terms
30x = -30
-divide both sides by 30
x= -1
Answer:
x = -1
Step-by-step explanation:
simplfy to 21x + 8 = -9x -22
add 9x to get 30x + 8 = -22
then subtract 8 to get 30x =-30
divide by 30 and you get x = -1

Apples: $(2x) per pound
Grapes: $(6x - 5) per pound
Oranges: $(x + 2) per pound
A shopper purchases one pound each of
apples, grapes, and oranges and spends
$10.50. How much is spent on each type
of fruit?
Answer:
x= 1.5 $
Step-by-step explanation:
Hi there,
This is a tough question. Let us find out how to tackle it.
From the problem, we see that we 'll have to find x to figure out how much each type is. The only real number of money we get is 10.50$ - the amount the shopper spent. Let's divide this money into respective parts:
He bought 1 pound of apple => the cost of all the apple he bought is 1 ( pound) × (2x) ($ per pound) = 2x $
Do the same with Grapes and Oranges, we can easily see that he spent 6x-5 $ on grapes, x+2 $ on oranges.
The total amount he spent 10.50$ is now equal to (2x) + (6x-5) + (x+2).
Next we can change this equation, just so we find x easier:
10.50$ = (2x) + (6x-5) + (x+2)
10.50$ = 2x + 6x + x + 2 - 5
10.50$= 9x - 3
13.50$= 9x
x= 1.50 $
Thus, we can now calculate the price of each type. Apples are 3$ per pound, grapes are 4$ per pound, oranges are 3.50$ per pound.
HOPE YOU'LL LEARM WITH JOY AND GOOD GRADE
Answer:
Shopper spend on Apples $3 , on Grapes $4 and on Oranges $3.5
Step-by-step explanation:
We are given:
Apples: $(2x) per pound
Grapes: $(6x - 5) per pound
Oranges: $(x + 2) per pound
A shopper purchases one pound each of apples, grapes, and oranges and spends $10.50.
It can be written as: [tex]2x+6x-5+x+2=10.50[/tex]
We need to find how much the shopper spend on each fruit.
Solution:
Now, we need to find value of x by solving equation
[tex]2x+6x-5+x+2=10.50[/tex]
Solving:
[tex]2x+6x+x+2-5=10.50\\9x-3=10.50\\9x=10.50+3\\9x=13.5\\x=\frac{13.5}{9}\\x=1.5[/tex]
The value of x is: x=1.5
Now finding cost of one pound each fruit by putting x=1.5
Apples: $(2x) per pound
$2x= 2(1.5) = $3
Grapes: $(6x - 5) per pound
$(6x-5) = (6(1.5)-5)= $4
Oranges: $(x + 2) per pound
$(x+2)=(1.5+2)=$3.5
So, shopper spend on apples $3, on Grapes $4 and on Oranges $3.5.

Given expression is (3x²y⁴)²
We can rewrite the given expression as,
(3x²y⁴)² = (3)²(x²)²(y⁴)² [Every term of the the expression will be squared]

3 Cos(2x) = 5 Sin(x) - 1
Given :
Solve [0, 2π)
3cos(2x) = 5sin(x) - 1
To Find :
The value of x in range [0,2π).
Solution :
We know, cos(2x) = 1 - sin²x .
3( 1 - 2sin²x ) = 5sinx - 1
3 - 6sin²x = 5sinx - 1
6sin²x + 5sinx - 4 = 0
6sin²x + 8sinx - 3sinx - 4 = 0
2sinx( 3sinx + 4 ) - 1( 3sinx + 4) = 0
sin x = 1/2 and sin x = -4/3 .
Since, sin x ≤ 1.
So, sin x = 1/2 .
x = π/6 .
Therefore, value of x is π/6.
Hence, this is the required solution.

7. What are the x-intercepts of the graph of y = (3x +8)(5x - 3)(x - 1)?
Answer:
y = 15x^3 + 16x^2 - 55x + 24
Step-by-step explanation:
y = (3x +8)(5x - 3)(x - 1)
y = (15x^2 - 9x + 40x -24) * (x - 1)
y = (15x^2 + 31x - 24) * (x-1)
y = 15x^3 - 15x^2 + 31x^2 - 31x - 24x + 24
The x-intercepts of a graph are the points where the graph crosses the x-axis.
The x-intercepts are: [tex]\mathbf{x = ,-\frac83, \frac 35\ and\ 1}[/tex]
The function is given as:
[tex]\mathbf{y = (3x + 8)(5x - 3)(x - 1)}[/tex]
First, we plot the graph of [tex]\mathbf{y = (3x + 8)(5x - 3)(x - 1)}[/tex]
See attachment for the graph
Next, write out the x-values when the graph crosses the x-axis.
From the graph, we have:
[tex]\mathbf{x = -\frac 83}[/tex]
[tex]\mathbf{x = \frac 35}[/tex]
[tex]\mathbf{x = 1}[/tex]
Hence, the x-intercepts are: [tex]\mathbf{x = ,-\frac83, \frac 35\ and\ 1}[/tex]

Anna and Jason have summer jobs stuffing envelopes for two different companies. Anna earns $14 for every 400 envelopes she finishes. Jason earns $9 for every 300 envelopes he finishes. I need someone to solve this but represent it on a table instead of a graph.
Answer:
Q1: 20,000 envelopes
Q2: Savings = $700
Step-by-step explanation:
Let the number of envelopes stuffed by each be "x"
We can create 2 equations, each for Anna and Jason, equate them and find our answer.
For Anna:
$14 for 400, so
14/400 = $0.035 PER ENVELOPE
Savings for Anna is 0.035x
For Jason:
Already has 100 (fixed)
Gets $9 for 300 envelopes, so
9/300 = $0.03 PER ENVELOPE
Savings for Jason is 100 + 0.03x
We equate and solve for x:
So, For both their savings to be equal, they need to stuff 20,000 envelopes
Their savings would be:
0.035x
or 100 + 0.03x
We can plug in x = 20,000 in any one equation, the answer would be same.
So,
0.035(20,000) = $700
savings = $700

if you shift the reciprocal parent function, f(x)=1/x, right 4 units, what is the equation of the new function
Answer: I think it is f(x)=1/(x-4)
Step-by-step explanation:
By taking f(x), and applying a left or right and/or up or down transformations to it, the function could be written using the equation f(x-h)+k.
Doing so will make the graph of the function move h units to the left or right. (Positive or negative) (make sure the operation before the h is subtraction when determining the sign of h)
Also, when finding k (up and down) (positive or negative) apply this function.
f(x)=(x-h)+k
As a result, plug in your right 4 units as h, and since you are not needing to move up or down k would be 0. So, f(x)=1/(x-(4))+0 or simplified, f(x)=1/(x-4)
Answer:
F(x)=1/x-4

A baseball is hit from an initial height of 3 feet and reaches a maximum height of 403 feet. Which function could be used to model this situation, where h(t) is the height, in feet, after t seconds?
A. h(t) = -16(t - 403)^2 + 3
B. h(t) = -16(t - 5)^2 + 3
C. h(t) = -16(t - 3)^2 + 403
D. h(t) = -16(t - 5)^2 + 403
Answer:
I believe its A
Step-by-step explanation:
D. h(t) = -16(t - 5)² + 403 could be used to model this situation.
What are the given informations ?A baseball is hit from an initial height of 3 feet.
The baseball reaches a maximum height of 403 feet.
Here, h(t) indicates the height in feet after t seconds.
Which function is correct ?At the start, t = 0 & Initial height = 3 feet ,i.e. h(0) = 3
We have to verify options by putting t = 0
A. h(t) = -16(t - 403)² + 3
So, h(0) = -16(0-403)² + 3 = -16(-403)² +3 = -2598544+3 = -2598541
B. h(t) = -16(t - 5)² + 3
So, h(0) = -16(0-5)² + 3 = -16(-5)² + 3 = -400+3 = -397
C. h(t) = -16(t - 3)² + 403
So, h(0) = -16(0-3)² + 403 = -16(-3)² + 403 = -144 + 403 = -259
D. h(t) = -16(t - 5)² + 403
So, h(0) = -16(0-5)² + 403 = -16(-5)² + 403 = -400 + 403 = 3
Hence, in this function h(0) = 3 verified.
Therefore h(t) = -16(t - 5)² + 403 is the required function.
