Answer:
x = - 3.75
y = 28.75
Step-by-step explanation:
[tex] \begin{cases} x + y = 25\\\\ 5x + y = 10 \end{cases} [/tex]
Since, x + y = 25
Therefore, y = 25 - x..... (1)
5x + y = 10......(2)
Plug y = 25 - x in equation (2), we find:
5x + 25 - x = 10
5x - x = 10 - 25
4x = - 15
x = - 15/4
x = - 3.75
Plug x = - 3.75 in equation (1), we find:
y = 25 - (- 3.75)
y = 25 + 3.75
y = 28.75
(x, y) = (-3.75, 28.75)

A group of friends wants to go to the amusement park. They have no more than $ 100 to spend on parking and admission. Parking is $ 8, and tickets cost $ 23 per person, including tax. Write and solve an inequality which can be used to determine x, the number of people who can go to the amusement park.
Answers
Answer:
Step-by-step explanation:
Based on the information given in the question, the inequality which can be used to determine x, the number of people who can go to the amusement park will be:
8 + 23(x) ≤ 100
8 + 23x ≤ 100
23x ≤ 100 - 8
23x ≤ 92
x ≤ 92/23
x ≤ 4
The number of people that can go to the amusement park will be at most 4

Calculate how much Belinda paid for the car.
Guys please help me with the homework it’s available for me during the day only.
Answers
Answer:
$16,500
Step-by-step explanation:
The computation of the amount that should be paid for the car is shown below:
Since the car would be purchased one year ago
And, the value of the car would be decreased by 15% to $14025
So the amount that should be paid is
= $14025 × 100 ÷ (100 - 0.15)
= $16,500
Explain how to find the value of y in the equation 6(y+4)=12
Answers
Answer:
y=-2 (Please can i have brainliest????)
Step-by-step explanation:
There are different ways to do this but my way, you would distribute 6 to both y and 4, ending up with 6y+24=12. You then subtract 24 from both sides giving you, 6y=-12. Then divide both sides by 6, giving you y=-2
Answer: y=-2
Step-by-step explanation:
First, you would distribute the 6 to both the y and the 4 which would give you 6y+24=12
Then you would subtract 24 from 12 to get -12 ( it would look like 6y= -12 after)
Finally, you would take -12/6 to get -2 so y = -2
the lablel on a 1/2- pound bag of wildflower seeds states that it will cover an area of 375 square feet . based on this information, what is the number of square feet that 1 pound of wildflower seeds will cover.
Answers
Answer: so a 1 and 1/2 bag will cover 375
1=2/2
1 and 1/2=2/2 and 1/2=3/2
so 3/2 pound covers 375
2/2 pounds covers x
3/2pound=375
multiply both sides by 2 to get rid of the fraciton
3pound=750
divide both sides by 3
1pound=250 square feet so the answer is c. 250 square feet

Answer:
1. domain and range are all real numbers
2. the relation is linear
Step-by-step explanation:
When the graph of a function is a straight line, the relation is linear. (That's what linear means.)
A linear relation is of degree 1, so has odd degree. Any odd-degree polynomial function has a domain and range of "all real numbers."
Answer:
1. Domain : all the real numbers
Range = all the real numbers
yes, this relation represents a linear function. (linear functions are always a straight line when graphed.)

[tex]19^{2}[/tex] = [tex]10^{2}[/tex] + [tex]y^{2}[/tex]
( notice I've put in a " y " , where there is a B in the formula above but that's just a letter... again.. which is just a variable... the place holder for a number... soooo..... )
361 = 100 + [tex]y^{2}[/tex] ( subtract 100 from each side of the " = " )
261 = [tex]y^{2}[/tex] ( to undo the square on the wye... square root both sides)[tex]\sqrt{261}[/tex] = y

Answer:
The owner makes $2 in sales per customer
Note: The "Amount of sales" label of the question is phrased poorly. s could be better labeled "profit from sales" or at least "Amount made from sales", etc.
Step-by-step explanation:
If you logically think about how the answer (now that you know it) relates to the question, it should make simple sense.
i.e. if you consider the first column where $24 is made from 12 customers, and divide the $24 made by the 12 customers, you'll see that each customer spends $2.
Answer:
the owner makes 2 dollars in sales every week
Step-by-step explanation:
on the chart/graph it shows 6 new customers every week and if you want to see how much more money the owner makes off of each customer then...
subtract the first weeks number of customers from the second weeks to get the answer of 6 new customers per week as you can see on the chart/graph (this really isnt to important though)
then divide the total number of customers for 1 week by the profits made for that week to get an answer of 2 dollars for customers.

is the equation of the new function?
A. g(x) = 4.2%
B. g(x) = 24
C. g(x) = . 2*
D. g(x) = 2 .4*
im not sure
The vertical stretch of the transformation of the function is g ( x ) = 4 ( 2 )ˣ
How does the transformation of a function happen?The transformation of a function may involve any change.
Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.
If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:
Horizontal shift (also called phase shift):
Left shift by c units: y=f(x+c) (same output, but c units earlier)
Right shift by c units: y=f(x-c)(same output, but c units late)
Vertical shift:
Up by d units: y = f(x) + d
Down by d units: y = f(x) - d
Stretching:
Vertical stretch by a factor k: y = k × f(x)
Horizontal stretch by a factor k: y = f(x/k)
Given data ,
Let the function be represented as f ( x )
Now , the value of f ( x ) is
f ( x ) = 2ˣ
Now , the vertical stretch of a factor of 4 is given by
The transformed function is g ( x )
g ( x ) = 4 f ( x )
On simplifying , we get
g ( x ) = 4 ( 2 )ˣ
Hence , the transformed function is g ( x ) = 4 ( 2 )ˣ

Torrie could buy 8 jars of peanut butter for 27.12 or 7 jars of peanut butter for 26.53 what is the difference in the unit rates of the jars of peanut butter?
Answers
Answer:
The difference in the unit rates of the jars of peanut butter is 0.4.
Step-by-step explanation:
In order to find the unit rates, you have to divide each price for the amount of units purchased with that price, which is:
27.12/8=3.39
26.53/7=3.79
Now, that you have the unit rate for each case, you have to subtract 3.39 from 3.79 to find the difference in the unit rates:
3.79-3.39=0.4
According to this, the answer is that the difference in the unit rates of the jars of peanut butter is 0.4.

The product of two consecutive numbers is 72. Use a quadratic equation to find the two sets of numbers.
Answers
Given:
The product of two consecutive numbers is 72.
To find:
The two numbers by using the quadratic equation.
Solution:
Let the two consecutive numbers are x and (x+1).
The product of two consecutive numbers is 72.
[tex]x(x+1)=72[/tex]
[tex]x^2+x-72=0[/tex]
Splitting the middle term, we get
[tex]x^2+9x-8x-72=0[/tex]
[tex]x(x+9)-8(x+9)=0[/tex]
[tex](x+9)(x-8)=0[/tex]
Using zero product property, we get
[tex]x+9=0[/tex] and [tex]x-8=0[/tex]
[tex]x=-9[/tex] and [tex]x=8[/tex]
If [tex]x=-9[/tex], then
[tex]x+1=-9+1[/tex]
[tex]x+1=-8[/tex]
If [tex]x=8[/tex], then
[tex]x+1=8+1[/tex]
[tex]x+1=9[/tex]
Therefore, the two consecutive numbers are either 8,9 or -9,-8.
