Answer:
Step-by-step explanation:
i. 4 (x - 2) = 100
x-2= 100/4
x-2=25
x=25+2
x=27
ii. 2 (x - 2) = 50
x-2= 50/2
x-2=25
x=25+2
x=27
The equation 4 (x - 2) = 100 is a true equation for x when x = 27
4 (x - 2) = 100
4x - 8 = 100
Collect like terms
4x = 100 - 8
4x = 92
Divide both side by 4
4x/4 = 92/4
x= 27
Also the equation 4 (x - 2) = 100 is the same as 2 (x - 2) = 50 when the former equation is being divided by 2.
Therefore, the equation 4 (x - 2) = 100 is a true equation for x when x = 27

what are the intersections between the lines y=x squared and 6x + 3y= 24?
Answer:
The intersection points between the functions are (-4,16) and (2,4)
Step-by-step explanation:
Intersection Between Functions
We are given the functions:
[tex]y=x^2[/tex]
[tex]6x+3y=24[/tex]
To find the intersections between them, we have to solve the system of equations. Let's start by simplifying the second equation by 3:
[tex]2x+y=8[/tex]
Now we substitute [tex]y=x^2[/tex] into this equation:
[tex]2x+x^2=8[/tex]
Solve the quadratic equation by any of the available methods.
Subtract 8:
[tex]2x+x^2-8=0[/tex]
Sort the polynomial:
[tex]x^2+2x-8=0[/tex]
Factor:
[tex](x+4)(x-2)=0[/tex]
Solve:
[tex]x=-4, x=2[/tex]
Now find the y-coordinate of each solution:
[tex]y=x^2=(-4)^2=16[/tex]
The point is (-4,16)
For x=2:
[tex]y=x^2=2^2=4[/tex]
The point is (2,4)
The intersection points between the functions are (-4,16) and (2,4)

Leann makes an average of 36 cookies per week. About how many cookies will she make in a year
Answer:
The answer is 1872 cookies.
Step-by-step explanation:
First we know that in one year there are 52.18 weeks or 52 weeks. You take that number of weeks and multiply it by 36.
If you multiply 36 by 52 you get 1872 cookies.
Or, if you multiply 52.18 by 36 you get 1878.48

A family is planning a camping trip at a state park. The state park has 9 campgrounds, each with 6 campsites. The family wants to go on a hike, and the park has 4 hiking trails. The children also want to go for a swim at one of the 4 beaches. How many different ways can the family plan a camping trip?
Answer:
62
Step-by-step explanation:
Camping trip different ways = No of campgrounds x campsites each campground
9 x 6 = 54
Hiking trip different ways = 4 (hiking trails)
Swimming different options = 4 (beaches)
Total ways of planning trip = 54 + 4 + 4 = 62

Tonya’s dog-walking service charges a flat rate of $20 per month, plus $3 per mile that each dog is walked. Beth does not charge a monthly fee for her dog-walking service, but she charges $5 per mile that each dog is walked.
Part A
Choose the equation that can be used to find the number of miles m for which Tonya and Beth would charge the same amount.
A. 20 + 3m = 5m
B. 20 = 3m + 5m
C. 20 + 5m = 3m
D. 20 + m = 8m
Part B
m = _____ miles
Answer:
A 10 miles
Step-by-step explanation:
If I'm not mistaking I'm pretty sure we can write the two problems with an equal sign between as we're trying to find the same amount.
Using this information, we know that we Automatically have a +20 charge with a 3 dollar charge for every mile walked. Now we have 20+3x=
Now we plug in the 5x to get 20+3x=5x
From here you subtract 3x and you get 20=2x. Now divide!
10=x
Hope this helps! (Side Note: You should probably get some sleep as I'm sure it's pretty late where ever you live. Also, keep trying even if you feel like giving up!) :)

What is the transformation of a graph?Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.
If we reflect any graph about y = x then the coordinate will interchange it that (x,y) → (y,x).
Given the coordinate (3,-2) transformed in coordinate (1,0)
Now,
3 + x = 1
x = -2
It means graph shift 2 units left.
Now,
-2 + y = 0
y = 2
It means the graph shifts 2 units up.
Hence "The translation of points (3,-2) → (1,0) is 2 units up and 2 units left".

The function f has the property that as x gets closer and closer to 4, the values of f(x) get closer and closer to 7. Which of the following statements must be true?
Answer:
C
Step-by-step explanation:
x going to 4 is given by limx->4 and closer to 7 is given by =7
The correct statement is [tex]\lim_{x \to 4} f(x)[/tex] = 7.
What is function?An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given statement:
x gets closer and closer to 4, the values of f(x) get closer and closer to 7.
So, x gets closer and closer to 4 shows
x-> 4
and, f(x) get closer and closer to 7 shows
f(x)=7
Combining both we can write using the limit function x gets closer and closer to 4 require limit
[tex]\lim_{x \to 4} f(x)[/tex] = 7.

How do I write this equation? Pls help ASP
This is a question about angles and equations! Let's see how to solve this.
The angle [tex]\angle PQR[/tex] is the sum of the angles [tex]\angle MQR[/tex] and [tex]\angle PQM[/tex]. So, we can do a equation with this information and solve it:
[tex]\angle PQR = \angle MQR + \angle PQM\\\\138x -1 = 115 + 23x -1\\138x - 23x = 115 + 1 - 1\\115x = 115\\x=\frac{115}{115} \\x= 1[/tex]
Therefore, the value of x is 1.
