Answer:
The cost of one hamburger is $2.19.
Step-by-step explanation:
Let h = cost of a hamburger
f = cost of a french fries
3h + 4f = 10.77-------->3h + 4f = 10.77
4h + 2f = 10.86------->8h + 4f = 21.72
---------------------
5h = 10.95
h = 2.19, f = 1.05
Find the inverse of y=7x+3
Answer:
7 x 3 .
Step-by-step explanation:
Divide x x by 1 1 . Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=3√49x7 f - 1 ( x ) = 49 x 3 7 is the inverse of f(x)=7x3 f ( x )
The inverse function is y= (x-3)/7
What is a function?An expression which defines the relationship between two variables (one independent and one dependent variable).
What is dependent and independent variable?The independent variable is the variable being controlled in the problem, and the dependent variable is the variable that changes with the change of independent variable.
What is inverse of a function?A function that undoes the original function is called the inverse function.
How to find the inverse of y=7x+3 ?To find the inverse function of a given function,
first we will have to interchange the variablesIn the problem,
y is the independent variable x is the dependent variabley=7x+3
To find the inverse
x = 7y + 3 ( interchanging the variables )
Now finding the value of y,
⇒ x - 3 = 7y
⇒ y = (x-3)/7
This is the inverse function.

So I am looking at the method of elimination but I get a little bit lost why there is a positive +1 underneath the -1 , where does the +1 come from?
Answer:
it is because its being carried to the other side
Step-by-step explanation:
When you add 1 to negative 1 it becomes 0, so we are trying to make the right hand side equal to the left hand side. If that makes any sense.

Part (a)
The notation [tex]A \cap B \cap C[/tex] talks about overlapping or intersecting all three intervals. Your teacher wants to know what numbers are in all three intervals at the same time.
Refer to the diagram below. I've graphed regions A, B and C on the same number line. The vertical separation is to help tell the regions apart. Technically they should all be on the same number line. Notice how the regions overlap on the interval (0, 2] which translates over to [tex]0 < x \le 2[/tex] telling us that the answer must be choice D.
Meaning we exclude 0 but keep 2, and everything in between the endpoints.
Choice C is not possible because x = -1 is not in region C. This means choice A is ruled out also. Choice B is eliminated because x = 3 is not in region A nor region B.
Answer: Choice D=============================================================
Part (b)
As mentioned earlier, the intervals all have in common the region between x = 0 and x = 2. We exclude 0 but keep 2.
Answer: (0, 2]=============================================================
Part (c)
The graph is shown below.
We have an open circle at 0 and a closed circle at 2. There is shading in between those endpoints.
When it comes to graphing the final answer, you'll ignore the separate regions A,B,C and only graph what is shown in purple.

The value of the expression 6 (d - f) + f when d = 4 7/8 and f = 3 1/2 is 47/4 or [tex]11\frac{3}{4}[/tex] .
How to Solve Algebra expression?6 (d - f) + f
when d = 4 7/8 and f = 3 1/2
Given the data in the question;
d = 4 7/8 = f = 3 1/2 = What is 6 (d - f) + f = ?First, we convert the mixed fraction into an improper fraction
d = 4 7/8 = ( 8×4 + 7 )/8 = 39/8
f = 3 1/2 = ( 2×3 + 1 )/8 = 7/2
Now, we substitute the values of d and f into the expression.
234/8 - 42/2 + 7/2
234/8 - 168/8 + 7/2
33/4 + 7/2

Kansas City, mo and St. louis, mo are 248 miles apart. On a map, these two cities are 4.9 cm apart. Use this scale to determine the distance between Kansas City, mo and Louisville, KY if they at 10 cm apart on the map.
Answer:
506, 12 miles
Step-by-step explanation:
Find the measurements of a mile in centimeteres
1 mile= 160934 cm
Mulitply the miles by the amount of centimeteres in a mile.
248 x 160934= 39911632
Divide it by measurement on map to find the measurement of 1 cm on the map to real life measurement in cm
39911633 ÷ 4,9= 8145231,02 cm
Once you have the ratio multipyly it by measurement on map
10 x 81452310,2
Then divide by the amount of cm in a mile
81452310,2÷160934=506,12 miles

Kansas City and St. louis are 248 miles apart. On a map, these two cities are 4.9 cm apart. Using unitary method, the distance between Kansas City and Louisville is 506 miles (approximately) if they at 10 cm apart on the map.
What is map?Making a map or using a matching procedure wherein the points of one set are compared to the points of another provides the definition of mapping. Making a map to find your residence is an aspect of mapping.
What is unitary method?
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
4.9 cm on a map in reality = 248 miles1 cm on a map in reality = 248/4.9 = 50.61 miles10 cm on a map in reality = 50.61 * 10 = 506.1 miles.

If you add Natalie's age and Fred's age, the result is 43. If you add Fred's age to 4 times Natalie's age, the result is 88. Write and solve a system of equations to find how old Fred and Natalie are.
Natalie's age = n
Fred's age = f
n + f = 43
4n + f = 88
f = 43 - n
4n + (43 - n) = 88
3n + 43 = 88
3n = 45
n = 15
f = 43 - n
f = 43 - 15
f = 28
Natalie is 15
