The combined ounces of meat and cheese used on each sandwich is 7 ounces and the combined ounces of meat on all sandwiches is 52 ounces and that of cheese on all sandwiches is 39 ounces.

According to the question,

We have the following information:

A sandwich hop serve 4 ounce of meat and 3 ounce of cheese on each sandwich. After making sandwiches for an hour the hop owner has used 91 combined ounce of meat and cheese.

Combined ounces for 1 sandwich:

Ounces of meat + ounces of cheese

4+3

7 ounces

It is given that in an hour 91 ounces of combined cheese and meat are used.

Now, we have:

Number of sandwiches made in 1 hour = 91/7

Number of sandwiches = 13

Ounces of meat used in 13 sandwiches can be found using multiplication as follows:

13*4

Ounces of meat used in 13 sandwiches = 52 ounces

Ounces of cheese used in 13 sandwiches can found using multiplication as follows:

13*3

Ounces of cheese used in 13 sandwiches = 39 ounces

Hence, the combined ounces of meat and cheese used on each sandwich is 7 ounces and the combined ounces of meat on all sandwiches is 52 ounces and that of cheese on all sandwiches is 39 ounces.

After 5 years the value of the farmhouse would be $23675 more than the value of the farmhouse when it was built.

What is the exponential function?

The exponential function is a mathematical function denoted by [tex]f(x)=e^{x}[/tex]. Unless otherwise specified, the term generally refers to the positive-valued function of a real variable, although it can be extended to complex numbers or generalized to other mathematical objects like matrices or Lie algebras.

The value of a farmhouse, in dollars, x years from the year it was built can be predicted by the function

               [tex]g (x) = 65500(1.05)^x[/tex]

Now the given table shows that the value of the farmhouse over the years

Now the value of the farmhouse when it was built = $70000

Now after 5 years, the cost would be

                [tex]g(x) = 65500(1.05)^x\\\\g(5)=65500(1.05)^5\\\\g(5) = 93675\\[/tex]

Now the difference would be = 93675 - 70000

                                                 = $23675.

Hence, After 5 years the value of the farmhouse would be $23675 more than the value of the farmhouse when it was built.

By solving equations we know that he should mix 4 grams and 16 grams of the 30% and 60% bottles, respectively.

In mathematical equations, the equals sign is used to show that two expressions are equal.

According to algebra, an equation is a statement that shows the equality of two mathematical expressions.

For instance, the formulas 3x + 5 and 14, which together make the equation 3x + 5 = 14, are separated by the word "equal."

So, John requires a total of 20 grams.

Let x equal the 30% that he requires.

Let 20-x equal 60% of what he needs.

So, we have:

(x/20 * 30) + (20-x/20 * 60) = 54

Evaluate as follows:

1.5x + 60 -3x = 54

-1.5x = -6

x = 4 grams

20-x = 16 grams

Therefore, by solving equations we know that he should mix 4 grams and 16 grams of the 30% and 60% bottles, respectively.

Total number of seats for the center aisle z  = 400 + 10x + Y

The cafeteria would have a total of 3z = 1200 + 30 x + 3y chairs.

The word "total" refers to the addition of numbers or the destruction of something, and a total is a whole or full sum. In mathematics, adding two or more integers yields the sum. When you multiply 8 by 8, you get 16.

If z represents the total number of seats, then z=z1 + z2.

The equation for the first ten rows would be 10 (30 + x)= z1.

The equation for the final five rows would be 5 (20 + y) = z2.

Therefore, there would be z= z1+ z2  seats in the center aisle.

So total number of chairs in the middle aisle would be

z= z1+ z2

z= 10 ( 30 + x)+5 ( 20 + y)

z= 300 + 10x + 100 + y

z= 400 + 10x + y

The total number of chairs in the cafeteria would be z +z +z ( for the 3 aisle right , middle and left)

3z = 3(400 + 10x + y)

Therefore ,the answer that states, "Infinitely many solutions, both sides are equivalent expressions" is the one that should be selected in this case.

Equations are mathematical expressions that have two algebraic expressions on either side of an equals (=) sign.  For an unknown quantity represented by an unknown variable, equations can be solved to determine its value.

Here,

The number of solutions is unlimited if there are more variables than linear independent equations.

A single solution or no solution is possible if there are the same number of linearly independent equations and variables.

In the following scenarios, we are at a loss for solutions:

y = x + 3

y = x - 3

this causes:

x + 3 = x - 3

+3 = -3

Consequently, this system lacks a solution.

The first set of equations is

y = x + 5

y = 2x + 5

You can see that there is only one solution for this system because there are only two variables and two linear independent equations.

Thus, "One solution, the graph of these lines should connect at one point" is what we have here. The key idea is (0, 5)

Another system is:

y =x+x+5 = 2x + 5

y = 2x+ 5

Since both equations are identical and there are just two variables in this situation, there are an endless number of solutions to the system.

Quantitative data's distribution shape may be characterized as having a logical order to the numbers and allowing for the identification of the "low" and "high" end values on the histogram's x-axis. Since qualitative data are not numerical, the distribution shape cannot be specified.

Given that,

Sample size of A, n = 200

Sample size of B, n = 100

Proportion of adults in district A = 60%

Proportion of adults in district B = 45%

In the sample size of 200, the number of adults that support a new ballot measure is:

= (60%) × 200

= 120

Those that oppose is:

= 200 -120

If 45% supports a new ballot measure in district B, then 55% do not support. The difference between those that support and do not support is:

(55% - 45%) × 100

Answer:

I'm not sure but x1=3 that's all I know I didn't do it on edge tho

Answer:

  r = 11

Step-by-step explanation:

Since we have a slope and one confirmed point, a good approach would be to find the equation of the line that goes through that point.  The equation can then be used to find r, for x = 3.

The standard format for an equation of a straight line is y=mx+b, where m is the slope and b the y-intercept (the value of y when x=0).  The slope is -3:

  y = -3x + b

To find b, enter the given point and solve for b:

  -1 = -3*(7) + b  [for (7,-1)]

   b = 20

The equation for this line is y = -3x + 20

Now enter (3,r)

y = -3x + 20

r = -3(3) + 20

r = 11

The point (3,r) is (3,11)

See the attached graph

(a) This is the factored form of the equation.

(b) The x - intercepts are  (√2, 0) and (-√2, 0).

(c) The value of f(-1) is -8.

What is x - intercept?

We set y = 0 and solve the equation for x to determine the x-intercept. This is due to the fact that the line crosses the x-axis at y=0. If an equation is not in the form y = mx + b, we can still solve for the intercepts by substituting 0 where necessary and then solving for the final variable. Set x = 0 and then solve for y to find the y-intercept.

(a)  Consider, the given equation

f(x) = 8x^2 - 16

First to factor the equation.

Take 8 common from both the terms,

f(x) = 8(x^2 - 2)

This is the factored form of the equation.

(b) Now to find the x- intercept.

Let y = 8x^2 - 16

Set y = 0

So,

0 = 8x^2 - 16

8x^2 - 16 =0

x^2 - 2 = 0

x^2 = 2

x = ±√2

Hence, the x - intercepts are  (√2, 0) and (-√2, 0).

(c) Now to find the value of f(-1)

plug x = -1 in the given equation.

f(-1) = 8(-1)^2 - 16

f(-1) = 8(1) - 16

f(-1) = 8 - 16

f(-1) = -8

Hence, the value of f(-1) is -8.
