The solution to the equation is f = 75.
The initial charge or setup cost is represented by the intercept or f.
What is the slope-intercept function?The linear function is expressed using the slope of the line and the y-intercept in the slope-intercept form. Its form is y = mx+ b where the slope is m and the y-intercept is b.Given equation: 270 = f + 6.50(30)
We must identify the equation's solution and explain what it represents in this situation.
The equation above is written in the form of a slope-intercept function where 6.50 is the gradient or slope of the function and 30 equals the number of shirts. The total cost of printing is 270.
The equation 270 = f + 6.50(30) can be solved as follows:
270 = f + 6.50(30)
⇒ f = 270 - 195 = 75
Therefore, the initial charge or setup cost is represented by the intercept or f. As a result, the setup fee is 65.

To evaluate a function is to replace (substitute) its variable with a given number or expression.
In other words, evaluating a function means to substitute a variable with its given number or expression.

Determine if the sequence is arithmetic. If it is, find the common difference, the 21st term, the explicit rule, the recursive rule, and the three terms in the sequence after the last one given.
33, 35, 37, 39
Answer:
Common difference = 2
21st term = 73
Explicit rule : a(n) = 31 + 2n
Three terms in the sequence after 73: 77,77,79
Step-by-step explanation:
Given:
33, 35, 37, 39
If the sequence is arithmetic it has a common difference ( same difference on each value)
d= Common difference = 35 - 33 = 37 - 35 = 39 - 37 = 2
d = 2
Explicit formula:
a(n) = a1 + d (n - 1 )
Where:
a1= first term = 33
d = common difference = 2
Replacing:
a(n)= 33 + 2 (n - 1 )
a(n) = 33 + 2n - 2
a(n) = 31 + 2n
21st term:
a(21) = 31 + 2 (21) = 31+ 42 = 73
To obtain the three terms in the sequence after 73, add the common difference 3 times.
73 + 2 = 75
75+2= 77
77 + 2 = 79
Answers:
Common difference = 2
21st term = 73

f(x) = 3 x + 1 and g (x) = 2x - 3. find f (g(x)) and g (f(x))
Step-by-step explanation:
f(x} = 3x + 1
g(x} = 2x -- 3
f(g(x)) = 3x + 1. (Calm down right?)
Let the x in the expression be (2x -- 3)
N.B x = g{x}
f(g(x)) = 3(2x --3} + 1
Open bracket
f(g(x)) = 6x -- 9 + 1
f(g(x)) = 6x -- 8...
2... Solve for g(f(x)), using the same strategy
g(f(x)) = 2x -- 3
x = f(x)
g(f(x)) = 2(3x + 1) -- 3
g(f(x)) = 6x + 2 -- 3
g(f(x)) = 6x -- 1
#AllonGod
Answer:
Step-by-step explanation:
f(g(x)) means substituting g(x) in f(x)

g(f(x)) means substituting f(x) in g(x)

Write an equation in point-slope form of the line that passes through the given points, then write the equation in slope-intercept form.
(-9,7) (9,1)
What is the point-slope form of the equation of the line?
Answer:
Equation of line is given as y = mx + c, where m is the slope and c is the y-intercept.
First find the slope.
Formula for slope is given as (y2-y1)÷(x2-x1) or (y1-y2)÷(x1-x2).
Slope = (7-1)÷(-9-9)
= -6/18
= -1/3
Equation of line is y = -1/3 + c.
Substitute either one of the points into the equation to find c.

c = 4
Hence equation of line is y = -1/3x + 4

Flora is buying dog food for her dog. She wants to buy enough to last five weeks (35 days). If her dog eats 2 cups in a day, and there are 24 cups in each bag, how many bags of dog food does Flora need to buy to last 5 weeks? ⛔️ SOLVE USING A PROPORTIONAL RELATIONSHIP GRAPH! ⛔️
When the second number in the ordered pair, b, is not equal to 0, the ratio is expressed as a/b.
Flora needs 3 bags of dog food.
How to find the food bags needed?When the second number in the ordered pair, b, is not equal to 0, the ratio is expressed as a/b.
An equation in which two ratios are made equal is known as a percentage.
As an illustration, you could express the ratio as 1: 3 if there is 1 guy and 3 girls.
Given,
Dog eats 2 cups in a day
There are 24 cups in each bag
Solution:
Dog eats one bag of food in 24 cups/2 cups = 12 days
One food bag is sufficient to feed the dog for 12 days
For 35 days, the number of food bags needed is
1/x = 12/35 where x be the number of food bags needed for the dog.
x = 2.92

After solving the question using Pythagoras' theorem we get, The ladder moving down the wall at 8 feet per second.
According to the question,
The bottom(base) of the ladder is 12 feet,
the height of the ladder is 13 feet.
Now, We have to find the top of the ladder moving down the wall
by using Pythagoras' theorem,
hypotenuse ^2 = base^2 + perpendicular ^2
13^2 = x^2 + y^2
169 = x^2 + y^2
After using Pythagoras' theorem
we have this equation and now we will differentiate both sides:

{(-9,3), (8,7), (-9, -9), (2, 4)}
{(-9,3), (8,7), (-9, -9), (2, 4)}
=======================================================
Explanation:
To find an example of a non-function, we look for (x,y) points where x repeats itself. That occurs in choice D where we have (-9,3) and (-9,-9) in the same function set.
The input x = -9 leads to multiple outputs y = 3 and y = -9 simultaneously. This is not allowed if we wanted a function.
A function is only possible if each input x leads to exactly one y output.
So this is why we look for repeated x values when trying to find non-functions. Choices A, B and C all have unique x values that don't repeat, which means those choices represent functions.
Side note: The y values can repeat, but the function won't be one-to-one.
