Answer:
y = -2x + 16
Step-by-step explanation:
So first you plug in the values you know into the slop int. form, equation, in which it is y = mx +b. When you plug in the slope value then you will get the equation of y = -2x +b, in which then you have to solve for the b value.
In order to solve for the b value, you then plug in the x and y values of the coordinate that is given so what you would do is this: 6 = -2(5) +b
6 = -10 +b
16 = b
So then you find out b is 16 in which you just plug back into the equation. So finally you write the equation, y = -2x+16.

Which function represents exponential growth?
a. f(x) = 3x
b. f(x) = x3
c. f(x) = x + 3
d. f(x) = 3x
FIRST PERSON TO ANSWER IS THE BRAINLIEST!!!!
PLEASE GIVE EXPLANATION OF HOW!!
Answer:
Either A or D, but the answer is [tex]f(x) = 3^x[/tex].
Step-by-step explanation:
We can check for exponential growth by checking for an [tex]x[/tex] in the exponent of a constant value in the function, which is this case for [tex]f(x) = 3^x[/tex].
f(x) = x + 3 function represents exponential growth. So the correct option is option is c.
An exponential function is a arithmetic function in the form f (x) = ax, where “x” is a variable and “a” is a constant which is know the base of the function and it will be greater than 0.
An exponential function is explain by the formula f(x) = ax, where the input variable x take place as an exponent.
The exponential curve turn on the exponential function and it depends on the value of the x.
The exponential function is an main arithmetic function which is of the form
f(x) = ax
Exponential Growth
In Exponential Growth, the quantity grow very slowly at first, and then quickly. The rate of change growth over time. The rate of growth becomes faster as time passes. The quick growth is meant to be an “exponential increase”. The formula to explain the exponential growth is:
y = a ( 1+ r )x
Where r is the growth percentage.
Therefore, f(x) = x + 3 is a function represents exponential growth.

the length of the unknown leg is?
Answer:
a = 10
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is qual to the sum of the squares on the other 2 sides, that is
a² + 24² = 26²
a² + 576 = 676 ( subtract 576 from both sides )
a² = 100 ( take the square root of both sides )
a = [tex]\sqrt{100}[/tex] = 10
An equation is shown.

An employee at a homemade wooden toy store earned $860 over the past week. The employee needs to pay 14% for Federal Income Tax and 3% for State Income Tax, both on the initial amount he earned. How much will the employee earn after paying both taxes?
$
Using Percentage, the employee earn after paying Federal income tax and state income tax is $713.8.
What is percentage?Percentage is a "number or ratio that can be expressed as a fraction of 100".
According to the question,
An employee earned $860 over the past years. The employee needs to pay 14% for income tax and 3% for state income tax
Find an employee needs to pay in Federal income tax:
[tex]\frac{14}{100}[/tex] × 860 = 120.4
Find an employee need to pay in State income tax:
[tex]\frac{3}{100}[/tex] × 860 = 25.8
In order to find an employee earn after paying both taxes only if we sum the amount of taxes paid by an employee and subtract from earned amount by past years.
860 - (120.4 + 25.8) =713.8
Hence, Using Percentage, the employee earn after paying Federal income tax and state income tax is $713.8.

A line through which two points would be parallel to a line with a slope of 3/4?
a
(0,-2) and (-4,-2)
b
(0,5) and (-4,2)
c
(0,2) and (-4,1)
d
(0,0) and (0,-2)
Answer:
F. (0, 5) and (-4, 2)
Step-by-step explanation:
We need to calculate the slope of each of the given sets of points until we find the set associated with a slope of 3/4:
F. (0,5) and (-4,2) As we go from (-4, 2) to (0,5), x increases by 4 and y increases by 3, so the slope is m = rise / run = 3/4. This is the line with slope 3/4.
y=4x+3

graph the equation y=5/2x-3
Answer:
Slope: 5/2
y-intercept: (0,-3)
The graph of the equation y=5/2x-3 is plotted.
Given data:
The linear equation is represented as y = ( 5/2 )x - 3
To graph the equation y = (5/2)x - 3, use the slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.
So, the slope is 5/2, and the y-intercept is -3.
To plot the graph, follow these steps:
Plot the y-intercept:
Start by plotting the point (0, -3), which represents the y-intercept.
Use the slope to find another point: Since the slope is 5/2, use the rise and run method. From the y-intercept point (0, -3), move up 5 units (positive 5) and then move to the right 2 units. This gives another point on the line, which is (2, 2).
Hence, the equation is y = ( 5/2 )x - 3 and the graph is plotted below.

Find the slope of y-intercept of the line represented by the table. Please look at the photo
Answer:
The slope is m= 4 and the y intercept is b= 9
Step-by-step explanation:
The slope is found by using change in y over change in x, or rise over run. From the table, this means, how much does y change for every time x goes up. As you can see, every time x increases by one, y increases by 4. So that´s your slope. The y intercept is when the line crosses the y axis, where x=0. Because you already know the slope, and that when x is one, y is 13, all you have to do is to know that going backwards by one for x means going backwards by 4 for y, and 13-4 is 9.
