Is it growth or decay?
Answer:
growth
Step-by-step explanation:
The base of the positive exponent is 1.1, a value greater than 1. When the growth factor is greater than 1, it is a growth function.
__
It is a decay function when the growth factor is less than 1.
if a car travels 45 miles in 30 minutes how far will the car travel in 2.5 hours
Answer:
225
Step-by-step explanation:
well divide 45 by 30 to get miles per min. = 1.5
and theirs 150 min in 2 1/2 hours
so now multiply 150 by 1.5 = 225

If y = 3x + 1 and you are given that x is equal to 2. What is the value of y in the equation?
4. Explain how to graph the equation y = -2x + 3 *
Answer:
Step-by-step explanation:
Easy way: type the equation into a graphing calculator.
__
By hand: find a couple of points and draw a line through them.
The equation is in "slope-intercept" form:
y = mx + b
where m is the slope (-2) and b is the y-intercept (3). The y-intercept is where the line crosses the y-axis, so right away you know one point on the line. That point is (0, 3).
The slope of -2 means for each horizontal unit, the line drops 2 units vertically. The point 1 unit to the right of (0, 3) is (1, 3); and the point 2 units below that is (1, 3-2) = (1, 1). So, another point on the line is (1, 1).
You can plot those two points and draw the line through them.

Answer:
m=3
Step-by-step explanation:
subtract the e from both sides so you now have 15=5m divide each by 5 and you get 3=m
Answer:
m = 3
Step-by-step explanation:
-5m + 18 = 3
-5m = 3 - 18
-5m / -15 = 3
Answer: m = 3

Compare your response to the sample response above. What did you include in your explanation? a reference to the horizontal-line test a statement that the function is one-to-one the conclusion that the inverse is a function
Answer:
all of the answers are correct
Step-by-step explanation:
i took the test and got a hundred! it's a trick question
The statements included in the explanation on the horizontal line test are follows as a reference to the horizontal-line test, a statement that the function is one-to-one. and inverse is a function.
What is the horizontal-line test?The horizontal line test is used to not only find out if a graph has an inverse function, but also if that inverse is also a function itself.
In order to pass the horizontal line test, the function has to be one-to-one which means that a horizontal line can intersect the graphed function at one point in all places.
If this happens, then there is an inverse and the inverse itself is a function.
Find out more on the horizontal line test at
brainly.com/question/11471811
#SPJ6
The complete question is
If the graph passes the horizontal-line test, then the function is one-to-one. Functions that are one-to-one have inverses that are also functions. Therefore, the inverse is a function. Compare your response to the sample response above.
The sum of three consecutive numbers is eighty-four. Create the equation you would use to solve this problem using x as the variable for the first of the three consecutive numbers. (Do not use spaces)
Answer:
27,28,29
Step-by-step explanation:
x+x+1+x+2 =84
3x +3 =84
3x=84-3
3x=81
x=81 :3
x=27 (the first number
27 +1=28 (the second number
27 +2 =29 (the third number

Answer:
Pam's house to the restaurant: 5 units
Pam's house to Jean's house: 2 units
Jean's house to the school: 6 units
Step-by-step explanation:
The distance formula is: d=√((x_2 - x_1)²+ (y_2 - y_1)²)
So, plug the coordinates into the formula for each problem:
Pam's house to restaurant:
d=√((4 +1)²+ (-2 +2)²)
d=√(5²+ 0²)
d=√(25)
d=5
Pam's house to Jean's house:
d=√((-3 +1)²+ (-2 +2)²)
d=√(-2²+ 0²)
d=√(4)
d=2
Jean's house to the restaurant:
d=√((-3 +3)²+ (4+2)²)
d=√(0²+ 6²)
d=√(36)
d=6
So:
Pam's house to the restaurant: 5 units
Pam's house to Jean's house: 2 units
Jean's house to the school: 6 units

A neighbor farmer had some chickens. She had 24 feet of wire fencing to
make a rectangular pen for the chickens. What different dimensions could
she use to build the pen if the perimeter remains fixed?
Answer:
A rectangle is defined by its length = L, and its width = W.
So the perimeter of the of the rectangle can be written as:
Perimeter = 2*L + 2*W.
In this case, we want to leave the perimeter fixed, so we have:
24ft = 2*L + 2*W.
Now, we do not have any other restrictions, so to know the different dimensions now we can write this as a function, by isolating one of the variables.
2*L = 24ft - 2*W
L = 12ft - W.
or:
L(W) = 12ft - W.
Such that:
W must be greater than zero (because we can not have negative or zero width).
And W must be smaller than 12ft (because in that case we would have zero or negative length)
Then the possible different dimensions are given by:
L(W) = 12ft - W
0ft < W < 12ft.
