Answer:
y = -x - 5
Step-by-step explanation:
y = mx + b
slope = m = -1
y = -1x + b
y = -x + b
Plug in (-7, 2) for x and y, and solve for b.
2 = -(-7) + b
2 = 7 + b
b = -5
y = -x - 5
A new popular midsize car has a retail price of $25,000. The midsize car's value M(t) is given by the exponential model M of t is equal to 25,000 times the quantity four fifths to the power of t where t represents the time in years. Identify the domain, in yearly intervals, that contains all the years the car's value is less than $1,000.
[13, ∞)
[14, ∞)
[15, ∞)
[16, ∞)
Answer:
Its C
Step-by-step explanation:
Just finished the homework and got it right
Using exponential functions, it is found that the correct option is given by: [15, ∞)
-------------------------
The exponential function given in this exercise is:
[tex]M(t) = 25000(\frac{4}{5})^t[/tex]
-------------------------
The domain that contains all the years the car's value is less than $1,000 is composed by the values of t for which:
[tex]M(t) < 1000[/tex]
Thus, we have to solve the exponential inequality.
[tex]M(t) < 1000[/tex]
[tex]25000(\frac{4}{5})^t < 1000[/tex]
[tex](\frac{4}{5})^t < \frac{1}{25}[/tex]
[tex]\log{(\frac{4}{5})^t} < \log{\frac{1}{25}}[/tex]
[tex]-0.0969t < -1.39794[/tex]
[tex]0.0969t > 1.39794[/tex]
[tex]t > \frac{1.39794}{0.0969}[/tex]
[tex]t > 14.43[/tex]
Rounding, t greater than 15 years, and the correct option is:
[15, ∞)

1 1/11 rewrite each number as a single fraction greater then one
Answer:
12/11
Step-by-step explanation:
11/11=1
1/11=1/11
11/11+1/11=12/11
[tex]1\frac{1}{11}[/tex] rewritten as a single fraction is 12/11
[tex]1\frac{1}{11}[/tex] is a mixed fraction.
A fraction is a number that is made up of a numerator and a denominator.
A mixed fraction is made up of a whole number and a proper fraction. A proper fraction is a fraction that is made up of a numerator that is less than a denominator.
For example, [tex]\frac{1}{11}[/tex] is a proper fraction. The numerataor,1, is less than the denominator, 11.
We are to convert the mixed fraction to an improper fraction. An improper fraction is a fraction that its numerator is greater than the denominator.
In order to convert to an improper fraction, take these steps
multiply the whole number with the denominator ( 1x 11) = 11Add the numerator to the answer gotten in the previous step = 11 + 1 = 12 Divide the answer gotten in the previous step by the denominator : 12/11A similar question was answered here: https://brainly.com/question/14549871?referrer=searchResults

x: 3
f(x): -1
Step-by-step explanation:
Answer:
3/2, 1/2, - 1
Step-by-step explanation:
x + 2y = 1 --> this is 'f(x)'. Sub in the each x-value to the equations.
First part:
x = -2
x + 2y = 1
-2 + 2y = 1
2y = 3
y = 3/2
Second part:
x = 0
x + 2y = 1
0 + 2y = 1
2y = 1
y = 1/2
Third part:
x = 3
x + 2y = 1
3 + 2y = 1
2y = -2
y = -2/2
y = - 1
Given the list of numbers, 3, 2, 6, 3, 9, 5, 12, 7, if the pattern continues, what is the sum of the ninth and tenth numbers?
Answer:
Step-by-step explanation:
Every other one beginning with the first 3 adds 3 to the preceding number that has an odd position.
So the odd positions go up 3 6 9 12
And the next odd position is 15 which is the nineth term.
It's hard to tell what the even ones are doing. It could be anything just about. I'm guessing its a 9. So the tenth term is 9.
The sum of 9 and 15 = 24

Given are the slopes of several lines. Indicate whether each line is horizontal, vertical, rises from left to right, or falls from left to right.
Answer:
Rises from left to rightVertical LineHorizontal LineFalls from left to rightStep-by-step explanation:
Keep in mind we read graphs from left to right just like how we read and write.
A positive slope will be increase from left to right. A negative slope with decrease left to right. A vertical line will have a undefined slope.A horizontal line will have a slope of 0.We can use those tips to solve the problem.
Option A:
4/5 is a positive slope so it will rise from left to right.
Option B:
No slope automatically means "undefined" so that falls in the definition of a vertical line.
Option C:
A slope of 0 is defined as a horizontal line.
Option D:
-4/5 is a negative slope so it will fall from left to right.

Answer and Step-by-step explanation:
This graph is a One to One Function.
For a function to be one-to-one, each x value must have its own y-value, which is the case for this graph.
The y value of a point where a vertical line intersects a graph represents an output for that input x value. If you draw a vertical line on the graph, and it intersects more than once, then the graph does not define as a function because that x value has more than one output (y).

Calculate the straight line distance between the points (-10, -7) and (-8,1).
G.2(B)
Answer:
2√(17) or about 8.2462 units.
Step-by-step explanation:
We want to determine the distance between the two points (-10, -7) and (-8, 1).
We can use the distance formula. Recall that:
[tex]\displaystyle d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
Substitute and evaluate:
[tex]\displaystyle \begin{aligned} d &= \sqrt{((-10)-(-8))^2 + ((-7) - (1))^2} \\ \\ &=\sqrt{(-2)^2+(-8)^2} \\ \\ &= \sqrt{(4) + (64)} \\ \\ &= \sqrt{68}\\ \\ &= 2\sqrt{17}\end{aligned}[/tex]
Hence, the distance between (-10, -7) and (-8, 1) is 2√(17) units or about 8.2462 units.

The straght line distance between the two points is 8.2462 units.[tex] \rule{200pt}{3pt}[/tex]
Solution :-
As per the provided information in the given question, we have been given that:
[tex](x_1, y_1) = (-10, -7)[/tex][tex](x_2, y_2) = (-8, 1)[/tex]To calculate the distance between the two points, we will apply the formula below:
[tex] \bigstar \: \: \: \boxed{ \sf{ \: \: d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \: \: }}[/tex]
Substitute the given values into the above formula and solve for d:
[tex]\sf:\implies{ d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}}[/tex]
[tex]\sf:\implies{d = \sqrt{[-8 - (-10)]^2 + [1 - (-7)]^2}}[/tex]
[tex]\sf:\implies{d = \sqrt{(2)^2 + (8)^2}}[/tex]
[tex]\sf:\implies{d = \sqrt{4 + 64}}[/tex]
[tex]\sf:\implies\bold{d = \sqrt{68} \approx 8.2462 \: units}[/tex]
Therefore :-
The straght line distance between the two points is 8.2462 units.[tex]\\[/tex]

An athlete runs two miles in 13.5 minutes. How many minutes is this per mile?
Answer:
6.75 minutes / mile.
Step-by-step explanation:
Time: 13.5 minutes
distance: 2 miles
rate: ?
You want the units to be minutes / mile. That's not the usual units for a rate. You have to be careful how you set this up.
13.5 minutes
2 miles
13.5 /2 = 6.75 minutes / mile = 6 minutes 45 seconds / mile
