To find slope you would use the slope formula of (y2-y1)/(x2-x1). This gives us the slope of -5/4. Then we find the y-intercept. When looking on the graph we see the only y intercept is the point (0,3), so we get the number 3.

Answers
I am taking 7I+x to mean 71+ x.
Answer: y=1.837
Step-by-step explanation:
Step 1
Let y is inversely proportional to 7I+x be mathematically be written as
y ∝ 1/7I+x
Introducing our proportionality of constant , K we have that
y ∝ 1/7I+x
y =K 1/7I+x
y= K/ 7I+xh
Step 2
so when x= 8, and y =2, k becomes
y= K/ 7I+x
k= y x (7I+x)
=2 x (71 + 8)
2x 79
=158
when x= 15, y =?
y= K/ 7I+x
y= 158/ 71 + 15
y=158/86
y=1.837

The new function is g(x) = x² +1
Step-by-step explanation:
Explanation:-
Given that the function f(x) = x²
From graph ,
The parabola y = x² is shifting to up with '1' units
y = x² +1
The new function is g(x) = x² +1
Verification:-
y = x²+1
Put x=0 ⇒ y =1
The point (0,1) lies on the parabola y = x²+1
similarly put x =1 and y = 2
The Point (1,2) lies on the Parabola y = x²+1
∴ The new graph y = x²+1

A walking track is 2 1/2 miles long. How many feet is that?
Answers
Answer:
13,200 feet
Step-by-step explanation:
Answer:
13,200 feet
Step-by-step explanation:
In one mile, there are 5,280 feet.
You're trying to find how many feet are in 2.5 miles, so you can set up a proportion.
X = the number of feet in 2.5 miles.
[tex]\frac{1 mile }{5280 feet} = \frac{2.5 miles}{X feet}[/tex]
To find X, all you need to do is cross multiply.
So,
X = 5280 × 2.5 = 13,200 feet

Answer:
x = 118 degrees approximately
Step-by-step explanation:
Here, we want to get the measure of the angle marked x
We shall use the side facing it and apply the cosine rule
The side facing the angle measures 90
Thus, we have it that;
90^2 = 55^2 + 50^2 - 2(50)(55) cos X
2575 = - -5,500 cos X
X = cos^-1(-2575/5,500)

If there are 22 successes in a sample with a size of 40, what is the sample
proportion?
A. 0.55
B. 0.65
C. 0.44
D. 0.22
Answers
Answer:
A
Step-by-step explanation:
22 successes out of a group of 40 means 22/40 were good. Now, simplify 22/40. Both can be divided by 2.
22/2 = 11
40/2 = 20
Now you have 11/20. Put this in decimal form and you have 0.55
Option A answer is 0.55
What is the proportion of a sample?The proportion of a sample is the ratio of the number of successes or defeats to the total size of the sample, it is used for understanding which trend is more followed and also has many uses in the real world.
The solution to the given problemThe size of the sample is 40.
There are 22 successes in the sample.
To find the proportion of success we have to find the ratio of 22 and 40 which is 11:20, and in numerical terms 0.55
Hence option A is correct, the proportion is 0.55

Last week, an online site received $355.60 for selling 20 cell phone accessories Cell phone cases sell for $10.98 and Airpods sell for $27.98.
1. Define the variables.
2. Then, write the system of equations to model this situation.
Answers
Answer:
i. Cell phone cases
Airpods
ii. x + y = 20 .............. 1
10.98x + 27.98y = 355.60 .............. 2
iii. x = 12, and y = 8
Step-by-step explanation:
Amount of sale = $355.60
Cost of Cell phone cases = $10.98
Cost of Airpods = $27.98
Number of phone accessories sold = 20
1. The variables to be considered in the question are:
i. Cell phone cases
ii. Airpods
2. Let the number of cell phone cases bought be represented by x, and that of airpods be represented by y.
Thus,
x + y = 20 .............. 1
10.98x + 27.98y = 355.60 .............. 2
From equation 1,
x = 20 -y
substitute the value of x in equation 2
10.98(20 - y) + 27.98y = 355.60
219.6 -10.98y + 27.98y = 355.60
17y = 136.60
y = [tex]\frac{136.60}{17}[/tex]
y = 8.0353
So that,
x = 20 -y
= 20 - 8.0353
x = 11.9647
Thus,
x = 12, and y = 8
The following three shapes are based only on squares, semicircles, and quarter circles. find the perimeter and the area of each shaded part. give your answer as a completely simplified exact value in terms of π (no approximations).
I need this answer really fast. As soon as possible.
Answers
Step-by-step explanation:
Area of Shaded part
= 2 * Area of Quarter-circle - Area of Square

Perimeter of Shaded part
= 0.5 * 2π(8)

The perimeter of the shaded part is 8πcm and the area of the shaded part is 8πcm and 0.5π(8)² - 8² respectively

Particle x moves along the positive x-axis so that it's position at time t is less than equal to 0 is given by x(t)= 5t^3 - 9t^2 + 7. Is particle x moving toward the right at time t=1?

So, at [tex]t=\frac{6}{5}[/tex], the velocity changes towards the right.
Velocity:Velocity is the prime indicator of the position as well as the rapidity of the object. It can be defined as the distance covered by an object in a unit of time. Velocity can be defined as the displacement of an object in a unit of time.Given that,
