Answer:
The Cheetah's initial speed is 19.4 miles per hour
Step-by-step explanation:
Since the Cheetah is initially running and then gradually increases its speed by 50.6 miles per hour to reach a top speed of 70 miles per hour, let the Cheetah's initial speed be u.
Also, let the increase in the Cheetah's speed be Δu and let v be the Cheetah's final speed.
Now, the final speed, v = initial speed, u + change in speed, Δu
So, v = u + Δu
So, the Cheetah's initial speed is u = v - Δu
Now, v = 70 mi/h and Δu = 50.6 mi/h
Substituting v and Δu into the equation, we have
u = v - Δu
u = 70 mi/h - 50.6 mi/h
u = 19.4 mi/h
So, the Cheetah's initial speed is 19.4 miles per hour

The larger number is 8 while the smaller number is 2. The slope and y-intercept of the equations y = –x + 10 and y = 4x are different so the system has exactly one solution.
What is the equation?The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
In another word, the equation must be constrained with some constraints.
As per the given system of equations,
x + y = 10, y = 4x
The slope and y-intercept of (x + y = 10 ⇒ y = -x + 10) will be -1 and 10.
The slope and y-intercept of y = 4x will be 4 and 0.
Substitute, y = 4x into x + y = 10
x + 4x = 10
5x = 10
x = 2
And, y = 4 x 2 = 8
Hence "The larger number is 8 while the smaller number is 2. The slope and y-intercept of the equations y = –x + 10 and y = 4x are different so the system has exactly one solution".

Input 1 2 3 4 output -8 -11 -14 -17 what is the rule
Answer:
The function rule is: [tex]y = -3x-5[/tex]
Step-by-step explanation:
Using the given input/output values, we can take two pairs of input-output values for finding the rule.
The function is a linear function as the input and output are changing linearly.
Required pairs are:
(1,-8) and (2, -11)
The general rule for linear function is:
[tex]y = mx+b[/tex]
m is the slope of the function calculated using the formula
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Putting the values
[tex]m = \frac{-11+8}{2-1}\\m = \frac{-3}{1}\\m = -3[/tex]
Putting in equation
[tex]y = -3x+b[/tex]
To find the value of b, putting (1,-8) in the equation
[tex]-8 = -3(1) +b\\-8 = -3+b\\-8+3 = b\\b = -5[/tex]
Putting the values
[tex]y = -3x-5[/tex]
Hence,
The function rule is: [tex]y = -3x-5[/tex]

4. Bobbie scores m marks in a test.
Georgia scores three times as many marks as Bobbie.
Marks of Bobbie = x
Then, marks of Georgia
= 3 times marks of Bobbie
= 3 times m
= 3 × m
= 3m
What’s the slope?? Please help
Answer:
m = 30
Step-by-step explanation:
To find the slope, you can use the formula [tex]y_{2}-y_{1}\\x_{2}-x_{1}[/tex] (there should be a line between the y's and the x's to show division). Because in the numerator of the formula we have y2 - y1, we insert the second value of y and the first value of y, so it'll be 150 - 60 and we get 90. We do the same for the denominator, which will be 5 - 2 and we get 3. After this, we divide the top by the bottom, so we have 90/3 = 30.

A new health drink has 110 % of the recommended daily allowance (RDA) for a certain vitamin. The RDA for this vitamin is 50 mg. How many milligrams of the vitamin are in the drink? There are nothing mg of the vitamin in the drink.
Answer:
55mg
Step-by-step explanation:
In order to calculate the total number of vitamin mg are in the drink we first need to turn the percentage of vitamin mg in the drink into a decimal. We do this by dividing the percentage by 100 like so...
110 / 100 = 1.1
Now that we have the decimal value of the percentage we simply multiply it by the recommended daily allowance (RDA) for this vitamin.
1.1 * 50mg = 55mg
Finally, we can see that the new health drink contains 55mg of this vitamin.

There are 80 dogs and cats in the animal shelter. The ratio of dogs to cats is
5
How many of the animals are dogs?
11
A.) 30
B.)25
C.)15
D.) 36
Answer:
36 I think
Step-by-step explanation:
The number of dogs is 25
The number of cats is 55.
What is a ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
We have,
Total number of dogs and cats = 80
The ratio of dogs to cats is 5:11.
Consider the number of dogs and cats to be 5x and 11x.
We can write,
5x + 11x = 80
16x = 80
Divide both sides by 16.
x = 80 / 16
x = 5
Now,
We will substitute x = 5 to find the following:
The number of dogs:
= 5x
= 5 x 5
= 25
The number of cats:
= 11x
= 11 x 5
= 55
Thus,
The number of dogs is 25
The number of cats is 55.
