Write an equation in slope-intercept form of the line that passes through the given point and is
parallel to the graph of the given equation.
(-1,6); y = 9x - 5
Answer:
y = 9x - 15
Step-by-step explanation:
The given y = 9x - 5 is already in slope-intercept form. Any line parallel to this one has an equation that looks exactly the same except for the constant term. Call the new constant term 'C.'
Start with y = 9x - 5 and substitute the coordinates of the given point (-1, 6):
6 = 9(-1) + C, or
6 + 9 = C, or
C = 15
Then the equation of the line that passes through (-1, 6) and is parallel to y = 9x - 5 is
y = 9x - 15

375 fish are swimming in a school. First, 47 fish swim away. Then 116 more fish join the school. How many fish are in the school now
Answer:
The answer is 444.
Step-by-step explanation:
First, you do 375 - 47 because 47 swam away, decreasing the amount of fish that are swimming in a school. Then, 116 fish come back to swim so you add 116 to get 444.
There are 444 fish in the school now.
What is Unitary Method?The unitary method's formula is to identify the value of a single unit, then multiply that value by the number of units to obtain the required value.
The unitary approach is used when we have several goods with varying values in our possession. To get the value of one unit, we simply divide the total value by the number of units.
We have,
375 fish are swimming in a school.
First, 47 fish swim away.
Then 116 more fish join the school.
So, the number of fish in the school now
= 375 - 47 + 116
= 444 fish
Thus, there are 444 fish in school now.

An isometric transformation is applied to a trapezoid to create a parallelogram. What is the length of JK? 6 cm 7 cm 10 cm 13 cm
Answer:
C). 10 cm
Step-by-step explanation:
A Trapezoid is characterized as a quadrilateral having two parallel(non-adjacent) sides. While an isometric transformation includes a geometric system having three equal axes lying at right angles to one another. In order to convert the trapezoid into a parallelogram, the length of JK must be 10cm(8 + 2) so that opposite edges are of equal length with an angle of 90°. Thus, option C is the correct answer.

What is the image of the point (-8,3)(−8,3) after a rotation of 270^{\circ}270
∘
counterclockwise about the origin?
Given:
The point is (-8,3).
To find:
The image of the given point after a rotation of 270 degrees counterclockwise about the origin.
Solution:
If a point is rotated 270 degrees counterclockwise about the origin, then the rule of rotation is:
[tex](x,y)\to (y,-x)[/tex]
Using this rule, we get
[tex](-8,3)\to (3,-(-8))[/tex]
[tex](-8,3)\to (3,8)[/tex]
Therefore, the image of the given point after a rotation of 270 degrees counterclockwise about the origin is (3,8).
A tennis ball has a radius of about 1.4 inches What is the volume of the tennis ball to the nearest half inch.? Use 3.14 as an approximation for
Answer:
Volume of tennis ball = 11.49 inch³
Step-by-step explanation:
Given:
Radius of tennis ball = 1.4 inches
Value of π = 3.14
Find:
Volume of tennis ball
Computation:
Volume of sphere = [4/3][π][r]³
Volume of tennis ball = [4/3][π][Radius of tennis ball]³
Volume of tennis ball = [4/3][3.14][1.4]³
Volume of tennis ball = [1.333][3.14][1.4]³
Volume of tennis ball = [1.333][3.14][2.744]
Volume of tennis ball = [4.1856][2.744]
Volume of tennis ball = 11.4852
Volume of tennis ball = 11.49 inch³

the diameter of a circle is 4 in. find its area in terms of pi
Step-by-step explanation:
A ≈12.57in²
d = Diameter
Using the formulas
A=πr2
d=2r
Solving forA
A=1/4πd²=1/4·π·4²≈12.56637in²
Answer:
A = 4π in²
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
Here d = 4, then r = 4 ÷ 2 = 2
A = π × 2² = 4π in²

32 Colton is heating a pot of water. He records the temperature of the water in
the pot every minute. This equation models Colton's data, where x represents
the number of minutes the water has been heated, and y represents the
temperature of the water in degrees Fahrenheit.
y = 7.5x + 40
What is the temperature in degrees Fahrenheit of colton's pot of water after 16 minutes. Hi Ayer boils at a temperature of 212 after 16 minutes of heating how much additional time to the nearest minute will be needed for the water to boil.
Answer:
Step-by-step explanation:
PART A
7.5 represents the ounces of water heating up inside the pot.
PART B
40 in the equation will represent the starting point. It can be described as where the temperature started.
PART C
The temperature, of Colton's pot of water after 16 minutes will be 120° 7.5(16) = 120 7.5 being the ounces of water and 16 being minutes.
PART D
After 16 minutes of heating, about 13.3 as additional time will be added for the water to start boiling at 212°.
The temperature in degrees Fahrenheit of colton's pot of water after 16 minutes is 160° F. The additional time to the nearest minute will be needed for the water to boil is 7 minutes approximately.
How to evaluate a given mathematical expression with variables if values of the variables are known?You can simply replace those variables with the value you know of them and then operate on those values to get a final value. This is the result of that expression at those values of the considered variables.
For this case, it is specified that:
y = 7.5x + 40 ( where x = number of minutes the number of minutes the water has been heated, and y represents the temperature of the water in degrees Fahrenheit.)So, if the water is boiling for x = 16 minutes, then the temperature would be:
[tex]y = 7.5 \times 16 +40 = 160^\circ \: \rm F[/tex]
Also, we need to make the temperature reach to 212 degree Fahrenheit after 16 minute of boiling.
Let it takes T time (in minutes more) to reach 212 degree Fahrenheit, then: y = 212, x = 16 + T
Putting these values in the equation, we get:
[tex]y = 7.5x + 40\\212=7.5\times(16+T) + 40\\212 = 120 + 7.5T + 40\\7.5T = 212-160\\\\T = \dfrac{212-160}{7.5} = \dfrac{52}{7.5} \approx 6.93 \: \rm minutes \approx 7 \: \rm minutes[/tex]
Thus, the temperature in degrees Fahrenheit of colton's pot of water after 16 minutes is 160° F. The additional time to the nearest minute will be needed for the water to boil is 7 minutes approximately.
