[tex]y = - 2x + 8[/tex]

Step-by-step explanation:

The given equation is

[tex]y = - 2x + 3[/tex]

This is the equation of line b.

We want to find the equation of line c, after b is dilated by scale factor of 2 with center (0,-2).

Note that line c and b still have the same because they are parallel.

Also the y-intercept of b is 3.

The distance of the y-intercept of line b from the center of dilation is 5.

After a dilation by scale factor of 2, the y-intercept of c will be 2(5) =10 units from the center.

The y-intercept of c will therefore be:

10+-2=8

The equation c is

[tex]y = - 2x + 8[/tex]

The equation of the line in slope intercept form is y = mx - 1/5, where m is the slope of the line.

The subject of this question is mathematics, specifically geometry, and it pertains to how to write the equation of a line in slope-intercept form given the slope and the y-intercept. However, it appears there was a typographical issue as the slope wasn't provided in the question. Let us assume that the slope of the line is m.

The slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept. In this situation, if the slope is m and the y-intercept is -1/5, the required equation of the line in slope-intercept form can be written as y = mx -1/5.

Answer:

it's 9.947

Step-by-step explanation:

for this we need an equation which contain height in it so we used volume in both so we get height

π2^2h=5*5*5

π4h=125

h=9.947

To find the depth of water in the cylinder, calculate the volume of the cube and then use that volume to find the height of the cylinder.

To find the depth of water in the cylinder, we need to calculate the volume of the cube and then use that volume to find the height of the cylinder.

The volume of a cube is given by V = s^3, where s is the length of a side.

The volume of the cube is (5 cm)^3 = 125 cm^3.

Now, we can use the formula for the volume of a cylinder, V = πr^2h, where r is the radius and h is the height.

Using the volume of the cube as the volume of the water in the cylinder, we get 125 cm^3 = π(2 cm)^2h. Solving for h, we find h = 9.278 cm.

Therefore, the depth of the water in the cylinder is approximately 9.278 cm.

The value of a car that costs $30,000 and depreciates at 6.5% annually will be $22,530 after 5 years, calculated using exponential decay.

The value of a car is $30,000 and it loses 6.5% of its value each year. To calculate the value of the car after 5 years, we can apply the concept of exponential decay. The value after one year would be the initial value minus 6.5% of the initial value. Mathematically, we can express this as:

V1 = V0 (1 - 0.065),

where V1 is the value after one year and V0 is the initial value. To find the value after 5 years, we would apply this formula iteratively or use the formula for exponential decay:

Vn = V0 x (1 - 0.065)ⁿ,

where Vn is the value after n years. Therefore:

V5 = $30,000  x (1 - 0.065)⁵,

V5 = $30,000 x (0.935)⁵,

V5 = $30,000 x 0.7510,

V5 = $22,530.

After 5 years, the value of the car will be $22,530.

The answer would be 6.5 feet.

Pre-Thinking:

Knowing that the rose bushes grow at a rate of 3/4 feet per week, we can turn that into 0.75, a decimal.

Because, we need to know the height of the rose bush in 2 weeks, multiply 0.75 by 2.

0.75 * 2 = 1.5

Answer:

F' (2, 0 )

Step-by-step explanation:

A translation < 5, - 1 > means add 5 to the x- coordinate and subtract 1 from the y- coordinate, that is

F(- 3, 1 ) → F'(- 3 + 5, 1 - 1 ) → F'(2, 0 )

The image of the point F(-3, 1) after being translated along the vector <5, -1> is (2, 0). The process involves adding the vector components to the original point's coordinates.

The initial point on the coordinate system is F(-3, 1). A translation moves a point by a specific vector. This vector is <5, -1>, meaning we move the point 5 units to the right and 1 unit down.

To perform the translation, we add the components of the vector to the coordinates of the original point. So, we add 5 to the x-coordinate (-3) and -1 to the y coordinate (1). This gives us the following results:

So, the image of F(-3, 1) after being translated along the vector <5, - 1> is the point (2, 0).

Step-by-step explanation:

The 2 pounds of chicken are required to feed 8 people.

To find out how many pounds of chicken are required to feed 8 people, we can multiply the amount of chicken required per person by the number of people:

2/5 pound of chicken per person * 8 people = 2 pounds of chicken

Therefore, 2 pounds of chicken are required to feed 8 people.

Another way to solve this problem is to use ratios. We know that we need to feed 8 people and that we have 2/5 of a pound of chicken per person. We can set up a ratio to find out how many pounds of chicken we need:

8 people / 2/5 pound of chicken per person = x pounds of chicken

To solve for x, we can multiply both sides of the equation by 2/5 pound of chicken per person:

8 people * 2/5 pound of chicken per person = x pounds of chicken

x = 2 pounds of chicken

Therefore, 2 pounds of chicken are required to feed 8 people.

Answer:

6 grams of gummy worms, 2 grams of candy corn and 2 grams of sourballs.

Step-by-step explanation:

Let the number of pounds of each ingredient be as follows:

Gummy Worms = x pounds

Candy Corn = y pounds

Sourballs = z pounds

The store makes a mixtures of 10 pounds. This means the sum of x, y and z would be 10. Setting up the equation:

[tex]x + y +z = 10[/tex]                                     (Equation 1)

The mixture calls for 3 times as many gummy worms as candy corn. This means amount of gummy worm will be 3 times the candy corn. Setting up the Equation:

[tex]x=3y[/tex]                                                  (Equation 2)

Cost of gummy worms is $1.00 per pound, candy corn cost $3.00 per pound, and sourballs cost $1.50 per pound. So cost of x, y and z pounds would be:

1x , 3y and 1.5z, respectively. The total cost of mixture is $15. So we can set up the Equation as:

[tex]x+3y+1.5z=15[/tex]                                (Equation 3)

Using the value of x from Equation 2, in Equations 1 and 3 give us following two equations:

[tex]4y+z=10[/tex]                             By substitution in Equation 1. (Equation 4)[tex]6y+1.5z=15[/tex]                        By substitution in Equation 3. (Equation 5)

Multiplying the Equation 4 by 1.5 and subtracting from Equation 5 gives us:

[tex]6y +1.5z-1.5(4y+z)=15-1.5(10)\\\\ 6y+1.5z-6y-1.5z=15-15\\\\ 0=0[/tex]

When two sides of equations turn into something that is always positive, we conclude that there are infinite number of solutions. In such cases, we fix a variable and give different values to it, to find corresponding values of other variables. Lets re-write the solution in terms of z.

From Equation 4, we have:

[tex]y=\frac{10-z}{4}[/tex]

From Equation 2, we have:

[tex]x=3(\frac{10-z}{4} )[/tex]

Therefore, the solution set will be:

[tex](3(\frac{10-z}{4} ), \frac{10-z}{4} , z)[/tex]

Now in order to find any combination of ingredient, we give any value to z. Let, z is equal to 2 grams.

So,

x would be = 6 grams

y would be = 2 grams

So, one of the possible amount of ingredients that store can use is:

6 grams of gummy worms, 2 grams of candy corn and 2 grams of sourballs.

The month in which Company B's payment will first exceed Company A's payment is C) Month 7.

Step-by-step explanation:

Step 1:

Company A offers $6,000 for the first month and increases the salary each month by $5,000.

Company B offers $700 for the first month but doubles the payments each month.

We need to determine which month company B's payment is greater than company A's payment.

Step 2:

According to the table, at month 6 company A pays $31,000 while company B pays $22,400.

However after this month, in the seventh-month company A pays $36,000 while company B pays $44,800, which is higher than company A's salary.

So The month in which Company B's payment will first exceed Company A's payment is C) Month 7.

Answer: Therefore, approximately 225/8 tiles will be needed along the 9 3/8 foot wall.

Step-by-step explanation:

To determine how many tiles will be needed along the 9 3/8 foot wall, we need to find the number of tiles that can fit in that space.

First, let's convert the mixed number 9 3/8 to an improper fraction. To do this, we multiply the whole number (9) by the denominator (8) and add the numerator (3):

9 * 8 + 3 = 75/8

Now, we have the length of the wall as 75/8 feet.

To find the number of tiles needed, we divide the length of the wall by the length of each tile. The length of each tile is 1/3 foot.

Dividing 75/8 by 1/3, we multiply the first fraction by the reciprocal of the second fraction:

(75/8) / (1/3) = (75/8) * (3/1)

Simplifying the calculation, we get:

(75 * 3) / (8 * 1) = 225/8

Therefore, approximately 225/8 tiles will be needed along the 9 3/8 foot wall.

To tile a 9 3/8 foot wall with 1/3 foot square tiles, 282 tiles are needed.

The question is asking how many 1/3 foot square tiles will be needed along a 9 3/8 foot wall in your rectangular room. To find the answer, we first need to convert the length of the wall, which is given in mixed number, into an improper fraction. So, 9 3/8 is equal to 75/8 feet. Since each tile covers 1/3 foot, the number of tiles needed along the wall will be total distance divided by the length covered by each tile.

Therefore, the number of tiles = (75/8) ÷ (1/3) = (75/8) * (3/1) = 281.25

However, because we can't use a fraction of a tile, this number needs to be rounded up. Hence, you'll need 282 tiles to cover the 9 3/8 foot wall.
