Step-by-step explanation:

when reflected over the y axis they numbers are in quadrant 1 which means both numbers are positive.

Answer:

(y+z=6)*-3

Step-by-step explanation:

using this would make the top equation or (y+z=6) turn negative and would be this [-3y-3z=-18) using the distributive property. Since the bottom equation has a positive 3y. The -3y from the top equation and 3y from the bottom ones cancel out leaving you with z=-17 when combining like terms.

Answer:

c is the answer since you are trying to make the ys number (-/+) of the value the other y contains

(3) so you will multiply the first equation by -3 to be able to eliminate y

Answer:

Yes, Juanita is correct.

Step-by-step explanation:

Given:

The function given is:

[tex]f(x)=x^2+64[/tex]

The roots of a function means the values of 'x' for which the function intersects or touches the x-axis. Therefore, the roots are nothing but the x-intercepts of the function.

In order to find the roots of the above function, we should equate it to 0.

So, [tex]f(x)=0[/tex]

[tex]x^2+64=0\\\\x^2=-64[/tex]

We know that, square of any number is always a positive quantity. But here, the square of 'x' is -64 which is a negative number. This is not possible.

So, there is no real solution to the given function. In other words, we can say that the function doesn't intersect the x-axis.

Therefore, Juanita is correct in her argument.

Answer:

206

Step-by-step explanation:

197 + 3 + 6 = 206

To find Jack's starting weight before he started his diet, we need to add the pounds he lost in the first and the second week back to his current weight.
Jack's current weight is 197 pounds.
In the first week, he lost 3 pounds.
In the second week, he lost 6 pounds.
So the total weight lost over the two weeks is 3 pounds + 6 pounds = 9 pounds.
Now we just add these 9 pounds back to Jack's current weight to find his starting weight before the diet.
197 pounds (current weight) + 9 pounds (total weight lost) = 206 pounds.
Thus, Jack's starting weight was 206 pounds.

Answer:

Total Cost of Week = 81.20 Euros

Total Cost of Week (in dollars) = $102.31

Step-by-step explanation:

117 km per day

You drive 7 days

So,

Total miles driven = 117 * 7 = 819 km

Mileage is 42 miles per gallon. So how many gallons would it require to drive 819 km?

819/42 = 19.5 gallons

We know 1 gallons = 3.78 liters

So,

19.5 gallons would be:

19.5 * 3.78 = 73.82 liters

1.10 Euro PER LITER, so the total cost:

Total Cost of Week = 73.82 * 1.10 = 81.20 Euros

In dollars (1 euro = 1.26 dollars):

Total Cost of Week (in dollars) = 81.20 * 1.26 = $102.31

The cost on gas is approximately 7.2 euros

Data given;

If 1mi = 1.609km

And we cover 117km daily, let's convert this into miles

[tex]1mi=1.62km\\ x mi = 117km\\ x = 117/1.62\\ x = 72.2mi[/tex]

This shows that we cover a distance of 72.2 miles daily.

But the car consumes 1 gallon in 42 miles, let's calculate the gas required to cover 72.2 miles

[tex]42mi = 1g\\ 72.2mi =x\\ x = 72.2/42\\ x = 1.719[/tex]

The total gas consumed daily is approximately 1.72 gallons.

The cost of gas daily can be calculated from the data given but we have to convert the volume from gallon to liter

1L = 0.26 gallon

xL = 1.72 gallons

cross multiply this and solve for x

[tex]x = \frac{1*1.72}{0.26}\\ x = 6.6[/tex]

This shows that we consume 6.6L daily.

But we were given that the cost of 1 liter of gas is equal to 1.10 euros

1L = 1.10 euros

6.6L = x euros

[tex]x = \frac{1.1*6.6}{1}\\ x = 7.26[/tex]

The cost of gas daily is 7.26 euros or approximately 7.2 euros.

The correct answer is B. $310 at $2 per kilogram

Step-by-step explanation:

1. Let's find out the maximum profit Ms. Ortiz can make with a loaf of tomatoes:

function p(x)=–80x² + 320x – 10

For x = 1, price per kilogram of tomatoes would be: 4 - x = 3

–80x² + 320x – 10, replacing with x = 1

-80 * 1² + 320 * 1 - 10 = -80 + 320 - 10 = 230

For x = 2 price per kilogram of tomatoes would be: 4 - x = 2

–80x² + 320x – 10, replacing with x = 2

-80 * 2² + 320 * 2 - 10 = -320 + 640 - 10 = 310

For x = 3, price per kilogram of tomatoes would be: 4 - x = 1

–80x² + 320x – 10, replacing with x = 3

-80 * 3² + 320 * 3 - 10 = -720 + 960 - 10 = 230

Answer:

x = 3

Step-by-step explanation:

Two points are given.  The x-coordinates are one and the same.  This means that x does not change, and thus the line is a VERTICAL line:  x = 3.

Answer:

see explanation

Step-by-step explanation:

(a)

A horizontal line parallel to the x- axis has equation

y = c

where c is the value of the y- coordinates the line passes through.

The line passes through (- 2, 4) with y- coordinate 4, thus

y = 4 ← equation of horizontal line

(b)

A vertical line parallel to the y- axis has equation

x = c

where c is the value of the x- coordinates the line passes through.

The line passes through (- 2, 4) with x- coordinate - 2, thus

x = - 2 ← equation of vertical line

Answer:

Here, invert the multiple of x and draw the other side, and multiply in the following equation to obtain the value of x.

Step-by-step explanation:

[tex]3.75x = 3 \\ x = \frac{3}{3.75} \\ x = \frac{300}{375} \\ \\ x = \frac{4}{5} \\ \\ x = 0.8[/tex]

The solution of expression is,

⇒ x = 0.8

Answer:

2 cups of flour

Step-by-step explanation:

To make 5 batches of cookies, 10 cups of flour are required.

To make 1 batch of cookies:

10 cups ÷ 5 cups = 2 cups of flour.

To find out how many cups of flour are required for each batch of cookies, divide the total cups of flour (10 cups) by the number of batches (5 batches), which equals 2 cups of flour per batch.

To determine how many cups of flour are needed for each batch, we can set up a simple division equation where we divide the total amount of flour by the number of batches. The student is given that 10 cups of flour make 5 batches of cookies. Using this information, we calculate the amount of flour per batch as follows:

Amount of flour per batch = Total cups of flour ÷ Number of batches

Amount of flour per batch = 10 cups ÷ 5 batches

Thus, the amount of flour required for each batch is:

Amount of flour per batch = 2 cups

Step-by-step explanation:

Multiply second equation by -1

-1 × (3x + 2y) = 3

-3x -3y = -3 now add this to the first equation

7x +2y = 17

(-3x-2y)= -3

7x +2y -3x -2y = 17 -3 (2y will eliminate -2y)

4x = 14

x = 7/2 now by using this information we found we can calculate the value for y

if 3x + 2y = 3 (replace x by 7/2)

3 ×(7/2)+2y = 3 ➡ 21/3 + 2y = 3 ➡ 2y = 3 - 21/3 ➡ 2ty = 15/2 ➡ y = 15/4

Step-by-step explanation:

The amount of pizza is same as the area. The pizza is in a shape of a circle. The area of a circle is:

[tex]A=\pi r^2[/tex]

Where

r is the radius (half of diameter)

Area of one medium size pizza is (diameter 25 means radius is 25/2 = 12.5):

[tex]A=\pi r^2\\A=\pi (12.5)^2\\A=490.87[/tex]

So, area of two of these medium size pizzas is:

490.87 * 2 = 981.74

This should be the area of the large pizza. We can find the radius of that by substituting into formula. Shown below:

[tex]A=\pi r^2\\981.75=\pi r^2\\r=\sqrt{\frac{981.74}{\pi}} \\r=17.67[/tex]

Hence, the diameter would be around:

Number of hamburgers bought is 23 and number of bags of fries bought is 14

Let "h" be the number of hamburgers bought

Let "f" be the number of bags of fries bought

Cost of one hamburger = $ 1.49

Cost of one bag of fries = $ 1.19

Given that Ben spent a total of 50.93

Thus we can frame a equation as:

number of hamburgers bought x Cost of one hamburger + number of bags of fries bought x Cost of one bag of fries = $ 50.93

[tex]h \times 1.49 + f \times 1.19 = 50.93[/tex]

1.49h + 1.19f = 50.93 ------ eqn 1

Also given that the number of hamburgers was five less than twice the amount of fries

number of hamburgers bought = 2(number of fries) - 5

h = 2f - 5  ---------- eqn 2

Let us solve eqn 1 and eqn 2 to find values of "h" and "f"

Substitute eqn 2 in eqn 1

1.49(2f - 5) + 1.19f = 50.93

2.98f - 7.45 + 1.19f = 50.93

4.17f = 50.93 + 7.45

4.17f = 58.38

[tex]f = \frac{58.38}{4.17}[/tex]

Substitute f = 14 in eqn 2

h = 2(14) - 5

h = 28 - 5 = 23

Summarizing the results:

number of hamburgers bought = h = 23

number of bags of fries bought = f = 14

Answer:

It is a vertical translation of f(x) four units downward.

Step-by-step explanation:

We are given the original equation f(x) = |x| and the transformed function is g(x) = |x| - 4.

It is clear that the transformed function that g(x) = f(x) - 4.

So, the y-value in g(x) is reduced by 4 units from the y-value of f(x) i.e. the transformation is by 4 units down of function f(x).

Therefore, it is a vertical translation of f(x) four units downward. (Answer)
