you need to add together all the milkshakes sold and then add together the amount of money made and then divide the two numbers. i think this is right. hope i helped. i think your answer should be around 7 dollars for a milkshake.

The price of one chocolate shake is $9 if the milkshake vendor sells shakes in three different flavors: mango, strawberry, and chocolate option (D) is correct.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have:

A milkshake vendor sells shakes in three different flavors: mango, strawberry, and chocolate.

Let x be the price of one mango shake

Let y be the price of one strawberry shake

Let z be the price of one chocolate shake

From the question we can frame three linear equations in three variables:

16x + 13y + 29z = 419

26x + 19y + 45z = 649

6x + 11y + 0z = 96

After solving the above system of equations:

x = $5

y = $6

z = $9

Thus, the price of one chocolate shake is $9 if the milkshake vendor sells shakes in three different flavors: mango, strawberry, and chocolate option (D) is correct.

Option A (y=-2x-3) is the answer.

Step-by-step explanation:

First, you need to multiply the -2 by what is in the parentheses, in order to expand the equation. -2*x is -2x, and -2*4 is -8. This leaves you with -2x-8 on the right side of the equation.

Next, you need to isolate y on the left side of the equation. You can do this by subtracting -5 from both sides. Subtracting a negative causes it to become positive, so you are really just adding 5 to both sides.

This makes it so the y is now alone, and the right side has -2x-8+5. We add together the -8 and 5 to leave us with -3.

This makes the answer y=-2x-3.

Answer:The answer is A. You have to solve for Y .

the two points are [tex](x_{1} ,y_{1} ) & (x_{2} ,y_{2} )[/tex].

so,  lets take two points (0,0) & (25,20)

lets put the value in equation,

   m = [tex]\frac{20 -0}{25-0} = 0.8\\now \\ y - y_{1} = m(x - x_{1}) \\\\[/tex]

      y - 0 = 0.8 (x-0)

       y = 0.8x

Therefore, the correct option is  (A)0.8x.

Answer:

Step-by-step explanation:

See the attached document

Answer:

y = mx + 5; m < 0

Step-by-step explanation:

The question mentions that the slope of the line is negative and the y-intercept is 5. The general form of the straight line is given by y = mx + c. Since "c" in the equation is the y-intercept, therefore, c = 5. This means that all the straight lines passing from the point (0,5) can be expressed in a general form y = mx + 5. However, the question mentions that the slope is negative and demands the general equation of all the negatively-sloped straight lines passing from (0,5). Therefore, for the condition to be met, m has to be negative. So the correct answer is y = mx + 5, where m is negative.

Answer:

Step-by-step explanation:

1250 feet *12 inches per foot : 25 inches

15000 inches : 25 inches

Scale = 600:1 in other words 600 inches of the building represents 1 inch of the model.

If you want the scale to be feet  of building per inch of the model, then don't multiply by 12

1250 feet : 25 inches

25 feet of building: 1 inch of the model.

Answer:

The scale is 1:600

Step-by-step explanation:

To calculate the scale you have to divide the two values of height for this case, but in the same units. So 1250 feet is equal to 15000 inches. Dividing 15000 by 25 is equal to 600, that is the scale. 1:600.

Answer:

y = mnp/(m + n)

Step-by-step explanation:

I assume that both capital y and small case y are meant to be the same variable. If not, let me know, and I'll solve it again for small case y.

y/m + y/n = p

Factor y out on the left side.

y(1/m + 1/n) = p

y = p/(1/m + 1/n)

Multiply the right side by (mn)/(mn).

y = pmn/[(1/m + 1/n)mn]

y = pmn/(n + m)

y = mnp/(m + n)

Solve for y:

y/m + y/n = p

yn + ym = pmn

y = pmn / n + m

To find the inverse of the function [tex]\( y = e^{x+3} - 4 \)[/tex], we'll first swap the roles of x and y and then solve for y.

1. Start with the original function:

[tex]\[ y = e^{x+3} - 4 \][/tex]

2. Swap x and y:

 [tex]\[ x = e^{y+3} - 4 \][/tex]

3. Solve for y:

[tex]\[ x + 4 = e^{y+3} \] \[ e^{y+3} = x + 4 \][/tex]

4. Take the natural logarithm (ln) of both sides to isolate y:

[tex]\[ \ln(e^{y+3}) = \ln(x + 4) \][/tex]

[tex]\[ y + 3 = \ln(x + 4) \][/tex]

8t(t - 5)^2

Step-by-step explanation:

I would immediately rearrange these terms in descending order by powers of t:

8t^3 - 80t^2 + 200t

Then I'd factor out 8t:

8t(t^2 - 10 t + 25).

Finally, I'd factor the quadratic t^2 - 10 t + 25:

(t - 5)^2

and so 200t+8t^3-80t^2 in factored form is 8t(t - 5)^2.

Answer:

The solution of the given equation is (5/2, 1/3)

Step-by-step explanation:

It is given an equation,

(2x - 5)(3x - 1) = 0

To find the solution of given equation

(2x - 5)(3x - 1) = 0 means that,

either (2x - 5) = 0 or (3x - 1) = 0

If 2x - 5 = 0

2x = 5

x = 5/2

or 3x - 1 = 0

3x = 3

x = 1/3

Therefore the solution of the given equation is (5/2, 1/3)

ANSWER

[tex]\: x =2 \frac{1}{2} \: or \: x = \frac{1}{3} [/tex]

EXPLANATION

The equation is given in the factored form as:

Answer:

y = -⅘x - 4

Step-by-step explanation:

. So your point is an x-intercept. It happens at times. Alright. Now, we have to know that parallel lines have SIMILAR RATE OF CHANGES [SLOPES], so we keep the -⅘. Moving forward, we simply plug the coordinate into the Slope-Intercept Formula, y = mx + b --> 0 = -⅘[-5] + b. From this, we can see that our y-intercept is [0, -4], so our parallel line is y = -⅘x - 4. Do you understand?

Your question asks which pair represents the y-intercept in the equation.

To find the answer in your question, we are going to need to find the key terms in the question.

Key terms:

y-intercept

y = -5x + 6

With the information above, we can find the answer.

We know that the equation is similar to the equation: y= mx + b

We need to find what the y-intercept is in the equation.

When you look at the equation, y = -5x + 6, you would know that the y intercept would be the last number (6). Therefore, 6 would be our y intercept.

But, we need to get the number 6 in the right ordered pair.

An ordered pair is represented as (x,y).

So, we would plug in the 6 in the y spot, since it's the y-intercept. We would plug in 0 to x, since we're only focusing on the y-axis, any number on this would not allow the ordered pair to be on the y-axis.

This means that your ordered pair should be (0,6).

C). (0,6) should be your FINAL answer

The y-intercept of the equation y = -5x + 6, is represented by the ordered pair (0,6). This is established by substituting x=0 in the equation, which results in y = 6. Hence, the line intersects the y-axis at this point on a graph.

In the equation y = -5x + 6, the y-intercept is the value of y when x equals zero. This can be determined by substituting x=0 into the equation. So, let's do this:

Substitute x = 0 into the equation, we get: y = -5*(0) + 6, which simplifies to y = 6. Therefore, the y-intercept is 6, and in an ordered pair it is represented as (0,6).

So, the correct answer is option C: (0,6). This is the point where the line crosses the y-axis on a graph.
