Answer:

-28x^4y^6

Step-by-step explanation:

Given are two terms as

$-4x^3y^2$ and

$7xy^4$

To find the product

we group like terms and find their product

Here we have -4 and 7 for coefficients : Product =-28

x terms are x^3 and x hence product = x^(1+3) =x^4

y terms are y^2 and y^4 hence product = y^(2+4) = y^6

Hence product is

$-28x^4y^6$

Each table at a restaurant has six chairs placed around it.

Romashka-Z-Leto [24]

Answer:

4/24

Choice B is correct

Step-by-step explanation:

From the information given, there is 1 table for every 6 chairs at the restaurant. In ratio form this can be expressed as;

1:6

The ratio that is equivalent to this given ratio is 4/24. This can easily be checked through simplification of this ratio;

4/24; If we divide both the numerator and the denominator by 4 we obtain

1/6 which is equivalent to 1:6

Use the following information for questions 1 through 6. The dietitian at a camp is planning breakfast for the first day of camp

Dima020 [189]

Answer:

Let x and y be the pieces of toast and sausage required.

Then the objective function is

Min Z=0.04x+0.08y

Constraints:

Vitamin A, 2x+4y≥20

Vitamin B, 3x+1.5y≥15

Iron, 2x+2y≥16

Sausage, y≤4

The non-negative constraints are x≥0, y≥0

Thus, the linear programming model is

Min Z=0.04x+0.08y

Subject to,

2x+4y≥20

3x+1.5y≥15

2x+2y≥16

y≤4

x≥0, y≥0

1) There are two variables in the LP model. So, option (B) is correct.

2) The LP model contains four constraints (excluding the non negative constraints). So, option (D) is correct.

3) Solving the LP model using a software, we get the solution as

z=0.4, at x=6 and y=2

So, The cost of the breakfast is $ 0.4. Option (B) is correct.

4) The breakfast should contains 6 toasts.

5) The amount of Vitamin B in the breakfast = 3(6)+1.5(2)=18+3=21 milligrams. So, option (C) is correct.

6) The amount of Iron in the breakfast= 2(6)+2(2)=12+4=16 milligrams. So, option (B) is correct.

What is the equation of the line passing through the points (4, -7.5) and (6, -3.5) in slope-intercept form?

Ratling [72]

Answer:

Your answer will be

y=2x-15.5

Step-by-step explanation:

Hi, there you must know the slope-intercept form which is

y=mx+b

m=slope

b=y-intercept

You can also use

the slope formula which is

$\frac{y_2-y_1}{x_2-x_1}$

in this case

it will look like this

$\frac{-7.5-(-3.5)}{6-4}$ = $\frac{-4}{2}$ =-2

So the slope is -2

Now we will find the y-intercept

-7.5=2(4)+b

-7.5=8+b Subtract 8 both sides

-15.5=b

Your y-intercept is -15.5

Hope this helps

Can someone please help me with this question ASAP

Lana71 [14]

Answer:

x - 7.31 ≤ 10
x ≤ 17.31

Step-by-step explanation:

let x = the amount of money in the second piggy back

We assume that the second piggy bank has MORE than the piggy bank with $7.31 in it:

x - 7.31 ≤ 10

<u>Solution</u>

Add 7.31 to both sides: x - 7.31 + 7.31 ≤ 10 + 7.31

⇒ x ≤ 17.31
