if was x was 3 and y was 5 what is 2xsquared plus 3ysquared

Answer:

It will cost $121.50

Step-by-step explanation:

C = 20 + 25h + .05m

Now plug in the hours and miles

C = 20 + 25(4) + .05(30)

C = 20 + 100 + 1.5

C = 121.50

The total cost rent the truck for 4 hours and 30 miles drive is $121.5.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

Given that, a home improvement store charges $20 to rent a small truck for 1 hour.

Let the number of hours be h and the number of miles be m.

Now, total charge = 20+25h+0.05m

Here, h=4 and m=30

So, total charge = 20+25(4)+0.05(30)

= $121.5

Therefore, the total cost rent the truck for 4 hours and 30 miles drive is $121.5.

Answer:

See attachment for graph

Step-by-step explanation:

Given

[tex]3x - 4y = 8[/tex]

Required

Graph the line

First, we calculate the intercepts

Set x = 0

So:

[tex]3x - 4y = 8[/tex]

[tex]3*0 - 4y = 8[/tex]

[tex]- 4y = 8[/tex]

Divide by -4

[tex]y = -2[/tex]

So, we have:

[tex](x,y) = (0,-2)[/tex]

Next, set y = 0

So:

[tex]3x - 4y = 8[/tex]

[tex]3x - 4 * 0 = 8[/tex]

[tex]3x = 8[/tex]

Divide by 3

[tex]x = 8/3[/tex]

So, we have:

[tex](x,y) = (8/3,0)[/tex]

The graph to be plotted must pass through [tex](x,y) = (0,-2)[/tex] and [tex](x,y) = (8/3,0)[/tex]

Answer:

r=-6

Step-by-step explanation:

[tex]m=\frac{y2-y1}{x2-x1} \\\frac{3-r}{6-(-6)} =\frac{3}{4} \\4(3-r)=3(12)\\12-4r=36\\-4r=24\\r=-6[/tex]

Step-by-step explanation:

= 2x +b

Use the given point (2, 5)

5 = 2(2) +b

b = 5 -4 = 1

The equation of the line is

y = 2x +1

Note general form of the slope-intercept form of a line is y = mx +b, where m is the slope and b is the y-axis intercept

Answer:

2ap + aq - bq -2bp = (a - b)(2p + q)

Step-by-step explanation:

(2ap + aq) - (bq -2bp)

a(2p +q) -b(q + 2p)    [ taking a common from the first, and b from the second]

(2p + q) [a - b]           [takin (2p + q)]

(2p + q)(a - b)

The completely factored form of the expression 2ap + aq - bq - 2bp is

(a - b)(2p + q).

In order to completely factorize the given expression, we need to look for common factors and apply factorization techniques.

Given expression: 2ap + aq - bq - 2bp

Step 1: Look for common factors.

Notice that 'a' is common in the first two terms, and '-b' is common in the last two terms.

Step 2: Factor out the common terms.

We can factor 'a' from the first two terms: a(2p + q)

And factor '-b' from the last two terms: -b(q + 2p)

Step 3: Rearrange the expression.

Now we have: a(2p + q) - b(q + 2p)

Step 4: Factor by grouping.

We can see that (2p + q) is common in both terms, so we can factor it out: (2p + q)(a - b)

Step 5: Final result.

Thus, the completely factored form of the given expression is

(a - b)(2p + q).

The true statement

The attached graph is a linear graph.

From the graph, we have:

[tex](x_1,y_1) = (0,0)[/tex]

[tex](x_2,y_2) = (1,14)[/tex]

The rate (m) is:

for some constant k.

Solving for k, we find ...

  k = w/t

Using the given values, we find k to be ...

  k = (32 ounces)/(4 seconds) = 8 ounces/second

The units are stated in the definitions of the variables, so we can write the equation as ...

Answer:

B

Step-by-step explanation:

We want to find the point-slope equation of a line that passes through the points (-1, 4) and (8, -2).

Point-slope form is given by:

[tex]y-y_1=m(x-x_1)[/tex]

Where m is the slope and (x₁, y₁) is a point.

So, let's find the slope of the line first. We can use the slope formula:

[tex]\displaystyle m=\frac{\Delta y}{\Delta x}=\frac{-2-4}{8-(-1)}=\frac{-6}{9}=-\frac{2}{3}[/tex]

We can choose (-1, 4) as our point. So, (x₁, y₁) = (-1, 4).

Substitute:

[tex]\displaystyle y-(4)=-\frac{2}{3}(x-(-1))[/tex]

Simplify:

[tex]\displaystyle y-4=-\frac{2}{3}(x+1)[/tex]

Therefore, our answer is B.

He sold $4950 worth of items. Take 12% of this amount to get

12% of 4950 = 0.12*4950 = 594

So he earns $594 in commission on top of the $350 base salary paid every week. In total, he earns 594+350 = 944 dollars for that week

This isn't the per week pay because he would need to sell exactly $4950 worth of goods each week to keep this same weekly pay.

Answer:

x=4 and y=−4

Step-by-step explanation:

Let's solve your system by elimination.

−x−2y=4;3x+2y=4

−x−2y=4

3x+2y=4

Add these equations to eliminate y:

2x=8

Then solve 2x=8 for x:

2x=8

2x

2

=

8

2

(Divide both sides by 2)

x=4

Now that we've found x let's plug it back in to solve for y.

Write down an original equation:

−x−2y=4

Substitute 4 for x in−x−2y=4:

−4−2y=4

−2y−4=4(Simplify both sides of the equation)

−2y−4+4=4+4(Add 4 to both sides)

−2y=8

−2y

−2

=

8

−2

(Divide both sides by -2)

y=−4

Answer:

Overall, it depends what type of coin you are using because each ones size is different. Or, if you are referring to the riddle it will be just one coin.

The correct answer is approximately 3,968 coins can be placed in the empty money box based on estimation. Based on these calculations, you can roughly estimate  a volume  calculation that  place around 7936 coins in your empty money box, assuming the coins are similar in size to a quarter.

To estimate the number of coins that can fit in your money box, we need to consider the volume of the box and the volume of a single coin.

Calculate the volume of the money box:

Volume = Length * Width * Height

Volume = 10 inches * 10 inches * 5 inches

Volume = 500 cubic inches

Estimate the volume of a single coin. Let's assume a common coin, such as a quarter:

Diameter of a quarter ≈ 0.96 inches

Thickness of a quarter ≈ 0.07 inches

Volume of a coin ≈ π * ([tex]radius^2[/tex]) * thickness

Volume of a quarter ≈[tex]3.14 * (0.48) ^2 * 0.07[/tex]inches

Volume of a quarter ≈ 0.063 cubic inches

Calculate the number of coins that can fit in the money box:

Number of coins ≈ Volume of the money box / Volume of a coin

Number of coins ≈ 500 cubic inches / 0.063 cubic inches

Number of coins ≈ 7936 coins (approximately)

Therefore, approximately 3,968 coins can be placed in the empty money box based on estimation. Based on these calculations, you can roughly estimate  a volume  calculation that  place around 7936 coins in your empty money box, assuming the coins are similar in size to a quarter.
