Answering guessing it’s proper fraction

Step-by-step explanation:

Answer:

The total cost would be $32

$12 for the pencils

$20 for the pens

The total cost if you buy 4 packs of pencils and 4 packs of pen at $3 and $5 respectively is $32.

Given the following data:

To determine the total cost if you buy 4 packs of pencils and 4 packs of pen:

First of all, we would determine the cost of 4 packs of pencils:

[tex]4 \;packs = 3 \times 4[/tex]

Four (4) packs of pencils = $12

For pen:

[tex]4 \;packs = 5 \times 4[/tex]

Four (4) packs of pen = $20

For total cost:

[tex]Total \;cost =12+ 20[/tex]

Total cost = $32

Answer:

(13/8, -5/4)

Step-by-step explanation:

substitute the value of y

{y=6x-11

2x-3y=7

solve the equation

2x-3(6x-11)=7

Substitute the value of x

x=13/8

Solve the equation

y=6x13/8-11

A possible solution is

y=-5/4

Check the solution

(x,y)=(13/8, -5/4)

Simplify

{-5/4=6x13/8-11

2x13/8-3x(-5/4)=7

The ordered pair is a solution

{-5/4=-5/4

7=7

Solution

Step-by-step explanation:

(4.4)^2 = b^2 + (2)^2

(4.4)^2 - (2)^2 = b^2

root 19.36 - 4 = b

root 15.36 = b

8 root 6/5 (8 root 6 divided by 5) = b

Area of the parallelogram = b × h

= (8 root 6 divided by 5) × 4.4

= 17.24440779 cm^2

A line totally can have a line of symmetry. while it does not have width (therefore cannot put the line of symmetry through its "width"), it does have a length like any other shape. If we take a 4 unit line, we could put the line of symmetry at the 2 unit mark.

^sorry, im rushing a bit so you might have to paraphrase !

Answer:

Rosalie is correct, a line can have a line of symmetry.

Step-by-step explanation:

If you draw a line, a line of symmetry to that line would be perpendicular to the original line. Because lines are straight, they have an infinite number of lines of symmetry.

Answer:

30

Step-by-step explanation:

The sum of interior angles in this shape is equal to 360°

x + x + 5x + 5x = 360

12x = 360 divide both sides by 12

x = 30

Answer:

The coefficient of x represents the number of miles driven each day.

Step-by-step explanation:

The coefficient of x is being multiplied by x, or the number of days. If the expression models the total distance travelled, then Jeremy drove 450 miles each day.

Answer:

1.3

Substitutes

Step-by-step explanation:

Cross price elasticity,Edc = percentage change in Quantity demanded of D / percentage change in Price of C

Good C increases in price by 30 % a pound

Good D to increase by 40%

Cross price elasticity, Exy = percentage change in Quantity demanded of D / percentage change in Price of C

= 40% / 30%

= 1.333

To one decimal place = 1.3

When Edc > 0, Quanrity demand of good D and Price of good C

are directly related. D and C are substitutes

The goods are substitute

Answer:

the y-intercept is -14

Step-by-step explanation:

To get the y intercept, you need to get the b from y = mx + b

y - y₁ = m (x - x₁)

m = 4

(x₁,y₁) = (3,-2)

y - (-2) = (4) (x - (3))

y + 2 = 4x - 12

y + 2 - 2 = 4x - 12 - 2

y = 4x - 14

y = mx  + b

b = -14

Am I right?

Answer:

-18

Step-by-step explanation:

First, to find the y coordinate of the vertex, we need to find the x coordinate of the vertex.

The vertex will always be in the middle of the roots of the quadratic. The roots of the polynomial are 3 and 9, so the x coordinate of the vertex will be (3+9)/2 = 6.

Now that we know the x coordinate of the vertex, we can just plug in 6 for x to find the y coordinate:

2(6-3)(6-9)

=2(3)(-3)

=-18

Answer:

y=4x-2

you can find the y intercept if you plot a confirmed point on a graph and follow the slope to the line.

Answer:

y = 4x - 2

Step-by-step explanation:

Since we are given the slope already, we can solve for the y-intercept using the slope, the given point, and the formula [ y = mx + b ]

y = 4x + b

2 = 4(1) + b

2 = 4 + b

-2 = b

Substitute with what we solved for into the formula.

y = 4x - 2

The question is incomplete but it can still be solved.

To answer this question, I'll solve for the general formula which to determine Rico's donations

The given sequence shows an Arithmetic sequence; such that

[tex]First\ Term = T_1 = 125[/tex]

[tex]Common\ Difference = d = 143 - 125[/tex]

[tex]d = 18[/tex]

The general formula (Tn) is as follows:

[tex]T_n = T_1 +(n - 1)d[/tex]

Substitute values for T1 and d

[tex]T_n = 125 +(n - 1) * 18[/tex]

Open Bracket

[tex]T_n = 125 +18n - 18[/tex]

Collect Like Terms

[tex]T_n = 125 - 18+18n[/tex]

[tex]T_n = 107+18n[/tex]

Answer:

pentagons have five sides

Step-by-step explanation:

We want to find out why the statement disprove the conjecture

What the conjecture assumes is that for all polygons with more than 3 sides, all polygons here having their names ending in ‘gons’ have an even number of sides

The term pentagon refers to a 5-sided polygon

This polygon thus have more than 3 sides. Since 5 is not an even number, then we can conclude that the conjecture has been disproven

Answer:

its correct

Step-by-step explanation:

Each term of 6x^2+4x-9 is placed along the top of the table. Each term of 5x+1 is placed along the right side of the table.

We have 3 terms in 6x^2+4x-9 and 2 terms in 5x+1

So there are 3 columns and 2 rows leading to 3*2 = 6 cells total.

Each cell is filled in by multiplying the outer terms

For instance, row 1, column 1 has 6x^2*5x = (6*5)*(x^2*x) = 30x^3

The other cells are filled in the same way.

After the table is completed, you then combine like terms

20x^2 and 6x^2 is one pair which add to 26x^2

4x and -45x is another pair which add to -41x

The other terms are just added on, but not combined/simplified. This leads to the final answer shown on your paper.
