3x -10+ 4x= -2 (x-4) +9

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:

x = 8

Step-by-step explanation:

Given the function x+25 = 33

Subtract 25 from both sides

x+25-25 = 33-25

x = 8

Hence the value of x is 8

Answer:

Multiply by 4 on both sides. 89.2 times 4 is 356.8. That is the answer. g = 356.8

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.

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:

4/6 - 3/6 equals 1/6

Step-by-step explanation:

Answer:

1/6

Step-by-step explanation:

2/3 - 1/2

First get a common denominator of 6

2/3 * 2/ 2= 4/6

1/2 *3/3 = 3/6

4/6 - 3/6

1/6

Answer:

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

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:

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:

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:

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

Answer:

Impossible

Step-by-step exp

Answer:

The answer is A.

Step-by-step explanation:

You have to apply Pythagoras Theorem :

[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]

[tex]let \: a = 20,b = 20[/tex]

[tex] {c}^{2} = {20}^{2} + {20}^{2} [/tex]

[tex] {c}^{2} = 800[/tex]

[tex]c = \sqrt{800} [/tex]

[tex]c = 28 \: (nearest \: whole \: no.)[/tex]

P.S (Take note):

Pythagoras Theorem can only applied in right angle triangle.

Answer:

We can find the hypotenuse by using the Pythagoras theorem/theory. The Pythagoras theorem states that,

[tex]h^{2}[/tex] = [tex]p^{2}[/tex] + [tex]b^{2}[/tex] where, h = hypotenuse, p = perpendicular, b = base

=> [tex]h^{2}[/tex] = [tex]20^{2}[/tex] + [tex]20^{2}[/tex]

=> [tex]h^{2}[/tex] = 400 + 400

=> [tex]h^{2}[/tex] = 800

=> h = [tex]\sqrt{800}[/tex]

=> h = 28.284.....

Therefore rounded to the nearest whole number, we get,

h = 28

Answer:

4x +y =5

Am I right?

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

(13/8, -5/4)

Step-by-step explanation:

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

4. C

5. D are the answers
