Answer: okay.

Step-by-step explanation:

Answer:

First point we take the centre number

2[ 3x-y=11]

-1[ x+2y=6]

second we multiply and we adding

6x-2y=22

-x+-2y=-6

_________

5x/5=18/5

x= 3.4

Step-by-step explanation:

third point we take 3x-y=11 any x where we see we change 3.4

3(3.4)-y=11

10.2-y=11

y=10.2-11

y=0.8

Answer:

Yes

Step-by-step explanation:

Factoring is the process of breaking a polynomial into its factors.

Standard Form

It is easiest to factor when in standard form. Standard form is when the terms are listed from highest power to lowest.

Factoring

To find if two expressions are equal we can either factor the quadratic or multiply out the binomials. I find factoring to be faster and easier, so I will show that.

There are multiple techniques to factor; I will be explaining one of them. One way to factor quadratics is to find 2 numbers that multiply to c (the constant) and sum to b (the second term). In this case, the numbers -4 and -2 fit these requirements.

This means that [tex]x^2-6x+8[/tex] factored is [tex](x-4)(x-2)[/tex]. Thus, they are equivalent.

Answer:

Step-by-step explanation:

Let the equation of the line representing relation between the euros and dollars is,

E = mD + b

Where 'E' = Number of euros

D = Number of dollars

m = slope of the line

b = y-intercept

Slope of a line which passes through two points (120, 90) and (400, 300) will be,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] = [tex]\frac{300-90}{400-120}[/tex]

m = 0.75

Equation of the line passing through (120, 90),

90 = 0.75(120) + b

b = 90 - 90 = 0

Therefore, equation of the line will be,

E = mD

E ∝ D

Here m = Proportionality constant

And the relation between the numbers of Euros and US dollars is a proportional relationship.

Answer:

[tex]n-10=a[/tex]

Answer:

Mary is x years old

when we write the expression for her age which represents 12 years from now, it means we have to add 12 years in the age of Mary, and she is x years old now

so the expression will be:

x+12

and the expression which represents her age two years ago from now when she is x years old is:

x-2

if we know the x, we can calculate easily her age for above two expressions.

Step-by-step explanation:

[tex]\dfrac{(14+42-6)}{10}+7^2[/tex]

Parentheses (14 + 42 - 6) = 50:

⇒ 50/10 + 7²

Exponents 7² = 49:

⇒ 50/10 + 49

Multiplication/division  50/10 = 5:

⇒ 5 + 49

Addition/subtraction:  5 + 49 = 54

⇒ 54

Answer:

4/5

Step-by-step explanation:

Judging by the graph, it looks like there are 2 points at (0, 2) and (5, 6).

We can find the slope by 'subtracting' these points:

(6-2)/(5-0) =4/5

If you ever need to remember this trick, you can remember "rise over run".

Answer:

hamburger = h = $0.22

Fries = f = $0.96

Cola = c = $0.82

Step-by-step explanation:

Let

last year's price for each item be hamburger = h

Fries = f

Cola = c

h + f + c = 2.00 (1)

The price of a hamburger has increased by 10%

New price of hamburger = 1.10h

The price of fries has increased by 30%

New price of fries = 1.30f

The price of cola has increased by 40%

New price of cola = 1.40c

The same meal now costs $2.58.

1.1h + 1.3f + 1.4c = 2.58 (2)

If the price of a cola is now 9 cents more than that of a hamburger

1.4c = 1.1h + .09

1.4c - 1.1h = .09

Multiply (1) by 1.4

h + f + c = 2.00 × 1.4

1.4h + 1.4f + 1.4c = 2.8 (3)

1.1h + 1.3f + 1.4c = 2.58 (2)

subtract the new equation:

0.3h + 0.1f = 0.22

Multiply by 10

3h + f = 2.2

Recall,

1.4c - 1.1h = .09

1.4h + 1.4f + 1.4c = 2.8 (3)

- 1.1h + 0.0f + 1.4c = .09

Subtract

2.5h + 1.4f = 2.71

multiply by 10

25h + 14f = 27.1

Recall

3h + f = 2.2

Multiply by 14

42h + 14f = 30.8

25h + 14f = 27.1

Subtract to eliminate f

17h = 3.7

Divide both sides by 17

h = 3.7 / 17

= 0.22

h = 0.22

Substitute h into

1.4c - 1.1h = .09

1.4c - 1.1(0.22) = .09

1.4c - 0.242 = .09

1.4c = .09 + 0.242

1.4c = 1.142

Divide both sides by 1.4

c = 1.142 / 1.4

= 0.82

c = 0.82

Substitute values of c and h into

h + f + c = 2.00

0.22 + f + 0.82 = 2.00

1.04 + f = 2.00

f = 2.00 - 1.04

f = 0.96

Therefore, the price of each item last year was

hamburger = h = $0.22

Fries = f = $0.96

Cola = c = $0.82

Answer:

  -161.57°, or 198.43°

Step-by-step explanation:

The third-quadrant angle can be found using the usual rectangular-to-polar conversion. The angle is given by ...

  θ = ATAN2(x, y) = ATAN2(-12, -4) ≈ -161.57°

__

More conventionally, the reference angle is ...

  tan(θ) = y/x = -4/-12 = 1/3

  θ = arctan(1/3) ≈ 18.43° . . . . angle from -x axis (CCW)

Since this is a 3rd-quadrant angle, the positive angle value will be 180° plus the reference angle:

  180° +18.43° = 198.43°

The angle most directly measured from the +x axis is ...

  360° -198.43° = -161.57°

Answer:

[tex]ax^{2} +bx+c^{2}=0[/tex]

Step-by-step explanation:

A quadratic equation is a equation that takes the form: [tex]ax^{2} +bx+c^{2} = 0[/tex]

   Ex. Using our definition of quadratic equations, [tex]ax^{2} +bx+c^{2}=0[/tex],

          We can set a = 2, b = 1, c = 6:

               [tex]2x^{2} +x+6^{2}=0[/tex]

               [tex]2x^{2} +x+36=0[/tex]

          Which can then be solved (if you are trying to solve it) as:

               [tex](2x+9)(x-8)=0[/tex]

Answer:

3/8=0.375

Step-by-step explanation:

There are a total of 8 pairs and three of them are White. Its a simple fraction and figure out the decimal.

The amount of money I would repay in the first month is $166.67.

The amount of money I would repay in the second month is $166.67.

The amount of money I would repay in the third month is $166.66.

In order to determine the money that would be repaid each of the first two months, multiply 1/3 by the amount of the loan.

1/3 x $500 = $166.67

Amount to be repaid in the third month = $500 - (166.67 x 2) = $166.66

Answer: The midpoint is (5,5.5)

Step-by-step explanation:

Adding X1 And X2 equals 10. Then the x variables have to be divided which is 10 divided 2 equals 5, the 5 represents the x value of the x part of midpoint. (5,?)

Adding Y1 and Y2 equals 11. Then the y variables have to be divided by 2 which is 11 divided by 2 equals 5.5, the 5.5 represents the y value of the midpoint. (?,5.5)
