Answer:

9c + 5x + 3y + 13

Step-by-step explanation:

you can't combine any of the numbers wwith variables because the variables aren't the same but you can combine the other numbers (8, -2, 7)

8 - 2 = 6

6 + 7 = 13

put the equation back together but instead replace the 8, -2, and 7 with 13 giving you

9c + 5x + 3y +13

Answer:

x = - 5, y = - 9

Step-by-step explanation:

Given

x + 9i = - 5 - yi

For the 2 sides to be equal then the coefficients of like terms must be equal.

x = - 5 and 9 = - y ⇒ y = - 9

Answer:

X= Subtract 9 i from both sides of the equation.

Y= Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

x = − 5 − y i − 9 i

y = x i − 9 + 5 i

Answer:

we conclude that at x = -2 and x = -1, the value of f(x) = 2⁻ˣ  and g(x) = -2x is the same.

Therefore, the solution to f(x) = g(x) is:

x = -2

x = -1

Step-by-step explanation:

Given the table

x                f(x) = 2⁻ˣ                g(x) = -2x

-3                   8                                    6

-2                  4                                     4

-1                    2                                    2

0                    1                                     0

1                     1/2                                 -2

2                     1/4                                -4

3                     1/8                                -6

If we carefully observe, we can determine that

at x = -2, the value of f(x) = 2⁻ˣ  and g(x) = -2x is the same.

In other words,

at x = -2

Thus,

at x = -2

f(x) = g(x)

Also  at x = -1, the value of f(x) = 2⁻ˣ  and g(x) = -2x is the same.

In other words,

at x = -1

Thus,

at x = -1

f(x) = g(x)

Summary:

Thus, we conclude that at x = -2 and x = -1, the value of f(x) = 2⁻ˣ  and g(x) = -2x is the same.

Therefore, the solution to f(x) = g(x) is:

x = -2

x = -1

Answer:

The values of x which would give an area of 240m² would be:

[tex]x=-\frac{\sqrt{161}}{2},\:x=\frac{\sqrt{161}}{2}[/tex]

Step-by-step explanation:

Given

The base of triangle b = 2x+1

The height of triangle h = 6x-3

The Area of the triangle A = 240 m²

The Area of the triangle has the formula

A = 1/2 × b × h

substituting b = 2x+1, h = 6x-3 and A = 240

[tex]240\:=\:\frac{1}{2}\:\left(2x+1\right)\:\times \left(6x-3\right)[/tex]

[tex]480=\left(2x+1\right)\left(6x-3\right)[/tex]

[tex]480=12x^2-3[/tex]

Subtract 480 from both sides

[tex]12x^2-3-480=480-480[/tex]

[tex]12x^2-483=0[/tex]

[tex]3\left(4x^2-161\right)=0[/tex]

[tex]3\left(2x+\sqrt{161}\right)\left(2x-\sqrt{161}\right)=0[/tex]

Using the zero factor principle

if ab=0, then a=0 or b=0 (or both a=0 and b=0)

[tex]2x+\sqrt{161}=0\quad \mathrm{or}\quad \:2x-\sqrt{161}=0[/tex]

solving

[tex]2x+\sqrt{161}=0[/tex]

[tex]2x=-\sqrt{161}[/tex]

Divide both sides by 2

[tex]\frac{2x}{2}=\frac{-\sqrt{161}}{2}[/tex]

[tex]x=-\frac{\sqrt{161}}{2}[/tex]

also solving

[tex]2x-\sqrt{161}=0[/tex]

[tex]2x=\sqrt{161}[/tex]

Divide both sides by 2

[tex]\frac{2x}{2}=\frac{\sqrt{161}}{2}[/tex]

[tex]x=\frac{\sqrt{161}}{2}[/tex]

Therefore, the values of x which would give an area of 240m² would be:

[tex]x=-\frac{\sqrt{161}}{2},\:x=\frac{\sqrt{161}}{2}[/tex]

Answer:

x = 3 ± i [tex]\sqrt{3}[/tex]

Step-by-step explanation:

Given

x² - 6x + 12 = 0 ( subtract 12 from both sides )

x² - 6x = - 12

Using the method of completing the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 3)x + 9 = - 12 + 9

(x - 3)² = - 3 ( take the square root of both sides )

x - 3 = ± [tex]\sqrt{-3}[/tex] = ± i [tex]\sqrt{3}[/tex] ( add 3 to both sides )

x = 3 ± i [tex]\sqrt{3}[/tex]

Answer:  x = 300

Step-by-step explanation:

Answer:

Domain: [-8,inf)

Range: [-3,5]

Function: Yes

Step-by-step explanation:

First, this relation is a function because x's never repeat. The domain is every x-value that the graph covers, on this graph x's start at -8, which is included, and then continue forever. So the domain should be written as [-8,inf) because it is from least to greatest and the bracket shows -8 is included. The range is the y-values the graph covers. On this, the highest y is 5, and then the graph flattens at -3, both points are included. So the range must be [-3,5].

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The product of a positive and a negative integer is always negative.

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

Answer:

2.50 per pound

Step-by-step explanation:

The ratio of the price of oranges to the pound of oranges will be $0.40 per pound.

The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

Bebe paid $8.00 for 20 pounds of oranges. Then the ratio of the price of oranges to the pound of oranges will be given as,

Rate = $8 / 20

Rate = $0.40 per pound

The ratio of the price of oranges to the pound of oranges will be $0.40 per pound.

Answer:

45.650 centimeters

Step-by-step explanation:

The height of a vase is 45.7 centimeters when rounded to the nearest tenth of a centimeter. What is the shortest possible height of the vase? Give your answer to 3 decimal places

Given that :

Height of vase = 45.7 when rounded to the nearest tenth

The shortest possible height of the vase : will be 45.65, this is because, the subsequent digit (hundredth) after the tenth digit is the figure rounded to give a tenth digit of 7

From the we know that the tenth digit before rounding is 7 - 1 = 6

And smallest possible value the hundredth placed digit could have in other to be rounded to 1 is 5.

To three decimal place, the thousandth placed value could take the least possible value in a digit series, which is 0

Hence, the shortest possible height of the vase = 4.650

Answer:

f(x) = (x + 5)(x + 5)(x + 5)(x + 4)(x - 2)(x - 9)

Step-by-step explanation:

The polynomial function f(x) possessing a key coefficient of 1:

[tex](x+4)(x-2)(x-9)(x+5)^{3}[/tex] = 0

By opening the above equation;

f(x) = (x + 5)(x + 5)(x + 5)(x + 4)(x - 2)(x - 9)

∵ Thus, the above polynomial function makes the coefficient 1 with a multiplicity of 3 for root - 5 and 1 for -4, 2, and 9.

Step-by-step explanation:

3x-2y=12

-3x      -3x

-2y=-3x+12

y=3/2x-6

slope = 3/2

y-intercept = -6

Answer:

C) m=3/2 and b=-6

Step-by-step explanation:

The easiest way to do this is by converting the equation into slope-intercept form, which is written y=mx+b. So...

3x-2y=12     Subtract 3x from both sides.

-3x      -3x

-2y=-3x+12  Divide both sides by -2.

/-2   /-2

y=3/2x-6

The slope (m) is always right next to x, which, in this case, is 3/2.

The y-intercept (b) is the (simplified) regular number in the equation.

So, the correct answer is C) m=3/2 and b=-6.
