Answer:

9

Step-by-step explanation:

f(x) = 2x - 10

8 = 2x - 10

18 = 2x

9 = x

Best of Luck!

Answer:

see below

Step-by-step explanation:

f (x) = 2x – 10

Let f(x) = 8

8 = 2x-10

Add 10 to each side

8+10 =2x-10+10

18 =2x

Divide by 2

18/2 = 2x/2

9 =x

If you mean

f(8) = ?

Let x=8

f(8) = 2*8-10

    = 16-10

    = 6

f(8) = 6

Hi there!

An equation for this is:

-1/2x +4

Step-by-step explanation:

The slope is always in front of the "x"! The y intercept is always added to the slope!

Hope this helps

Answer:

y = -1/2x +4

Step-by-step explanation:

The slope intercept form of a line is given by

y = mx+b  where m is the slope and b is the y intercept

y = -1/2x +4

Answer:

Solve x2 - 16x + 60 = -12 by completing the steps.

First, subtract

60

from each side of the equation.

Next, add

64

to each side of the equation to complete the square.

Now, write x² - 16x + 64 = -8 as

✔ (x - 8)² = -8

Take the square root of both sides to get the solutions

8

Step-by-step explanation:

Answer:

8 ± 2i√2

Step-by-step explanation:

(x - 8)² = -8

√(x - 8)² = √(-8)

x - 8 = ±(2i√2)

x = 8 ± 2i√2

================================================

Work Shown:

m = 0 is the slope

b = -2 is the y intercept

y = mx+b

y = 0x+(-2)

y = 0x-2

y = 0-2

y = -2

This line is horizontal and goes through -2 on the y axis.

Two points on this line are (0,-2) and (1,-2)

Answer:

they answer would be y = 3x + 2

Step-by-step explanation:

Convert the equation to slope intercept form to get y = –1/3x + 2.  The old slope is –1/3 and the new slope is 3.  Perpendicular slopes must be opposite reciprocals of each other:  m1 * m2 = –1

With the new slope, use the slope intercept form and the point to calculate the intercept: y = mx + b or 5 = 3(1) + b, so b = 2

So y = 3x + 2

Answer:

Step-by-step explanation:

In order to solve this question we use ratio and proportion

From the question

y = 20 when x = 8

So we have

If y is 20 when x is 8

Then when y is - 2 x is

[tex] \frac{ - 2 \times 8}{20} = - \frac{16}{20} = - \frac{4}{5} \\ [/tex]

We have the final answer as

[tex]x = - \frac{4}{5} \\ [/tex]

Answer:

31x³-60x²+7x-75

Step-by-step explanation:

(30x³-49x³+7x)+(50x³-60x²-75)

(-19x³+7x)+(50x³-60x²-75)

-19x³+50x³+7x-60x²-75

31x³-60x²+7x-75

In the given figure QT is of 16 units.

A line segment has two end points unlike a line which can extend indefinitely in both the directions.

According to the given question S is between Q and T and R is the midpoint of QS. RS=4 And RT= 12 we have to find QT.

As R is the midpoint of QS It will be twice of RS which

= 8 units.

And if RS is 4 units then QR is also 4 unit as R is the midpoint.

QT = QR + RT.

QT = 4 + 12

QT = 16 units.

Answer:

Step-by-step explanation:

 let x be the no of miles

and y be the cost

cost of the first SUV

y=25535+0.18x-----1

cost of the second SUV

y=32395+0.13x------2

let us solve for x in equation 1 and 2

y=25535+0.18x-----1

y=32395+0.13x------2

subtraction 1 from

-y=-25535-0.18x

y=32395+0.13x

0=6860-0.05x

6860=0.05x

divide both sides by x

6860/0.05=x

x= 137200 miles

Answer:

x = ±2√3

Step-by-step explanation:

Step 1: Write equation

x² - 7 = 5

Step 2: Solve for x

Add 7 to both sides: x² = 12

Square root both sides: x = ±√12

Simplify: x = ±2√3

Step 3: Check

Plug in x to verify if it's a solution.

(2√3)² - 7 = 5

4(3) - 7 = 5

12 - 7 = 5

5 = 5

(-2√3)² - 7 = 5

4(3) - 7 = 5

12 - 7 = 5

5 = 5

Step-by-step explanation:

Answer:

A negative value or minus sign (-).

Step-by-step explanation:

A grouping symbol can be defined as a set of symbol used for organizing multiple numbers or variables in an algebraic equation.

In Mathematics, there are basically three (3) main grouping symbols and these are;

1. Parentheses ( ).

2. Braces { }.

3. Brackets [ ].

Additionally, grouping symbols are used to determine the order of operation when solving an algebraic equation.

Hence, when distributing a negative sign in front of grouping symbols, you must multiply each term inside the grouping symbols by a negative value or minus sign.

For example, given the algebraic equation X = 20 - 2(-1 + 2 - 5)

We would simplify the numbers in the parentheses (grouping symbol) by multiplying with -2;

X = 20 + 2 - 2 - 10

X = 20 - 10

X = 10

Example 2;

-(-1 - 2 + 3 - 4)

We multiply each term inside the grouping symbol by the minus sign

1 + 2 - 3 + 4 = 4.

Answer:

3.212*10^3

Step-by-step explanation:

you moved the decimal place 3 times

Scientific notations are the way through which a very small or a very large number can be written in shorthand. The height of angel falls, the tallest waterfall in the world in scientific notation is 3.212 × 10³ feet.

Scientific notations are the way through which a very small or a very large number can be written in shorthand.  In scientific notations when a number between 1 and 10s is multiplied by a power of 10.

For example, 6,500,000,000,000 can be written as 6.5e+12.

Given that the height of the angel falls is 3212 feet. Therefore, the height of the angel in the scientific notation is,

3212 feet

Multiply and divide the number by 1000, therefore, we can write,

= (3212/1000) × 1000 feet

= 3.212 × 1000 feet

= 3.212 × 10³ feet

Hence, the height of angel falls, the tallest waterfall in the world in scientific notation is 3.212 × 10³ feet.

Answer:

x is greater than or equal to -26

Step-by-step explanation:

We can use distributive property to solve the equation.

-6(x+4) in distributive property is:  -6x-24

-6x-24 is less than or equal to -5x+2

+6x                                             +6x

-24 is less than or equal to x+2

-2                                              -2

-26 is less than or equal to x

This means x is greater than or equal to -26

On the graph you would put a closed circle on -26 and point to the right.
