2/7(x+4)=−6 What is x?

Answer:

The answer is

Step-by-step explanation:

2x² = - x² - 5x - 1

Rearrange the terms and simplify

That's

2x² + x² + 5x + 1 = 0

3x² + 5x + 1 = 0

Using the quadratic formula solve the equation

That's

From the question

a = 3 , b = 5 , c = 1

So we have

Answer: ITS C!!!!!!!

Step-by-step explanation:

Answer:

-2[h(3)] = 0

Step-by-step explanation:

Step 1: Define

h(x) = 2x - 6

Step 2: Find h(3)

h(3) = 2(3) - 6

h(3) = 6 - 6

h(3) = 0

Step 3: Find -2[h(3)]

-2(0)

0

infinite solutions cuz 0=6

Step-by-step explanation:

subtract the pay to the additional pay

Answer:

The answer is x>17

Step-by-step explanation:

First subtract 4x from both sides

6x - 8 > 4x + 26

-4x. -4x

2x - 8 > 26

8 is negative so to get rid of it add 8 to -8 and 26

2x - 8 > 26

+8. +8

2x > 34

x needs to be by itself so divide both sides by 2

2x > 34

2. 2

x > 17

Step-by-step explanation:

Ordered pairs are like  represented by the x and y variables, where x  is the x coordinate and y is  y coordinate. In this situation, C  represents y and f represents x.

Step-by-step explanation:

Since there are in arithmetic progression, 2(2x + 9) = (3x + k) + (x + 13).

=> 4x + 18 = 4x + 13 + k

Hence k = 5.

Answer:

3.5 miles

Step-by-step explanation:

From the question, we have the following information:

The super speedway at Daytona International Speedway is = 2.5 miles

long

The road course there is = 1.4 times as long as the super speedway.

How long is the road course?

The length of the road course is calculated as:

1.4 × length of the super speedway

1.4 × 2.5 miles

=>3.5 miles

Therefore, length of the road course I s 3.5 miles.

The multiplication equation represented by the model is 5 x 3.

Multiplication is the process of determining the product of two or more numbers in mathematics. A product, or an expression that specifies factors to be multiplied, is what happens when you multiply two numbers in mathematics.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

The model has 5 rows and 3 columns shaded. The multiplication equation will be written below,

Multiplication equation = 5 x 3

Answer:

1:2

Just remember for that ratio, it is 1 to 2. the second number is double the first.

Answer:

1/2

Step-by-step explanation:

To make this a equal fraction we have to make the denominator(the bottom) the same

So the fraction would be multiplied by 2 = 10/6

Now we add 10/6 by -7/6

This is the same thing as 10/6 - 7/6 which is 3/6

Now we simplify 3/6. 1/2

Answer: x = − 10

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (8, - 3) and (x₂, y₂ ) = (2, 6)

m = [tex]\frac{6+3}{2-8}[/tex] = [tex]\frac{9}{-6}[/tex] = - [tex]\frac{3}{2}[/tex]

------------------------------------------

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

y = 5 - 2x , that is

y = - 2x + 5 ← in slope- intercept form

Answer:

The pattern = 1³, 2³ 3³, 4³, 5³, 6³, 7³, 8³, 9³,

The answer = 1, 8, 27, 64, 125, 216, 343, 512, 729,

Step-by-step explanation:

what is the pattern?

We are given the following sequence:

1, 8, 27, 64, __, __, __, __, __,

Observing the sequence above, for every consecutive natural number

x, x + 1, x + 2, x + 3.......

The above pattern is : the cube of every consecutive natural number. That is: x³, (x + 1)³, (x + 2)³, (x + 3)⁴

1, 8, 27, 64, __, __, __, __, __,

= 1³, 2³ 3³, 4³, 5³, 6³, 7³, 8³, 9³,

Hence, the answer

1, 8, 27, 64, 125, 216, 343, 512, 729,

Step-by-step explanation:

The function is positive when the graph is over the x-axis, and negative when the graph is under the x-axis.

As we can see from the graph, it has x-intercepts at x = -3 and x = 3.

Since the graph curves upwards, the function is positive in intervals (-∞, -3) U (3, ∞) and negative in the interval (-3, 3).

Step-by-step explanation:

Let's solve your equation step-by-step.

3(x+1)=−1(x−1)−4

Step 1: Simplify both sides of the equation.

3(x+1)=−1(x−1)−4

(3)(x)+(3)(1)=(−1)(x)+(−1)(−1)+−4(Distribute)

3x+3=−x+1+−4

3x+3=(−x)+(1+−4)(Combine Like Terms)

3x+3=−x+−3

3x+3=−x−3

Step 2: Add x to both sides.

3x+3+x=−x−3+x

4x+3=−3

Step 3: Subtract 3 from both sides.

4x+3−3=−3−3

4x=−6

Step 4: Divide both sides by 4.
