2x(x+4)+7+=(x+8)+ 2x(x+1)+12=

Mathematics
1 answer:
Katena32 [7]3 years ago
8 0

Answer:

x=2.600

Step-by-step explanation:

2x(x+4)+7+=(x+8)+ 2x(x+1)+12

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

  ->        2*x*(x+4)+7+-((x+8)+2*x*(x+1)+12)=0

-> ((2x•(x+4))+7)-(((x+8)+2x•(x+1))+12)  = 0

->  (2x • (x + 4) +  7) -  (2x2 + 3x + 20)  = 0

->  5x - 13  = 0

-> Add  13  to both sides of the equation :  

                     5x = 13

Divide both sides of the equation by 5:

                    x = 13/5 = 2.600

During the summer Austin sells tomatoes at his family's produce stand . Every morning he starts with 150 tomatoes on. Sunday Aus
Marianna [84]

Answer:

30%

Step-by-step explanation:

Given:

Every morning he starts with 150 tomatoes.

On Sunday Austin sells 45 of the 150 tomatoes.

Question asked:

What percent of the tomatoes he sold ?

Solution:

As Austin sells 45 tomatoes out of 150 tomatoes, we will find percent of the tomatoes he sold by using :

Percent of the tomatoes he sold = Number of tomatoes he sold divided by total number of tomatoes he starts with.

Percentage =\frac{45}{150} \times100\\

                  =\frac{4500}{150} \\ = 30

Therefore, 30% of the tomatoes he sold on Sunday.

1/3x+2=3/4 how would I go about solving this???
Marizza181 [45]

Answer combine 1/2 and x.

X/2+2/3=1/6

Subtract 2/3 from both sides of the equation

X/2=1/6-2/3

Simplify the right side of the equation

-2/3 as a fraction with a common denominator, multiply by 2/2

X/2=1/6-2/3 x 2/2

Multiply 3 by 2

X/2 = 1/6 - 2/6 x 2

Combine the numerators over the common denominator

X/2 = 1-2 x2/ 6

Simplify the numerator

Multiply by -2 by 2

X/2 =1-4/6

Subtract 4 from 1

X/2= -3/6

Cancel the common factor of -3 and 6

Factor 3 out of -3

X/2 = 3(-1)/6

Cancel the common factor of 6

X/2 = 3 .-1/3.2

Rewrite the expression

X/2 = -1/2

Move the negative in front of the fraction

X/2= -1/2

Since both sides have the same Denominator the numerators must be equal.

X=-1

A line has an c intercept of 3 and a y intercept of negative 6. What is the slope intercept form of it’s equation
Schach [20]

Answer:

y = 2x - 6

Step-by-step explanation:

Slope-intercept form is  y = mx + b, where m is the slope and b is the y-intercept.

The y-intercept is already given and is -6.

By c intercept, I am assuming you meant x-intercept.  With an x-intercept of 3, the point is (3,0).  With a y-intercept of -6, the point is (0,-6).

Use the two points to find the slope using the following equation.

m=\frac{y_{2}-y_{1}  }{x_{2}- x_{1} }

Plug the points into their respective positions and solve.

m=\frac{-6-0}{0-3}\\ m=\frac{-6}{-3} \\m=2

The slope is 2.

Your equation is  y = 2x - 6.
