What is 3x+7x=9-18? Math is confusing once you get into 7th grade.

Answers

Answer 1

Answer:

x-(-0.9)

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation::3*x+7*x-(9-18)=0

Solve::10x+9 = 0

Subtract 9 from both sides of the equation::10x = -9

Divide both sides of the equation by 10::x = -9/10 = -0.900

Answer 2

Answer:

x = -0.9

Step-by-step explanation:

3x+7x=9-18

10x = -9

x = -9 / 10

x = -0.9

What are the points for y=-3x+4 and how do I graph it

Answers

Answer:

(-3,13) (-2,10) (-1,7) (0,4) (1,1) (2,-2) (3,5) (4,8)  are your graph points.

Step-by-step explanation:

Okay so to find the points, you have to create a table graph with a set of x values.

in this case, your equation y=-3x+4 the x can be replace with a set of numbers and these will be your plots.

-3(-3)+4= 13

-3(-2)+4= 10

-3(-1)+4= 7

-3(0)+4= 4

-3(1)+4= 1

-3(2)+4= -2

-3(3)+4= -5

-3(4)+4= -8

Naturally with these points a shape will form ideally a straight line. Hopefully this helps and good luck!

Item 6 Your city is represented in a coordinate plane where each unit represents 1 kilometer. The library is at (−3, −3), the post office is at (2, 2), and your house is at (−5, 2). You ride your bike from your house to the library, then the post office, and then back home. What is the minimum distance that you can ride your bike? Round your answer to the nearest tenth. km

Answers

We know, shortest distance between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is :

[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

So, distance between house and library is :

[tex]d_1=\sqrt{(-5-(-3))^2+(2-(-3))^2}\\\\d_1=5.39\ km[/tex]

Distance between library and post office :

[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\\\D=\sqrt{(-3-2)^2+(-3-2)^2}\\\\D=7.07\ km[/tex]

Distance between post office and house :

[tex]D=\sqrt{(2-(-5)^2)+(2-2)^2}\\\\D=7\ km[/tex]

Therefore, minimum distance that you can ride your bike is (5.39+7.07+7) km = 19.46  km.

Hence, this is the required solution.

Which of the binomials below is a factor of this trinomial?
5x2 + 20x + 15
O A. X-1
O B. X-5
O C. X+5
O D. x+1

Answers

The factor x + 1 is a factor of the trinomial expression 5x^2 + 20x + 15

How to determine the factor of the expression?

The expression is given as:

5x^2 + 20x + 15

Factor out 5 from the expression

5(x^2 + 4x + 3)

Expand

5(x^2 + x + 3x + 3)

Factorize the expression

5(x(x + 1) + 3(x + 1))

Factor out x + 1

5(x + 3)(x + 1)

The factors of the above expressions are 5, x + 3 and x + 1

Hence, x + 1 is a factor of the trinomial expression 5x^2 + 20x + 15

Point D is at the top in the pre-image and at the bottom in the image, so a vertical reflection is indicated. Only the 1st and 3rd choices show a reflection over the x-axis.

The image is to the left of the pre-image by 6 units, so the translation is in the negative direction. Only the 3rd choice has that.

What does x equal?

Answers

Answer: x = 9

We know that 26 and 17 are in a fact family.

Let's see the fact family.

26 - 17 = 9.

So, the answer is 9.

Hope this helps you!

Answer:

x = 9

Step-by-step explanation:

-x = 17 - 26                       Take the numbers to one side and leave the letters                                                       on the other side

-x = -9                                    Subtract the numbers

x = 9                       since the x and the 9 are negative they become positive

                              (two negatives equals a positive only when multiplying or

                               dividing and in this case you are dividing the -1x to both

                               sides)
