Answer:

10x.............

Step-by-step explanation:

or x=10

Answer:

x = 14

Step-by-step explanation:

Okay so the equation looks like this:

X/-2 = -7

In order for us to get rid of the -2 we are going to have to multiply -2 on both sides of the equal sign, so that we only have x on one side of the equal sign and numbers on the other:

X/-2 = -7

 *-2  *-2

since multiplying or dividing a negative number by a negative number gives you a positive -7 is going to become 14 and x remains on the other side of the equal sign:

x = 14

Now to check our work we are going to place 14 where the x variable is in the equation:

X/-2 = -7 or (14)/-2 = -7

-7 = -7

Hope this helps you!!

20x+160=10x+200

20x-10x=200-160

10x=40

x=4

Answer:

(final - initial/initial ) * 100

66 - 55/55 * 100

11/55 * 100

100/5

= 20 percent

Answer: (x, y) = (10, 10)

Since x = y, replacing y with x in 6x - 3y = 30 we have 6x - 3x = 3x = 30, so x = 30/3 = 10. Then y = x = 10, so the solution is (10, 10).

Answer:

5.7 hours

Step-by-step explanation:

average speed = distance / time

rewriting gives

time = distance / average speed.

distance = 320 km

average speed = 56 km/hour

so

time = 320 / 56 = 5.7 hours

Use ur calculator

Answer:

Use the Substitution method to solve this system of equations:

.

x=-y-1

x-y=-11

.

Substitute -y-1 for x in the second equation. (We can make this move because the first equation tells us that whatever x is, it is equal to -y-1.)

.

x-y=-11

%28-y-1%29-y=-11

.

Simplify by combining like terms.

-2y-1=-11

-2y=-10

y=5

.

Substitute 5 for y in the first equation.

x=-y-1

x=-%285%29-1

Answer:

I will say this idk if you learn by reading or watching better, so if it's reading then read on! but if it's watching then look up "how to graph lines" and there is a bunch of videos!

Step-by-step explanation:

so you have y = 3x - 2 so first on the y axis your start point will be (0, -2)

then refer to rise over run ( rise/run) where rise is up(on the y axis) and run is across on the x axis.

so you start at (o, -2) and up 3 points on the y axis and across 1 point (go left) and mark it and repeat( up 3 across 1) until you reach  the top of the graph

then finish the graph so repeating this going to the bottom is the same but different directions:

so go back to (0, -2) and go down 3 points (y axis) and across 1 point(this time go right on the x axis) and repeat until you reach the bottom and then use the points you marked to trace a line and boom your done! (this explanation is only for number 10)

same rise over run but different points and possibly line direction.

so for number 11: your starting point is (0, 3) and you go up 4 point and across 1 point but this time go across to the right. repeat. once you at the top of the graph go back to (0, 3) and go down 4 points and 1 point to the left. repeat. until you reach the bottom. trace the line.

number 12: a bit more tricky. starting point  is (0, 5) for this one you go up 6 points and across 5 to the right. repeat. until you get to the top then go back to (0, 5) and go down 6 points and across 5 to the left. repeat. once you reach the bottom trace your line. then done! Sorry to inform you I don't know about 13 and 14! :(

Bonus but still important: the reason why you are going left and right on some of the lines is because the + or - in your equations tell you which direction the line is facing, toward the left (on the top part of your graph) would be - and toward the right part of your would be a + in the equation

More Bonus: a formula Is y=mx + b (0, b)( for ex: 0,5) is the starting point and (mx or for ex 4x is the amount you go up and across. When there is a x that always means across 1 and when there is not a x (ex: 6/5) it's across whatever the 5 is. ex: 6/6 is up 6 and across 6

Hope this helps!

Answer:

2

to find the slope you get the rise which is the difference between the y coordinates over the run which is the difference between the x coordinates. so 6/3=2

Answer:

(3, 1 )

Step-by-step explanation:

Given the 2 equations

y = - x + 4 → (1)

y = x - 2 → (2)

Substitute y = x - 2 into (1)

x - 2 = - x + 4 ( add x to both sides )

2x - 2 = 4 ( add 2 to both sides )

2x = 6 ( divide both sides by 2 )

x = 3

Substitute x = 3 into either of the 2 equations and solve for y

Substituting into (2)

y = 3 - 2 = 1

solution is (3, 1 )

Answer:

25 - 3x = 40            ​x=-5

1/3x - 12 = -3           x=27

Step-by-step explanation:

25-3x=40 -> subtract 25 each side .... -3x=15 -> divide -3 each side...... x= -5

Answer:

C. 67%

Step-by-step explanation:

First, find the total amount of people that voted:

80 + 160

= 240

To find the percent of students that voted for a bulldog, divide 160 by 240:

160/240

= 0.66

So, this is approximately 67%. C is the correct answer

Answer:

El recíproco o inverso multiplicativo de un número x es el número que, cuando es multiplicado por x , da 1. ... (Esto es algunas veces llamada la propiedad de los recíprocos .) Ejemplo 1: así el recíproco de 3 es (y el recíproco de es 3.)

Answer:

D. (4,7)

E. (0,1)

Step-by-step

See screenshot of graph and points.  

When y = 46 , x=4

23(4)=46x

(92)\46=x

X=2

The value of x will be 2 when y = 23.

the property of having suitable proportions in terms of size, number, degree, harshness, etc.: If a defensive action against an unfair attack results in the destruction that contravenes the proportionality criterion, it may even go far beyond a justifiable defense.

Given,  y is directly proportional to ​x​ , and ​y​ = 46 when ​x​ = 4,

Thus,

x : y = 4 : 46

x : y = 2: 23

So, in reference

x = 2y/23

so at y = 23 the value of x will be,

x = 2*23/23

x = 2

therefore, The value of x will be 2 when y = 23.
