GIven the equation LaTeX: y=\frac{2}{3}x-1y = 2 3 x − 1, determine the slope of the line.

Answers

Answer:

The general equation for a linear equation is

y is the y-coordinate

x is the x-coordinate

m is the gradient of the slope

c is where is passes through the y axis

So if you breakdown this equation () you are able to see that 2/3 is in the same spot as 'm' which is the gradient or slope of the line.

positive 2/3

Also if there was a negative infront of 'm' then the gradient would slope down '\' instead of up '/'

Step-by-step explanation:

The general equation for a linear equation is $y=mx+c$

y is the y-coordinate
x is the x-coordinate
m is the gradient of the slope
c is where is passes through the y axis

So if you breakdown this equation ( $y=(2)/(3) x-1$ ) you are able to see that 2/3 is in the same spot as 'm' which is the gradient or slope of the line.

Also if there was a negative infront of 'm' then the gradient would slope down '\' instead of up '/'

Please help me with this! Two children had 110 marbles between them. After one child had lost half her marbles and the other lost 20 they had an equal number. How many marbles did each child start with and how many did they finish with?

Answers

An equation is a mathematical statement that is made up of twoexpressions connected by an equalsign

x + y = 110

y - (1/2)x = 20

The number of marblesonechildren had is 50.

The number of marblesotherchildren had is 60.

What is an equation?

An equation is a mathematical statement that is made up of twoexpressions connected by an equalsign.

Example:

2x + 4y = 6 is an equation.

2x + 4 is an equation.

We have,

Totalnumber of marbles = 110

Number of children = 2

Number of marblesonechildren has initially = x

Number of marblesotherchildren has initially = y

Now,

x + y = 110 _____(1)

After one child had losthalf her marbles and the otherlost 20 they had an equalnumber.

This means,

x - (1/2)x = y - 20

(1/2)x = y - 20

y - (1/2)x = 20 _____(2)

From (1) and (2) we get,

x = 110 - y _____(3)

Putting (3) in (2)

y - (1/2)x = 20

y - (1/2)(110 - y) = 20

y - 55 + (1/2)y = 20

(3/2)y = 20 + 55

(3/2)y = 75

y = (75 x 2) / 3

y = 25 x 2

y = 50

Now,

Putting y = 50 in (3) we get,

x = 110 - y

x = 110 - 50

x = 60

Thus,

The number of marblesonechildren had is 50.

The number of marblesotherchildren had is 60.

Well both children has 110 marbles between them, and one child lost half and the other lost 20 so then it said they had an equal number so the other girl must had 20 so that makes 40 and 110-40= 80 so 80 is like the marbles that are left

i tryed my best to figure out what all of the numbers were. if i got any wrong then please tell me and i will put the right answer in the comments.

1) 3/5= 5/x (cross multiply)
3x=5(5)
3x=25
x= 25/3 -or- 8.33

2) 2/4=x/12   (cross multiply)
2(12)=4x
   24=4x
   6=x
3) 10/x=5/9   (cross multiply)
10(9)=5x
90=5x
18=x
4) 5/5=x/18   (cross multiply)
5(18)=18x
90=18x
5=x
