Lisa and conner had $360 altogether. After Connor gave Lisa 40% of his money, she had the same amount of money as he did. How mu

timama [110]

Answer:

Conner had 225 in the beginning

Step-by-step explanation:

Let lisa's money be L

and Conots money be C

C+L= 360----------------1

Connor gave Lisa 40% of his money,

L= 0.4C+L

C= 0.6C

L=0.4C+L=C

C=0.4C+L---------------2 <em>she had the same amount of money as he did</em>

C-0.4C=L

`0.6C=L

Put L=0.6C in eqn 1

C+0.6C= 360

1.6C= 360

C= 360/1.6

C=225

C+L= 360----------------1

225+L=360

L= 360-225

L= 135

Drag the point around to graph more horizontal lines. What is the general equation of a horizontalline?

svetlana [45]

A horizontal line is one for which the value of y is the same for the entire length of the line. Therefore this type of line can be expressed as below:

$y=c$

Where "c" is a constant that changes the position of the line on the coordinate plane. If c is equal to 2, then we have a constant line that crosses the y-axis at the position 2 for example.

Helppp!! 21 - 3y = -18<br> 3x+ y = -5

Ugo [173]

Answer:

(-3,4)

Step-by-step explanation:

A system of equations is given to us. The given equations are ,

$\implies 2x - 3y = -18$

$\implies 3x + y =-5$

We need to plot the graph and find the solution of the given system . For that refer to attachment . The point at which both the lines of the graph will intersect each other will be the solution of the given system of equations .

From the graph we can see that it intersect at (-3,4) . Therefore the Solution is ,

$\longrightarrow \underline{\underline{ Solution = (-3,4)}}$
