What is the slope of the line on the graph?

Bogdan [553]

Answer:

m=-2

Step-by-step explanation:

Take 2 points (0,0) and (-3,6)

m(slope)= m = rise/run = y2 - y1/ x2 - x1

y2-y1= 6-0=6

x2-x1 = -3-0 = -3

m=6/-3 = -2

y=-2x

£880 is divided between Jim, Krutika & Natasha so that Jim gets twice as much as Krutika, and Krutika gets three times as mu

krok68 [10]

Answer:

264 pounds

Step-by-step explanation:

Write the question in the form of a ratio:

Natasha: Krutika: Jim

1:3:6

Now, we divide the amount of 880 in the ratio.

there are 10 parts in total.

1 part = 880 divided by 10 = 88.

since Krutika gets 3 parts, she gets 88 x 3 = 264

Solve the system by substitution. 4x+3y=5x=4y+6Options: A. The solution is ____B. There are infinitely many solutions. C. There

zvonat [6]

So we have the following system of equations:

$\begin{gathered} 4x+3y=5 \\ x=4y+6 \end{gathered}$

We need to solve it by substitution. This means that we have to take the expression for x given by the second equation and replace x with it in the first equation:

$\begin{gathered} 4x+3y=5 \\ 4\cdot(4y+6)+3y=5 \\ 16y+24+3y=5 \\ 16y+3y=5-24 \\ 19y=-19 \\ y=-\frac{19}{19}=-1 \end{gathered}$

So y=-1. If we use this value in the second equation:

$\begin{gathered} x=4y+6 \\ x=4\cdot(-1)+6 \\ x=-4+6 \\ x=2 \end{gathered}$

So we have x=2 and y=-1 which means that there's one solution. Then the correct answer is A and the solution is (2,-1).
