Hedi adds 5 to a number, then multiples the sum by negative 2. The result is 6. What is the number? *

Step-by-step explanation:

Let's say that the number is x. Hedi adds 5 to the number, then multiplies its sum by -2. The result is 6. Writing this out as an equation:

So now we solve for x. First, we divide both sides by -2, giving us:

Then, to finish the problem, we subtract 5 from both sides:

Thus, the number Hedi started with was -8

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
