What is 49 increased by twice a number

1 answer:

4 0

49+2x
Increase means “go up” which is another way to say addition
Twice means “two times” or “doubled”
A number would be a variable since it’s unknown

Hopefully this helps...

I need an answer asap!!

Answer:

y = -3/2x + b

Step-by-step explanation:

To find slope intercept you take the amount it goes up or down over the amount left of right, the 2 closest points i found were 0,3 and 2,0

so it goes down 3 (-3) and right 2 (2)

so y = -3/2x + b

b = wherever it intercepts the y axis (0,3)

y = -3/2x + b
