Answer:
5.5
Step-by-step explanation:
3.5 is 1/2 of 7. GH is similar to ML. Half of ML is 5.5.
All you have to do is substitute in the x value into the equation.
y=10x
y=10(-3)
y=-30
The value of y when x is -3 is -30
Good luck!
Answer:
Y=2x+1
Step-by-step explanation:
The ad costs $2 per day(x) + the flat service of $1.
(1) day: $3=2(1)+1 (3) days: $9=2(3)+1
Answer:
15.86
Step-by-step explanation:
Answer:
y= -3x + 5
Step-by-step explanation:
Use the equation of a line formula:
y- y1 = m(x - x1)
where y1 and x1 are the y and x coordinates from the given point (1,2)
So y1= 2
x1= 1
And where m is the slope, -3
Plug in to get y-2 = -3(x-1)
Simplify and solve for y
y= -3(x-1)+2
y= -3x +3 +2
y = -3x + 5
