Answer:
-7
Step-by-step explanation:
Because zero is the x, so x=-7 then it's -7
3 meters = 300 cm
300 cm + 35 cm = 335cm
Each cm is 10mm
So 335 cm = 3350 mm
Let x be the price of the breakfast.
We know that 20 percent of x is 1.80
Let's write this as a mathematical equation
0.2 x = 1.8
Let's divide both sides by 0.2 to isolate the x
x = 1.8 / 0.2
= 9
The price of the breakfast was $9.
Have an awesome day! :)
Answer:
y = 1/4x+1
Step-by-step explanation:
We have 2 points so we can find the slope
m = (y2-y1)/ (x2-x1)
= (1-2)/(0-4)
= -1/-4
= 1/4
The point (0,1) is the y intercept
We find the y intercept when x=0
We want to find the equation in slope intercept form
y= mx+b where m is the slope and b is the y intercept
y = 1/4x+1
Let x be the months and y be the cost.
Rate of increase of commodity A = 6/3 = $2 per month
Equation:
y = 2x + 4500
Rate of increase of commodity B = 2/4 = $0.5 per month
Equation:
y = 0.5x + 5400
Equating the costs,
2x + 4500 = 0.5x + 5400
1.5x = 900
x = 600 months
x = 600 / 12 = 50 years
