Answer:
y = 0.2x + 3.4
Step-by-step explanation:
Slope intercept form of line is
y = mx + c
where
m = slope
c is y intercept
given that slope is 0.2 thus, m = 0.2
now equation of line
y = 0.2x + c
now we substitute value of x and y ( (-2, 3) in this equation as given that the given point passes through the line
3 = 0.2*-2 + c
3 = -0.4 + c
c = 3+0.4 = 3.4
put c = 3.4 in equation
y = 0.2x + c
y = 0.2x + 3.4
Thus,
third option , y = 0.2x + 3.4 is the correct answer
The function is f(x)=2x+10
Answer:
-3
Step-by-step explanation:
since you have a fraction slope, we know that we would have to take the inverse reciprical of that to get -3!
-3 1/2 is rational because the decimal ends at -3.5. It is not sqrt(5) because the decimal never ends and the same follows for pi and 9.23157.
Answer:
Wasim has enough money.
Step-by-step explanation:
1. find the area of the garden path:
600 cm x 120 cm = 72,000 sq. cm
2. find the area of each stone:
it is a square of 30 cm by 30 cm, so:
30 cm x 30 cm = 900 sq. cm
3. find how many stones can fit in the path:
72,000 / 900 = 80 stones
4. multiply that by the price of each stone:
80 stones x $2.50 = $200
Wasim's budget is $220 and the stones will only cost $200, so it is within the budget
