Slope intercept is almost the best for everything.
point slope is for when you only know the points on a line
standard form is for when solving systems of equations
Answer: the slope is 2/3.
Step-by-step explanation: The expression for finding slope when given 2 coordinates of the line is (y2 - y1) ÷ (x2 - x1) which just means that you take the y output of the second coordinate given to you and subtract the y output of the first coordinate given from that and the same for the x inputs. So when you plug in the numbers into that expression, you get (0- (-4)) ÷ (9 - 3). When you subract something from a negative number, its the same as adding. So it could also be written as (0 + 4) ÷ (9 - 3). When you subtract and add the numbers in both parentheses you end up with the fraction 4/6, but now you need to simplify that fraction which leaves you with the final answer of the fraction 2/3!
I hope this helps :)
Answer:
$1.20
Step-by-step explanation:
Ratio:
Grams : Kilograms
1 : .001
Multiply both sides by 20 to convert grams to kilograms:
Grams : Kilograms
1 : .001
x20 x20
20 : .02
This means that 20 grams of lead = .02 kilograms of lead
Price:
Cost : Kilogram
$60 : 1
Multiply both sides by .02 to find the price of the lead:
Cost : Kilogram
$60 : 1
x.02 x.02
$1.20 : .02
Therefore, .02 kg of lead costs $1.20.
Answer:
y = 400(1.01)^t
Step-by-step explanation:
Firstly find the rate
(Take any balance for two years, e. g 400 and 404,412.12 and 416.24,etc to get simple interest)
408.04-404= 4.04
I=(P*R*T)/100
From which R=(100*I)/PT
R= 100*4.04/404*1
R=1%
Using compound interest formula
A =P(1+r/100)^n
where n is time
substituting each value
y = 400(1+1/100)^t
y= 400(1.01)^t
