Since
simple interest = Pit
where
P=principal
i=interest rate
t=time,
we see that the equation is one of joint variation, meaning that simple interest is a direct variation with each variable, P, i or t.
Therefore if ANY one of the variables is doubled, the simple interest is also doubled.
Answer: I think it is B
Step-by-step explanation:
Half of 36 is 36/2
=18
1/7 of 42 is 42/7
=6
therefore, 1/7 of 42 is smaller
Answer:
y-3=3/5x
Step-by-step explanation:
y-y1=m(x-x1)
Where m=slope and (x1, y1) is a point on the line.
m=(y2-y1)/(x2-x1)
m=(0-3)/(-5-0)
m=-3/-5
m=3/5
y-3=3/5(x-0)
y-3=3/5(x)
y-3=3/5x
Answer:
The slope of the line that contains the points (-1, 2) and (4, 3) is:
Step-by-step explanation:
Given the points
Finding the slope between (-1, 2) and (4, 3)
![\left(x_1,\:y_1\right)=\left(-1,\:2\right),\:\left(x_2,\:y_2\right)=\left(4,\:3\right)](https://tex.z-dn.net/?f=%5Cleft%28x_1%2C%5C%3Ay_1%5Cright%29%3D%5Cleft%28-1%2C%5C%3A2%5Cright%29%2C%5C%3A%5Cleft%28x_2%2C%5C%3Ay_2%5Cright%29%3D%5Cleft%284%2C%5C%3A3%5Cright%29)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [3 - 2] / [4 - (-1)]
= 1 / 5
Thus, the slope of the line that contains the points (-1, 2) and (4, 3) is:
