Answer:
The equation of the line is y = -5/2x + 25/2
Step-by-step explanation:
To find the equation of the line, we first need the slope. We can get that by using the slope formula.
m(slope) = (y2 - y1)/(x2 - x1)
m = (5 - 0)/(3 - 5)
m = (5)/(-2)
m = 5/-2
m = -5/2
Now that we have the slope, we use the slope and the given point in point-slope form. Then we solve for y.
y - y1 = m(x - x1)
y - 0 = -5/2(x - 5)
y = -5/2x + 25/2
Answer:
30
Step-by-step explanation:
You have to use the order of operations to solve this problem.
Steps:
1. solve the parenthesis first. 32/8=4
2. next is multiplication. 4.5(4)=18
3. lastly, do the addition. 18+12=30
I hope this helps.
Answer:
Step-by-step explanation:
Start by using the slope formula, which is :
y2 - y1 / x2 - x1
Now, get your two points and figure out which number will be your x1, x2, y1, and y1 values. (1,-3) will be your x1 and y1 values, because that point comes first in the question. (3,-5) will be your x2 and y2 values.
Put these values in the right order into your formula, like so,and then solve.
-5 - (-3) / 3 - 1
-5+3 / 2
-2 / 2
= -1
This is a slope of -1.
Answer:
25 years
Step-by-step explanation:
Given data
Principal P= $2000
Interest rate r= 6%
FInal amount A=$5,000
The simple interest formula is given as
A=P(1+rt)
substitute and solve for t
5000=2000(1+0.06*t)
5000=2000+120t
5000-2000=120t
3000=120t
t= 3000/120
t= 25 years
Hence, for a simple interest investment, she will be 25 years
