Answer:y = -3x + 10
Step-by-step explanation:
To find an equation of a line that passes through two points, we have to first find the slope between the two equation. We can do this by using the slope formula:
where (x₁, y₁) and (x₂, y₂) are the two points that we are finding the slope between.
Lets make (x₁, y₁) equal to (0, 10) and (x₂, y₂) equal to (3, 1). Now we plug them into the slope formula:
So the slope between the two points is -3.
From here, I would normally take one of the points given to us and plug in the point and slope into the point-slope form of a line and then simplify until we get it in slope-intercept form. But if you look carefully, the y-intercept is given to us as the point (0, 10). So we now know that the y-intercept of the line is 10. We can now take the y-intercept and the slope and plug it into the slope-intercept form of a line to get out equation:
y = mx + b
plug in -3 for m (the slope) and 10 for b (the y-intercept)
y = -3x + 10
So now we have our equation.
I hope you find my answer and explanation helpful. Happy studying. :)
Sry just add a triangle on each side took that test
So you have to decrease £30 by 20%
To do this, an easy way would be to first take away 100% from 20% because you are DECREASING :
100 - 20 = 80
Then divide your answer by 100 :
80 / 100 = 0.8
This means 0.8 is going to be your multiplier so you do
0.8 * 30 = 24
Answer = £24
V(cylinder)=πr² *h
r=8 cm
h=5 cm
V(cylinder)=πr² *h =3.14*8²*5= 1004.8 cm³
Answer : E.
Answer:
Monthly payment = $34.06
Finance charge = $343.87
Step-by-step explanation:
Given that:
Cost of silo = $2000
Down payment = 15% = (0.15) * 2000 = $300
Loan amount = $2000 - $300 = $1700
Period = 60 months = 5 years
APR = 7.5%
Using then monthly payment calculator, with the satiated parameters inputted :
The monthly payment is $34.06
The total amount paid over 60 months = $2,043.87
Therefore, finance charge = (total amount paid - loan amount)
$2043.87 - $1700
= $343.87
