Answer:
the original price of the cooker is £320 and David has been a deposit of 15% so find 15% of the original price and the deposit is £48
Answer:
y = 2x - 3
Yes, your answer is correct.
Step-by-step explanation:
First, find the slope of the two points by using the slope formula:
y2 - y1
m = -------------
x2 - x1
13 - 5
m = -------------
8 - 4
8
m = ------- = 2
4
To find the y-intercept, plug in values into the slope-intercept formula:
y = mx + b
Where m = slope and b= y-intercept. Use any one of the points. I'll be using (4,5):
5 = (2) (4) + b
5 = 8 + b
-3 = b
b = -3
So, putting everything into the slope intercept formula:
y = 2x - 3
Alright, so let's make 2 3/5 into an improper fraction.
2 x 5 = 10 + 3 = 13
So 13/5 / 11/25.
Keep, change, flip rule: 13/5 x 25/11.
Now you multiple the numerator and denominator from both fractions. (I'm not going to do the math for you. Hope this helped and sorry if my explanation is...yeah.)
160 is 100% of 160, 480 is 4 times that. So 400%
