5 years. Because -15 - it's <span>changing at a rate per year.
75/15=5 years we need</span>
I think you have to figure out the gradient, so you take the 2 points and put it into the equation
change in y divided by change in x aka
y2-y1/x2-x1
so for question 3:
y2=4 and y1=3
(taken from the first and second coordinates)
x2=3 and y1=7
put these values jnto the equation
4-3/3-7 = 1/-4 (can be written as negative 1/4)
for question 4 its the same thing:
y2=9 and y1=5
x2=4 and x1=2
put into equation
9-5/4-2 = 4/2
hope this helps, im also hoping your teacher already has taught this because i didnt go into detail of where the equation came from, if not ask me and ill gladly help X
Answer:
liam
Step-by-step explanation:
We have, 25% × x = 150
or,
25
100
× x = 150
Multiplying both sides by 100 and dividing both sides by 25,
we have x = 150 ×
100
25
x = 600
If you are using a calculator, simply enter 150×100÷25, which will give you the answer.
Answer:
6. If the x intercept is a then (a,0) is on the line. If y-intercept is b then (0,b) is on the line. Now you have two points of the line and can get its formula. The slope between thse points is m=(0−b)(a−0)=−b/a. So the equation of line is y=mx+b=−bx/a+b. Now rearrange as y+bx/a=b divide by b to get y/b+x/a=1
