I do not think all of the question is there.
25 X y = / y would have to
Step-by-step explanation:
X - 4 = 0
X = 4
X - 2 = 0
X = 2
So the values of x are 2 and 4
This is a linear equation y = mx, where:
m= slope or reading rate:
x = the number of minutes
y = the number of pages read.
So the equation becomes: y = 4.5.x
How many minutes it will take to read 90 pages (y):
90 = 4.5.x or x = 90/4.5 and x = 20 minutes
So the ordered pair will be (20,90)
When x=0, y=4...
Therefore:
4=a*b⁰
b⁰=1, so a=4.
----------
When x=1, y=2...
Therefore:
2=4*b¹
4b=2
b=2/4
So... b=1/2.
This means that:
y=4*((1/2)^x)
3/10:7/8=3/10*8/7=3*8/10*7=24/70=12/35
The answer is 12/35
