Answer:
Slope is 1/4 (0.25) while y-intercept is 5
Step-by-step explanation:
Here, we are interested in getting the y intercept and slope of the line joining the given points.
We can get the slope by using any two points
Let’s say (4,6) and (12,8)
Mathematically; slope
= (y2-y1)/(x2-x1) = (8-6)/(12-4) = 2/8 = 1/4 = 0.25
To get the y-intercept, we proceed
kindly recall that the equation of a straight line is;
y = mx + c
where m is the slope and c is the y-intercept
Let’s take any of the points (28,12)
Thus:
12 = 0.25(28) + c
12 = 7 + c
c = 12-7
c = 5

Me preguntaba lo mismo. Desearía poder ayudar, pero también necesito ayuda.
Hmmm... a geometric sequence MUST have a fixed common ratio. If it is changing, then the sequence you are looking at might not be a geometric sequence at all. We'd need to see an example to be sure.
8/15 x 5/6
•multiply across the numerator and denominator.
= 40/90
• then find a common factor that will go into both the numerator and denominator equally.
Common factor: 5
= 8/18
•there is another common factor, which is 2
Simplified:
=4/9
<span>1. </span><span>Gaetano spent 37.80 dollars
including the tax for a pair of jeans
=> the tax is 8%, how much is the original cost of a pair of jeans?
=> 8% = 8/100
=> .08
Now, multiply .08 by 37.80 to get the 8% of 37.80
=> 37.80 x .08
=> 3.024 – this is the tax of a pair of jeans.
now, let’s subtract 3.024 by 37.80 to get the actual price of a pair of jeans.
=> 37.80 – 3.024
=> 34.776 – the original price of a pair of jeans without tax.
