Answer:
(0,10) and (2,4) and (3,1)
Step-by-step explanation:
All I did was substitute the x value
Have a great day!
:)
<span>the y-intercept will be
</span>the standard line equation is y = mx + b, where y is the y point, x is the x point, m is the slope, and b is the y-intercept.
to get the y intercept, we need to transform into the line equation, and caculate out b.
3x + 5y = 8
so 5y = 8 -3x
then y = <span>
- <span>
x
which means that <span>
= the y intercept.</span></span></span>
Let x be the value of the third term.
Since it's a geometric sequence, then:
Third term/Second term = Fourth term/Third term
x/20 = 11.25/x
Cross multiplication:
x^2 = 225
x = 15
So since the ratio is constant, then it is
x/20 = 15/20 = 3/4
So the common ratio is 3/4 or 0.75.
D.) x = 5, because when you plug five in for x, 5 + 5 = 10 is correct.
Yes you can write a ratio in more than one way
