Answer:
2 irrational solutions.
Step-by-step explanation:
6p^2 = 8p + 3
0 = -6p^2 + 8p + 3
The roots are:
p = (2/3) - (8.5)^(1/2)/3, and
p = (2/3) + (8.5)^(1/2)/3
These are irrational numbers.
There are 2 irrational solutions.
4(1.75y−3.5)+1.25y
. First multiply through with 4 the numbers in the parentheses.
7y➖ 14 ➕ 1.25y
add 1.25y to 7y
That will be 8.25y
So the answer will be 8.25y ➖ 14
-8x+9y=23 -- y=8/9x+23/9
(-4,-1), (1/2,3)
(3--1)/(1/2--4)= 4/(4 1/2)=.888888889
So answer A because if you rearrange it in y=mx+b form you see it's y=8/9x+23/9. And using the two points provided you can subtract to find the slope which comes out to be 8/9 the only two answers with that are A and B, so eliminate C and D. Then you can easily tell by looking at the graph that the y-intercept is positive, thus answer A is the only answer that works.
