6x + 5y = 7
-6x - 9y = -9
-4y = -2
y = 1/2 or 0.5
2x + 3(1/2) = 3
2x + 1.5 = 3
2x = 1.5
x = 0.75
Hey there!
I just worked it out and the answer is D. 4y^2-10y-1
I’ve just studied these long equations and then having to simplify the expressions in algebra. I really hope my answer benefits you in the best way!

The next number in the sequence will be 12.
<em><u>Explanation</u></em>
The given sequence is: 8, 15, 14, 9, 1, 6, 3
If we express these numbers in words, then we can see that the words are in alphabetical order, like....
Eight, Fifteen, Fourteen, Nine, One, Six, Three
There are two numbers 10 and 12 in the options which starts with letter 'T' , but alphabetically '<u>Tw</u>elve' will be the next number after '<u>Th</u>ree'
So, the next number in the sequence will be 12.
Answer:
Step-by-step explanation:
1)
y = 5x-4 when x=5
y = 5*5-4
y = 25-4
y = 21
y = -2/5x + 3/8 when x = 1/3
y = -2/5 * 1/3 + 3/8
y = -2/15 + 3/8
y = -6/120
y = -1/20
y = 3x + 12 when x = 4
y = 3*4 + 12
y = 12 + 12
y = 24
