Answer:
D
Step-by-step explanation:
We equate both the y's and solve for x algebraically:

Now taking the value x= 14 and putting it in the 1st equation would give us y:

Hence the solution is (14,8), answer is D
Answer: 2n^2+3n-4
1st differnce is 3, 7, 11, 15
2nd differnce is 4
so its 2n^2
we compare it to teh 2n^2 sequence
2 8 18 32 50
-1 2 9 20 35
difference is 3, 6, 9, 12,15
so it is 3n-4
Solve for one variable x or y first. So lets solve for x. If you take the first equation x= -12 -5y. You then plug that into the second equation
5(-12-5y) +4y = 24
now you solve for y
-60 - 25y + 4y =24
-21y=84
y=-4
Now you plug in y back into either equation and you get x=8
The y-intercept will be where it crosses the y-axis. The y-axis is the line that goes up and down also know a vertically.
Answer:
Step-by-step explanation:
The number is already defined as ' h '. "Twice" means times by 2. So, 13 and twice 'h' are being added together. Here 13 and h are to be added, and the answer is doubled.
