(-y2 – 4y - 8) – (-4y2 – 6y + 3)
Answers
Answer:
3y^2 +2y -11
Step-by-step explanation:
(-y^2 – 4y - 8) – (-4y^2 – 6y + 3)
Distribute the minus sign
(-y^2 – 4y - 8) +4y^2 + 6y - 3
Combine like terms
-y^2+4y^2 – 4y + 6y - 3-8
3y^2 +2y -11
Answer:
3y^2+2y-11
Step-by-step explanation:
I am guessing for -y2 and -4y2 you meant exponents; it would still get you the same answer though.
-y^2-4y-8 - (-4y2-6y+3)
1.Distribute; -y^2-4y-8 -1(-4y2*-1-6y*-1+3*-1)
you then get; -y^2+(-4y)+(-8) +4y^2+6y+-3
2.Combine like terms; 3y^2+2y-11
Then you get: 3y^2+2y-11.

y = 5(x² + 4x) - 16
y + 16 = 5(x² + 4x + __)
perfect square:
x² ⇒ x * x
4x ⇒ 2*2x
2² = 4
y + 16 + 4 = 5(x² + 4x + 4)
y + 20 = 5(x+2)²
(x+2)² ⇒ (x+2)(x+2) = x(x+2) + 2(x+2) = x² + 2x + 2x + 4 = x² + 4x + 4
y = 5(x+2)² - 20

143 is to the right of 134, it means that 143 is greater than 134.
To compare the numbers 134 and 143 using a number line, you can create a horizontal line and place the numbers on it. Here's a step-by-step explanation:
Create a Horizontal Line: Draw a horizontal line to represent the number line. You can imagine this line to represent different values as you move from left to right.
0 1 2 3 4
|---|---|---|---|
Position the Numbers: On this line, you will place the numbers 134 and 143 at their respective positions.
Place "134" on the number line by marking the position for each digit. The "1" is at position 1, the "3" is at position 3, and the "4" is at position 4.
0 1 2 3 4
|---|---|---|---|
1 3 4
Now, place "143" on the number line in a similar way. The "1" is at position 1, the "4" is at position 4, and the "3" is at position 3.
0 1 2 3 4
|---|---|---|---|
1 4 3
Compare the Positions: Now that you have both numbers on the number line, you can visually compare their positions.
You can see that the number 143 is to the right of 134 on the number line.
Determine the Result: Because 143 is to the right of 134, it means that 143 is greater than 134.
0 1 2 3 4
|---|---|---|---|
134 143

- - Why?
If you take the cost per person and for couples, you are adding them together.
Now you are going to multiply it by "x" because in this case, x is representing the number of people who actually bought the tickets.
Now you want to write a equal sign because you need it to solve up to $1200 (the cost you need to atleast get)
