Answer:
-6x + 22
Step-by-step explanation:
Note: This problem doesn't have a sign between 2 and 16, we would have to assume it is addition since 16 is 16 positive.
First we have to do distributive property,
-4 x 3x = -12x and -4 x -1 = 4
The equation should look like this:
-12x+4 + 6x + 2 + 16
Then combine like terms meaning do -12x + 6x
The answer should be -6x
The equation: -6x + 4 + 2 + 16
Then solve 4+2+16 which should equal 22
The answer: -6x + 22
Simplified!
Answer: The no fewer then sign would be <
Reason: let’s say that Alex wanted no fewer then 5 sheets of paper for a project. Alex can’t finish his assignment with only 4 sheets of paper. He can with 6, 7, 8, 9, etc. how we would label this is like this < 5 sheets. Think of the sign like a monster crocodile. It can eat as much as it can.
Answer:
The answer would be 39 campers.
Step-by-step explanation:
Think about before the 12 campers got off the bus. So, in addition to 27 campers that stayed inside the bus (12+27), it would equal 39 campers in total.
It’s H. You have to set up an equation: y=10x-11. -11 is the starting value, so you put it at the end. You add ten each time, so you put 10x. Just plug in 100 for x, and you’ll get 989
Answer:
- Find the coefficients using ax^2 + bx + c = 0
a = 4
b = 7
c = 0
- Make the coefficient equal 1. But how do we do that? Division.
4n² + 7n = 0
4/4n² + 7n/4 = 0/4
= n² + 7/4n = 0
a = 1
b = 7/4
c = 0
- Complete the square using b/2².
b = 7/4
(b/2)² = (7/4 ÷ 2)²
Use fraction rule.
7/4 ÷ 2² = 7/4² / 2²
<em>square the numbers</em>
7/4² / 2² = 49/16 ÷ 4
49/16 ÷ 4 = 49/16 × 1/4
49/16 × 1/4 = 49/64
Add to both sides of the equation using 49/64
b = 7/4
b/2 = 7/4 ÷ 2
<em>simplify</em>
b/2 = 7 ÷ (4 × 2)
<em>simplify(arithmetic)</em>
b/2 = 7/8
n² + 7/4n + 49/64 = 49/64
(n + 7/8)² = 49/64
Next, cancel out the square on the left side.
Subtract 7/8 from both of the sides.
Simplify the left side.
<em>That wraps it up for this equation. Hope it helped!</em>
