Answer:
The answer to your question is below
Step-by-step explanation:
Just cancel the parentheses and simplify
Result Addition
5xy² + 2x²y ⇒ (5xy² - x²y) + 3x²y = 5xy² + 2x²y
-3x²y - 2xy² ⇒ x²y + (-2xy² - 4x²y) = -3x²y - 2xy²
3x²y - 2xy² ⇒ 2x²y + (x²y - 2xy²) = 3x²y - 2xy²
5x²y + xy² ⇒ 4x²y + (x²y + xy²) = 5x²y + xy²
Answer:
B
Step-by-step explanation:
- Parabola that is opening upward has the form
- Parabola opening downward has the form
- Parabola opening leftward has the form
- Parabola opening rightward has the form
Where a is a constant
Now, looking at the graph given, it takes the form
Where a is 3 (matching the answer).
Hence, B is the correct answer choice.
Answer:
Step-by-step explanation:
The equation is:
√b+20 - √b = 5
The first step is we will add √b to both sides:
√b+20 -√b +√b = 5 +√b
√b+20 = 5+√b
Now take square at both sides:
(√b+20)^2 = (5+√b)^2
b+20 = 25+10√b+b
Now combine the like terms:
b+20-25-b=10√b
-5 = 10√b
Divide both the terms by 10
-5/10 = 10√b/10
-1/2=√b
Take square at both sides:
(-1/2)^2 = (√b)^2
1/4 = b
So in this type of question we add radical terms to both sides and square both sides twice....
Answer:6.4
Step-by-step explanation:
Column 1 Column 2
hiking 3
mountain biking 1.45
horseback riding 1.2
cross-country skiing 0.75
3+1.45+1.2+0.75=6.4
