Answer:
C
Step-by-step explanation:
A: Perpendicular lines have 1 solution. A is not the answer.
B: If the lines intersect, there is one solution, not many.
C: The lines are the same or can be reduced to being the same. C is the answer.
D: The lines don't intersect means that the lines are parallel. There isn't a solution.
y/3 = h
Multiply both sides by 3:
y = 3h
Answer:
(x+1)(2x+5)
Step-by-step explanation:
f(x) = 2x² + 7x + 5
Factor the expression by grouping. First, the expression needs to be rewritten as 2x²+ax+bx+5. To find a and b, set up a system to be solved.
a+b=7
ab=2×5=10
Since ab is positive, a and b have the same sign. Since a+b is positive, a and b are both positive. List all such integer pairs that give product 10.
1,10
2,5
Calculate the sum for each pair.
1+10=11
2+5=7
The solution is the pair that gives sum 7.
a=2
b=5
2x²+7x+5 as (2x²+2x)+(5x+5).
(2x²+2x)+(5x+5)
Factor out 2x in the first and 5 in the second group.
2x(x+1)+5(x+1)
Factor out common term x+1 by using distributive property.
(x+1)(2x+5)
You can use pythagorean theorem. 3 miles would be one leg and 2 miles would be the other. (We’ll just call these two a and b in the formula. Letter c, also known as your hypotenuse, will be this ‘straight line distance’.) In order to find this you’ll use: a^2 + b^2 = c^2
Then you’ll find the square root of your sum to get the answer.
Answer: 3^2 + 2^2 = ?
9 + 4 = 13
the square root of thirteen will be about
3.61
