48 units! This may be wrong but hoped it helped!
Answer:
y = (ax)2
y = 2ax
divide both sides by 2a to make x the subject of the formula.
y/2a = 2ax/2a
x = y/ 2a
hope this was helpful,thanks
Answer:
Step-by-step explanation:
Let's Jiri's age be "J" and Pamela's age be "P".
P = 9 + J (Pamela is 9 years older than Jiri.) ... equation 1
P + J = 107 (the sum of their ages is 107) ... equation 2
Put equation 1 into equation 2:
(9+J) + J = 109
9 + 2J = 109
2J = 109 - 9
2J = 100
J = 100/2
J = 50
Therefore, Jiri's age is 50.
Perpendicular lines in equations are negative reciprocals of each other. If you multiply two slopes together and they equal -1, they are perpendicular.
3 * -1/3 = -1 so the slope is -1/3.
Equations that have the same slope are parallel. If another line had a slope = to 3, then the line would be parallel to y=3x-1
Answer:
Answer is (1): 2 times (x^2 -13)
Step-by-step explanation:
Using the FOIL method, you can conclude that (x-5)(x+5) is X^2 -5x +5x -25. Since the two middle terms cancel, you are left with X^2 -25. For the right side of the equation, (x-1)(x+1), using the FOIL method gets you x^2 -x +x -1. Once again, the -x and x cancel out and you end up with X^2 -1. To add both of these together, you can get rid of all parentheses and do the work. Two x^2 added together is 2X^2, and -25-1 is negative 26. After this, you end up with 2x^2 -26. To get to your final answer you need to take out the GCF of both terms, (the largest number that can go into 2x^2 and -26), which is 2. Taking the two out leaves us with 2(x^2 -13), which is your final answer. It looks like you were on the right track.
FOIL Property
Multiply first terms
Then Outside terms
Then inside terms
Then the last terms
