Answer:
( 1/3, 5 2/3) Or (0.33, 5.66)
Step-by-step explanation:
If you graph the 2 equations and see where they intersect, they will land on the answer.
Answer: Your brother is 15 years old right now.
Step-by-step explanation:
Let be "m" your currently age and "b" your brother's currently age.
Knowing that right now he is three times (this indicates multiplication) as old as you, you can write the following equation:
In five years your age will be:
And your brother's age will be:
Then, if in five years, your brother will be twice as old as you, you can set up the second equation:
Then, the System of equations is:
Apply the Substitution method and substitute the first equation into the second one and solve for "m":
Substitute the value of "m" into the first equation and evaluate in order to find "b":
Answer: B) is the right answer→the distance between points a and b is equal to the distance between points b and c.
Step-by-step explanation:
As Kerry drew a number line starting at 0, point a, and ending at 1, point c and halfway between points a and c, he added point b.
.⇒ab=1/2 of ac and bc= 1/2 of ac or b is the mid point of line segment ac.
⇒ ab=bc(∵things which are equal to the same thing are equal to one another....→Euclid's first postulate)
Therefore, option B) the distance between points a and b is equal to the distance between points b and c is correct.
Answer: The correct point is (1, 0)
In polar coordinates, the first number is the distance from the origin in any direction. The second number is an angle measurement that tells us the direction to go from the origin.
Therefore, we have to move -1 one unit (or backwards) from the origin. Now, all we need to know is the direction to move.
The second number is 180, so we make an angle of 180 degrees and move in that direction.
But where do we start?
We always start from the origin straight right along the x-axis. That is degrees 0. So a 180 degree angle would move us left along the x-axis. But remember, we are moving back 1 space, so we will end up at (1, 0).
