Answer:
Step-by-step explanation:
-x + 2 = 3x + 6
3x + 6 = -x + 2
4x + 6 = 2
4x = -4
x = -1
y = 1 + 2 = 3
(-1, 3)
Let x=small circle
2x = bigger circle
πx^2 + π(2x)^2 = 80π
x^2 + 4x^2 = 80
5x^2 = 80
x^2 = 16
x = +/- 4
but we need the positive one because there's no negative measurement so
the answers are:
4m and 8m
The slope of a line parallel to another has the same slope: 2/3
The slope of a perpendicular line would be the opposite reciprocal: 3/2
Answer:
43
Step-by-step explanation:
180 - 43 = 137
then,
180 - 137 = 43
You can write an equivalent expression with this knowledge by taking a two numbers, and multiplying both of them by a number. You can extract the number by taking the gcf of both of them, and dividing them both by it and putting the numbers in a parenthesis and multiplying the numbers by the gcf.<span />
