Answer:
From least to greatest it is -5/2, -2, then 1.7
Step-by-step explanation:
First by process of elimination, 1.7 is the only positive number, so it is the greatest number compared to the other two.
Now we are left with -2 and -5/2.
We can rewrite -2 as , as any number by itself itself is the number over 1.
Then we need to find the common denominator for both fractions, meaning they must share the same bottom number.
The 1 in the denominator can be multiplied by 2 to get a denominator of 2 , the same as the denominator for .
Since the denominator is multiplied by 2, the numerator also has to be multiplied by 2:
Now since both fractions share the same denominator, we can compare them by their numerators. 5 is greater than 4, but we must keep in mind that these are negative. The larger the negative number, the smaller the value.
So when comparing -4/2 and -5/2, -5/2 is smaller.
So our final answer from least to greatest is -5/2, -2, then 1.7
Answer:
y +2 = 2(x +3)
Step-by-step explanation:
The equation in point-slope form for a line with slope m through point (h, k) is ...
y -k = m(x -h)
The slope of your given line is the coefficient of x, -1/2. The slope of a perpendicular line will be the negative reciprocal of that: -1/(-1/2) = 2. So, you have m = 2, (h, k) = (-3, -2), and your desired equation is ...
y -(-2) = 2(x -(-3)) . . . . . . which can be simplified to ...
y +2 = 2(x +3)
