(I) To solve for the midpoint of two points `(x_1, y_1)` and `(x_2, y_2)` , use the formula: `x_(mid)=(x_2+x_1)/2` `y_(mid)=(y_2+y_1)/2` And to solve for the distance between two point, apply the formula: `d=sqrt((x_2-x_1)^2+(y_2-y_1)^2)` (1) A(2,-5), B(6, -7) `x_(mid)=(6+2)/2=8/2=4` `y_(mid)=(-7+(-5))/2=(-12)/2=-6` `d=sqrt((6-2)^2+(-7-(-5))^2)=sqrt(4^2+(-2)^2)=sqrt(20) = 2sqrt5` Hence, the midpoint of these two points is (4,-6) and their...http://www.enotes.com/homework-help/find-midpoint-b-distance-each-line-segment-ab-with-471061Tue, 16 Sep 2014 02:04:23 PSTThe midpoint between two points (a,b) and (c,d) is given by...

The midpoint between two points (a,b) and (c,d) is given by `((a+c)/2, (b+d)/2)` We have that one point is (2,8). So we can let a=2 and b=8. We also know the midpoint is (4,9). From this information we get the following (4,9) =`((2+c)/2,(8+d)/2)` Since two points are equal only if both coordinates are equal we have: To solve the second equation, multiply both sides by 2. This gives you 8 = 2+c. Subtract 2 from both sides to find 6...http://www.enotes.com/homework-help/midpoint-m-ab-has-coordinates-4-9-coordinates-2-8-471062Tue, 16 Sep 2014 01:07:35 PSTSince M is the midpoint of a linear segment, then by definition the...

Since M is the midpoint of a linear segment, then by definition the segment from A to M will have the same slope as the segment from M to B. If we find the slope of AM, and apply it to M, it will lead us to B. Comparing M and A, we find that there is a +2 change in X, and a +1 change in Y. All we need to do is apply these changes to the coordinates of M; 4(+2), 9(+1) B = 6,10http://www.enotes.com/homework-help/midpoint-m-ab-has-coordinates-4-9-coordinates-2-8-471062#1Tue, 16 Sep 2014 00:18:38 PSTThe midpoint M of AB has coordinates (4,9).

JK = x^2 - 4x KL = 3x - 2 JL = 28 With the information given, you can conclude that JK and KL are both collinear segments, meaning they pass through the same straight line (JL). Therefore, you can conclude that JL is equal to the combined equations of JK and KL. JL = x^2 - 4x + 3x - 2 JL = x^2 - x - 2 = 28 You can make this equation be a quadratic by subtracting 28 from both sides. x^2 - x - 30 = 0 Now you are able to solve for x using the...http://www.enotes.com/homework-help/jk-equal-x-squared-4x-kl-equal-3x-2-jl-28-how-do-471043Mon, 15 Sep 2014 22:48:42 PST59 x 2 = 118.

59 x 2 = 118. There re several ways you can solve this problem, the easiest being a calculator, but if you want an explanation about what multiplying by two is, it is basically adding 59 to 59. When you multiply by the number two you are essentially solving 59 + 59, which also gives you 118.http://www.enotes.com/homework-help/what-59x2-471049Mon, 15 Sep 2014 22:39:16 PSTDecimals can be thought of as the calculated form of a ratio, i.e. a...

Decimals can be thought of as the calculated form of a ratio, i.e. a fraction. For example: .5 is just another way of saying 1:2, or 1/2 Put in mathematical terms: `0.5 = 1/2 ` If we multiply both sides by the fraction's denominator, we get the numerator. 2 x (0.5) = 1 So: Denominator x Decimal form = Numerator We need to find the Denominator and Numerator; our only clue is that these will be integers. What we need to do is multiply the...http://www.enotes.com/homework-help/how-write-number-3-571428-ratio-two-integers-471058Mon, 15 Sep 2014 21:56:33 PSTHow can the number 3.571428 be written as a ratio of two integers?

There's multiple ways to solve 59 x 2 that could help you in the future. First off 59 x 2 means 59 + 59 = 118 A second way is 29.5 + 29.5 + 29.5 + 29.5 = 118 You can always simplify out the 59 in multiple ways. Taking the 59 into 50 and 9. 50+9+50+9, which also means 2[50 + 9]. If you know simple multiplication you'll get this easily. 2 times 50 would have to be 100. 2 times 9 would have to be 18 100 + 18 = 118. You can do a lot of form of...http://www.enotes.com/homework-help/what-59x2-471049#5Mon, 15 Sep 2014 14:55:10 PST59x2=118

59x2= 118 Here are some ways to perform this calculation: 2(50+9)=2(50)+2(9)=100+18=118 2(60-1)=2(60)-2(1)=120-2=118 The standard algorithm is to multiply 2x9 getting 18; write the 8 and "carry" the 1. Then when you multiply 5x2 to get 10, you add the carried 1 to get 11. Then the answer is 118:159 2--118 Last, we can multiply the ones digit times 2 to get 18. Then we multiply the tens digit by 2 to get 10. 10 tens is 100; 100+18=118.http://www.enotes.com/homework-help/what-59x2-471049#7Mon, 15 Sep 2014 03:30:47 PSTWhat is 59x2
