Three of the vertices of quadrilateral MARY are M (-3,1), A(3,3), and R(5,7). Find the
coordinates of Y, such that, quadrilateral MARY is a parallelogram.
Use coordinate geometry to prove that MARY is a parallelogram.
9514 1404 393
Answer:
Y = (-1, 5)
Step-by-step explanation:
The diagonals of a parallelogram bisect each other, so have the same midpoint. That is ...
(M +R)/2 = (A +Y)/2
Y = M + R - A . . . . . . multiply by 2 and subtract A
Y = (-3, 1) +(5, 7) -(3, 3) = (-3 +5 -3, 1 +7, -3) . . . . . substitute point coordinates
Y = (-1, 5)
Coordinate geometry was used to find Y that makes MARY a parallelogram. The fact that there is a solution is proof enough that MARY is a parallelogram.

showing opposite sides have the same slopeshowing opposite line segments have the same lengthGiven the method used above, both of these are unnecessary. However, in the interest of completeness, we will demonstrate.
Slope and Length of MA
slope = (3 -1)/(3 -(-3)) = 2/6 = 1/3
length = √(2²+6²) = √40
Slope and Length of AR
slope = (7 -3)/(5 -3) = 4/2 = 2
length = √(4² +2²) = √20
Slope and Length of RY
slope = (5 -7)/(-1 -5) = -2/-6 = 1/3 . . . . same as opposite side MA
length = √((-2)²+(-6)²) = √40 . . . . . . . same as opposite side MA
Slope and Length of YM
slope = (1 -5)/(-3 -(-1)) = -4/-2 = 2 . . . . same as opposite side AR
length = √((-4)² +(-2)²) = √20 . . . . . . same as opposite side AR
Opposite sides have the same slopes, so the figure is a parallelogram.
Opposite sides have the same lengths, so the figure is a parallelogram.

Skyler has twice as many apples in her grocery bag as her
friends Macy and Janelle combined. Macy has 15 apples
in her bag. Skyler has 50 apples in her bag. How
many apples does Janelle have in her grocery bag?

sequence of operations needed to solve this problem, using both arithmetic
and algebra?
A. Subtract 15 divide by 2 X = 35/2
B. Subtract by 15 divide by 2 X = 10
C. Divide by 2 subtract by 15 X = 10
D. Divide by 2 subtract by 15 X = 35/2

Solve. Express your answer as a mixed number. 5 feet= ______ yards Solve. I need an explanation on how to put it as a mixed number and how to solve it.
Answer: 5 feet= __5/3 0r 1 2/3____ yards
Step-by-step explanation:
Step 11 yard = 3 feet
3 feet = 1 yard
5 feet = 5feet x 1 yard/ 3feet
= 5/3yards
Step 2 To convert 5/3 yards to a mixed fraction,
1. We first Divide the numerator, 5 by the denominator, 3 giving us a whole number and a remainder
5/3 = 1 remainder 2
2.then we write the whole number and put the remainder 2 above the denominator 3 giving us
5/3 = 1 2/3
such that when you multiply the mixed fraction 3 x 1 and add 2 it gives back the improper fraction of 5/3
A pickup truck travels 45 Mi on 2 and 1/3 gallons and goes19 miles on one gallon of gas. At that rate how far will it travel on 4 1/4 gallons of gas?
work out the product 2 2/3 and 1 5/7
give the answer as a mixed number
Answer:
= 3 5/9
Step-by-step explanation:
2 2/3 × 1 5/7
= 8/3 × 12/7
= (8×12) / (3×7)
= 96/27
= 3 15/27
= 3 5/9
2 2/3 × 1 5/7 = 3 5/9
Solve the equation. y/8 = 5. y=
Answer:
y = 40
Step-by-step explanation:
Given
[tex]\frac{y}{8}[/tex] = 5 ( multiply both sides by 8 to clear the fraction )
y = 8 × 5 = 40
A wheel makes 35 revolutions per min. How many revolutions does it make per second?
The wheel makes revolutions per second.
(Type an integer or a simplified fraction.)
Answer:
7/12 revolutions per second
The wheel makes revolutions per second is 7/12.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given that, a wheel makes 35 revolutions per min.
Here,
35/1 minute × 1 minute/60 seconds
= 35/60
= 7/12 revolution per second
Therefore, the wheel makes revolutions per second is 7/12.

During swim practice Brand swim six butterfly stroke laps and eight freestyle Laps. What is the ratio of freestyle apps to total laps? A. 6:14 B. 8:6 C. 8:14 D. 14:8
Answer:
C) 8 : 14
Step-by-step explanation:
From the Question, we have
Six butterfly stroke laps
Eight freestyle Laps.
Total number of laps = (6 + 8)laps
= 14 laps
Hence,
The ratio of freestyle laps to total laps is:
Freestyle laps : Total laps
= 8 : 14
Option C is correct.
11. Find f(-1) for the function. f(x) = 3x - 4
Answer:
It is -7.
Step-by-step explanation:
Since x = -1, we can replace the x with -1 to get: -3 - 4 which is -7.
Answer: The answer is -7 for #11
Step-by-step explanation:f(x) = 3x - 4
f(x) = 3(-1) - 4 plug in -1 in x
-3-4 subtract both -3 and 4
-7 the answer

Answer:
2 1/2
Step-by-step explanation:
Answer:
2 1/2
Step-by-step explanation:
Since P is at -4 and you want a number that is 6 1/2 units away from it. You are either adding 6 1/2 to it or subtracting 6 1/2 to that number.
-4 + 6 1/2 = 2 1/2
-4 - 6 1/2 = -10 1/2
Also if you count 6 and 1/2 notches in either directions from -4, you will also get both of those answers.
The multiple choice only gives you the 2 1/2 option so that is the one they are looking for.

During a basketball game, Bari scored 28 points. During the same game, Denay scored 1/4 the number of points Bari scored. How many points did Denay scored during his basketball game?
Answer:
Denay scored 7 points during his basketball game.
Step-by-step explanation:
Given that,
Bari scored 28 points.
During the same game, Denay scored 1/4 the number of points Bari scored.
Denay scored = (1/4) × Bari scored
= (1/4)×28
= 7
Hence, Denay scored 7 points during his basketball game.
