A property of a parallelogram is that their diagonals bisect eachother. Since in part a the diagonals bisect eachother, we know for sure that it's a parallelogram.
We also know that you can make two congruent triangles with a parallelogram. Note that if you draw a line from one accute angle to the other, we create two equal triangles by SAS congruency, so since the figure is comprised of two congruent triangles, it is a parallelogram.
Answer:
multiple choice is worth 2
short response is worth 4
Step-by-step explanation:
23x + 10y = 86
28x + 5y = 76
solve by elimination
multiply the top by -1 and the bottom by 2
-23x + -10y = -86
56x + 10y = 152
add them
33x = 66
x = 2
with x = 2 plug x into one of the equations
23x + 10y = 86
23(2) + 10y = 86
46 + 10y = 86
10y = 40
y = 4
x = 2 and y = 4 so
multiple choice is worth 2
short response is worth 4
Convert everything to whatever/24
4/24 + 6/24 + 8/24 = 18/24
simplify that to 3/4
so the answer is 1/4 because you do 1 - 3/4
(1 represents her total weekly allowance, 3/4 is the amount she used, so 1/4 is the amount she has left.)
Answer:
No I don't agree with Priya
The reason why I don't agree with Priya is because 25 Inch side blocks are BIGGER than 15 inch side blocks. That means that it will take less amount of 25 inch side blocks to fill up the volume of the rectangular prism rather than 15 inch side blocks.
(I'm sorry, I don't know what was your previous question, so I can't answer that part. If you comment it below, I will do it!)
The function has been reflected over the x-axis, and translated 6 units up (in the y-direction).
