What are the solutions to this system of equations?
Answers
Answer:
( 3 , 0 ) ( 0 , − 6)a = 12 + 3y/ 16Step-by-step explanation:
Add 3 to both sides
16a-3y+3y=12+3y
Simplify
16a=12+3y
Divide both sides by 16
16a/16 = 12/16 + 3y/ 16
a= 12+ 3y/16

Answer:
BE=24
Angle EBC=33
Step-by-step explanation:
Rectangle diagonals are congruent so
[tex]3x + 6 = 6x - 12[/tex]
[tex]3x + 18 = 6x[/tex]
[tex]18 = 3x[/tex]
[tex]x = 6[/tex]
Plug that in one of the equations.
[tex]3(6) + 6 = 24[/tex]
BE=24.
ECD is apart of Isoceles triangle EDC.
Another isoceles triangle is EAB.
They triangle share two sides( remeber all diag ki bals in a rectangle are congruent) and a angle E, so they are congruent triangles.
That means Angle EBA measures 57 degrees.
Angle EBC and Angle EBA add up to 90 degrees so
Angle EBC=33

InO0, mCA=150andAB=CD
What is mBD?
Answers
Answer: I’m pretty sure that BD should also be 150
Step-by-step explanation:
The measure of angle O is 75 because the angle is always half of the arc, so knowing that, and also cd and abs are congruent, the other side of o is probably the same as the other, so it’d be 75, multiply by 2 and itll be 150.

Answer:
1.) the range is 42
2.) mean: 69.4, median:63, mode:none
3.) none since they are numbers that can be high but not low.
4.)The outlier is a greater number like the mean is 69 and the median is 63 which is halfway between 63 and 64 it will affect more the mean than the median since it doesn't matter the actual value of the outlier. it just depends on what the outlier is.
5.) the measure of central tendency best describes the set data with the outlier to which there is no outlier.

A coat has an original price of $48.99. Gloria wants to calculate the final cost of the coat including the 7% sales tax. She could use the expression 0.07 (48.99) + 48.99 to determine the final cost. Which other express could she also use to determine the final cost?
(0.07) ($48.99)
(1.07) ($48.99)
(1.93) ($48.99)
(0.93) ($48.99)
Answers
Ex
Since the first expression was
(0.07 x 48.99) + 48.99
Then multiply 0.07 by 48.99 =3.4293 + 48.99 = 52.4193
Try
1.(0.07)(48.99) =3.4293
2.(1.07)(48.99)=52.4193
3.(1.93)(48.99)= 94.5507
4.(0.93)(48.99)= 45.5607
The equation 2 was the only one that had the Sam answer as 52.4193
