This is algebra disguised as geometry. I object. There are much better ways to combine algebra and geometry.
Anyway, in a parallelogram the diagonals meet at their midpoints, so bisect each other. So we have two pairs of congruent segments; geometry over.
3x + 1 = x+27
79 - y = 2y + 22
We can ignore the one about x.
79 - 22 = 2y + y
57 = 3y
y = 19
Answer: 19
Answer:
Step-by-step explanation:
That is what she means! I don't know what you're asking but this may help the people that want to answer this question. :)
A) y= (-1/2)x+50
(y=(-1/2)4 +50 = -2+50= 48)
Y=( -1/2 )8-50=-4+50 =46
B) -1/2X+50>=40
-1/2X>= -10
X<=20
To start the meeting with 40 students it should be 20 minutes or less before the meeting
Draw the line with the zero in the middle
Draw a closed circle at +20 and from that point draw a line to the left
The percentage of questions she got correct is 88%
F(x) = x² + 4
y = x² + 4
First, I reverse the equation to be
x² + 4 = y
Second, we need only x to remain on the left side and we need to move the others to the right side
x² + 4 = y
x² = y - 4
x = √(y - 4)
Last, change into invers function
f⁻¹(x) = √(x - 4)
