Answer:
1) No
2) No
3) Yes
4)Yes
5) No
6) No
Step-by-step explanation:
In a function, no domains (x-coordinates) are repeated. Only graphs 3 and 4 meet this requirement.
Hope it helps!
Answer:
17 i think
Step-by-step explanation:
Answer:
1:c
let x be the distance
12^2=10^(2) + x^(2)
x=6.6332
2.D
length of 2->3 and 2->1 is 90ft, they are perpendicular
by using Pythagorus theorem
the diagonal of the square = square root of the sum of 90^2 +90^2
=127.279ft
3.B
12^2 -6^2 = 10.39ft
Step-by-step explanation:
Answer:
Algebra Review: x=-4, r =5
Step-by-step explanation:
Use distributive prop;
-3x-6=6
then add 6 to both sides to get x by itself
you get -3x=12
divide both sides by -3
you get x=-4
Again do distributive prop.
-12r+24=-36
trying to get r by itself, so subtract 24 on both sides
you get: -12r=-60
then divide -12 both sides to get r by itself and you get r=5
Pythageron Theorem:
which is a^2+b^2=c^2
a=3, b=7 and c=C^2 (this is always the long side)
so then we get 3^2+7^2=c^2
9+49=c^2
opposite of sqaring is rooting
so we get sqare root of 58 or 7.6
I'm sorry I can't help you with the angles, I would suggest looking it up and Khan Acadamy is a good resource. Good Luck!
Answer:
y = 5/4x
Step-by-step explanation:
To find the equation of the line, we'll have to find the slope only, since we already know that the equation is proportional and therefore has no y-intercept that we need to worry about.
So, to begin, we'll have to make a slope triangle using two of the points on the line - the points I chose are (0, 0) and (4, 5). Then, I drew a slope triangle - the change in y was 5, and the change in x was 4. To find the slope, we divide the change in y by the change in x, giving us a slope of 5/4. Because of this, our equation must be y = 5/4x.
Hopefully this is helpful! You can refer to the picture I attached if you would like to see how my slope triangle looks. :)
