Answer:
You got the fourth and fifth question wrong.
Step-by-step explanation:
FOR QUESTION 4, You put 3/1 x 3/4 = 9/4.
7/1 x 3/4 = 21/4, or 5 1/4
FOR QUESTION 5, You put 4 3/4 x 62= 48/What number is unclear. ANYWAY
4 3/4x 62 = 19/4 x 62/1 = 1178/4, or 294 2/4.

Only (a) describes a one-to-one function. (b) fails because
; similarly, (c) fails because
.
There is a formula about the distance between two points in the plane.
M(a,b) and Т(с,d)
The distance between M and N is L=sqrt[(a-c)^2+(b-d)^2)]
So the <span>magnitude of this vector is sqrt[(-6+10)^2+(-4+4)^2]=sqrt(16+0)=4
b=d This means that vector JK is</span> <span>parallel to the OX axis(there is a picture)</span>
Y=-5x-7. I'm almost certain but you never know
