So first you would do y-y over x-x so it would be 3-12 over 4-7 which equals -9/3 so which is -3
You now plug it into y-3= -3(x-4) which equals y=-3x+15 so your b=15
D) these two figures are similar they don't look similar at first because the X'Z'Y' is more upwards. But they are congruent meaning they are similar or exactly the same almost. This basically tells me that I need to use translation.
E) I can use reflection to get XYZ into X'Y'Z' by reflecting it across the x-axis. I could also use translation and move it up 6 and then move it to the right.
C) The last one I could use is rotation and move it around around 45* or something close to the the other one.
Answer:
Step-by-step explanation:
Given:
Let's distribute the parenthesis
Let's subtract from both sides
Let's add to both sides
Now, let's divide both sides by to get alone
Hope this is helpful

Answer:
Step-by-step explanation:
Let X be length of life of the participants in the plan.
Given that X is N(68,3.5)
We convert this to standard normal score z using
a) proportion of the plan recipients that would receive payments beyond age 75=
b) proportion of the plan recipients die before they reach the standard retirement age of 65=
c) x for 86% ceased
