Answer:
y < - 12
Step-by-step explanation:
y + 15 < 3 ( subtract 15 from both sides )
y < - 12
Answer:
y=-2x-13
Step-by-step explanation:
y-y1=m(x-x1)
y-(-13)=-2(x-0)
y+13=-2x
y=-2x-13
Answer:
y = 60
Step-by-step explanation:
<h3>Step 1: Make sense of the given</h3>
"The ratio of y to x is 3"
This means that, 
"The sum of y and x is 80"
This means, 
<h3>Step 2: Make use of the facts</h3>
If
, then
.
We can plug this into the other equation by substitution:

This simplifies to:

Which we can solve out and get:
.
<h3>Step 3: Plug and Chug</h3>
We solved for x, but we need the value of y.
So, we go back to the equation we first derived: "
".
And now we substitute the value of x, into this.

By solving this out, we get:

So, the value of y is 60.
For the answer to the question above, I'll provide a computation on my answer to give clarity and understanding to my answer.
<span>P(z> 0.64) = 1- P(z<0.64) </span>
<span>P(z<0.64) = .73891 </span>
<span>P(z> 0.64) = 1- 0.73891 =
So the answer to your question is
0.26109
I hope my answer helped you. Have a nice day!</span>
(x+4) and (y+4) both have two terms..terms are separated by addition/subtraction operators
