Y=mx+b
m=slope
b=yintercept
input points
when x=1
y=1
1=1m+b
and
x=2
y=-2
-2=2m+b
multilpy first equaiton by -1 and add to othe requation
-1=-m-b
<u>-2=2m+b +</u>
-3=m+0b
-3=m
y=-3x+b
1=-3(1)+b
1=-3+b
add 3
4=b
y=-3x+4
first blank is -3
second is 4
Answer:
ST = 5
Step-by-step explanation:
3/12 = ST/(ST+15)
12ST = 3ST+45
9ST = 45
ST = 5
Take half of the coefficient of x: It is 3, and half that is 3/2.
Then <span>x^2+3x=6 becomes:
</span><span> x^2+3x + (3/2)^2 =6 + (3/2)^2, and
(x+3/2)^2 = 6 + 9/4
You were not asked to solve the equation, but why not do it for the practice?
</span>Solve (x+3/2)^2 = 6 + 9/4 for x. There will be 2 values.
12
-4
-8
Those should be the answers
