Answer:
<em>y = 150</em>
Step-by-step explanation:
<u>Proportions</u>
It's given y is directly proportional to the square of x-1. It can be expressed as:
Where k is the constant of proportionality. We know y=24 when x=3. Substituting:
Solving for k:
k = 24/4 = 6
Thus, the equation is:
When x=6:
y = 150
To get the answer you pretty much take 24.95x.395/ Then add that answer to 24.95.
Perpendicular lines have slopes that multiply to -1
y=mx+b
slope=m
y=5x+3
5=slope
5 times what=-1
divide both sides by 5
what=-1/5
the equation of a line that passes through the point (x1,y1) and has a slope of m is
y-y1=m(x-x1)
given
m=-1/5
point=(-1,-1)
y-(-1)=-1/5(x-(-1))
y+1=-1/5(x+1)
y+1=-1/5x-1/5
y=-1/5x-6/5
1/5x+y=-6/5
x+5y=-6
the euation is
y+1=-1/5(x+1) or
y=-1/5x-6/5 or
x+5y=-6 (all same equation but different forms)
Answer:
1/12
Step-by-step explanation:
The probability of first choosing a green marble is 1/4, because there is one green and 4 total.
<u>When you don't replace the green marble,</u> the total number of marbles is now 3, and there is one red marble in the bag. So the second probability is 1/3.
These are independent events, so we multiply them together to get
1/4 * 1/3 = 1/12
It’s actually 25 not 50 so don’t scam bye
