Answer:
4(x-6)(x-1) = 0
Standard form: 4x^2-28x+24=0
Step-by-step explanation:
First, let's write an equation where the roots are 6 and 1.
To do that, we can use the intercept form <em>a(x-p)(x-q) = 0</em>, where <em>a</em> is the leading coefficient, and <em>p </em>and <em>q</em> are the roots.
We can therefore plug what we know into this equation:
4(x-6)(x-1) = 0
3/10 *1 = 3/10 so 3/10 * (100/100) = 300/1000 = 3/10
Answer:
15 days.
Step-by-step explanation:
46 - 16 = 30.
It falls 2 seconds behind each day so the number of required days
= 30 / 2 = 15.
Substitute 2x+1 where y is in the equation:
9x-2(2x+1)=8
Then distribute the -2(2x+1)
9x-4x+2=8
Then combine like terms (the x)
5x+2=8
Then do -2 on both side of the equation sign
5x+2=8
- 2 -2
Then you'd get
5x=6
Then divide 5 on both sides
X= 1.2
Answer:
41.667 to the nearest thousandth.
Step-by-step explanation:
z = kx/y where k is the constant of proportionality.
Inserting the given values:
66.666666666667 = k*20/6
20k = 6*66.666666666667
k = 6*66.666666666667 / 20
= 20
So the equation of variation is z = 20x /y
When x = 25 and y = 12:
z = 20*25/12
= 41.666666666667.
