Answer:
y = -1x + 1
Step-by-step explanation:
-3/8x - 11 = 4
-3/8x = 15 Add 11 to both sides
x = -40 Divide both sides by -3/8
We have been that frequency (y) varies inversely with wavelength (x).
We know that two inversely proportional quantities are in form 
, where a is inversely proportional to b and k is constant of variation.
Our required equation would be 
.
To find frequency of blue light, we will substitute 
and 
in our equation as:
Therefore, the frequency of blue light is 764.
Answer:
Money invested in CD account: $2000
Money Invested in Savings Bond: $4000
Step-by-step explanation:
Given
Total amount=$6000
Let
x be the amount invested in CD at 4%
And
6000-x be the remaining amount invested in savings bond at 7%
So mathematically writing
0.04x+0.07(6000-x)=360
0.04x+420-0.07x=360
-0.03x+420=360
-0.03x=360-420
-0.03x= -60
x= -60/(-0.03)
x=$2000
So the amount invested in CD is $2000.
And the amount invested in savings bond is:
=6000-x
=6000-2000
=$4000 ..
