Answer:
The value of y in the given equation is B. 30.
Step-by-step explanation:
y = 2x² - 4x x = 5
y = 2(5)² - 4(5) Plug 5 in for x
y = 2(25) - 20 Square 5 and multiply 4 by 5
y = 50 - 20 Multiply 2 by 25
y = 30

Answer:
$3
Step-by-step explanation:
Given data
Let the cost of drinks be x
and the cost of hotdogs be y
so
3x+4y=15-------1
also
3x+y= 10.5------2
solve 1 and 2
3x+4y=15
-3x+y= 10.5
3y= 4.5
divide both sides by 3
y= 4.5/3
y= $1.5
Put y= 1.5 in 1
3x+4(1.5)=15
3x+6= 15
3x=15-6
3x= 9
x= 9/3
x= $3
Hence the cost of a drink is $3
P = $2000, Rate, r = 6% = 0.06 per year, Time, t = 5 years.
For compound interest compounded annually:
A) Amount, A = P(1 + r)^t
A = 2000(1 + 0.06)⁵
A = 2000(1.06)⁵ ≈ 2676.45
Amount ≈ $2676.45
<span>B) Interest = Amount - Principal </span>
= 2676.45 - 2000 = 676.45
<span>Interest ≈ $676.45<span> </span></span>
