Answer:
The answer to your question is The point (-3, 2) is not a solution
Step-by-step explanation:
Inequality
- 4x - 10y < - 9
-point (-3, 2)
Process
1.- To solve this problem, just substitute the point in the inequality and simplify
a) Substitution
-4(-3) - 10(2) < - 9
b) Simplification
12 - 20 < - 9
c) Result
- 8 < - 9
This is false, -8 > -9
Let x = length and y = width
You would have 2 lengths, so 2x and 3 widths, so 3y
Those need to equal total length of fence:
2x + 3y = 1200
The 3 widths would equal total fence minus the 2 lengths:
3Y = 1200-2x
Solve for y: y = 400 -2/3x
Area = length x width = xy. Replace y :
Area = x(400-2/3x) = 400x-2/3x^2
Differentiate:
400-4x/3 =0
4x/3 = 400
4x = 1200
X = 300
Y = 400-2/3(300) = 200
The dimension would be 300 ft x 200 ft
Answer: x=14
Step-by-step explanation:
Subtract 2
from both sides of the equation.
X=16−2
Subtract 2
from 16
.
X=14
Answer:
$250,000
Step-by-step explanation:
This is the correct question below;
Fran naders insurance coverage bodily Injury 25/100 and $100,000 property damage. It has a $50-deductible comprehensive and a $50-deductible collision. Her car is in age group C and Insurance-rating group 10(or C,10) and her driver-rating Factor is 1.50.
Find her annual premium.
To calculate this, we proceed as follows;
Mathematically,
Annual premium = Face amount * $1000
25/100 * 100,000 * 100
This is 25,000 * 100 = $250,000
