Answer:
x = - 5
Step-by-step explanation:
Given
f(x) = 
The denominator of f(x) cannot be zero as this would make f(x) undefined. Equating the denominator to zero and solving gives the value that x cannot be.
solve : 3x + 15 = 0 ⇒ 3x = - 15 ⇒ x = - 5 ← excluded value
Domain x ∈ R , x ≠ - 5
Answer:
The amount of interest earned for the year is $37.7
Step-by-step explanation:
The formula for simple interest is expressed as
I = PRT/100
Where
P represents principal or amount invested.
T represents the time
R represents the interest rate
I represents the interest
From the information given,
You want to put $580 into a saving account for 1 year. This means that
P = $580 and
T = 1 year
R = 6 1/2 = 6.5%
I = (580× 6.5×1)/100 = $37.7
I think
(Total)
3 : 6 : 8 = 17
(Times by 30 to get total then you times by each ratio/side)
90 : 180 : 240= 510cm
Answer:
4,301,970
5,149,815
Step-by-step explanation:
The cost of a bicycle is 2895
Therefore the cost of 1486 bicycles is
= 2895×1486
= 4,301,970
A truck can carry 6785 kg of food
Therefore the amount in which 759 truckj can carry can be calculated as follows
= 6785×759
= 5,149,815
From second equation y = 8 - x so
7x + 2(8 - x) = -14
5x = -14 - 16 = -30
x = -6
and y = 8 - -6 = 14
Answer x=-6,y=14
