Answer:
d = 10/72
Step-by-step explanation:
c and d vary inversely
c = k/d
Where,
k = constant of proportionality
d = 2/9 when c = 5
c = k/d
5 = k ÷ 2/9
5 = k × 9/2
5 = 9k/2
Cross product
5*2 = 9k
10 = 9k
k = 10/9
c = k/d
c = 10/9 ÷ d
c = 10/9 × 1/d
c = 10/9d
find d when c = 8
c = 10/9d
8 = 10/9d
Cross product
8*9d = 10
72d = 10
d = 10/72
Its the last one
Y= rad x-5
w(x) = 35x + 2
It's a linear function. The graph is a straight line. Therefore we need only two points to plotting the graph. Choose two values of x and calculate the values of y:
for x = 0 → y= 35(0) + 2 = 0 + 2 = 2 → (0, 2)
for x = -1 → y= 35(-1) + 2 = -35 + 2 = -33 → (-1, -33)
The graph is in attachment.
Answer:
7 units
Step-by-step explanation:
If we want the profit to break even with the cost, then we must make the equations for cost and profit equal to each other.
3n-2=5+2n
First, we can subtract 2n from both sides and we get :
n-2=5
Next, we add 2 to both sides, and we get :
n=7
Therefore, we will need 7 units to break even with the cost and profit.
Ok so first u would add 3+1 which gives u 4 and then add 1/4 which should give u 4 1/4
