For us to get the solutions of the given function, we let f(x) be equal to zero and solve for the values of x.
f(x) = 12x² - 13x + 3 = 0
To get the two values of roots, a and b, we use the concepts presented below.
a + b = -B/A
ab = C/A
Substituting the known values,
a + b = -(-13/12) = 13/12
ab = 3/12
The values of a and b from the equation are 3/4 and 1/3, respectively.
The solution set then becomes {3/4, 1/3}.
Answer:
the unit cost per item
Step-by-step explanation:
The description of the graph tells you what the slope means. The slope is the (change in) y-value (cost) per (change in) x-value (item), thus is cost per item.
The slope of the line from the origin to a point is the average cost for that number of items. The slope of a tangent line at a point on the curve is the marginal cost for that number of items.
When the curve is linear and goes through the origin, the slope is the same everywhere and is the cost per item. (It is also the average cost and the marginal cost, where that is of interest.)
Answer:
91 campers can swim
Step-by-step explanation:
step 1
Find the number of campers
we know that
The ratio of counselors to campers at a camp is 1 : 9
so
by proportion
Find the number of campers if there are 13 counselors
Let
x-----> the number of campers
1/9=13/x
x=9*13=117 campers
step 2
How many campers can swim?
we know that
The ratio of campers who can swim to campers who cannot swim is 7 : 2
so
The ratio of total campers to campers who can swim is 9 : 7
by proportion
Find how many campers can swim for a total of 117 campers
Let
x----> the number of campers that can swim
9/7=117/x
x=117*7/9
x=91 campers can swim
Answer: they are divisible by 1,5,10,25,50
Step-by-step explanation:
Answer:
X=1, i'm not sure if it's correct i didn't check it, okay i just plugged it in, x is = to 1
Step-by-step explanation: First you have to get the variable to one side of the equation by using the inverse operation of subtraction which is addition and add -3x to 6x making it 9x, then from there continue to use inverse operations.
