a is the leading coefficient
x_1 and x_2 are the zeroes of the function
substitute the given values

Find the value of a
Remember that
For x=0 ----> f(0)=4
substitute


so




Answer:
Step-by-step explanation:
I= PRT ÷ 100
P is principal
R is rate (%)
T is time (years)
I = (25000 × 12 × 5) ÷ 100
= 15000
Answer:
The answer is B
Step-by-step explanation:
As the picture has already given you the answer, ∠BPD = 146°.
Answer:
Step-by-step explanation:
Jill makes purses and backpacks.
Let x represent the number of foot of fabric required to make a purse.
Let y represent the number of foot of fabric required to make a backpack.
To make each purse,she uses 1 foot less than half the amount of fabric she uses to make a backpack. This means that
x = (y/2) - 1
Therefore, the amount of fabric that Jill needs to make backpack will be
y/2 = x-1
y = 2(x-1) = 2x - 2
The number of feet of fabric that she will use to make a purse is
x = (y/2) - 1
Answer:
well... x is 35 if that's what your'e asking :)
