Find the zero of the function below:
f(x) = 4x + 12

Answers

Answer 1

Answer:

x = - 3

Step-by-step explanation:

To find the zero, let f(x) = 0, that is

4x + 12 = 0 ( subtract 12 from both sides )

4x = - 12 ( divide both sides by 4 )

x = - 3 ← is the zero

Answer 2
Solve the equation for
x
, when
f
(
x
)
=
0

Then,
x
=
3
.
Explanation:
I assume you mean to find the solution/root (radical)
x
, when
f
(
x
)
=
0
.
Then, this is simple.
Just set
f
(
x
)
to 0 and solve the equation for
x
:
f
(
x
)
=
4
x
−
12
=
0
First we can add 12 on both sides of the equality:
4
x
−
12
+
12
=
0
+
12

which becomes
4
x
=
12
We can now divide both sides of the equality by 4:
4
x
4
=
12
4

and we have
x
=
3
The "zero", or the solution for
f
(
x
)
=
0
is
x
=
3
.

in a country , 17 out of every 20 people are literate. how many people out of 100 people in the country are literate​

Answers

Answer:

85 people

Step-by-step explanation:

in a country , if 17 out of every 20 people are literate, then;

17 literate = 20 people

To get the number of literate people in 100

x literate = 100 people

Divide both expressions

17/x = 20/100

Cross multiply

20x = 17 * 100

x = 1700/20

x = 85

Hence 85 people are literate out of 100 people

What is a unitary method ?

In simple terms, the unitary method is used to find the price of a single unit from a given multiple.

Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.

We are given that Vickie earned $6 an hour while working 11 hours over the weekend she put one third of what she and in a savings account

Therefore,

$6 x 11 hours = $66

Now we know that 1/3 of $66 = $22

Hence, She put $22 into the account.

Answers

Answer:

Hello your question is not well written hence I will given a general answer with some assumptions

lets assume ; Triangle A : height = 4 , base = 2

                      Triangle B : height = 6 , base = 4

Step-by-step explanation:

Given data :

Triangle A : height = 4 , base = 2

Triangle B : height = 6 , base = 4

Area of triangle = 1/2 bh

Area of triangle of A = 1/2 * 2 * 4 = 8/2 = 4 cm^2

Area of triangle of B = 1/2 * 6 * 4 = 24/2 = 12 cm^2

Hence the area of triangle B is greater than triangle A by

= 12 - 4 = 8cm^2 ( apply the same principle to the complete question and you will get your answer )

If s = 6 and t = 4 , find the value of x which makes the following equation true.

Answers

Answer:

6

Step-by-step explanation:

replace the variable with the information provided which will give you

x=4+6-4

solve

answer:6

The value of x is 6 which makes the equation x = 4 + s - t true.

What is the equation?

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that is equal.

Given equation as :

x = 4 + s - t

And s = 6 and t = 4

To determine the value of x

Substitute the values of s = 6 and t = 4 in the equation,

⇒ x = 4 + 6 - 4

⇒ x = 10 - 4

⇒ x = 6

Hence, the value of x is 6 which makes the equation x = 4 + s - t true.

Kate purchased a car for $23,000. It will depreciate by a rate of 12% a year. What is the value of the car in 4 years. *

The formula for Depreciation rate =

y = a(1 - r) ^t

Where

y = Value of the car after t years

a = Initial value of the car = $23,000

t= time in years = 4 years

r = Depreciation rate = 12% = 0.12)

y = $23000 (1 - 0.12)⁴
