Step-by-step explanation:
=4x+5
=4*4+5
=16+5
=21
The value of function f(x) = 4x + 5 when x = 4 is 21 the answer is 21.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
f(x) = 4x + 5
Plug x = 4
f(4) = 4(4) + 5
f(4) = 16 + 5
f(4) = 21
Thus, the value of function f(x) = 4x + 5 when x = 4 is 21 the answer is 21.

-2w - 5w simplify the expression and combine like terms
Answer:
-7w
Step-by-step explanation:
-2w-5w
so you have to subtract -2 times 5 for now you can ignore the variable and just subtract them. But when you get your answer you have to place w next to it. YOu can ignore the variable because they have the same variable. But with -2w-5x you can't and also it is not possible two subtract -2w from 5x

Is x=3 a zero of f(x)=4x^4-x^3-52x^2-35x+12
Answer:
no
Step-by-step explanation:
If x = 3 is a zero, then f(3) = 0
f(3)
= 4[tex](3)^{4}[/tex] - 3³ - 52(3)² - 35(3) + 12
= 324 - 27 - 468 - 105 + 12
= - 264
Since f(3) ≠ 0 then x = 3 is not a zero of f(x)

Jolie purchased a concert ticket on a web site. The original price of the ticket was $110. She used a coupon
code to receive a 15% discount. The web site applied a 10% service fee to the discounted price. Jolie's ticket
was less than the original price by what percent?
Answer:
I got 7%
Step-by-step explanation:
110 x .15 = 16.5
110-16.5=93.5
93.5 x .10 = 9.35
93.5 + 9.35= $102.82
Thats the discount price
110 - 102.82 + 7.18
7.18/102 = .0698
.0698 x 100 = 6.98
7%

If the cost of an item with VAT is Rs 1,356 and without VAT is Rs 1,200, find the VAT?
Given:
Cost of an item with VAT = Rs 1,356
Cost of that item without VAT = Rs 1,200.
To find:
The VAT.
Solution:
We have,
Cost of an item with VAT = Rs 1,356
Cost of that item without VAT = Rs 1,200.
We know that,
VAT = Cost of an item with VAT - Cost of that item without VAT
= 1356 - 1200
= 156
Therefore, the value of VAT is $156.

What is Translation?Each point in a figure is moved the same distance in the same direction using a type of transformation known as translation.
A transformation known as a translation involves moving each point in a figure uniformly and in the same direction.
Given:
Triangle DEF is reflected over the y-axis to form triangle D'E'F'.
now, we have the rule for reflection over y axis
P( x, y)-----> P' (-x, y)
Then the coordinates of D'E'F are
D(4, 1)---------> D'(-4, 1)
E(8, -3)---------> E'(-8, -3)

work out an estimate for sqrt 63.6 x 102.3
Answer:
81
Step-by-step explanation:
Round 63.6 to 64
Round 102.3 to 102
Multiply 64 × 102=6528
Square root 6528 to get 80.796
Round 80.796 to 81
The estimate square root value of 63.6 x 102.3 is 81
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be A
The value of A is
A = square root of 63.6 x 102.3
A = √63.6 x 102.3
Now , the value 63.6 can be approximated as 64
And the value 102.3 can be approximated as 102
So , the equation becomes
A = √ ( 64 x 102 )
A = 8 x √102
A = 8 x 10.099
A = 80.79
The value of A can be approximated as
A ≈ 81
Therefore , the value of A is 81
Hence , The estimate square root value of 63.6 x 102.3 is 81
