.All whole numbers that are multiples of 4
.All real numbers
Answers
The practical domain of function f(x) has all positive integers and all whole numbers that are multiples of 4 that is option A or D is correct
What is domain?The domain is "set of all possible inputs value for the function".
According to the question,
A package of buttery round crackers contains 4 sleeves of crackers each
package of crackers cost $2.49. A function f(x) written to represent the cost of purchasing x packages of crackers.
In order to find the practical domain for the function f(x) only if analysis the value of domain function 'x' must positive number so contain 'all positive integers' and since a package of buttery round crackers contains 4 sleeves then domain must contain 'all whole numbers that are multiples of 4'.
Hence, the practical domain of function f(x) has all positive integers and all whole numbers that are multiples of 4.

what percent of 7 is 3.5
Answers
Answer:
50%Step-by-step explanation:
what percent of 7 is 3.5
3.5 is half of 7, so 100%: 2 = 50%
Answer: 50%
I have shown two methods, both work well and can be used to solve other scenarios as well.
[Method One]
We will set up a proportion and solve.
-> A percent divided by 100 is a decimal. This means 100% = 1 in our proportion
[tex]\frac{1}{7} =\frac{x}{3.5}[/tex]
7x = 3.5
x = 0.5
0.5 * 100 = 50%
[Method Two]
We will put the whole value in the denominator, and the "what percent of" value is the numerator.
[tex]\displaystyle \frac{3.5}{7}[/tex]
0.5
0.5 * 100 = 50%

Oy + 5x = x² + 10 + 4x - 10
00=x²-9x
00=x²-9x + 20
One x-value of a solution to the system is 4.
Answers
Answer:
0 = x² - 9x + 20
4 is a solution for the system.
Step-by-step explanation:
y + 5x = x² + 10
y = 4x -10
Replacing the value of y in the first equation. This method is called sustitution.
(4x -10) + 5x = x² + 10
4x - 10 + 5x = x² + 10
4x + 5x - 10 = x² + 10 organizing.
9x - 10 = x² + 10 sum of similar terms.
0 = x² + 10 -9x + 10 organizing.
0 = x² - 9x + 10 + 10 organizing.
0 = x² - 9x + 20 sum of similar terms.
What happens if replace 4 in the equation.
0 = 4² - 9(4) + 20
0 = 16 - 36 + 20
0 = -20 + 20
0 = 0 I find that 4 is a solution for the system.
Find the distance between the pair of points.
(2, 0) and (-1, 1)
Answers
Step-by-step explanation:
given points (2,0) and (-1,1)
let A(2,0) and B(-1,1)
A(2,0) B( -1,1 )
(x1 , y1) (x2 , y2)
AB = √(x2 - x1)² + (y2 - y1)²
= √(-1 - 2)² + ( 1 - 0 )²
= √(-3)²+ 1²
= √9 + 1
= √10
Therefore,distance between given points is √10
If A'B' is 8 find the length of AB.
If angle B is 40 degrees what is the measurement of B'?
If angle A is 80 degrees what is the measurement of A'?
Using AA what is the measurement of angle C?
Answers
The length of AB when A'B' is 8 is 12
The measurement of B' when angle B is 40° is also 40°
The measurement of A' when A is 80° is also 80°
The measurement of C using AB is 60°
What are similar triangles?Similar triangles are triangles that have the same angles and the ratio of their corresponding sides are equal.
Analysis:
ΔCA'B' is similar to ΔCAB.
Which means [tex]\frac{A'B'}{AB}[/tex] = [tex]\frac{CB'}{CB}[/tex] = [tex]\frac{CA'}{CA}[/tex]
A'B' = 8, CA' = 4, CA = 6
[tex]\frac{8}{AB}[/tex] = [tex]\frac{4}{6}[/tex]
4AB = 8 X 6
AB = 48/4 = 12
Line BA nd B'A' are parallel lines joined by two transversals BC and CA.
So, ∠B = ∠B' = 40°( corresponding angles are equal)
Also, ∠A = ∠A' = 80° ( corresponding angles are equal)
∠A + ∠B +∠C = 180( sum of angles in a triangle)
80 + 40 + ∠C = 180
120 + ∠C = 180
∠C = 180 - 120 = 60°
In conclusion,
The length of AB when A'B' is 8 is 12
The measurement of B' when angle B is 40° is also 40°
The measurement of A' when A is 80° is also 80°
The measurement of C using AB is 60°.
