Answer:
B. )The graph of g(x) is a translation of the graph of f(x) right 6 units.
Step-by-step explanation:
When a positive number is directly added to an "x" variable (usually inside of parentheses), the graph is shifted to the left that many units.
When a negative number is directly added to an "x" variable, the graph is shifted to the right that many units.
A graph shifts up or down when a positive or negative number is added to the overall function. For example, if the -6 were outside of the parentheses, the graph would be translated 6 units downwards.
16 / 4 * (3 - 1)
a) 2
b) 4
c) 8
Hello,
if :
[tex] \frac{16}{4(3 - 1)} = \frac{16}{4 \times 2} = \frac{16}{8} = 2[/tex]
if :
[tex] \frac{16}{4} \times (3 - 1) = 4(3 - 1) = 4 \times 2 = 8[/tex]
Answer:
Hello! The answer is c) 8.
Step-by-step explanation:
To solve this question, we need to follow the order of operations. This can be done through PEMDAS - parentheses, exponents, multiplication, division, addition, and subtraction.
First, we need to solve what's in the parentheses:
[tex]\frac{16}{4} * 2[/tex]
Now we can multiply and we get:
[tex]\frac{32}{4}[/tex]
This can be further simplified by doing 32 ÷ 4 to get 8.
Therefore, the answer is c) 8
6. If x and y are positive integers, and
3x + 2y = 21, what is the sum of all
possible values of x?
An equation is formed of two equal expressions. The sum of all possible values of x is 16.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
3x + 2y = 21
3x = 21 - 2y
x = (21-2y)/3
Since the value of x is needed to be positive, the value of 2y must not exceed 21. Also, the value of (21-2y) must be a multiple of two.
Now, the values of y that will satisfy the given condition in the equation are 0, 3, 6, and 9.
Further, the sum of the possible values of x are,
Sum = 7 + 5 + 3 + 1 = 16
Hence, the sum of all possible values of x is 16.

A rectangular piece of paper is 44 cm long and 20 cm wide. A cylinder is forms by rolling the paper along its length. Find its volume
ASAP ⠀⠀⠀⠀⠀⠀⠀
Answer:
3081.24 cm³ (nearest hundredth)
Step-by-step explanation:
Formulas
[tex]\textsf{Circumference of a circle}=\sf 2 \pi r\quad\textsf{(where r is the radius)}[/tex]
[tex]\textsf{Volume of a cylinder}=\sf \pi r^2 h \quad\textsf{(where r is the radius and h is the height)}[/tex]
If a rectangular piece of paper is rolled along its length to form a cylinder:
circumference = 44 cmheight = 20 cmTo calculate the volume of the formed cylinder, determine the radius by using the circumference formula:
[tex]\implies \sf 2 \pi r = 44[/tex]
[tex]\implies \sf r = \dfrac{44}{2 \pi}[/tex]
[tex]\implies \sf r =\dfrac{22}{\pi}[/tex]
Substitute the round radius into the formula for Volume and solve for V:
[tex]\implies \sf V=\pi \left(\dfrac{22}{\pi}\right)^2(20)[/tex]
[tex]\implies \sf V=\pi \left(\dfrac{484}{\pi^2}\right)(20)[/tex]
[tex]\implies \sf V=\left(\dfrac{484}{\pi}\right)(20)[/tex]
[tex]\implies \sf V=\dfrac{9680}{\pi}[/tex]
[tex]\implies \sf V=3081.239698...cm^3[/tex]
Therefore, the volume of the cylinder is 3081.24 cm³ (nearest hundredth).

Answer:

Step-by-step explanation:
The "substitution method" for solving a system of equations requires that you write an expression that can be substituted for a variable in one or more of the other equations in the system.
Expression to substituteThe given equations are ...
y = x -82x +3y = 1We notice the first equation gives an expression for y. This is exactly what we want to substitute for y in the second equation.
SubstitutionWhen the expression (x-8) is substituted for y in the second equation, you get ...
2x +3(x -8) = 1
This simplifies to ...
5x -24 = 1
SolutionThis 2-step equation can now be solved in the usual way:
5x = 25 . . . . . . add 24 to isolate the variable term
x = 25/5 = 5 . . . . . divide by the coefficient of x
Note that we now know what the correct answer choice is.
Using the expression for y, we find ...
y = x -8 = 5 -8 = -3
The solution is (x, y) = (5, -3).

F. x - 4
G. 3x 9
445
H. 3x - 9
What is the answer
All the options are incorrect. the required average is (3x-9)/2.
Thermometer A reads xº.
Thermometer B reads 2° below the reading on thermometer A = x-2
Thermometers C and D each read 4° less than twice the reading on thermometer = 2(x-2)-4
Average of the values is the ratio of total sum of values to the number of values.
As per question,
A=x
B = x-2
C.D = 2(x-2)-4= 2x-8
Average = A + B + C + D /4
= x+x-2+2x-8+2x-8/4
= 6x-18/4
= 3x-9/2
Thus, the required average of temperature = 3x-9/2.
