Answer:
the first : all real numbers
Step-by-step explanation:
the domain is the interval or set of all valid values for x.
reflecting the graph over the x-axis simply means to multiply the original function by -1.
that does not change the domain in any case. it only changes the range (the interval or set of possible y values).
so, the domain is the same as for the original function : all real numbers.

Sam is making a metal box as part of a sculpture. She wants to know how much metal is needed to make a box with the dimensions shown. What is the surface area of the box?
A. 18 square meters
B. 6 square meters
C. 22 square meters
D. 11 square meters
Answer:
C. 22 square meters
Step-by-step explanation:
The surface area of a rectangular prism can be found from the formula ...
A = 2(LW +H(L +W))
Filling in the given values, we have ...
A = 2(2×3 +1×(2+3)) = 2(6 +5) = 22
The surface area of the box is 22 square meters.
Triangle ABC is isosceles, with AB = AC.
r\1180
Work out the size of angle x.
Help!!!
x = 180 - 118 ( linear angles)
x = 62
62+62+y = 180
y = 56
Answer:
Step-by-step explanation:
Angle of a straight line = 180 degrees :)
So to find x you would do:
x = 180 - 118 = 62
Also the angle sum of a triangle = 180 degrees.
Since it is an isosceles triangle, the bottom two angles would be equal:
Angle sum of triangle = 180
x + x + y = 180
Since we know x = 62, substitute it into the above equation:
62 + 62 + y = 180
124 + y = 180
Subtract 124 from both sides to solve for y.
y = 180 - 124
y = 56

Answer:
The original price is $7926.83
Step-by-step explanation:
Step 1: Subtract the percent of the discount from the percent of the original cost:
100% - 18% = 82%
Step 2: Convert the percent to a decimal.
82% = 0.82
Step 3: Solve for the original price.
[tex]\frac{0.82x}{0.82} = \frac{6500}{0.82}[/tex]
= 7926.829268 (Round to the nearest tenths)
$7926.83

Answer:
x = 8.4
Step-by-step explanation:
For the 51° angle, 5.3 is the adjacent leg.
x is the hypotenuse.
cos 51° = adj/hyp
cos 51° = 5.3/x
x = 5.3/cos 51°
x = 8.4
Which of the following is parallel to the line y= 2/3x +5
Answer: y= 2/3x + 8
Two lines are parallel if they have the same slope.
2/3x is the slope so the only thing needed to change to make it parallel is the y-intercept.

After watching baking shows on T. V. , Sanjay signs up for a cake-decorating class. To practice his new skills, he decorates a batch of cupcakes with sugar flowers. Sanjay puts 4 sugar flowers on each cupcake. In all, Sanjay puts 32 sugar flowers on the cupcakes. Which equation can you use to find the number of cupcakes c Sanjay decorates?
Answer:
4 sugar flowers for each cup
Total number of cups = 32
Generating The Equation
number of cupcakes (n) = (total cupcakes decorated)/( number of sugar flowers for each cup)n = 32/4n = 8The equation that can be use to determine the number of cupcakes c Tucker decorates will be 4n = 32.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Given that 4 sugar flowers for each cup
Total number of cups = 32
Generating The Equation;
The number of cupcakes (n) = (total cupcakes decorated)/( number of sugar flowers for each cup)
n = 32/4
n = 8
The equation that can be use to determine the number of cupcakes c Tucker decorates will be 4n = 32.

Step-by-step explanation:
f(1) .here x = 1 and this is less than 4. so, we have to choose
f(x) = -(x - 2)² - 3
f(1) = -(1-2)² - 3
= - (-1)² - 3
= - (1) - 3
= -1 - 3

Jim is going to plant grass in a rectangular area that is 15 feet long and 10 feet wide.At the store, there are bags of grass and seed that will cover 200 square feet. Willone bag be enough
The area of the plant grass is the amount of plant grass on the field
It is true that one bag of grass and seed will be enough
How to determine if the bag will be enough?
The dimension of the rectangular area is:
15 feet by 10 feet
So, the area of the rectangular garden is:
Area = 15 feet * 10 feet
Evaluate the product
Area = 150 square feet
There are bags of grass and seed that will cover 200 square feet.
200 square feet is greater than 150 square feet
Hence, one bag of grass and seed will be enough

Melvin mows a lawn. The fraction of the lawn that Melvin has mowed so
"far is represented by the shaded model shown.
3
Melvin will mow more of the lawn before he takes his first break.
10
What fraction of the lawn will Melvin have mowed when he takes his
first break?
Melvin would have mowed 12/25 of the lawn of the when he takes his first break.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
The total number of squares in the lawn = 100, 3/10 of the lawn = (3/10) * 100 = 30 squares
The number of squares already mowed = 18
Hence:
Fraction of the lawn Melvin have mowed when he takes his first break = (18 + 30) / 100 = 48/100 = 12/25
Melvin would have mowed 12/25 of the lawn of the when he takes his first break.

Which of the following expressions are equivalent to (x+4y)^2 check all that apply: A. x^2+8xy+16y^2 B. x^2+2xy+2y(x+2y) C. x^2+16y^2 D. x^2+4xy+4y(x+4y) Question 2. If the expression ax(2x+y-5) simplifies to 6x^2+3xy-15x, what is the value of a? Type only the numeric value into the box.
Given:
The expression is [tex](x+4y)^2[/tex].
The expression [tex]ax(2x+y-5)[/tex] simplifies to [tex]6x^2+3xy-15x[/tex].
To find:
The equivalent expression.
The value of a.
Solution:
The expression is
[tex](x+4y)^2[/tex]
Using [tex](a+b)^2=a^2+2ab+b^2[/tex], we get
[tex](x+4y)^2=x^2+2(x)(4y)+(4y)^2[/tex]
[tex](x+4y)^2=x^2+8xy+16y^2[/tex]
Therefore, the correct option is A.
The expression [tex]ax(2x+y-5)[/tex] simplifies to [tex]6x^2+3xy-15x[/tex]. So,
[tex]ax(2x+y-5)=6x^2+3xy-15x[/tex]
[tex]2ax^2+axy-5ax=6x^2+3xy-15x[/tex]
On comparing the coefficient of [tex]x^2[/tex],, we get
[tex]2a=6[/tex]
Divide both sides by 2.
[tex]a=3[/tex]
Therefore, the value of a is 3.
