Answer:
a = 6
Step-by-step explanation:
use distribution method:
-3(4-a) = 6
-12+3a = 6
3a = 6+12
3a = 18
a = 18/3 = 6
_____________________________
Hey!!
Solution,
-3(4-a)=6
or, -12+3a=6
or, 3a=6+12
or, 3a=18
or,a=18/3
a=6
So the value of X is 6.hope it helps..
Good luck on your assignment

Which graph represents an odd function? There are 6 points ona coordinate plane. The points ]are (negative 5, 3), (negative 3, 1), (negative 1, 1), (1, 3), (3, negative 5), (5, negative 1). There are 8 points on a coordinate plane. The points are (negative 4, 2), (negative 3, negative 1), (negative 1, negative 3), (0, 1), (1, 0), (2, negative 4), (4, 5), (5, 4). There are 8 points on a coordinate plane. The points are (negative 4, 0), (negative 3, 1), (negative 2, negative 3), (negative 1, negative 2), (1, 2), (2, 3), (3, negative 1), (4, 0) There are 11 points on a coordinate plane.

Answer:
Option C.
Step-by-step explanation:
Let as consider f(x) is a function.
If [tex]f(-x)=f(x)[/tex], then f(x) is even function.
If [tex]f(-x)=-f(x)[/tex], then f(x) is odd function.
It means, if (x,y) is a point of the function, then (-x,-y)is also a point of the function.
In option A, (-5,3) is a point of the function, but (5,-3) is not a point of the function.
So, function in option A is not an odd function.
In option B, (-4,2) is a point of the function, but (4,-2) is not a point of the function.
So, function in option B is not an odd function.
In option C,
If (-4,0) is a point of function, then (4,0) is also the point of the function.
Similarly, (-3,1) and (3,-1), (-2,-3) and (2,3), (-1,-2) and (1,2) are points of the function.
So, function in option C is an odd function.
In option D, (-4,3) is a point of the function, but (4,-3) is not a point of the function.
So, function in option D is not an odd function.

Calculate the probability of all three events occurring.
Answer:
even = 1/2
prime = 1/2
multiple of 5 = 1/6
Step-by-step explanation:
probability is the chances of obtaining a certain result out of many attempts.
when rolling a die, the maximum number of results you can get is 6
Then, calculate how many times each of the occurrences appear(even, prime or multiples of 5)
Even = There are only 3 even numbers from 1 to 6
Prime: There are only 3 primes from 1 to 6
Multiples of 5 = There is only one multiple of 5.
Now you present each of this out of 6:
Even: 3/6 = 1/2
Prime: 3/6 = 1/2
Multiple of 5 = 1/6
This can also be presented as a decimal or percentage:
Even: 50% = 0.5
Prime: 50% = 0.5
Multiple of 5 = 16.67% = 0.16
Hope this helps.

Wang Xiu Ying is gift wrapping boxes in the shape of a cube for her class fundraiser. She calculates that the surface area, S SS, in square feet, of a cube-shaped box with a side of m mm feet is given by the function S ( m ) = 6 m 2 S(m)=6m 2 S, left parenthesis, m, right parenthesis, equals, 6, m, squared. She also finds that the cost, C CC, in dollars, of wrapping a box with a surface area of x xx square feet is given by the function C ( x ) = 0.15 x + 0.25 C(x)=0.15x+0.25C, left parenthesis, x, right parenthesis, equals, 0, point, 15, x, plus, 0, point, 25. Find an explicit expression that models the costs of wrapping a cube shaped box with a side length of m mm feet.
Answer:
[tex]C(m)=0.9m^2+0.25[/tex]
Step-by-step explanation:
The surface area of a cube-shaped box with a side of m feet is given by the function:
[tex]S(m)=6m^2[/tex]
The cost, C, in dollars, of wrapping a box with a surface area of x square feet is given by the function:
[tex]C ( x ) = 0.15 x + 0.25[/tex]
We want to find an explicit expression that models the costs of wrapping a cube-shaped box with a side length of m feet.
In the cost function, C(x), x is the surface area, therefore:
[tex]S(m)=x;$ and$\\C ( S(m) ) = 0.15(6m^2) + 0.25\\C(m)=0.9m^2+0.25[/tex]
To find the cost of wrapping a cube of side length m feet, we use the explicit function:
[tex]C(m)=0.9m^2+0.25[/tex]
Here is a list of numbers 17 21 14 17 12 15 16 A) work out the range of the numbers B) work out the mean of the numbers in the list
Answer:
Given below
Range: 9
Mean: 16
Hope it helps:)
Step-by-step explanation:
The data is given in the question
Range-
All we need to do is find the difference between the largest data value in our set and the smallest data value. Stated succinctly we have the following formula:
Range = Maximum Value–Minimum Value
= 21- 12
= 9
Mean-
The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. The formula is:
Sum of term/ number of terms = mean
= 17+21+14+17+12+15+16/7
= 112/7
= 16
The range and the mean of the given data are 9 and 16 respectively.
What is range?The range is the difference between the smallest and highest numbers in a list or set.
Given that, a data 17, 21, 14, 17, 12, 15, 16,
a) Range = The difference between the lowest and highest values
= 21-12
= 9
b) Mean = (sum of all data)/(number of data)
= (17+ 21+ 14+ 17+ 12+ 15+ 16)/7
= 112/7
= 16
Hence, The range and the mean of the given data are 9 and 16 respectively.

4. Two non-common sides of adjacent, complementary angles form
a) a straight angle
b) a reflex angle
c) a right angle
d) a linear pair
Answer:
c) a right angle
Step-by-step explanation:
A right angle can be defined as angles that are created or formed by two non-common sides of adjacent, complementary angles.
These angles have the following attributes:
a) They are angles that are complementary angles. This means that the sum of these angles is equal to 90°
b) The angles are adjacent complementary angles: These means that the angles are next to each other.
Two non-common sides of adjacent, complementary angles form a right angle because they have a common vertex and arm.
Answer:

Lester teaches a ceramics class on the weekends. In Sunday's class, the students created 19 clay objects, 12 of which were vases. After each class, Lester bakes the clay objects in a hot kiln to harden them. Students pick up their finished pieces later in the week.
If Lester randomly chose 16 clay objects to bake in the kiln Sunday night, what is the probability that exactly 11 of the chosen clay objects are vases?
Write your answer as a decimal rounded to four decimal places.
Step-by-step explanation:
Well they made 19 clay, where 12 were vases. That means 7 were not vases. She randomly chooses 16 clay objects, which then also means 3 were left behind. so if the vases are 12/19, which is approximately 63%, then 63% of the objects are vases. Makes sense, right? Well now we need to multiply that by the initial 11 in the question. After all of this work..

A new lawn has a perimeter of 278 ft. and a width of 64 ft. A bag of grass seed will cover 384 ft 2of ground. How many bags of grass seed are needed to seed the new lawn? A. 4.34 B. 6 C. 10.25 D. 12.5
Answer:
12.5 bagsStep-by-step explanation:
This problem is on the mensuration of flat shapes
Given
perimeter of lawn = 278 ft
width of lawn = 64 ft
1. we need to solve for the length of the lawn
2. we also we need to solve for the area of the lawn
perimeter of lawn= 2(width) + 2(length)
substituting our data we have
let the length be x
[tex]= 278= 2(64) + 2(x)\\\=278= 128+2x\\\=278-128= 2x\\\=150=2x\\\\\x=\frac{150}{2} \\\x= 75ft[/tex]
the length is 75 ft
the area of the lawn is [tex]75*64= 4800ft^2[/tex]
if a bag will cover[tex]384ft^2[/tex]
to cover the lawn we will need
[tex]\frac{4800}{384} \\=12.5 bags[/tex]

the length of two parallel sides of a trapezium are 91 cm and 51 cm and the length of two other side 37 CM and 13 cm respectively determine the area of trapezium
Answer:
903 sq. cm.
Step-by-step explanation:
It is given that the length of two parallel sides of a trapezium are 91 cm and 51 cm and the length of two other side 37 CM and 13 cm respectively.
Now draw a dotted line as shown in the below figure. So, we have a triangle with sides 13 cm, 37 cm, 40cm and a parallelogram with sides 51 cm, 13 cm.
Area of parallelogram is
[tex]A_1=base\times height[/tex]
[tex]A_1=51\times 13[/tex]
[tex]A_1=663[/tex]
Using heron's formula, area of triangle is
[tex]A=\sqrt{s(s-a)(s-b)(s-c)}[/tex]
where, [tex]s=\dfrac{a+b+c}{2}[/tex].
The sides of triangle are 13cm, 37 cm, and 40 cm.
[tex]s=\dfrac{13+37+40}{2}=45[/tex]
Area of triangle is
[tex]A=\sqrt{45(45-13)(45-37)(45-40)}=240[/tex]
The area of trapezium is
[tex]A=A_1+A_2=663+240=903[/tex]
Therefore, the area of trapezium is 903 sq. cm.
