A and C are equivalent.
6d+6=2(3d+3)
6d+6=3d+3+3d+3=(3d+3)+(3d+3)
Answer:
A and C
Step-by-step explanation:
Given
4d + 6 + 2d ← collect like terms
= 6d + 6
Comparing the following
A
2(3d + 3) ← distribute parenthesis by 2
= 6d + 6
B
6(d + 6) ← distribute parenthesis by 6
= 6d + 36 ≠ 6d + 6
C
(3d + 3) + (3d + 3) ← remove parenthesis
= 3d + 3 + 3d + 3 ← collect like terms
= 6d + 6
Thus A and C are equivalent to the original expression

What are the zeros of f(x) = x2 + x – 30?
A. x = –6 and x = 5
B. x = –5 and x = 6
C. x = –15 and x = 2
D. x = –2 and x = 15
Answers
Answer:
Answer A is correct. (x + 6)(x - 5) = x^2 + x - 30.
Step-by-step explanation:
Note that -30 = (-5)(6) and (5)(-6). This quadratic can be factored easily:
x^2 + x - 30 = (x + 6)(x - 5) is correct because 6x - 5x = x, the middle term of x^2 + x - 30.
Setting each factor equal to zero, one by one, we get:
x + 6 = 0 => x = -6, and x - 5 = 0 => x = 5
Answer A is correct.
Identify the points which of the following coordinate pairs make the equation x - 9y = 12 true?
Show your reasoning.
1. ( 12, 0 )
2. ( 0, 12 )
3. ( 3, -1 )
4. ( 0, - 4/3 )
Answers
Answer:
Step-by-step explanation:
Because in equation x-9y=12
If we put x=12 and y=0 then it satisfy equation. (12)-9(0)=12
So, (12,0) make equation
(3,-1) also make equation
(3)-9(-1)=12
(0,-4/3) also make equation
Because
0-9(-4/3)=12
Only (0,12) is not making
Beacuse
(0)-9(12) is not equal to 12

what is the mean, median, mode and range of 7, 2, 1, 4, 1
Answers
1 + 1 + 2 + 4 + 7 = 15
15 / 5 = 3.
The median is the middle number in a list of numbers ordered from smallest to largest, so the median is 2.
1, 1, (2), 4, 7
The mode is the value that appears most often in a set of data. In this case, the mode is 1.
1: 2
2: 1
4: 1
7: 1
The range is the difference between the highest value and the lowest value, so the range here is 6.
Highest value: 7
Lowest value: 1

. Larry solved this equation. 3(2-3)= x Which representation could Larry have used to solve this equation?
Answers
Answer:
x = -3
Step-by-step explanation:
Given the expression solved by Larry as;
3(2-3) = x
We are to find the equivalent expression x
Using the distributive law;
3(2) - 3(3) = x
6 - 9 = x
-3 = x
Swap
x = -3
Hence Larry could use the distributive law to solve the expression

A system has an infinite number of solutions. one equation is 3x-3y=8. Which could be the other equation in the system of equations?
Answers
Answer:
[tex]6x-6y-16=0[/tex]
Step-by-step explanation:
Consider the following system of equations:
[tex]a_1x+b_1y+c_1=0\\\\a_2x+b_2y+c_2=0[/tex]
The system of equations has infinite solutions if [tex]\frac{a_1}{a_2}=\frac{b_1}{b_2}=\frac{c_1}{c_2}[/tex]
One equation is [tex]3x-3y=8[/tex]
[tex]3x-3y-8=0[/tex]
Take another equation as [tex]6x-6y-16=0[/tex]
So, the two equations are [tex]3x-3y-8=0[/tex] and [tex]6x-6y-16=0[/tex]
[tex]a_1=3,b_1=-3,c_1=-8,a_2=6,b_2=-6,c_2=-16[/tex]
[tex]\frac{a_1}{a_2}=\frac{3}{6}=\frac{1}{2}\\ \frac{b_1}{b_2}=\frac{-3}{-6}=\frac{1}{2}\\ \frac{c_1}{c_2}=\frac{-8}{-16}=\frac{1}{2}[/tex]
So,
[tex]\frac{a_1}{a_2}=\frac{b_1}{b_2}=\frac{c_1}{c_2}[/tex]
Therefore, another equation can be [tex]6x-6y-16=0[/tex]

Answer:
Slope of the line 'm' = 5
Step-by-step explanation:
Step(i):-
Given that the straight line
5 x - y = 20
⇒ 5x - 20 = y
y = 5 x - 20
Step(ii):-
The equation of the straight line having to slope 'm'
y = m x + c
given that the straight line
y = 5x +20
comparing y = m x + c
Slope of the line 'm' = 5
Bus A travels according to the function y = 125 /2 x where y is distance traveled in miles and x is time in hours. Bus B travels according to the graph below, where the distance y is a function of time x . Which bus travels faster? Include all necessary calculations in your final answer.

Answer:
Bus B travels faster.
Step-by-step explanation:
The graph of the question in the attached figure
we know that
the linear equation in slope intercept form is equal to
where
m is the slope
b is the y-intercept
x ---> is the time in hours
y ---> is the distance in miles
In this problem we have
Bus A
The slope of the linear equation represent the speed of the bus
so
The speed of bus A is
Bus B
Find the slope
take two points from the graph
(0,0) and (3,200)
The formula to calculate the slope between two points is equal to

Compare the slope Bus A with the slope Bus B
therefore
Bus B travels faster.

A circle is shown. Secant X Z and tangent W Z intersect at point Z outside of the circle. Secant X Z goes through the center of the circle and intersects the circle at point Y. The length of W Z is k + 4, the length of Z Y is k, and the length of X Y is 12.
What is the length of line segment XZ?
Answers
Given:
Consider the below figure attached with this ques.
To find:
The length of the line segment XZ.
Solution:
According to the tangent-secant theorem, the square of tangent is equal to the product of secant and external segment of secant.
Using tangent-secant theorem, we get
[tex]WZ^2=ZX\times ZY[/tex]
[tex](k+4)^2=(k+12)k[/tex]
[tex]k^2+8k+16=k^2+12k[/tex]
[tex]8k+16=12k[/tex]
Subtract both sides by 8k.
[tex]16=12k-8k[/tex]
[tex]16=4k[/tex]
Divide both sides by 4.
[tex]4=k[/tex]
Now,
[tex]XZ=12+k[/tex]
[tex]XZ=12+4[/tex]
[tex]XZ=16[/tex]
Therefore, the measure of XZ is 16 units.

A 945 in
B. 1,287 in
C. 2,835 in
D. 3,780 in
Answers
Answer:
2835 inches cubed
Step-by-step explanation: Volume equals all three sides multiplied by each other so 30*12*10.5=3780 in. However because the tank is only 3/4 full you multiply 3780 by 3/4 to get 2835.
