Answers
Answer: [tex]y-1=\dfrac32(x+3)[/tex]
Step-by-step explanation:
Slope of a line passes through (a,b) and (c,d) = [tex]\dfrac{d-b}{c-a}[/tex]
In graph(below) given line is passing through (-2,-4) and (2,2) .
Slope of the given line passing through (-2,-4) and (2,2) =[tex]\dfrac{-4-2}{-2-2}=\dfrac{-6}{-4}=\dfrac{3}{2}[/tex]
Since parallel lines have equal slope . That means slope of the required line would be .
Equation of a line passing through (a,b) and has slope m is given by :_
(y-b)=m(x-a)
Then, Equation of a line passing through(-3, 1) and has slope = is given by
[tex](y-1)=\dfrac32(x-(-3))\\\\\Rightarrow\ y-1=\dfrac32(x+3)[/tex]
Required equation: [tex]y-1=\dfrac32(x+3)[/tex]

what is 1/2(10x +20y +10z) using the distributive property? also as an equivalent expression?
Answers
Answer:
5x+10y+5z.
Step-by-step explanation:
The given expression is
[tex]\dfrac{1}{2}(10x+20y+10z)[/tex]
We need to find the equivalent expression by using the distributive property.
By using the distributive property, the given expression can be written as
[tex]\dfrac{1}{2}(10x+20y+10z)=\dfrac{1}{2}(10x)+\dfrac{1}{2}(20y)+\dfrac{1}{2}(10z)[/tex]
[tex]=5x+10y+5z[/tex]
Therefore, the required expression is 5x+10y+5z.
True or false? If false give counterexample The product of a rational number and an integer is not an integer
Answers
Answer:
False
Step-by-step explanation:
Required
State if the product of rational numbers and integer is an integer
The statement is false and the proof is as follows
Literally, rational numbers are decimal numbers that can be represented as a fraction of two integers;
Take for instance: 0.2, 0.5, 2.25, etc.
When any of these numbers is multiplied by an integer, the resulting number can take any of two forms;
1. It can result to an integer:
For instance;
[tex]0.2 * 5 = 1[/tex]
[tex]0.5 * 4 = 2[/tex]
[tex]2.25 * 8 = 18[/tex]
2. It can result in a decimal number
For instance;
[tex]0.2 * 3 = 0.6[/tex]
[tex]0.5 * 5 = 2.5[/tex]
[tex]2.25 * 7 = 15.75[/tex]
From (1) above, we understand that the product can result in an integer.
Hence, the statement is false
a standard number cube has six labeled sides labeled 1-6. think about rolling a number cube one time. why is it just as likely that the cube will show and even number as an odd number
Answers
Answer:
This is because there are equal counts of both even and odd numbers
Step-by-step explanation:
Here in this question, we are concerned with stating the reason why it is likely that a standard number cube have the same probability for showing an even number as well as an odd number.
In the number cube, the odd numbers are 1,3 and 5. While the even numbers are 2,4 and 6.
From here, we can see that there are three set of each number types. What this automatically means is that the probability of selecting an even number will be equal to the probability of selecting an odd number. Thus, we can say that it is just as likely that the cube will show an even number as an odd number because each of the type of numbers have 3 values each.
2. A boy and his father played 26 games of checkers. For every game the boy lost, he gave his father 5 cents. For every game the boy won, his father gave him 8 cents. When all the games were played, neither had won nor lost anything. The number of games the boy won i
Answers
Answer: the boy won 10 games
Step-by-step explanation:
Let's call B as the number of games won by the boy, and F as the number of games won by the father.
We know that, there is a total of 26 games:
B + F = 26.
We know that in each game won by the boy, he wins 8 cents, for every game that the father wins, the boy losses 5 cents, and we know that at the end of the 26 games, the boy did not win or lose any money, so we have:
B*8 + F*(-5) = 0.
Then we have a system of equations:
B + F = 26
8*B - 5*F = 0.
The first step is isolating one of the variables. Let's start isolating F in the first equation:
B + F = 26
F = 26 - B.
Now we can replace this in the second equation:
8*B - 5*F = 0
8*B - 5*(26 - B) = 0
8*B + 5*B - 5*26 = 0
13*B = 5*26
B = 5*26/13 = 5*2 = 10
So the boy won 10 games (then the father won the other 16 games)

x = 19
Step-by-step explanation:
The angles of a triangle add to 180
U and S are equal since they are the base angles and UT and ST are equal
S + T + U = 180
x + 26 + 90 + x+26 = 180
Combine like terms
2x +142 = 180
Subtract 142 from each side
2x = 38
Divide each side by 2
2x/2 = 38/2
x = 19
Answer:
19
Step-by-step explanation:
x+26+x+26+90 = 180
2x + 52 = 90
2x = 38
x = 19

Question (1)
Umar drove his taxi in two parts;
1). Ipoh to Tapah
2). Tapah to Kuala Lumpur
Since, the formula to calculate the average speed = [tex]\frac{\text{Distance}}{\text{Time}}[/tex]
Total distance from Ipoh to Tapah = 60 km
Average speed to cover this distance = 100 km per h
Time taken to cover this distance = [tex]\frac{\text{Distance covered}}{\text{Speed}}[/tex]
= [tex]\frac{60}{100}[/tex]
= 0.6 hours
Total distance from Ipoh to Kuala Lumpur = 220 km per h
Average speed from Ipoh to Kuala Lumpur = 110 km per h
Time taken to cover the distance = [tex]\frac{220}{110}[/tex] = 2 hours
Distance from Tapah to Kuala lumpur = 220 - 60
= 160 km
Time taken to travel from Tapah to Kuala Lumpur = 2 - 0.6
= 1.4 hours
Average speed from Tapah to Kuala Lumpur = [tex]\frac{160}{1.4}[/tex]
= 114. 29 km per hour
Question (2).
Speed achieved by the leopard = 25.9 meter per sec.
Since, 25.9 meter = [tex]\frac{25.9}{1000}[/tex] km
= 0.0259 km
1 second = [tex]\frac{1}{3600}[/tex] hour
Therefore 25.9 meter per second = [tex]\frac{0.0259}{\frac{1}{3600} }[/tex]
= 0.0259 × 3600
= 93.24 km per hour

[tex] q = 2(3r + 8) [/tex]
Step-by-step explanation:
There are two variables, q and r in the expression given. To make r the independent variable, it simply means, make q the subject of the formula, so that variable q would be dependent on variable r. As r changes, q changes also.
Thus,
[tex] q - 10 = 6(r + 1) [/tex]
Open the parenthesis
[tex] q - 10 = 6r + 6 [/tex]
Add 10 to both sides
[tex] q - 10 + 10 = 6r + 6 + 10 [/tex]
[tex] q = 6r + 16 [/tex]

coefficient of the second term is 3
Step-by-step explanation:
-5x+3y -7z +10
There are 4 terms, -5x, 3y ,-7x, 10
The constant is the term without the variable ( letter)
The constant is 10
The third term is -7z
The coefficient is the number in front of the variable
The coefficient of the second term 3y is 3
For part a, we are asked how many terms does this expression have.
Well a term can be a number, a variable, or it can
even be a number times one or more variables.
So the terms would be -5x, +3y, -7z, and +10.
For part b, we are asked what is the constant.
Usually, constants are numbers all by themselves.
So here, the constant would be 10.
In part c, we are asked what is the third term.
Well, looking at the expression, we can see that -7z is the third term.
Finally, what is the coefficient of the second term.
The coefficient is the number before your variable.

66 units
46 units
O 33 units
38 units
Answers
Answer:
66
Step-by-step explanation:
The figure of triangle JKL is attached. JA = 9, AL = 10, and CK = 14.
According to two tangent theorem, the tangent to a circle that meets at the same point is equal to each other. Therefore:
AJ = BJ, AL = CL, CK = BK.
Since AJ = 9, BJ = AJ = 9
AL = 10, CL = AL = 10
CK = 14, BK = CK = 14.
Therefore the lengths of the triangle sides are:
JL = AJ + AL = 9 + 10 = 19
JK = BJ + BK = 9 + 14 = 23
KL = CL + CK = 14 + 10 = 24
The perimeter of the triangle is the sum of all its sides, it is given as:
Perimeter = JL + JK + KL = 19 + 23 + 24 = 66

As we can see each term contains 25x
The greatest common factor is 25x
25x( 4x -10y+3)
Answer:
25x
Step-by-step explanation:
GCF means the greatest common factor.
First, we write the factors of these numbers.
=> 100x^2 = 2 * 2 * 5 * 5 * X * X
=> 250xy = 5 * 5 * 5 * 2 * X * Y
=> 75x = 5 * 5 * 5 * x
=> Next, we need to take the numbers that come in all sets.
=> 5 , 5 , x
Next, we multiply these numbers.
=> 25x
So, the GCF of these numbers are 25x

Answers
Answer:
The cost of the laptop is $769.10Step-by-step explanation:
In this problem we are required to find the cost of the laptop when 9.25% of the cost is added as tax
we are given that the tax rate is 9.25% of the initial cost
and the initial cost is $703.98
let us calculate 9.25% of $703.98
(9.25/100)* 703.98= 0.0925*703.98= $65.12
Hence the charges for tax is $65.12
The total cost of the laptop when tax is included is
the initial cost Plus the tax charges= $703.98+$65.12= $769.098
