Answer:
n = -8Step-by-step explanation:
For two lines to be parallel, they must have the same slope
Get the slope of each line
For L1;
m1 = -2-4/1-n
m1 = -6/1-n
For L2;
m2 = 5-3/1-4
m2 = 2/-3
m2 = -2/3
Since they have the same slope, m1 = m2
-6/1-n = -2/3
6/1-n = 2/3
Cross multiply
2(1-n) = 6(3)
2-2n = 18
-2n = 18 - 2
-2n = 16
n = -16/2
n = -8
Hence the value of n is -8

Answer:
Step-by-step explanation:
Total weight of the barricade is 310 kg using 8 boxes of books
Each box of books weighs 30 kg
We need to determinethe weight of the table in order write the proper equation
Total wieght of the barricade = Table Weight + Book Weight
solving for Table Weight substract Book Weight from both sides
Total wieght of the barricade - Book Weight = Table Weight
310 - 8(30) = Table Weight
310 - 240 = Table Weight
70 = Table Weight
Total wieght of the barricade = Table Weight + Book Weight
W = 70 + 30x where x is the number of boxes
Which graph best represents a quadratic function that has only one zero?
Answer:
B
Step-by-step explanation:
A has 2 it crosses the x axis 2x
B Has 1.
C has 2
D has none since it never touched the x axis
Option B is correct.
Quadratic function :If the graph of quadratic function crosses x - axis at two points then that function has two zeros.
If the graph of quadratic function crosses x - axis at only one point then that function has only one zero.If the graph of quadratic function do not crosses x - axis at any point then that function has no zeros.From given option, It is observed that option B graph crosses x- axis at only one point.Therefore, Option B graph represent a quadratic function that has only one zero.

Sara was thinking of a number. Sara adds 12, then divides by 7 to get an answer of 11. What was the original number?
Answer:
65
Step-by-step explanation:
Do the opposite of what the question gives you.
Sara has the number 11. She divided by 7, so you would multiply by 7:
11 x 7 = 77
Next, Sara added 12, so you will subtract by 12:
77 - 12 = 65
65 is the number Sara was thinking of.

which of the following is a difference of cubes?
a. 3x^9-64y^3
b. 15x^21-64y^3
c. 27x^15-9y^3
d. x^6+27y^9
Answer:
D: x^(6) + 27y^(9)
Step-by-step explanation:
A) 3x^(9) - 64y^(3)
The first term is raised to the power of 9 and has a coefficient which cannot also be expressed as a cube while the second term is raised to the power of 3 but has a coefficient that can be expressed as a cube. Thus the entire equation cannot be simplified to cubes as the first term cannot be expressed a cube.
B) 15x^(21) - 64y^(3)
Similar to the reason given in A above, the first term cannot be expressed as a cube.
C) 27x^(15) - 9y^(3)
In this one, the first term can be expressed as a cube while the second one cannot be expressed as a cube because 9 cannot be expressed as a cube.
D) x^(6) + 27y^(9)
This can be expressed as;
(x²)³ - (-3y³)³
This is therefore a difference of cubes
A, B, and C are polynomials, where A = n, B = 2n + 6, and C = n2 – 1. What is AB – C in simplest form?
–n2 + 3n + 5
n2 + 6n + 1
2n2 + 6n – 1
3n2 + 5
Answer:
n^2 + 6n + 1
Step-by-step explanation:
Firstly, we have to evaluate AB
What we have to do is to multiply A and B
We have this as;
n(2n + 6) = 2n^2 + 6n
Now, we have to subtract the value of C from here and that is;
(2n^2 + 6n) - (n^2 - 1)
2n^2 + 6n - n^2 + 1
= 2n^2 -n^2 + 6n + 1
= n^2 + 6n + 1

Which inequality describes the relationship between points A and B on the number line?
Answer:
B > A
Step-by-step explanation:
B and A are both in between 0 and 1 on a number line.
On a number line, the further right you go, the higher numerical values get, and the further left - vice versa.
Anyhow, B is further to the right, as well as closer to 1 than A is, so we can assume that B is the greater number.

Eric goes to town with £15. He spends £8.50 on a new scarf.
He meets his nan who gives him £20 and tells him to take £10 of it home for his sister
Eric then sees a jumper he likes which costs £18.
If Eric buys the jumper, will he still have £10 to give it to his sister?
Show how you worked out your answer.
Answer: No he would have 8.5$
Step-by-step explanation:
15 - 8.50 = 6.50$ + 20$ = 8.5 so no he would be 1.5$ short
If Eric buys the jumper, he will not have £10 left to give to his sister.
To determine if Eric will still have £10 to give to his sister after buying the jumper, we need to calculate his remaining balance.
Initial amount Eric has = £15
Cost of the scarf = £8.50
Amount received from his nan = £20
Cost of the jumper = £18
Amount to give to his sister = £10
First, let's calculate Eric's remaining balance after buying the scarf:
Remaining balance = Initial amount - Cost of the scarf
Remaining balance = £15 - £8.50
Remaining balance = £6.50
Next, let's calculate Eric's balance after receiving money from his nan:
Total balance = Remaining balance + Amount received from nan
Total balance = £6.50 + £20
Total balance = £26.50
Now, let's check if Eric can still afford to buy the jumper:
If Eric buys the jumper:
New balance = Total balance - Cost of the jumper
New balance = £26.50 - £18
New balance = £8.50
The new balance after buying the jumper is £8.50. As we can see, this amount is less than the £10 Eric needs to give to his sister.
Therefore, if Eric buys the jumper, he will not have £10 left to give to his sister.
