Answer:
The line with be duchess with shading below.
None of the above
Step-by-step explanation:
The correct inequality expression is;
y < 2x+3
Note that the inequality sign between the expressions is the one that will determine the nature of the line.
Since the sign is not containing the "equal to" sign this means that the line will be broken(duchess).
Since it is "less than", the shading will be below the line.
Considering the given option, None of the option is correct
For the inequalities
[tex]\rm\bold{ y < 2x+3 ......(1)} \\\\\rm \bold{y > 2x +3....(2)}}[/tex]
For Case (1)
Option d will be chosen as correct option
hence " none of these" will be the answer
For Case (2)
Option b will be chosen as correct option
hence " The line with be duchess with shading above " will be the answer
Since the sign of the inequality here is not clear let us consider 2 cases that are represented by equation (1) and equation (2)
[tex]\rm y < 2x+3 ......(1) \\y > 2x +3....(2)[/tex]
Considering case 1 as represented by equation (1)
The y values are always less than the expression for the line 2x+3 hence points on the line [tex]\rm y = 2x +3[/tex] will not be included for this inequality hence the line will be duchess with area below the line.
So in this case option d will be chosen as correct option
hence " none of these" will be the answer
Similarly now considering case 2 as represented by equation (2)
The y values are always more than the expression for the line 2x+3 hence
points on the line [tex]\rm y = 2x +3[/tex] will not be included for this inequality hence the line will be duchess with area above the line.
So in this case option b will be correct.
Note :
The lines will be solid when the inequalities in equation (1) and (2) also include equal to sign.
That is for lines to be solid
the inequalities will be of type
[tex]\rm y \leq 2x+3 \\y \geq 2x +3[/tex]

0 - 1/64
0 1/64
0 2
0 64
The correct answer is,
[tex] \frac{1}{64} [/tex]
Answer:
1/64
Step-by-step explanation:
when exponents are separated by parentheses, multiply them
so (2³)^-2 = 2^-6
whenever an exponent is negative, change into fraction form with one as the numerator and the other term goes into the denominator and the exponent now becomes positive
2^-6 = [tex]\frac{1}{2^6}[/tex] = [tex]\frac{1}{64}[/tex]

Which one is closer to 1 whole , 1 1/4 , 1 1/12 , 1 5/12 ? explain
Answer:
1 1/2
Step-by-step explanation:
We need to convert all of these into one denominator. 1 1/4 needs to be converted into 12ths. 4 x 3 = 12 1 x 3 = 3. Our new fraction instead of 1 1/4 is 1 3/12.
Which is closer to the whole number?
1 1/12 is 1/12 away from a whole number
1 3/12 is 3/12 away from a whole number
1 5/12 is 5/12 away from a whole number

2. The sum of two numbers is 52. The
difference of the two numbers is 6.
What are the numbers?
Answer:
29 and 23
Step-by-step explanation:
Step 1: rewrite the sentences as equations:
equation 1: x+y=52
equation 2: x-y=6
Step 2: add those two equations together to get:
2x=58
x=29
Step 3: substitute x in one of the first equations to get y:
29-y=6
y=23
Step 4: Check with the other equation:
x+y=52
29+23=52✔
The diagram shows a piece of cheese in the shape of the triangular prism.Work out the area of the cling film needed to cover the cheese
Answer:
488.4 cm²
Step-by-step explanation:
Area of cling film needed = surface area of the triangular prism = 2(B.A) + P×H
Where,
B.A = triangular base area = ½*base*height
height = 10.5 cm
base = √(13.7² - 10.5²) = √77.44 = 8.8 cm
B.A = ½*8.8*10.5 = 46.2 cm²
P = perimeter of the triangular base = 10.5 + 13.7 + 8.8 = 33
H = height of prism = 12 cm
Surface area of triangular prism = 2(46.2) + 33*12
= 92.4 + 396
= 488.4 cm²

April, May and June have
90
sweets between them. May has three-quarters of the number of sweets that June has.
April has two-thirds of the number of sweets that May has. How many sweets does June have?
help
Answer:
A
Step-by-step explanation:
The month of June has 40 sweets
Let the number of sweets in the month of June be P
Given that April, May and June collectively have 90 sweets
Given that May has three quarters of number of sweets as that of June
So we can write
[tex]\rm Number\; of \; sweets\; in \; May = \dfrac{3P}{4 } .......(1) \\[/tex]
Similarly it is given that April has two third of sweets as that of May month and hence we can write
[tex]\rm Number\; of\; sweets \; in \; April = \dfrac{2}{3} \times \dfrac{3P}{4} = P/2 ......(2)\\[/tex]
As the total number of sweets in April, May and June is 90
Let the number of sweets in May be "M" and in April be "A"
We can write the following equation and solve it further
[tex]\rm M + A + P = 90\\From \;equations \; (1) \; and \; (2) \\[/tex]
[tex]\rm P + 3P/4 + P/2= 90\\\\2.25 \; P = 90\\P = 40[/tex]
So we can conclude that the month of June has 40 sweets

Write 36 + 60 as a product using the GCF as one of the factors.
Answer:
12(3+5)
Step-by-step explanation:
You factor out 12 because it is the GCF, then you divide 36 and 60 by 12.
36 + 60 as a product using the GCF as one of the factors is 12(3 + 5).
What are GCF and distributive property?The GCF of two or more than two numbers is the highest number that divides the given two numbers completely.
We also know that distributive property states a(b + c) = ab + ac.
Given, 36 + 60 now the common factors of 36 and 60 are 2, 3, 6, 12
∴ The GCF of 36 and 60 is 12.
So, 36 + 60 as a product can be written as
36 + 60.

What is the completely factored form of this polynomial?
81x4 − 16y4
Answer:
( 9 x^ 2 + 4 y ^2 ) ( 3 x + 2 y ) ( 3 x − 2 y )
The completely factored form of the polynomial 81x^4 - 16y^4 is:
(3x + 2y)(3x - 2y)(9x^2 + 4y^2)(9x^2 - 4y^2)
Determining the completely factored formApply the difference of squares formula:
(9x^2)^2 - (4y^2)^2
Factor the difference of squares:
(9x^2 + 4y^2)(9x^2 - 4y^2)
Apply the difference of squares formula again:
(3x)^2 + (2y)^2
(3x)^2 - (2y)^2
Factor the difference of squares:
(3x + 2y)(3x - 2y)
Putting it all together, the completely factored form of the polynomial 81x^4 - 16y^4 is:
(3x + 2y)(3x - 2y)(9x^2 + 4y^2)(9x^2 - 4y^2)
