Answer:
y=3x+3
Step-by-step explanation:
Let's solve for y.
2y−6=6x
Step 1: Add 6 to both sides.
2y−6+6=6x+6
2y=6x+6
Step 2: Divide both sides by 2.
2y /2 = 6x+6 /2
y=3x+3
brainliest please?Answer:
y=3x+3
Step-by-step explanation:
add 6 to both sides and then divide both sides by 2
b) In a exam, Biraj got 350 marks and failed by 20 marks lf the percentageof pass marks is 40%, what is the full marks
Answer:
925 marks.
Step-by-step explanation:
AS Biraj had 20 less marks then the 40% pass mark must be 350+20 = 370.
370 is equivalent to 40%
So 100% = 100*370 / 40
= 925 marks.

A local bakery charges $2.75 per cupcake.
Which equation best represents y, the total cost
of x number of cupcakes?
A.
y = 2.75 + x
B.
y = 2.75x
C.
x = 2.75y
D.
x = 2.75 + y
Mond
Answer:
B
Step-by-step explanation:
y = 2.75x
have a great day
Answer:
B. y = 2.75x
Step-by-step explanation: Since Y represents the total cost that means that the total cost is how ever many cupcakes one were to buy. Since each cupcake is $2.75 and you are buying X amount of cupcakes, the total would be 2.75 ~multiply~ X. Thus, giving you your final answer of y=2.75x.

Answer:
a = 3b = -18Step-by-step explanation:
Using the least common denominator, we have ...
[tex]2-\dfrac{x+1}{x-2}-\dfrac{x-4}{x+2}\\\\=\dfrac{2(x-2)(x+2)-(x+1)(x+2)-(x-4)(x-2)}{(x-2)(x+2)}\\\\=\dfrac{2(x^2-4)-(x^2+3x+2)-(x^2-6x+8)}{x^2-4}\\\\=\dfrac{(2-1-1)x^2+(-3+6)x+(-8-2-8)}{x^2-4}=\boxed{\dfrac{3x-18}{x^2-4}}[/tex]
The values of a and b are ...
a = 3
b = -18
Which statement best describes f(x)=

A. 6 is in the domain of f(x) but not in the range of f(x).
B. 6 is not in the domain of f(x) but is in the range of f(x).
C. -6 is in the domain of f(x) and in the range of f(x).
D. 6 is neither in the domain of f(x) nor in the range of f(x).
Answer:
D
Step-by-step explanation:
the domain of this is x>=7
the range is x<=1
so 6 is in neither

The midpoint of AB isM(2,5). If the coordinates of A are (−3,6), what are the coordinates of B?
Answer:
(7,4)
Step-by-step explanation:
Midpoint Formula = [tex](x_{1} + x_{2}/2)=[/tex] x coordinate of midpoint
same for y coordinate of midpoint
so
2=-3+x/2
4=-3+x
x=7
for y
5=6+y/2
10=6+y
y=4
therefore B(7,4)
Ruchi covers 3.25 Kilometres in 50 minutes. How much distance will she cover in Metres in 94 minutes?
Answer:
Distance covered by Ruchi = 61.1 km
Step-by-step explanation:
Formula of the Speed is given by,
Speed = [tex]\frac{\text{Distance covered}}{\text{Time taken}}[/tex]
Since, Ruchi coves distance = 3.25 km
Time taken to cove this distance = 50 minutes
Therefore, speed of Ruchi = [tex]\frac{3.25}{50}[/tex]
= 0.65 km per minute
Therefore, distance covered by Ruchi in 94 minutes,
0.65 = [tex]\frac{\text{Distance covered}}{94}[/tex]
Distance covered = 0.65 × 94
= 61.1 km

Note: Round your answer to the nearest tenth.
Given:
In a right angle triangle ABC, [tex]m\angle B=90^\circ, BC=x, AC=11, m\angle C=41^\circ[/tex].
To find:
The value of x to the nearest tenth.
Solution:
In a right angle triangle,
[tex]\cos\theta =\dfrac{Adjacent}{Hypotenuse}[/tex]
In the given right angle triangle ABC,
[tex]\cos \angle C =\dfrac{BC}{AC}[/tex]
[tex]\cos (41^\circ) =\dfrac{x}{11}[/tex]
[tex]11(0.7547) =x[/tex]
[tex]8.3017 =x[/tex]
Round the answer to the nearest tenth.
[tex]x\approx 8.3[/tex]
Therefore, the value of x is 8.3 units.

In cabbage butterflies, white wings (W) are dominant to yellow wings (w). A heterozygous butterfly mates with a butterfly that has yellow wings. Complete the Punnett square and then list the percentages of the expected genotypes for their offspring.
Answer:
(a)
[tex]\begin{array}{ccc}{} & {W} & {w} & {w} & {Ww } & {ww } & {w} & { Ww} & {ww } \ \end{array}[/tex]
(b)
[tex]White = 50\%[/tex]
[tex]Yellow = 50\%[/tex]
Step-by-step explanation:
See attachment for initial punnet square
Solving (a): Complete the square
Initially, we have:
[tex]\begin{array}{ccc}{} & {W} & {w} & {w} & { } & { } & {w} & { } & { } \ \end{array}[/tex]
To complete the square, we simply write the letter at the column and the letter at the row in each cell;
So, we have:
[tex]\begin{array}{ccc}{} & {W} & {w} & {w} & {Ww } & {ww } & {w} & { Ww} & {ww } \ \end{array}[/tex]
Solving (b): Percentage of each
From the question, we understand that W are dominant to w.
So:
[tex]Ww = White[/tex]
[tex]ww = Yellow[/tex]
From (a) above
[tex]Ww = 2[/tex]
[tex]ww = 2[/tex]
[tex]Total = 4[/tex]
So, the percentage of each is:
[tex]White = \frac{Ww}{Total} * 100\%[/tex]
[tex]White = \frac{2}{4} * 100\%[/tex]
[tex]White = 0.5 * 100\%[/tex]
[tex]White = 50\%[/tex]
[tex]Yellow = 100\% - White[/tex] --- Complement rule
[tex]Yellow = 100\% - 50\%[/tex]
[tex]Yellow = 50\%[/tex]

Find the potential solution to the equation
log (2-x) = log (-5x - 18).
x=
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the concept of logarithms.
Since here the log is on both sides, we take antilog on both sides, so we get as,
==> 2-x = -5x - 18
==> -x + 5x = -18 -2
==> 4x = -20
==> x = -20/4
==> x = -5
hence, x = -5

The perimeter of a rectangular garden is 68 feet. The length
of the garden is 2 feet more than double the width. What is the
width of the garden?
Answer:
10 2/3 ft or approximately 10.67 ft
Step-by-step explanation:
Let the width = w
The length is L = 2w + 2.
The perimeter is:
P = 2(L + w)
P = 2(2w + 2 + w)
P = 2(3w + 2)
P = 6w + 4 = 68
6w = 64
w = 64/6
w = 32/3 = 10 2/3
Answer: 10 2/3 ft or approximately 10.67 ft
If you place a 39-foot ladder against the top of a building and the bottom of the
ladder is 33 feet from the bottom of the building, how tall is the building? Round to
the nearest tenth of a foot.
The ladder and the top of the building form a right triangle
The building is 20.8 feet tall
`How to determine the height of the building?The given parameters are:
Length of ladder, L = 39 feetHorizontal distance (b) = 33 feetThe height (h) of the building is calculated using the following Pythagoras theorem
L^2 = b^2 + h^2
So, we have:
39^2 = 33^2 + h^2
Evaluate the exponent
1521 = 1089 + h^2
Rewrite as:
h^2 = 1521 - 1089
h^2 = 432
Take the square root of both sides
h = 20.8
Hence, the building is 20.8 feet tall

If the course must be at least 3 miles but no more than 3.2 miles in length, what is the smallest and the largest number of feet they must walk in order to fulfill the requirements?
1 mile 5,280 feet.
Smallest:
Largest:
Answer:
Smallest: 15,840 ft
Largest: 16,896 ft
Step-by-step explanation:
1 mi = 5,280 ft
Setup proportion to solve for the smallest:
[tex]\frac{1mi}{5,280ft} =\frac{3mi}{xft}[/tex]
Do butterfly method and you should get this:
[tex]xft=3(5280)\\x=15,840ft[/tex]
Setup proportion to solve for the largest:
[tex]\frac{1mi}{5,280ft} =\frac{3.2mi}{xft}[/tex]
Butterfly method:
[tex]xft=3.2(5280)\\x=16,896ft[/tex]

Cube numbers between 100 and 400
Answer with step-by-step explanation:
Let us find the perfect cubes between 1 to 100.
We know that, 1
3
=1,2
3
=8,3
3
=27,4
3
=64 and the rest numbers i.e. 4,5,6,.... have their cubes greater than 100.
So, only these four numbers have their cubes between 1 to 100.
Thus, there are 4 perfect cubes from 1 to 100.
Now, let's find the cubes between −100 to 0
We know, 0
3
=0,(−1)
3
=−1,(−2)
3
=−8,(−3)
3
=−27,(−4)
3
=−64 and the rest numbers have their cubes less than −100
So, only these 5 numbers have their cubes between −100 to 0 and 4 perfect cubes are there from 1 to 100.
Thus, there are 9 perfect cubes from −100 to 100.
