Answer:
4y + 7
Step-by-step explanation:
Simplify. Use the distribution method, and follow PEMDAS.
PEMDAS is the order of operation. It stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
Distribute 4 to all terms within the parenthesis. In this case, you are multiplying 4 to all the terms:
4(y + 3) = (4 * y) + (4 * 3) = 4y + 12
Next, combine like terms (terms with the same amount of variables);
4y + 12 - 5
4y + (12 - 5)
4y + 7
4y + 7 is your simplified expression.

Answer:
16km
Step-by-step explanation:
Since its a right angle triangle we can use the pythogorean theorem, which is a^2 + b^2 = c^2
So if we apply it to this situation we get,
12^2 + b^2 = 20^2
144 + b^2 = 400
b^2= 400 - 144
b^2= 256
b= 16
So the answer is 16km
Hope this helped :)

3^-6 x (3^4 divided by 3^0)^2. simplfyed i need it quick im about to guess
Answer:
Step-by-step explanation:
first the parenthesis
3^4/3^0=3^4
anything raised to the power of 0 is 1
(3^4)^2=3^8 you multiply the powers
3^-6 * 3^8= 3^(-6+8)=3^2
Thhe simplified form of the expression is 9
Indices are expressed as power or exponent which is raised to a number or a variable.
According to the law of indices
[tex]a^n \times a^m = a^{n+m}\\a^n \div a^m = a^{n-m}[/tex]
Given the expression
[tex]3^{-6} \times (\dfrac{3^4}{3^0} )^2[/tex]
This can also be expressed as:
[tex]=\dfrac{1}{3^6} \times (\frac{3^4}{1})^2 \ (3^0 =1)\\= \dfrac{1}{3^6} \times 3^8\\=\dfrac{3^8}{3^6}\\=3^{8-6}\\=3^2\\=9\\[/tex]
This shows that the simplified form of the expression is 9

Your family is putting in a rectangular pool in the back yard. The pool's perimeter equals 28 feet. The contractor want the length to equal 5 more feet than 3 times the width. What will the width of your garden be?
Answer:
2.25 ft
Step-by-step explanation:
Perimter= 28ft
W= x ft
L= 3x+5
but
P=2L+2W
substitute
28=2*(3x+5)+2x
28=6x+10+2x
collet like terms
28=8x+10
28-10= 8x
18=8x
divide both sides by 8
x= 18/8
x=2.25 ft
Hence the width is 2.25 ft
b) The cost price of an article was Rs 4000.Find the marked price of the
article so that there will be a profit of 20% after allowing a discount of
20%. show process
Answer:
Market price = Rs. 6,000
Step-by-step explanation:
Given:
Cost price = R.s 4,000
Profit after discount = 20%
Discount = 20%
Find:
Market price
Computation:
Sales price = Cost price[1+Profit after discount]
Sales price = 4,000[1+20%]
Sales price = 4,800
Market price = Sales price[100/(100 - Discount)]
Market price = 4,800[100/(100 - 20%)]
Market price = Rs. 6,000

What is the equation of the function shown in the table?
Input x -2 -1 0 1 2
Output y -3 -1 1 3 5
y = - 1/2 x - 1
y = 2x + 1
y = 2x - 2
y = -2x + 1
Answer:
y = 2x + 1
Step-by-step explanation:
According to the table:
+1 +1 +1 +1
[x] -2 -1 0 1 2
[y] -3 -1 1 3 5
+2 +2 +2 +2
y = mx + b
b is y when x = 0
m is the change in y divided by the change in m = ∆y/∆x or slope.
+2/+1 = 2 = m
y = 1 when x = 0 so b = 1
therefore y = 2x + 1
What is the equation of the line in slope-intercept form?
Write your answer using integers, proper fractions, and improper fractions in
simplest form
Answer:
The equation of the line in the slope-intercept form will be:
y = -7xStep-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
m is the slope b is the y-interceptFrom the attached graph, taking two points
(0, 0)(-10, 70)Finding the slope between (0, 0) and (-10, 70)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(0,\:0\right),\:\left(x_2,\:y_2\right)=\left(-10,\:70\right)[/tex]
[tex]m=\frac{70-0}{-10-0}[/tex]
[tex]m=-7[/tex]
Determining the y-intercept:
We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
From the graph, it is clear that:
at x = 0, y = 0
Thus, the y-intercept b = 0
Now, substituting m = -7 and b = 0 in the slope-intercept form
y = mx+b
y = -7x + 0
y = -7x
Therefore, the the equation of the line in slope-intercept form will be:
y = -7xJanelle flies her kite several feet in the air. She then reels the kite in at a constant number of feet per minute.

Answer:
m∠AYB = 85°
m∠C = 50°
Step-by-step explanation:
By is the angle bisector of ∠ABC,
Therefore, m∠1 = m∠2 = 30°
m∠3 = 35°
m∠AYB + m∠YAB + m∠ABY = 180°
m∠AYB = 180° - [(m∠1 + m∠2) + m∠3]
= 180° - [(30° + 30°) + 35°]
= 180° - 95°
= 85°
m∠A + m∠B + m∠C = 180°
2(30°) + 2(35)° + m∠C = 180°
60° + 70° + m∠C = 180°
m∠C = 180° - 130°
m∠C= 50°

10. Find the width of the canyon.
13.
width = ?
22 m
15 m
160 m
I need help asap
Answer:
Therefore, the width of the canyon is 109.09 meters.
Step-by-step explanation:
* 160/22 = k (Scale Factor)
7.2727 = k
* Let x be the width of the canyon
x / 15 = k
x / 15 = 7.2727
x = 7.2727 (15)
x = 109.09 m
The width of the canyon is 109.09m.
The calculation is as follows:Here we assume x be the width of the canyon.
The k(Scale factor) should be
= [tex]160 \div 22[/tex]
k = 7.2727
So,
[tex]x \div 15 = k\\\\ x \div 15 = 7.2727[/tex]
x = 109.09 m
