Answer:
30p^3-36p. Also, my day was niceeeee.
Step-by-step explanation:
To simplify this, we have to use the distributive property. First, you do 6 times 5p^3, and then you get 30p^3. Then you do 6 times 6p, which gives you 36p. So, the final answer would be 30p^3-36p.
Gloria decides to buy 4 ferns, 2 Palms, 10 Lilies and 8 shrubs. To show the total
cost of the plants as an expression, first set up an expression showing how the
distributive property can shorten the process and then simplify it.
Step by step
Answer:
[tex]Total Plants = 4F + 2P + 10L+ 8S[/tex]
[tex]Total Plants = 2(2F + P + 5L+ 4S)[/tex] --- Distributive property
Step-by-step explanation:
Given
Ferns = 4
Palms = 2
Lillies = 10
Shrubs = 8
Required
Show the total cost of plants as an expression
Shorten it using the distributive property
First, represent Ferns with F; Palms with P; Lilies with L and Shrubs with S;
So, 4 Ferns = 4F
2 Palms = 2P
10 Lilies = 10L
8 Shrubs = 8S
Total Plants = Summation of the above parameters
[tex]Total Plants = 4F + 2P + 10L+ 8S[/tex]
The above expression represents the total plants bought;
Now, to apply the distributive property; we simply look for a common factor;
In this case, the common factor is 2;
So, [tex]Total Plants = 4F + 2P + 10L+ 8S[/tex] becomes
[tex]Total Plants = 2(\frac{4F}{2} + \frac{2P}{2} + \frac{10L}{2}+ \frac{8S}{2})[/tex]
[tex]Total Plants = 2(2F + P + 5L+ 4S)[/tex]
There are 25 students in a class. 16 of those students are boys. What percent of the class are girls?
The percent of girls in the class is ____ %
Answer:
36 %
Step-by-step explanation:
9 girls = 36%
25 students = 100
Answer:
Step-by-step explanation:
25 students in a class and 16 out of the 25 students in the class are girls. There are 9 boys in the class because "25-9=16"
HOW TO SOLVE If we know that 9 out of the 25 students in the class are girls, we can represent it as the fraction . Next, we divide 35 by 9 to get a quotient of 0.36 and then multiply by 100 to get our percent of girls in the class which is 36%

Answer:
Step-by-step explanation:
Solve the given 3x + 5y = 2 for y. This will automatically indicate the slope of the line.
Subtracting 3x from both sides of this equation, we get:
5y = -3x = -3x + 2.
Dividing both sides by 5 yields y = (-3/5)x + 2/5.
The slope of the given line is -3/5. The y-intercept of this line is (0, 2/5).

Apply addition property of equality
Adding '6' on both sides , we get
3 x - 6 + 6 = 12 +6
3 x = 18
Step(ii):-
Apply Division property of equality
Dividing '3' on both sides , we get

Twice a number plus three times a second number is negative one. The first number plus four times the second number is two.
Answer:
Step-by-step explanation:
The first number is -2 and the second number is 1
Answer:
The first number is -2 and the second number is 1.
Step-by-step explanation:
2n + 3s = -1
(n + 4s = 2)-2 Multiply by -2 to cancel the n
2n + 3s = -1
-2n - 8s = -4 Add these equations together
-5s = -5 Divide both sides by -5
s = 1
Plug this into the first equation to find the value of n
2n + 3(1) = -1 Multiply
2n + 3 = -1
- 3 - 3 Subtract 3 from both sides
2n = -4 Divide both sides by 2
n = -2

Answer:
[tex]y - x = 2[/tex]
Step-by-step explanation:
Given
Points (-2,0) and (-3,-1)
Required
Equation of Line
The first step is to determine the slope of the line; using the following formula
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]Where\ (x_1,y_1) = (-2,0)\ and\ (x_2,y_2) = (-3,-1)[/tex]
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex] becomes
[tex]m = \frac{-1 -0}{-3 - (-2)}[/tex]
[tex]m = \frac{-1}{-3 +2}[/tex]
[tex]m = \frac{-1}{-1}[/tex]
[tex]m = 1[/tex]
The next is to determine the equation of the line using any of the points
The formula is as thus;
[tex]m = \frac{y - y_1}{x - x_1}\ or\ m = \frac{y - y_2}{x - x_2}[/tex]
Using [tex]m = \frac{y - y_1}{x - x_1}[/tex]
[tex]Where\ (x_1,y_1) = (-2,0)\ and\ m =1[/tex]
[tex]1 = \frac{y-0}{x - (-2)}[/tex]
[tex]1 = \frac{y-0}{x +2}[/tex]
[tex]1 = \frac{y}{x +2}[/tex]
Multiply both sides by x + 2
[tex](x+2)*1 = \frac{y}{x +2} * (x+2)[/tex]
[tex](x+2)*1 = y[/tex]
[tex]x+2 = y[/tex]
[tex]y = x + 2[/tex]
Subtract x from both sides
[tex]y - x = x - x +2[/tex]
[tex]y - x = 2[/tex]
Hence, the equation of the line in standard form is [tex]y - x = 2[/tex]

On a coordinate plane, a square and a point are shown. The square has points R prime (negative 8, 1), S prime (negative 4, 1), T prime (negative 4, negative 3), and U prime (negative 8, negative 3). Point S is at (3, negative 5). Square RSTU is translated to form R'S'T'U', which has vertices R'(–8, 1), S'(–4, 1), T'(–4, –3), and U'(–8, –3). If point S has coordinates of (3, –5), which point lies on a side of the pre-image, square RSTU? (–5, –3) (3, –3) (–1, –6) (4, –9)
Answer:
(–1, –6)
Step-by-step explanation:
Given that S(3, –5) was translated to S'(–4, 1), the transformation rule is (x-7, y+6). Then, the coordinates of square RSTU are:
R'(–8, 1) -> (-8+7, 1-6) -> R(-1, -5)
S'(–4, 1) -> (-4+7, 1-6) -> S(3, -5)
T'(–4, –3) -> (-4+7, -3-6) -> T(3, -9)
U'(–8, –3) -> (-8+7, -3-6) -> U(-1, -9)
The point (–1, –6) lies on the segment RU
The point that lies on a side of the pre-image is mathematically given as
x=(-1,-6)
What is a Pre-Image?A pre-image is simply a the group of chosen elements from a mapped domain to give a given subset of the codomain.
What points can be found on the pre-image, square RSTU?Question Parameter(s):
which has vertices
R'(–8, 1),
S'(–4, 1),
T'(–4, –3),
U'(–8,
Generally, the equation for the transformation is mathematically given as
(x-7, y+6).
Therefore
R'(–8, 1) --> (-8+7, 1-6)
R'(–8, 1) --> R(-1, -5)
S'(–4, 1) -=> (-4+7, 1-6)
S'(–4, 1)-> S(3, -5)
T'(–4, –3) --> (-4+7, -3-6)
T'(–4, –3 -> T(3, -9)
U'(–8, –3) --> (-8+7, -3-6)
U'(–8, –3)-> U(-1, -9)
In conclusion, point S with coordinates of (3, –5) lies within RU
x=(-1,-6)

in the following triangle theta=60.Find the values of the angles of the angles B and B'
Answer:
A. B = 64.13° or B' = 115.87°
Step-by-step explanation:
The given angle is opposite the shortest of the given sides, so there are two possible solutions using the Law of Sines. Either way, we have ...
sin(B)/16 = sin(θ)/15.4
B = arcsin(16/15.4·sin(60°)) ≈ arcsin(0.899767)
B = 64.13° or B' = 180° -64.13° = 115.87°
Explain the special pattern for sketching a parabola
Answer:
the parabola can be written as:
f(x) = y = a*x^2 + b*x + c
first step.
find the vertex at:
x = -b/2a
the vertex will be the point (-b/2a, f(-b/2a))
now, if a is positive, then the arms of the parabola go up, if a is negative, the arms of the parabola go down.
The next step is to see if we have real roots by using the Bhaskara's equation:
[tex]x = \frac{-b +-\sqrt{b^2 -4ac} }{2a}[/tex]
Now, draw the vertex, after that draw the values of the roots in the x-axis, and now conect the points with the general draw of the parabola.
If you do not have any real roots, you can feed into the parabola some different values of x around the vertex
for example at:
x = (-b/2a) + 1 and x = (-b/2a) - 1
those two values should give the same value of y, and now you can connect the vertex with those two points.
If you want a more exact drawing, you can add more points (like x = (-b/2a) + 3 and x = (-b/2a) - 3) and connect them, as more points you add, the best sketch you will have.
