peta has 4 friends now. last year she had 12. what is the percent of change?
Answer:
we simply see 4 has multiplied by -3
-12 = 4 x -3
This becomes -300%
We then add the 100 = initial amount onto a negatove percentage = -300 +100 = -200% change.
Step-by-step explanation:
3.00 x 4 = 12
4 + 8 = 12
4 x -2.00 = -8 being the change. The answer is -2.00 = -200%
Shows part of the answer and proves the answer is -200%

Answer:
x=35
Step-by-step explanation:
When a is parallel to b, the two angles will add to 180
x+ 3x+40=180
Combine like terms
4x+40 =180
Subtract 40 from each side
4x= 180-40
4x= 140
Divide by 4
4x/4 = 140/4

If g(x) = -4x + 5, find g(x+4).
Answer:
g(x + 4) = -4x - 11
Step-by-step explanation:
Since g(x) = -4x + 5, g(x + 4) = -4(x + 4) + 5
g(x + 4) = -4x - 11
Simplify the following expression 3^2/5 x 3^-7/5. I think it is 1/3. 3^-5/5
Answer:
1/3
Step-by-step explanation:
3^2/5 x 3^-7/5
We know that a^b* a^c = a^(b+c)
3^(2/5 -7/5)
3^ (-5/5) = 3^ -1
We know that a^-b = 1/ a^b
3^-1 = 1 / 3
why are triangles congruent ?
Explanation:
Basically triangles are congruent when they have the same shape and size.
Two triangles are congruent if they have :
exactly the same three sides and
exactly the same three angles.
Tips Area :
If two sides and the included angle of one triangle are equal to the corresponding sides and angle of another triangle, the triangles are congruent too :)
If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent too ;)
If two angles and the non-included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent too ^^
Hope that help :)

Tell the slope and y-intercept of the graph of this linear equation
-3x + 2y = 8
(the slope is a fraction)
Answer:
The slope is 3/2 and the y intercept is 4
Step-by-step explanation:
We want to write in the form
y = mx+b where m is the slope and b is the y intercept
-3x+2y = 8
Add 3x to each side
-3x+3x+2y = 3x+8
2y = 3x+8
Divide each side by 2
2y/2 = 3x/2 + 8/2
y = 3/2x +4
The slope is 3/2 and the y intercept is 4
Which of the following equations is of a parabola with a vertex at (3, 0)?
Oy=x^2+3
o y=x^2-3
Oy= (x+3)^ 2
y=(x-3)^ 2
Answer:
D. y = (x - 3)²
Step-by-step explanation:
The parabola formula in vertex form is:
y = a(x - h)² + k
where the vertex is located at (h, k). Replacing with vertex (3, 0) we get:
y = a(x - 3)² + 0
y = a(x - 3)²
In all possible options the leading coefficient a is equal to one. Therefore:
y = (x - 3)²
Let M(x)=4x2−3x and N(x)=−5x3−6x2−3. Find M(x)−N(x)
Answer:
5x³+10x²-3x+3
Step-by-step explanation:
(4x²-3x) - (-5x³-6x²-3)
5x³+10x²-3x+3
If equations M(x)=[tex]4x^{2} -3x[/tex] and N(x)=[tex]-5x^{3}-6x^{2} -3[/tex] then M(x)-N(x)=[tex]5x^{3} +10x^{2} -3x+3[/tex].
What is equation?An equation is a relationship between two or more variables expressed in equal to form. It is often equated to find the values of variables. The form of an equation is ax+by=c.
How solve equations?We have been given M(x)=[tex]4x^{2} -3x[/tex] and N(x)=[tex]-5x^{3}-6x^{2} -3[/tex] and we have to find the difference between M(x) and N(x) and to solve them we have to open the brackets and add the coefficients of variable.
M(x)-N(x)=[tex]4x^{2} -3x-(-5x^{3}-6x^{2} -3)[/tex]
First we have to open the brackets.
=[tex]4x^{2} -3x+5x^{3}+6x^{2} +3[/tex]
Now we have to add the coefficients of same variable having same powers.
[tex]=5x^{3}+10x^{2} -3x+3[/tex]
Hence if M(x)=[tex]4x^{2} -3x[/tex] , N(x)=[tex]-5x^{3}-6x^{2} -3[/tex] then difference between {M(x)-N(x)} =[tex]5x^{3}+10x^{2} -3x+3[/tex].

1. Solve for w in the equation W/5 = 25
A.W = 5
B.W = 125
C. W = 30
D.W = 20
Answer: w = 125
Explanation: Since w is being divided by 5, to solve for w,
multiply both sides of the equation by 5.
On the left side, the 5's will cancel
and on the right side, 25(5) is 125.
So w = 125.
Please do not do this problem in your head.

What is the x-coordinate of the solution to the following system of equations? x − 2y = 2 3x + y = 6 x = −2 x = 0 x = 2 x = 3
Answer:
Answer C. x = 2
Step-by-step explanation:
Given:
x − 2y = 2
3 * ( x ) + y = 6
You need to group the x-coordinates of the system of equations.
Rewrite x − 2y = 2 , in such a way that it starts with x =...
x = 2y + 2
Substitute x = 2y + 2 in 3 * ( x ) + y = 6, which gives:
3 * ( 2y + 2 ) + y = 6
6y + 6 + y = 6
7y = 0
y = 0
Substitute y = 0 in x = 2(y) + 2 gives x = 2*0 + 2
So x = 2, which is answer C.
x - 6x + 2x - 2x
x - 6x + 0
-5x
The x-coordinate of the solution to the following system of equations x − 2y = 2 and 3x + y = 6 is x = 2. Option c is correct.
system of equations is given as,
x − 2y = 2 - - - - (1)
3x + y = 6 - -- - - -(2)
x coordinate of the solution to the following system of equations to be determined.
the equation is the relationship between variables and is represented as a polynomial equation.
x − 2y = 2 - - - - (1)
3x + y = 6 - -- - - -(2)
From equation 1
x = 2y +2
put x in equation 2
3 (2y + 2) + y = 6
6y + 6 + y = 6
7y = 0
y = 0
Put y = 0 in x = 2y + 2
x = 2(0) + 2
x = 2
Thus, The x-coordinate of the solution to the following system of equations x − 2y = 2 and 3x + y = 6 is x = 2.

A 13 ft ladder is resting on a wall. The angle the ladder makes with the floor is 45 degrees. How high off the ground is the top of the ladder?
Use the function y=13cos(theta) to find the answer
Answer: 9.19 ft
Step-by-step explanation:
Hi, since the situation forms a right triangle (see attachment) we have to apply the next trigonometric function.
Sin α = opposite side / hypotenuse
Where α is the angle of elevation of the ladder to the ground, the hypotenuse is the longest side of the triangle (in this case is the length of the ladder), and the opposite side (x) is the height of the top of the ladder above the ground.
Replacing with the values given:
Sin 45 = x/ 13
Solving for x
sin45 (13) =x
x= 9.19 ft

what is the slant height for given pyramid to the nearest to the whole unit?
A 7 cm
B 5 cm
C 9 cm
D 8 cm
Answer:
B 5 cm
Step-by-step explanation:
The bottom leg of the shaded triangle is 1/2 of the length of the side, so is 3 cm. The vertical leg of the shaded triangle is the height of the pyramid, given as 4 cm.
The slant height is the hypotenuse of the shaded triangle, so can be found from your knowledge of the 3-4-5 triangle, or from the Pythagorean theorem.
If s is the slant height, then ...
s^2 = 3^2 + 4^2 = 9 +16 = 25
s = √25 = 5
The slant height is 5 cm.

Use the data set to answer the question. {22,26,28,35,45,63,91} What is the mean absolute deviation (MAD) of the data set? Enter your answer as a number rounded to the nearest tenth, like this: 42.5
Answer:
[tex]M.A.D = 18.9[/tex]
Step-by-step explanation:
Given: 22,26,28,35,45,63,91
Required: Mean Absolute Deviation
The first step is to solve for the mean of the given data
[tex]Mean = \frac{\sum x}{n}[/tex]
where x->22,26,28,35,45,63,91 and n = 7
[tex]Mean = \frac{22+26+28+35+45+63+91}{7}\\Mean = \frac{310}{7}\\Mean = 44.29[/tex]
Then; subtract the calculated mean from each data
[tex]22 - 44.29 = -22.29\\26 - 44.29 = -18.29\\28 - 44.29 = -16.29\\35 - 44.29 = -9.29\\45 - 44.29 = 0.71\\63 - 44.29 = 18.71\\91 - 44.29 = 46.71[/tex]
Get Absolute Values of the above results
[tex]|-22.29| = 22.29\\|-18.29| = 18.29 \\|-16.29| = 16.29\\|-9.29| = 9.29\\|0.71| = 0.71\\|18.71| = 18.71\\|46.71|= 46.71[/tex]
Calculate the mean of the above result to get the M.A.D
[tex]Mean = \frac{\sum x}{n}[/tex]
[tex]M.A.D = \frac{22.29+18.29+16.29+9.29+0.71+18.71+46.71}{7}\\M.A.D = \frac{132.29}{7}\\M.A.D = 18.8985714286\\M.A.D = 18.9[/tex]
