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
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.

Please help me .............
Answer:
The first one.
Step-by-step explanation:
For something to be considered to be a graph, every x value must have 1 y value. It does not matter if y values are the same, but you MUST make sure there is ONLY ONE of each value. So for example the second one wouldn't be a function because -5 appears twice for the x values, but with different y values. This would mean when graphed, it would fail the vertical line test (if you put a vertical line anywhere on the graph you will only get one point).
Answer:
The first one
Step-by-step explanation:
because it is the only one that actually applies to the function
A piggy bank contains only nickels, dimes, and quarters. There is a total of 105 coins and the total value of those coins is $10.75. Find a general solution of the number of each coin. List three possible specific solutions.
1.Segments AB, EF, and CD intersect at point C, and angle ACD is a right angle. Find the value of g. Do NOT include degrees.
2.Find the area of the unshaded part of the figure
3. In the figure, angles c and e are vertical angles. Angles a and c are complementary angles. The measure of angle d is 124 degrees and the measure of angle c is 56 degrees.
Answer:
See below;
Step-by-step explanation:
1 . Consider the step below;
[tex]m< DCA = 90 degrees - Given ,\\m< ACB = 180 degrees - Straight < ,\\\\m< DCA + m< DCB = 180,\\m< DCB = 90 degrees,\\\\By Parts Whole Postulate - m< DCB = m< DCE + m< ECB,\\m< DCB = m< DCE + m< ECB,\\90 = 53 + g,\\Conclusion ; ( g = 37 degrees )[/tex]
Thus, Solution ; g = 37 degrees
2 . Knowing that these circle are " circumscribed " in this rectangle so that they are perfectly aligned, considering the length of this rectangle to be 20 inches, let us determine the radius;
[tex]Diameter Of 1 Circle - ( 20 inches ) / 4 = 5 inches,\\Radius of 1 Circle = ( 5 inches ) / 2 = 2.5 inches,\\\\Area of 1 Circle = \pi r^2 = \pi * ( 2.5 )^2 = 6.25\pi,\\Area of 4 Circles = 6.25\pi * 4 = 25\pi,\\Area of 4 Circles = Area of Shaded Region,\\\\Conclusion ; Area of Shaded Region = 25\pi[/tex]
Thus, Solution ; 25π
3. Let us first consider the given, then solve for the value of a, b, e;
[tex]Angles c + e - Vertical Angles,\\Angles a + c - Complementary,\\( a + c ) = 90,\\Angle c = 56 degrees,\\a + 56 = 90,\\Conclusion ; a = 34 degrees,\\\\[/tex]
[tex]m< e = m< c,\\Conclusion ; e = 56 degrees[/tex]
[tex]m< e + m< a + m< b = 180 - Straight Line,\\56 + 34 + m< b = 180,\\m< b = 180 - 56 - 34,\\Conclusion ; b = 90 degrees[/tex]
Solution; a = 34°, b = 90°, e = 56°
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%
Simplify by dividing 3/5 ÷ (-9/4)
Answer:
4/15
Step-by-step explanation:
You would have to multiply the fractions, but first reciprocate the dividend.
3/5 * 4/9
Multiply
3 * 4 = 12
5 * 9 = 45
12/45
Simplify using LCM, or the factor that applies to both sides which in this case is 3
12/3 = 4
45/3 = 15
The answer is 4/15
Answer:
4/-15
Step-by-step explanation:
[tex]\frac{3}{5}[/tex] ÷ [tex]\frac{-9}{4}[/tex]
Invert the second fraction and multiply
[tex]\frac{3}{5}[/tex] ×[tex]\frac{4}{-9}[/tex]
= [tex]\frac{12}{-45}[/tex]
Simplify:

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

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

What is the maximum value?
Answer:
the maximum value is 3
Step-by-step explanation:
The maximum value of the function y = -2+5sin(pi/12(x-2)) is determined by taking the first derivative of the function. The first derivative is equal ( 5 pi/ 12 )* sin ((pi/12) (x-2)) = 0. x is equal to 4472 through the calculator. Substituting to the original equation, the maximum value is 3.
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]

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 ^^

Answer: OA) 5:3
Step-by-step explanation:
5:3
5 to 3. Or 5/3. Are the 3 ways that you.can write a ratio.
Answer:
OA, OB, OD
Step-by-step explanation:
It does depend on which side each number is on. If you are comparing the stawberries to whipped cream it would be 5:3 (OA).
But if you were to compare whipped cream to stawberries it would be 3:5 (OB) or 3/5 (OD)

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

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.
Show the work that it takes to get w by itself.
Solve the equation using square roots.
