If x + 3y = 7 and x - 3y =7 , then find y
Please help me
Answer:
[tex]x + 3y = 7 , x - 3y = 7 : y = , x = 7[/tex]
Step-by-step explanation:
[tex]\left[\begin{array}{ccc}x + 3y = 7\\x - 3y = 7\end{array}\right][/tex]
Isolate [tex]x[/tex] for [tex]x + 3y = 7 : x = 7 - 3y[/tex]:
Substitute [tex]x = 7 - 3y[/tex]:
[tex]\begin{bmatrix}7-3y-3y=7\end{bmatrix}[/tex]
Isolate [tex]y[/tex] for [tex]7 - 3y - 3y = 7 : y = 0[/tex]:
For [tex]x[/tex] [tex]=7-3y[/tex]
Substitute [tex]y = 0[/tex]
[tex]x=7-3 * 0[/tex]
[tex]7 - 3 * 0 = 7[/tex]
[tex]x = 7[/tex]
The solution to the system of equations are:

Express -2(x - y) -10 = 0 in standard form.
Answer:
2x - 2y = - 10
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Given
- 2(x - y) - 10 = 0 ← distribute parenthesis on left side
- 2x + 2y - 10 = 0 ( add 10 to both sides )
- 2x + 2y = 10 ( multiply through by - 1 )
2x - 2y = - 10 ← in standard form
n + 2 = -14 – n please help ik the ansewer i need the woorkkk
Answer:
n = -6
Step-by-step explanation:
n + 2 = -14 - n
2n + 2 = -14
2n = -12
n = -6
Answer:
Step-by-step explanation:
So in the case of "n" being any given variable, (basically saying it could be replaced by x, or any other variable) the answer would be,
n = -6
Work:
n + 2 = -14 - n
Cancel out the negative n on the right side by adding one n to both sides.
n + n = 2n
2n + 2 = -14
Get rid of the 2 on the left side, isolating the variable (2n)
2 + 14 = -12
2n = -12 is the final equation, and the last step is to divide both sides by 2, again isolating the variable.
Final answer is,
n = -6.

-x = 2 - 3x +3
Combine like terms
-x = -3x+5
Add 3x to each side

Given Event A, Event B, and Event C. Event A and Event B are mutually exclusive. Event A and Event C are not mutually exclusive.
P(A) = 0.15
P(B) = 0.35
P(C) = 0.55
What is the probability of the complement of Event B?
0.85
0.35
0.65
0.45
Answer:
0.35
Step-by-step explanation:
The probability of the complement of Event B is equal to 0.65. so option C is correct.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
Given;
Event A and Event B are mutually exclusive.
We have given data
P(A) = 0.15
P(B) = 0.35
P(C) = 0.55
We need to find the he probability of the complement of Event B.
The formula for the compliment of the event
P( B⁻ ) = 1 - P( B)
Use the given value in the above formula we have,
= 1 - 0.35
= 0.65
The probability of the complement of Event B is equal to 0.65. so option C is correct.

What is the final transformation in the composition of transformations that maps pre-image GHJK to image G'H"J"K"? a translation to the right a reflection across line m a 90° rotation about point G a 180° rotation about point G
Answer:
a reflection across line m answer is b
Step-by-step explanation:
A reflection across lime m is the final transformation of pre-image GHJK to image G'H"J"K". Option B is correct.
The final transformation is to determine that transition states have been shown in the image that describes how pre-image GHJK transformed to image G'H"J"K".
Reflection is defined in an atmosphere as when the beam of light or wave strikes to the plane or curved surface deviates back from the atmosphere.
Steps of Transformation
Pre-image GHJK first rotates anticlockwise by an angle of 90° to G'H'J'K'.
Then G'H'J'K' reflected across the line m to G'H"J"K". It is the final transition state.
Thus, a reflection across lime m is the final transformation of pre-image GHJK to image G'H"J"K".

Complete the following sentence about the rate of change in the tiger population. Round your answer to two decimal places
two decimal places.
The tiger population loses 3/5 of its size every ______ decade.
Answer:
0.33 decades
Step-by-step explanation:
The tiger population loses 3/5 of its size every 0.333 decades.
What is an Exponential Function?An exponential function is what can be represented by the equation
y = aˣ
The number of tigers N(t) has been modeled by the equation
[tex]\rm N(t) = 710 * (\dfrac{8}{125})^t[/tex]
The tiger population loses 3/5th of its size in how much decade has to be found.
if it loses 3/5, the remaining will be 3/5 of the size so,
[tex]\rm \dfrac{2}{5} * 710 = 710 * (\dfrac{8}{125})^t\\\\\\dfrac{2}{5} = (\dfrac{8}{125})^t\\[/tex]
Taking log on both the sides
ln 2 - ln 5 = t( ln 8-ln 125)
t= 0.333
Therefore, the tiger population loses 3/5 of its size every 0.333 decades.
