Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define systems
y = 5x - 3
3x - 2y = 27
Step 2: Rewrite systems
Define: 3x - 2y = 27Add 2y on both sides: 3x = 2y + 27Divide 3 on both sides: x = 2/3y + 9Step 3: Redefine
y = 5x - 3
x = 2/3y + 9
Step 4: Solve for y
Substitute in x: y = 5(2/3y + 9) - 3Distribute 5: y = 10/3y + 45 - 3Combine like terms: y = 10/3y + 42Subtract 10/3y on both sides: -7/3y = 42Divide -7/3 on both sides: y = -18A 15 W electric shaver is used for 3 minutes. How much energy does it use?

What's A Angle Bisector And A Bisector?
Answer:
Bisection
In geometry, bisection is the division of something into two equal or congruent parts, usually by a line, which is then called a bisector. The most often considered types of bisectors are the segment bisector and the angle bisector.
Angle Bisector
The (interior) bisector of an angle, also called the internal angle bisector (Kimberling 1998, pp. 11-12), is the line or line segment that divides the angle into two equal parts. The angle bisectors meet at the incenter.

6y+4−3y−7=3(y−1) How many solutions are for this?
Answer:
Infinite amount of solutions.
General Formulas and Concepts:
Order of Operations: BPEMDASRegular + Equality PropertiesStep-by-step explanation:
Step 1: Define equation
6y + 4 - 3y - 7 = 3(y - 1)
Step 2: Solve for y
Combine like terms: 3y - 3 = 3(y - 1)Distribute 3: 3y - 3 = 3y - 3Subtract 3y on both sides: -3 = -3Here we see that there will be infinite amount of solutions. We can plug in any number y and it will render the equation true.

Solve by finding square roots
4 (x-1)^2=96
Answer:
2√6 + 1
Step-by-step explanation:
Given expression:
4(x-1)² = 96
Solving by square root;
Square root both sides;
[tex]\sqrt{4(x-1)^{2} }[/tex] = √96
√4(x-1)² = √6x16
√4(x-1)² = 4√6
2(x-1) = 4√6
Divide both sides by 2;
x-1 = 2√6
Add 1 to both sides;
x = 2√6 + 1
The length of Joe's arm is 28 inches. The length of his lower arm is 21 inches. What percent of Joe's arm is his lower arm?
Answer:
75%
Step-by-step explanation:
You take the length of the lower arm, 21, and divide it by the total length, 28. Your equation should be 21/28 = 3/4 =.75. 0.75 is equal to 75%
Answer:
75%
Step-by-step explanation:
You take the length of the lower arm, 21, and divide it by the total length, 28. Your equation should be 21/28 = 3/4 =.75. 0.75 is equal to 75%

What is the square of the complex number (i - 2)?
Select one:
O A. -4- 4i
O B. -4
O C. 3 – 4i
O D. 4- 4i
O E. 4+4i
Answer:
Step-by-step explanation:
Square of (i-2)=(i-2)^2
=i^2-4i+4
Since i^2=-1
So
=i^2-4i+4
=-1-4i+4
=3-4i
Answer is 3-4i( option c)

A parent is using a garden hose to fill up a small inflatable pool for her young child. The pool has a capacity of 90 gallons. She turns the water off after 5 minutes, but leaves the hose in the pool for another 3 minutes before putting it away.
In this situation, the relationship between the gallons of water in the pool and the 8 minutes since the parent started filling the pool can be seen as a function.
In that function, which variable is independent? Which one is dependent?
Type your response in the space below.
Answer:
Independent variable = the time. Dependent variable = amount of water per minute
Step-by-step explanation;
The total amount of water depends on how long the hose is left on.
The relationship between the gallons of water in the pool and the 8 minutes since the parent started filling the pool can be seen as a function is ''the total amount of water depends on how long the hose is left on''.
Time is the independent variable.
The amount of water per minute is the dependent variable.
Given
A parent is using a garden hose to fill up a small inflatable pool for her young child.
The pool has a capacity of 90 gallons.
She turns the water off after 5 minutes but leaves the hose in the pool for another 3 minutes before putting it away.
What is the independent variable?Independent variables are the variables that the experimenter changes to test their dependent variable.
What is the dependent variable?A change in the independent variable directly causes a change in the dependent variable.
1. The relationship between the gallons of water in the pool and the 8 minutes since the parent started filling the pool can be seen as a function is ''the total amount of water depends on how long the hose is left on''.
2. Time is the independent variable.
3. Amount of water per minute is the dependent variable.

Answer:
[tex]\boxed {129\textdegree}[/tex]
Step-by-step explanation:
Both angles labeled, are actually Supplementary Angles (which two angles that add up to [tex]180\textdegree[/tex]). So, to find the missing measurement of an angle, which is the angle labeled in [tex]x[/tex], you need to take [tex]51\textdegree[/tex] and subtract it from [tex]180\textdegree[/tex] to get the missing angle measurement:

Steph bought a used bicycle, restored it, and then marked it up 1/4 of the price she paid. Later she sold it for the marked up price $80. How much, in dollars did Steph pay for the bicycle
Price she paid, P = $80 .
She sells the bicycle at 1/4 of the price she paid.
Let, buying price is x.
So, as given in question selling price will be x/4.
Also, selling price is given as $80 .
[tex]\dfrac{x}{4}=80\\\\x = \$320[/tex]
Therefore, Steph pay $320 for the bicycle.
Hence, this is the required solution.
