Theo started to solve the quadratic equation (x 2)2 – 9 = –5. he added 9 to both sides and the resulting equation was (x 2)2 = 4. next, he took the square root of each side. which was the resulting equation of that step? x 2 = ±4 x 2 = ±2 x 2 = ±8 x 2 = ±16
Answers
The resulting equation of that step is the square root of (x + 2)² is (x + 2).
What is the square root function?A square root function is defined as a one-to-one function that takes a positive number as an input and returns the square root of the given input number.
From there, it was pretty easy for Theo to find the solutions
to the original equation.
If (x + 2) = +2 , then x = 0 .
If (x + 2) = -2 , then x = -4
Hence, the resulting equation of that step is the square root of (x + 2)² is (x + 2).

A trail around a river is 3 1/4 miles long. What is the length, in feet, of the trail?
Answers
Answer: 17160 feet
Step-by-step explanation:
We know that 5280 feet = 1 mile
So all we have to do is multiply 3 1/4 by 5280
Let's split the 3 and 1/4 up to make the multiplication easier
3×5280=15840
[tex]\frac{1}{4}[/tex]×5280=[tex]\frac{5280}{4} =1320[/tex]
Now add them together

Mitch tried to solve an equation step by step.
7.7 = W - 2
7.7 – 2 = W - 2 + 2 Step 1
5.7 = w
Answers
Answer:
Mitch did not make a mistake
Step-by-step explanation:
The -2 and 2 on the right side cancel out and so you are left with 7.7-2=w. Combine like terms and your left with 5.7=w
When simplifying this I would notice that one side is subtracting 2 (a rational number) and that the other also has a rational number.
To simplify this, you have to get rid of the -2 by canceling it out. You can do this by adding 2 on both sides (you have to add 2 to both sides to make sure both sides of the equal sign are equal).
So instead of subtracting 2 on one side and subtracting 2 on the other, you are supposed to add 2 to both sides.
They solved the second step correctly

Answer: just graph it using the x and y coordinate points
Step-by-step explanation:
Answer:
(-4, -2)
Step-by-step explanation:
Rewrite the equations to make y the subject, so that it's easier to calculate the points on each line:
Equation 1
x - y = -2
⇒ x + 2 = y
⇒ y = x + 2
Equation 2
2x - 3y = -2
⇒ 2x + 2 = 3y
⇒ y = (2/3)x + 2/3
Calculate 2 points on each line:
Equation 1 (blue line on attached graph)
Substitute x = 0 and x = -2 into Equation 1 to create 2 points:
x = 0: y = 0 + 2 ⇒ (0, 2)
x = -2: y = -2 + 2 ⇒ (-2, 0)
Plot the points and draw a line through them.
Equation 2 (red line on attached graph)
Substitute x = 2 and x = -1 into Equation 1 to create 2 points:
x = 2: y = (2/3)(2) + 2/3 ⇒ (2, 2)
x = -1: y = (2/3)(-1) + 2/3 ⇒ (-1, 0)
Plot the points and draw a line through them.
Solution
The solution is the point where the two lines intersect.
Therefore, the point of intersection is (-4, -2)

Answer:
the median is 15, there is no mode.
Step-by-step explanation:
to find the median- put the numbers in order from least to greatest (13,14,14,16,16,19) use a sheet of paper and cross off each number on the ends until you get to the middle. Once you have reached the middle you should have the two numbers 14, 16. Take 14 and 16, add them together and you will get 30. Divide 30 by 2 because there is two numbers for the median. You should end with 15 as your median.
to find the mode- find the number that occurs the most in the set of numbers, in this case all numbers occur the same amount of times, so therefor there is no mode.

Step-by-step explanation:
Method 1
Apply Difference of Two Squares Formula: [tex]a^2-b^2=(a+b)(a-b)[/tex]
Given [tex]x^2-16=0[/tex]
Rewrite 16 as 4²
Therefore, [tex]a^2=x^2[/tex] and [tex]b^2=4^2[/tex]
[tex]\implies a = \sqrt{x^2}=x[/tex]
[tex]\implies b=\sqrt{4^2} =4[/tex]
[tex]\implies x^2-16^2=(x+4)(x-4)[/tex]
[tex]\implies (x+4)(x-4)=0[/tex]
[tex]\implies (x+4)=0 \implies x=-4[/tex]
[tex]\implies (x-4)=0 \implies x=4[/tex]
Method 2
Given equation:
[tex]x^2-16=0[/tex]
Add 16 to both sides:
[tex]\implies x^2-16+16=0 + 16[/tex]
[tex]\implies x^2=16[/tex]
Square root both sides:
[tex]\implies \sqrt{x^2}=\sqrt{16}[/tex]
[tex]\implies x=\pm4[/tex]
Therefore, x = -4, x = 4
