Equation: M+6/-3=4
What did you do?
Simplify/complete sentence
Answers
Following the order of operations, 6 divided by -3 is -2. So we can replace that with -2 and get:
M+-2=4
Adding a negative is the same thing as subtracting.
M-2=4
Then we can add 2 to both sides to get rid of the 2.
M-2+2=4+2
M = 6

1.Consider the quadratic relation y = x^2 – 6x – 16.
a) Factor this equation using the Trinomial Method (find two numbers that multiply to 'c' and add to 'b'; the factored form has 2 pairs of brackets).
b) Find the x-intercepts (zeroes) of the relation. Remember to let y = 0 then solve for each x separately.
2. Consider the quadratic relation y = 2x^2 + 6x – 80. a) Factor this equation by:
1. Determining the greatest common factor (GCF).
2. Factoring the equation using common factoring.
3. Factor the expression inside the brackets using the Trinomial Method (find two numbers that multiply to 'c' and add to 'b'; the factored form has 2 pairs of brackets).
b) Find the x-intercepts (zeroes) of the relation. Remember to let y = 0 then solve for each x separately.

Answer:
Step-by-step explanation:
1.Consider the quadratic relation y = x^2 – 6x – 16.
a) Factor this equation using the Trinomial Method (find two numbers that multiply to 'c' and add to 'b'; the factored form has 2 pairs of brackets).
[y = x^2 – 6x – 16 : Two numbers when multiplied = -16, but when added = -6, would be: -8 and 2. [-8+2 = -6, and -8*2 = -16] This would lead to (x+2)(x-8) as the two factors.
b) Find the x-intercepts (zeroes) of the relation. Remember to let y = 0 then solve for each x separately.
(x+2)=0; x= -2
(x-8)=0; x = 8
2. Consider the quadratic relation y = 2x^2 + 6x – 80.
a) Factor this equation by:
1. Determining the greatest common factor (GCF).
The GCF is 2: 2*(x^2 + 3x - 40)
2. Factoring the equation using common factoring.
2*(x^2 + 3x - 40): Two numbers that when multiplied = -40, but added = 3, would be 8 and -5. So we can factor:
2*(x + 8)(x - 5)
3. Factor the expression inside the brackets using the Trinomial Method (find two numbers that multiply to 'c' and add to 'b'; the factored form has 2 pairs of brackets).
2*(x + 8)(x - 5)
b) Find the x-intercepts (zeroes) of the relation. Remember to let y = 0 then solve for each x separately.
0 = (x + 8) and 0=(x - 5); x = -8, and x=5

When G(2,-6) is reflected in the line y = -2, the image is located at G |
Answers
Answer:
The point (2, -6) is four below the line y= -2
The reflection will be four below the line y=-2.
Since y=-2 is a horizontal line, the reflection will be vertical,
so (2,-6) will reflect down 6 spaces vertically. -6 + (4*2) = (-6 + 8) = 2 therefore when we establish 4 below the line we just apply * 2 as a double as its across the line each side of the line to find that below the line = 4 = 4*2 and add it to -6
(2,-6) reflected over y=-2 reflects to (2, 2 )

Answer:
x = 120
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles, then
x = 70 + 50 = 120
Answer:
X=120
Step-by-step explanation:
exterior angle of triangle is equal to its two opposite interior angles .
hence, X= 70 + 50

Nick has $50. He just got a job as a construction worker making $10 an hour. He wants to earn enough money to buy himself a new cell phone, valued at $900. If x represents the number of hour he works, write an inequality to represent this situation. What is the minimum number of hours must he work to buy the phone?
Answers
Answer:
900[tex]\geq[/tex]50+10x; At least 85 hours
Step-by-step explanation:
Nick must make at least 900 dollars, so the amount he has + earns must be greater than or equal to 900 in order to walk out of the store with it.
50 is the amount that Nick already has, and add that to 10x, which gives $10 for every x hour.
To solve, subtract 50 from each side.
850[tex]\geq[/tex]10x
Divide by 10 to solve for x:
85[tex]\geq[/tex]x
