Is linear equations algebra or pre-algebra??? And is "Collage and career ready math" higher than regular 8th grade math????
Zina [86]
I’m going to say pre-algebra because that’s when I learned it in my school system but you may also learn it in algebra as well, College ready math can start in 8th grade math but I would think it would be in highschool.

How much is a 20% tip
GenaCL600 [577]
That would depend on the price u r originally paying because ur tip is a percentage of the original price.

Lets say u went out to eat and ur meal costs u $ 40. U plan on leaving a 20% tip. So ur tip would be 20% of 40....0.20 * 40 = 8...so a 20% tip on ur meal would be $ 8.

but if ur meal cost $ 25....and u left a 20% tip....20% of 25 = 0.20 * 25 = 5...so if ur meal was $ 25 and u left a 20% tip, u would be tipping $ 5

If ​P(x​) = x^2 + X + 2 and ​Q(x) = 3x^3 - 2​, find ​P(6​).
I am Lyosha [343]

Answer:

The answer is P(6) is 44.

Step-by-step explanation:

Given:

If ​P(x​) = x^2 + X + 2 and ​Q(x) = 3x^3 - 2​.

Now, to find P(6).

P(x)=x^2+X+2

P(6)=6^2+6+2

P(6)=36+6+2\\P(6)=44.

Therefore, the answer is P(6) is 44.

What is the length of a radius of the circle represented by the equation
Arlecino [84]

Answer:

A) 2 units

Step-by-step explanation:

Given;

x² + y² - 4x - 4y + 4 = 0

Consider general circle equation;

(x - h)² + (y - k)² = r²

where;

(h , k ) is the center of the circle

r is the radius of the circle

x² + y² - 4x - 4y + 4 = 0

subtract 4 from both sides of the equation

x² + y² - 4x - 4y  =  - 4

square half of coefficient of x and y, and add them to both sides of the equation

x² +  - 4x + (-2)² +  y² - 4y + (-2)² = - 4 +  (-2)² +  (-2)²

factorize x and y

(x - 2)² + (y - 2)² = - 4 + 4 + 4

(x - 2)² + (y - 2)² = 4

(x - 2)² + (y - 2)² = 2²

Compare this final equation to general equation of a circle

(x - 2)² + (y - 2)² = 2²  

(x - h)² + (y - k)² = r²

r = 2

Thus, the length of a radius of the circle is 2 units
