You need to graph c<=20.
to graph it, you would have a closed dot on 20, going to the left and stopping at 0.
Answer:
x^2 + 8x + 15
Step-by-step explanation:
( x + 3 ) ( x + 5 )
1. distribute
( x + 3 ) ( x + 5 )
x^2 + 3x + 5x + 15
2. simplify
x^2 + 8x + 15
Answer:
use the equations that are given along with a little imagination.
Step-by-step explanation:
when turning equations into word problems you must use equation that's given.
For example:
•x -3=10
Now lead them into the problem:
-Lyndsey bought 3 less shirts than Riley. Solve for x, How many shirts does Riley have more than Lyndsey if together they have 10 shirts?
A) f(x+1) = 6x^2 + 8x + 6
1) substitute the value of x as (x+1)
2) 2(3(x+1)^2 -2(x+1) +2)
3) 6(x^2 + 2x + 1)
4) 6x^2 + 8x + 6
B) f(3) = 46
1) simplify the expression first
2) 6x^2 -4x + 4
3) Now just substitute 3: 6(3)^2 -4(3) + 4
4) 6•9 - 12 + 4 = 46
I hope this helps :)
1 30 30
-- x ---- = ---- ---> 30/5 = 6
5 1 5
30 is a full number but it can turn into a fraction. The whole number (30) will be the numerator (the top number) and 1 is basically "the quantitative number" aka the denominator (the bottom number).
The final result of this problem is 30 over 5. Which you can divide. Always divide the numerator to the denominator to get your answer (for this kind of problem).
