Answer:
It does show direct variation.
Step-by-step explanation:
Every hour, you receive $8.50. This doesn't change throughout the entire table. On a graph, this would look like a line going through the origin, with points at (1, 8.5). (2, 17), (3, 25.5), and so on.
Answer:
(9-10x)(9+10x) (I think this is the answer but I'm not one hundred percent sure)
Step-by-step explanation:
First, you can recognize that both numbers (-100x^2 and 81) are a difference of squares, in which means that they both can be square routed. Then, plug in the square routes of the numbers into (9-10x)(9+10x). 9 is the square route of 81 and 10 is the square route of 100. Make sure that when you put the numbers in the parenthesis that there is one negative and positive number since a negative multiplied by a positive makes a negative, hence making 100 negative. I hope that helped.
Answer:
5/16
Step-by-step explanation:
It's a little easier when you write the problem like this:
3 5
----- · -----
8 6
Now reduce that 3/6 to 1/2:
1 5
----- · ----- = 5/16
8 2
Answer:
1. 
2. m
3. 6w
4. 39x + 78
5. 75x - 153
Step-by-step explanation:
1. The product of −2c+14 and the multiplicative inverse of −12 is
Use distributive property:
2. Solve 10+(m−10)
Open the brackets remembering that the sign before brackets is "+":
Combine the like terms usin commutative property:
3. Solve 6w+3−3
Combine the like terms:
4. Write the expression in standard form 13(3x+6).
Use distributive property:
5. Write the expression in standard form 15(5x−10)−3.
Use distributive property:
