Lets use the letter C to represent cats and D to represent dogs.
A) 2.35c + 5.50d = 89.50
For B, they give you numbers to plug into your equation.
c = 8
d= 14
B) 2.35(8) + 5.50(14) = 89.50
18.80 + 77.00 = 95.80
So what Pat said is incorrect because that would mean they spent more than 89.50.
Hope this helps! :)
Answer:
-1/4
Step-by-step explanation:
For this equation, first divide both sides by 1.2, to get x+4y=15. Then, subtract x from both sides. Now, with 4y=-x+15, divide by 4. You should get y=-1/4x+15/4 (15/4=3 3/4 or 3.75). The formula y=kx=b, where k is slope, means the slope is -1/4.
Answer:
The recursive formula to model Kendyl's progress is:
Fourth option: an=an-1 + 2, a1=8
Step-by-step explanation:
She currently has the first eight bars memorized: The first value is 8:
a1=8
She plans to memorize two more bars everyday until she has the whole piece memorized:
The number of bars memorized is two more than the last day:
an=an-1 + 2
Then, the recursive formula is:
an=an-1 + 2, a1=8
