3) A linear equation to represent this would be 205 = 10x + b
x is days passed, which is 10, and b is the original amount.
10 times 10 is 100, so we now have 205 = 100 + b
Subtract 100 from both sides to get 105 = b, which is the starting amount.
The rate of change is 10, however many cans brought per day.
4) So it appears that for every 5 minutes she frosts 4 cupcakes, which means the rate of change is 4/5 using rise over run.
Subtract 4 from 28 to get the starting amount 5 minutes earlier.
The starting amount of frosted cupcakes is 24.
5) Every 3 months he gets 9 more CDS. So, every month he gets 3 new CDs.
That means the slope is 3.
Subtract 9 from 18 to get the starting amount.
The starting amount of CDs is 9.
Hope this helps!
Answer:
14. 36
15. 12.5
16. 2.5
17. -34,359,738,368
Step-by-step explanation:
14.
F(2) = 6^2
= 36
15.
G(-2) = 2*.4^-2
= 2*1/.16
= 2/.16 or 1/.08 or 12.5
16.
y = 20*.5^3
= 20*.125
= 2.5
17.
H(w) = -0.5*4^18
= -34,359,738,368
It would be C.
In the second triangle if you add the angles 58+33 to angle C 88, you get 179, not 180. So the triangle dont share the same angles meaning they arent congruent.
Hope this helps.
Brainliest would help me as well.
I belive the answer to your question would be -7a^2b^3
