Answer:
f(-7) = 34
Step-by-step explanation:
If f(x) = -5x - 1, then . . .
f(x) = -5x - 1
f(-7) = -5(-7) - 1
= 35 - 1
= 34
. . . because in f(-7), the (-7) is the x-value you're supposed to use to find the value of the function.
Answer:
Step-by-step explanation:
- <em>Assuming copper sulfate has same density as water</em>
<u>Chemical to water ratio as per given is:</u>
- 250 kg : 1000 liter = 1 kg : 4 liter
Lab solution is 350 ml
<u>Converting to same ratio as above:</u>
350/(1 + 4) = 70 ml
- 70 ml : 280 ml = 70 g : 180 ml = 0.07 kg : 180 ml
Answer is 0.07 kg
ANSWER
My Answer is in the photo above
A = 0.366666 ... = 0.3(6)
10a = 3.(6)
100 a = 36.(6)
100a - 10a = 36.(6) - 3.(6)
90a = 33
a=33/90=11/30
oh wait lol i didnt notice it was from 2017
