Answer:
3i + 10
Step-by-step explanation:
4i + 3 - i + 7
= (4i - i) + (3 + 7)
= 3i + 10
6x=shelia total deposit
<span>
<span>
</span>
5y=sherri total
</span><span>
<span>
</span>
sheri is 10 more than shelia so
</span><span>
<span>
</span>
y=10+x
</span><span>
<span>
</span>
and also they deposed same amount total
</span><span>
<span>
</span>
6x=5y
</span><span>
<span>
</span>
6x=5(10+x)
</span><span>
<span>
</span>
6x=50+5x
</span><span>
<span>
</span>
minus 5x both sides
</span><span>
<span>
</span>
x=50
</span><span>
<span>
</span>
y=10+x
</span><span>
<span>
</span>
y=10+50
</span><span>
<span>
</span>
y=60
</span>
<span>
</span>
shelia deposits $50 each and sherri deposits $60 each
50*6=300
60*5=300
300=300
ok answer to questions
Write an equation. Let x represent the amount of one of Sheila’s deposits. and y is the other one, 5x=6y, y=10+x
⦁ Solve the equation. Show your work. see above
⦁ Check your solution. Show your work.
⦁ State the solution in complete sentences. Shelia deposited $50 each time, Sherri deposited $60 each time
Sine is an odd function, and cosine is an even function. You may not have come across these adjectives “odd” and “even” when applied to functions, but it's important to know them. A function f is said to be an odd function if for any number x, f(–x) = –f(x). A function f is said to be an even function if for any number x, f(–x) = f(x). Most functions are neither odd nor even functions, but some of the most important functions are one or the other.
The answer is false.
Answer:
165
Step-by-step explanation:
