Answer:

Step-by-step explanation:

Given

5 - $\sqrt{c+5}$ = 1 ( subtract 5 from both sides )

- $\sqrt{c+5}$ = - 4 ( multiply both sides by - 1 )

$\sqrt{c+5}$ = 4 ( square both sides )

c + 5 = 4² = 16 ( subtract 5 from both sides )

c = 11

2. If ¡2x+3 = i, where i = V-1, then which of the

Alexus [3.1K]

I assume you mean the equation

$i^{2x+3} = i$

Since i = √(-1), we have i⁴ = 1 and so i⁵ = i. Then 2x + 3 must be some multiple of 5.

Now just check for which of the given choices that this holds:

x = 16 ⇒ 2x + 3 = 35 (yes)

x = 11 ⇒ 2x + 3 = 25 (yes)

x = 10 ⇒ 2x + 3 = 23 (no)

x = 14 ⇒ 2x + 3 = 31 (no)

How do I do Slope Intercept Form Step to Step? PLEASE HELP!

Arlecino [84]

So if an equation was f(x)=x+4

you would automatically change f(x) into y

so it would y-y=x(x-x)

so you plug in the x and 4 which is the first y and x

y-4=x(x-x)

you switch the numbers around

so your final answer would be x-4

1. f (x) = 5x + 10. If x = 10, then what is the value of f(x)?

UkoKoshka [18]

Answer:

B: 60

Step-by-step explanation:

f(x)= 5x+10, if x=10

f(10)=5(10)+10

5(10)+10=60

f(10)=60
