3. Connie bought several types of candy for Halloween: Milky Ways, Tootsie Rolls,
devlian [24]

Answer:

Tootsie Rolls = 13

Step-by-step explanation:

Given:

Milky Ways and Tootsie Rolls together were 15 more than the number of Reese's Cups.

There were 4 fewer Reese's Cups than Hershey Bars.

There were 12 Milky Ways and 14 Hershey Bars.

Solution

Milky Ways and Tootsie Rolls = Reese's Cups + 15

There were 4 fewer Reese's Cups than Hershey Bars.

Hershey Bars = 14

Then,

Reese's Cups = 14 - 4

= 10

Milky ways = 12

Hershey bars = 14

Reese's Cups = 10

Milky ways = 12

Milky Ways + Tootsie Rolls = Reese's Cups + 15

12 + Tootsie Rolls = 10 + 15

12 + Tootsie Rolls = 25

Subtract 12 from both sides

Tootsie Rolls = 25 - 12

= 13

Tootsie Rolls = 13

Perform the indicated operations. Write the answer in standard form, a+bi.<br> (5 + 6i)(5 - 6i)
lubasha [3.4K]

\boxed{\underline{\bf \: ANSWER}}

\sf \: ( 5 + 6 i ) ( 5 - 6 i )

Multiply complex numbers 5+6i and 5-6i in the same way as you multiply binomials.

\dashrightarrow \sf 5\times 5+5\times \left(-6i\right)+6i\times 5+6\left(-6\right)i^{2}

By definition, i² is -1.

\dashrightarrow \sf 5\times 5+5\times \left(-6i\right)+6i\times 5+6\left(-6\right)\left(-1\right)

Do the multiplications.

\dashrightarrow \sf \: 25-30i+30i+36

Now cancel -30i & +30i

\dashrightarrow \sf \: 25 \:  \bcancel{- 30i}  \:  +  \: \bcancel{30i}+36

Now the equation becomes

\dashrightarrow \sf \: 25 \:  + 36 \\ \dashrightarrow  \boxed{\bf \: 61}

________

Hope it helps.

What is the Domain and Range of the function f(x)<img src="https://tex.z-dn.net/?f=%5Csqrt%7Bx-7%7D%20%2B9" id="TexFormula1" tit
omeli [17]

For the given function, the domain is D : { x ≥ 7} and the range is R: { y ≥ 9}

<h3>How to get the domain and range?</h3>

Here we have a square root, remember that the argument of the square root must be equal or larger than zero, so the domain is such that:

x - 7 ≥ 0.

Solving for x we get:

x ≥ 0 + 7

Then the domain is:

x ≥ 7

To get the range, we evaluate in the minimum of the domain:

f(7) = √(7 - 7) + 9 = 9

Then the range is the set of all values larger than 9, because the function is increasing.

So the range is R: y ≥ 9.

If you want to learn more about domain and range:
