If you would like to know which subtraction expression has the difference 1 + 4i, you can calculate this using the following steps:

a. (–2 + 6i) – (1 – 2i) = –2 + 6i – 1 + 2i =  –3 + 8i

b. (–2 + 6i) – (–1 – 2i) = <span>–2 + 6i + 1 + 2i =  </span>–1 + 8i

c. (3 + 5i) – (2 – i) = 3 + 5i – 2 + i = 1 + 6i

d. (3 + 5i) – (2 + i) = 3 + 5i – 2 – i = 1 + 4i

The correct result would be <span>d. (3 + 5i) – (2 + i).</span>

A small art museum charges $5 for an adult ticket and $3 for a student
Shkiper50 [21]

There were 37 student tickets and 52 adult tickets

Step-by-step explanation:

Let x be the number of student tickets and y be the adult tickets

Then

According to given statement that total 89 tickets were sold

x+y=89     Eqn 1

And

$5 for an adult ticket and $3 for student ticket ,and total cost $371

3x+5y=371    Eqn 2

From eqn 1

x=89-y

Putting in eqn 2

3(89-y)+5y=371\\267-3y+5y=371\\267+2y=371

Subtracting 267 from both sides

267+2y-267=371-267\\2y=104

Dividing both sides by 2

\frac{2y}{2}=\frac{104}{2}\\y=52

Putting y=52 in eqn 1

x+52=89\\x=89-52\\x=37

Hence,

There were 37 student tickets and 52 adult tickets

When 50% of a number is added to the number, the result is 135
bonufazy [111]
Let's call the unknown number x.
x+ (50% of x) = 135

x + (0.5x) = 135
1.5x = 135
x = 135/1.5
x = 90

Therefore, the number is 90

The directex of Y=1/8x^2 is?
nexus9112 [7]
\bf \textit{parabola vertex form with focus point distance}\\\\&#10;\begin{array}{llll}&#10;(y-{{ k}})^2=4{{ p}}(x-{{ h}}) \\\\&#10;\boxed{(x-{{ h}})^2=4{{ p}}(y-{{ k}})} \\&#10;\end{array}&#10;\qquad &#10;\begin{array}{llll}&#10;vertex\ ({{ h}},{{ k}})\\\\&#10;{{ p}}=\textit{distance from vertex to }\\&#10;\qquad \textit{ focus or directrix}&#10;\end{array}\\\\&#10;-------------------------------\\\\&#10;y=\cfrac{1}{8}x^2\implies (y-0)=\cfrac{1}{8}(x-0)^2\implies 8(y-0)=(x-0)^2&#10;\\\\\\&#10;4(2)(y-0)=(x-0)^2\impliedby \textit{that means, p = 2}

so... if you notice, the vertex is at h,k and that'd be the origin, 0,0

so...since the directrix is "p" units from the vertex, so it'd be 2 units from 0,0

now, the parabola has an equation with a positive leading term's coefficient, namely the 1/8 is positive, thus, the parabola is opening upwards, and the directrix is "outside" the parabola, so is below the vertex

that puts the directrix 2 units below 0,0

y = -2
