Step 1: Define
y = -4x² - 8
x = 2
Step 2: Solve
Substitute: y = -4(2)² - 8Evaluate: y = -4(4) - 8Multiply: y = -16 - 8Subtract: y = -24Answer:
Given, input (x) is 2,
[tex]y = -4x^2 - 8\\y = -4(2)^2 - 8\\y = -4(4) - 8\\y = -16 - 8\\y = -24[/tex]

What is the slope of у= 3х — 9
Answer:
3
Step-by-step explanation:
We can recognize this equation as a linear equation, which is given by the following formula:
[tex]y=mx-b[/tex], where m is the slope and b is the y-intercept.
Thus, we see that 3 is the slope, and 9 is the y-intercept.
Alto's dove 9 meters below the ocean's surface. She then dove 15 meters deeperShe then rose 19 1/4 meters. What was her position in realtion to the surface of water?
Answer:
Alto was 4.75 meters under the water, or -4.75.
Step-by-step explanation:
Alto dove 9 meters and then 15 meters. We can add those two which is 24 meters. Then she rose 19 and 1/4, so we have to subtract that from 24.

All 40 turkeys are in a pen. 1/4 are sleeping. 1/8 are eating, and 5/8 of them are hiding from the butcher. How many are sleeping How many are eating How many are hiding
Answer:
[tex]Sleeping = 10[/tex]
[tex]Eating = 5[/tex]
[tex]Hiding =25[/tex]
Step-by-step explanation:
Given
[tex]Turkey = 40[/tex]
[tex]Sleeping = \frac{1}{4}[/tex]
[tex]Eating = \frac{1}{8}[/tex]
[tex]Hiding = \frac{5}{8}[/tex]
Required
Determine the number in each category
To solve this, we simply multiply each fraction by the total number of turkey:
[tex]Sleeping = \frac{1}{4} * 40[/tex]
[tex]Sleeping = \frac{40}{4}[/tex]
[tex]Sleeping = 10[/tex]
[tex]Eating = \frac{1}{8} * 40[/tex]
[tex]Eating = \frac{40}{8}[/tex]
[tex]Eating = 5[/tex]
[tex]Hiding = \frac{5}{8} * 40[/tex]
[tex]Hiding = \frac{200}{8}[/tex]
[tex]Hiding =25[/tex]

Write the equation of the line passing through (2,3) and perpendicular to y = 2/3 x + 7.
Answer:
y = 2/3x
Step-by-step explanation:
So we know, when lines are perpendicular that they share the same slope. The slope in the equation of y = 2/3x + 7 is 2/3x. So, we have our slope. Now, we just need to find our b. We plug in the point that you gave us into the equation y = mx + b.
3 = 2/3(2) + b
we multiply the denominator 3 by 2, then divide that by the numerator 2.
3 = 3 + b
subtract 3 from itself and from the opposite side of the equal side 3.
0 = b
in the end, there is no b for this equation. Our answer is
y = 2/3x

What is the rectangular form of 17(cos(315°) + isin(315°))?
The value of the expression 17[cos(315°) + isin(315°)] will be (17√2 / 2) – (17√2 / 2)i. Then the correct option is A.
What is trigonometry?The connection between the lengths and angles of a triangular shape is the subject of trigonometry.
The rectangular form of 17(cos(315°) + isin(315°)).
We know that the value of cos 315° and sin 315°.
[tex]\sin 315^o = \dfrac{-1}{\sqrt2}\\\cos 315^o = \dfrac{1}{\sqrt2}[/tex]
Then the value of the expression will be
⇒ 17[(1/√2) – (1/√2)i]
⇒ (17√2 / 2) – (17√2 / 2)i
Then the correct option is A.

Si dividimos una pizza el cuarto partes iguales y dividimos una de estas partes en dos partes iguales¿Cuál es la fracción que representa una de estas partes más pequeñas?
Answer:
[tex]\frac{0.5}{4}[/tex]
Step-by-step explanation:
An entire pizza would be represented by the percentage of 100% or the fraction [tex]\frac{100}{100}[/tex]. If we divide this pizza into 4 equal parts that would make one slice a fraction represented as [tex]\frac{25}{100}[/tex] or simplified to [tex]\frac{1}{4}[/tex]. If we now divide this one slice into two equal parts we would divide that fraction by 2 which would give us a new fraction, which would be [tex]\frac{0.5}{4}[/tex]. Represented as a percentage this would mean that this slice is 12.5% of the entire pizza.

pair of shoes that has a wholesale cost of $67?
Answer:
$93.8
Step-by-step explanation:
(*markup is an increase in price)
67 + ( 40% × 67 )
= 67 + ( 40/100 × 67/1 )
= 67 + 26.8
= 93.8

Answer:
C=25n+4300
Step-by-step explanation:
Given that,
Last year, Pinwheel Industries introduced a new toy. It cost $4 ,300 to develop the toy and $25 to manufacture each toy.
We need to write a linear equation in the form C=mn+b that gives the total cost, C, to produce n of these toys.
Here, m will be cost for each toy and b is the cost to develop each toy. So,
C=25n+4300
Hence, this is the required solution.

To make homemade whipped cream the recipe calls for 1 ½ C of heavy cream, 1 ¼ t of vanilla, and 1 t. of sugar. This amount of whipped cream would be enough to cover one pie. If K makes 6 pies and covers them with whipped cream, how many teaspoons of vanilla will he need?
Answer:
7 1/2 teaspoons of vanilla
Step-by-step explanation:
From the above question,
The whipped cream for 1 pie contains
1 1/4 teaspoon of vanilla
Hence:
1 pie = 1 1/4 teaspoon of vanilla
6 pies = x
Cross Multiply
x = 6 × 1 1/4
x = 6 × 5/4
x = 30/4
x = 7 2/4
x = 7 1/2 teaspoons of vanilla
Hence: If K makes 6 pies and covers them with whipped cream, he would be needing 7 1/2 teaspoons of vanilla

Joseph has 48 comic books. He sold one-fourth of his collection to his friend. He brought twice the number of comic books as he has now.how many comic books does he have now?
Answer:
108
Step-by-step explanation:
Given that Joseph has 48 comic books.
As he sold 1/4 of his collection to his friend, so
The number of books, Josef sold = 1/4 x 48 = 12.
The number of remaining books, Josef has = 48 - 12 = 36.
As he brought twice the number of comic books as he has now, so,
the number of comic books, Josef brought = 2 x 36 = 72.
Now, total number of comic books, Josef has = 36 + 72 = 108.
