Step-by-step explanation:

[tex] \begin{cases} y = 3x \\\\ 2y + 2x = 24\end{cases} [/tex]

Plugging y = 3x in the equation 2y + 2x = 24, we find:

2(3x) + 2x = 24

6x + 2x = 24

8x = 24

x= 24/8

x = 3

Plugging x = 3 in the equation y = 3x we have:

y = 3*3 = 9

(x, y) = (3, 9)

Answer: the answer is 3

Step-by-step explanation: The gradient (or slope) of the tangent to a curve at any particular point is given by the derivative at that point If y = x 3 then d y d x = 3 x 2 When x = 1 ⇒ d y d x = 3 So the slope equals 3

The slope of the tangent line to the graph of each equation at x = 1. y = 3x will be 3.

A numerical assessment of a line's angle relative to the ground is known as the slope.

The inclination of any line, ray, or line segment is the fraction of the perpendicular to the horizontal distance between any two positions on it.

The slope is found by the relation;

[tex]\rm m = \frac{dy}{dx} \\\\ m= \frac{d(3x)}{dx} \\\\ m=3[/tex]

Hence,the slope of the tangent line to the graph of each equation at x = 1. y = 3x will be 3.

Answer:

$100 or y  = 7.5x + 30

I used x as it represents the cost of each friend and can be used to solve the total number of friends possible.

She can have 9 friends at her party

Step-by-step explanation:

y = 7.5x + 30

Total Amount + Cost per Friend + Total Cost of Pizza

100 = 7.5x +30

subtract 30 from each side

70 = 7.5x

divide each side by 7.5

9.33 = x

Step-by-step explanation:

adding up to 90 degrees

Step-by-step explanation:

First simplify the parentheses. [tex]4x-2x^2+x-3=-2x^2+5x-3[/tex], and [tex]x-1[/tex] can't be simplified, so the equation has now been simplified to [tex]\frac{-2x^2+5x-3}{x-1}[/tex]. The equation can be divided to equal [tex]-2x+3[/tex], so I'm guessing either there is no remainder or the 3 is the remainder.

Answer:

7√3

Step-by-step explanation:

Given the following information,

Short = 7 = Opposite

Angle of elevation =30 degrees

Required

Long (Adjacent)

Using SOH CAH TOA identity

tan theta = 7/long

tan 30 = 7/long

long = 7/tan30

long= 7/1/√3

long = 7√3

Hence the long is 7√3

Answer: I heard that you need square root 3 at the end to make it long on another question.

Answer:

a = 15yd is the answer.

Step-by-step explanation:

a = ?

b = 8yd

c = 17yd

By using the Pythagoras theorem,

a² + b² = c²

a² + 8² = 17²

a² + 64 = 289

a² = 289 - 64

a² = 225

a = 15

∴ a = 15yd is the length of the missing leg.

Step-by-step explanation:

(g o f) (-3) = g ( f(-3) )

First, let's find f(-3):

f(x)=2x²+6x+9

f(-3)=2(-3²)+6(-3)+9

f(-3)=18-18+9

f(-3)=9

Now that we know the value of f(-3), we can sub this into g(f(-3)):

g ( f(-3) ) = g(9)

Find g(9):

g(9)=3x-6

g(9)=3(9)-6

g(9)=27-6

g(9)=21

Step-by-step explanation:

Answer:

0.512 = 51.2% probability that a player defeats at least three opponents in a game

Step-by-step explanation:

Outcomes in which he defeats less than three opponents:

Lose to the first opponent: 0.2 probability.

Beats the first opponent, loses to the second: 0.8*0.2 probability

Beats the first two opponents, loses to the third: 0.8*0.8*0.2 probability:

Probability of losing before beating three opponents:

[tex]P(b < 3) = 0.2 + 0.8*0.2 + 0.8*0.8*0.2 = 0.488[/tex]

What is the probability that a player defeats at least three opponents in a game?

[tex]P(b \geq 3) = 1 - p(b < 3) = 1 - 0.488 = 0.512[/tex]

0.512 = 51.2% probability that a player defeats at least three opponents in a game
