X = 10/11, good luck my dude

What are the solutions to the quadratic equation 4(x + 2)2 = 36
x= -11 and x = 7
x = -7 and x = 11
OOOO
x= -5 and x = 1
x= -1 and x = 5

Answers

Answer:

x = -5 and x = 1

Step-by-step explanation:

4( x2 + 4x + 4 ) = 36

4x2 + 16x + 16 = 36

4x2 + 16x - 20 = 0

x2 + 4x - 5 = 0

Answer:

C. x = -5, and x = 1

Step-by-step explanation:

You have the equation 4(x + 2)2 = 36

You then isolate 4 out of the equation using division on both sides

You are left with (x+2)2 = 9

Next, take square roots

[tex]\sqrt({x} +2) ^{2}[/tex] = [tex]\sqrt{9}[/tex]

This leaves you with x + 2 ± 9

So, x = -2 + 3 = 1

or

x = -2 - 3 = -5

OER type of question.
The system of linear equations is below.
2x – 3y = 15
-2x + y = -1
It has on it that the two ways it can be solved are 'Substitution or Elimination'.
The Academic Language we are supposed to use is below.
Elimination, Substitution, Graphing, Intersection, Solution, Coordinate Point, Ordered Pair, Solve, Isolate, Systems, Equations, Additive Inverse, Multiplicative Inverse, Distributive Property, Variable, Combine Like Terms, and Justify.

Don't know if anyone can help me with this but I am really bad at OERs and I am hoping that someone can help with this so I can somewhat pass my class.

Answers

Answer:

x=-3, y=-19

Step-by-step explanation:

we can solve by substitution.

y = 2x-1 we can derive from the second equation.

plugging it into the first equation, 2x -3(2x-1) = 15.

simplying, 2x-6x+3 = 15 --> -4x+3 = 15, -4x = 12, x = -3.

now we know x, so we can solve for y by plugging it into one of the equations. --> -3*-6+y = -1

simplify, 18+y = -1 --> y = -19.

Pranav's school is selling tickets
to a fall musical. On the first
day of ticket sales the school
sold 12 adult tickets and 7
student tickets for a total of
$124. The school took in $20
on the second day by selling 1
adult ticket and 3 student
tickets.
What is the price each of one
adult ticket and one student
ticket?
I need the number of 2 points shots and the number of 3 points shots

Answers

Answer:

The cost of one adult ticket is $8 and cost of one student ticket is $4.

Step-by-step explanation:

Let,

x be the price of one adult ticket

y be the price of one student ticket

According to given statement;

12x+7y=124    Eqn 1

x+3y=20        Eqn 2

Multiplying Eqn 2 by 12

12(x+3y=20)

12x+36y=240     Eqn 3

Subtracting Eqn 1 from Eqn 3

(12x+36y)-(12x+7y)=240-124

12x+36y-12x-7y=116

29y=116

Dividing both sides by 29

[tex]\frac{29y}{29}=\frac{116}{29}\\y=4[/tex]

Putting y=4 in Eqn 2

x+3(4)=20

x+12=20

x=20-12

x=8

Hence,

The cost of one adult ticket is $8 and cost of one student ticket is $4.

Answers

The answer is 5b - w + 8

Step-by-step explanation:

Answer:

-w + 5b + 8

Step-by-step explanation:

Step 1: Since you're only dealing with addition and subtraction, the easiest method is to convert all subtraction to addition by adding the opposite. There is only one case of subtraction (-4w) which can be changed to adding negative 4w:

3w + 6 + (-4w) + 3b + 2 + 2b

Step 2: Combine like terms to simplify:

3w + (-4w) = -w

3b + 2b = 5b

6 + 2 = 8

Answer:

-w + 5b + 8

6. A ball is thrown at an upward velocity of 72 feet per second from a platform that is raised 10 feet
off the ground. Use the equation y = -12 + vt + h where y is the ending height of the ball, t is the
time in seconds, v is the ball's velocity, and h is the intial height, in feet, of the ball.
How long will it take the ball to reach its maximum height, and what is that maximum height?
(Disregard any extra height added by the person throwing the ball.)

Answers

Answer:

Question 675528: A ball is thrown vertically upward with an initial velocity of 48 feet per second. If the ball started its flight at a height of 8 feet, then its height s at time t can be determined by s(t)=-16t^2+48t+8 where s(t) is measured in feet above the ground and t is the number of seconds of flight.
