​

Answer:

2.8 < x -0

Step-by-step explanation:

Answer:

2 is A. no solution

3 is C.  6

Step-by-step explanation:

Answer:

None of them are correct

Answer:

x = ±6

General Formulas and Concepts:

Pre-Algebra

Algebra II

Step-by-step explanation:

Step 1: Define

-x² = -36

Step 2: Solve for x

Step 3: Check

Plug in x to verify it's a solution.

Here we see that both -6 and 6 do indeed work as solutions.

∴ x = ±6 are both solutions to the equation.

Answer:

x=27

∠JLK=2x+1=2(27)+1=55

Step-by-step explanation:

∠A+∠K=180

3x+13+∠K=180

∠K=167-3x

∠K+∠L+∠J=180

167-3x+39+2x+1=180

207-x=180

x=27

∠JLK=2x+1=2(27)+1=55

Don't worry, you aren't gonna fail. Take a deep breath and relax. Geometry is tricky but you got this. Have a nice night.

Answer:

Step-by-step explanation:

∠AKL is exterior angle and as per property it is equal to sum of two non-adjacent angles:

Solving for x

Answer:

Answer: 14%

Step-by-step explanation:

From the question, we are informed that Bobby guessed there were 92 jelly beans in a jar when there were actually 107. The percentage error will be:

= Difference in error / Actual value × 100

= (107 - 92) / 107 × 100

= 15/107 × 100

= 0.14 × 100

= 14%

Answer:

The correct option is;

0.01 and (1 × 1/100)

Step-by-step explanation:

The given parameters includes;

The batting average of Yordan Alvarez's = 0.317

Therefore, we have;

The digit in the hundredths place = 0.01

The expanded notation for the value of the hundredth place is given by the product of the digit and the place value digit as follows;

The expanded notation = 1 × 1/100.

Answer:

x ≥ - 3

Step-by-step explanation:

Step 1:

- 7x - 13 ≥ 8       Equation

Step 2:

- 7x ≥ 21      Add 13 on both sides

Step 3:

x ≥ 21 ÷ - 7      Divide

Answer:

x ≥ - 3

Hope This Helps :)

Answer:     x≤−3

Step-by-step explanation:

So first you  -7*x-13-(8)≥0

then you are supposed to pull out like the factors  -7x - 21  =   -7 • (x + 3)

then you divide both sides by -7 then you flip the inequality sign remember that :). then subtract 3 from both sides. and then you got  x ≤ -3 So I really hoped this helped :)

Answer:

54

Step-by-step explanation:

What the shorthand is telling you is wherever you see an x on the right, you put in -8

f(x) = 6(1- x)

f(-8) = 6(1 - - 8)

f(-8) = 6(1+8)

f(-8) = 6*9

f(-8) = 54

Answer:

I got 5^10 x 2^14 x 3

Step-by-step explanation:

1. Do a tree to find 480 as a product of its prime factors

2. You should get 480= 5x2x3x2x2x2x2

3. 10 expressed as a product of its prime factors is 5x2

4. so 10^9 expressed as a product of its prime factors would be

5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2

5. You can then write out 480x10^9 as a product of its prime factors

5x2x3x2x2x2x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2

6. change this to use powers

5^10 x 2^14 x 3

N = 5^(10) × 2^(14) × 3

This is about prime factors

By definition, a prime factor is a factor of a number and that factor is also a prime number.

A prime number is one that is divisible by only itself and 1.

The number we have is; 480 × 10^(9)

Now, let's list the prime factors or 480 and they are;

2, 3, 5

Now, using these prime factors alone to get 480, we have;

5 × 3 × 2 × 2 × 2 × 2 × 2 = 480

In powers, gives;

5 × 3 × 2^(5)

Now,the 10^(9) with the 480 can also be expressed in terms of it's prime factors which are 2 and 5 as;

(5 × 2)^(9)

Expanding this gives; 5^(9) × 2^(9) = 10^(9)

Thus;

480 × 10^(9) = 5 × 3 × 2^(5) × 5^(9) × 2^(9)

This gives;

5^(10) × 2^(14) × 3

Answer:

The number of student ticket sold is 40

Step-by-step explanation:

Given;

total number of tickets sold,= 56 tickets

total amount the tickets were sold, = $328.

cost of student tickets, = $5

cost of adult ticket,  = $8

Let the number of student ticket sold = x

Let the number of adult ticket sold = y

To determine the number of student tickets sold, we will have the following equations;

x + y = 56 ------ equation (1)

5x + 8y = 328 -----equation (2)

from equation (1), y = 56 - x

Substitute the value of y in equation (2);

5x + 8y = 328

5x + 8(56 - x) = 328

5x + 448 - 8x = 328

5x - 8x = 328 - 448

- 3x = - 120

x = 120 / 3

x = 40

Therefore, the number of student ticket sold is 40

Answer:

a) (-2,-1)

b) (-3,0) (-1,0)

Step-by-step explanation:

It tells you on the graph

Answer:

a) I think the turning point is max or min correct? If so, the min of the function is (-2, -1) AKA the vertex

b) I also think the roots are just another way to say the x-intercepts so in that case, the roots are (-1, 0) and (-3, 0)

Okay so not super crazy but one night me, my brothers, my cousin, and a few friends from our campground stayed up all night and walked in the rain. Not the crazy part though obviously. It was pouring and we got to the complete opposite side of the camp and through the woods and thought it was a good idea to go to the 'abandoned bathrooms" at like 2 in the morning. So we walked through the woods and made it there, we then found that someone boarded it up so you couldn't enter the bathrooms anymore. My older brother found a crowbar on the ground and beat the hecc out of the boys side boards until we could go in. We went in and messed around for a bit. We didn't make it home until the early hours of the morning. It was really fun and we got to scare my cousin lol
