i’m stuck please help

Answers

Answer 1

You divide 3 on both sides then you equation is the square root of -4x-4 =4 and you square the number on both sides because u need to do the same things on both sides and you get -4x-4=16 subtract by 4 on boyh sides to get -4x=20 and divide by -4 on both aises to get x=-5

I hope this helped i know this explanation is a bit wonky

A plane flew 720 miles in 6 hours. How many miles did the plane fly in 4 hours?

Answers

Answer:

[tex]\huge\boxed{\texttt{480 miles}}[/tex]

Step-by-step explanation:

We can create a ratio here to find the constant of proportionality and use that to find how many miles the plane flew in 4 hours.

We know the plane flew 720 miles in 6 hours. We can create a ratio, represented as a fraction, in the form [tex]\frac{miles}{hours}[/tex] .

[tex]\frac{720}{6}[/tex]

We can now make another ratio where we use a variable for the miles flown in 4 hours.

[tex]\frac{x}{4}[/tex]

Since the ratios are equal, we can create an equation.

[tex]\frac{720}{6}=\frac{x}{4}[/tex]

To find the value of x, let's cross multiply.

[tex]720 \cdot 4 = 2880\\\\2880\div 6 = 480[/tex]

So the plane flew 480 miles in 4 hours.

Hope this helped!

Find the error and explain what the correct step should be

Answers

Answer:

m = 12, the error was that the student did not divide both sides by -. so they got the incorrect answer

Step-by-step explanation:

okay, so you want to get m

because m is divided by 3, to counter it, you multiply both sides by three

-m/3 = -4

-m/3 times 3 =-4 times 3

because 1/3 times 3 =1, and -4 times 3 = -12, you get

-m = -12

then, divide both sides by - (because you want positive m)

and you get m = 12

the error was that the student did not divide by the negative, so in the end, their sign was wrong.

Angela lives 0.6 mile from the park. It takes her hour to walk her dog to the park. How quickly are Angela and her dog walking in miles per hour?

Answers

Answer:

0.6 miles an hour

Step-by-step explanation:

since it takes her 0.6 miles to walk an hour and an hour to walk 0.6 miles.

0.6 = 3/5

Answer: 0.1 miles per hour

Since an hour has 6 10-minute segments, divide by 6.

0.6 ÷ 6 = 0.1

Your answer should be 0.1 miles per hour.

So, Angela and her dog are walking at 0.1 miles per hour.

The required function [f o g(x)] is -7/√(x + 3).

The domain of the function [f o g(x)] > - 3.

What is a function?

A function is the relation between two sets. The first one is called domain and the second one is called range.

Given, f(x) = - 7/x

g(x) = √(x + 3)

Therefore, f o g(x)

= f[g(x)]

= f[√(x + 3)]

= -7/√(x + 3)

Now, the domain of f o g(x) > - 3.

Answer:

For the first section, you write the algebraic expression or equation that goes with the statement.

For example, 9 more than the product of 51 and number "i" would translate into 51i+9. More and sum refers to addition, difference is subtraction, and quotient is division.

For the second section, you just simplify each of the expressions. when a number has ^, that means it has the square root, so 9^2 would be nine squared, which is 81.

For the third section, replace the c values for 3 and the d values for 5.

For the fourth section, determine whether or not each number is rational by writing the number as a fraction where both numerator and denominator are whole numbers. Pi is irrational as it can't be written as the fraction of 2 integers

For the last section, combine like terms and explain each step.
