260 should be correct.

General Formulas and Concepts;

Pre-Algebra

Order of Operations: BPEMDAS

Step-by-step explanation:

Step 1: Define expression

6² · (16 + 19) - 10³

Step 2: Evaluate

Answer:

It's 260, maybe the system is wrong?

Step-by-step explanation:

6^2(16+19)-10^3

add the numbers in the parentheses

6^2(35)-10^3

simplify the exponents first

36(35)-1000

1260 - 1000

260

Answer:

=29

Step-by-step explanation:

2f(b)=28

divide by 2

f(b)=14

f(b)=3b-1

3b-1=14

add 1 on both sides

3b=15

divide by 3

b=5

f(5)=14

let's plug that in

f(2×5)=3(2×5)-1

f(10)=30-1

f(10)=29

The value of f(2b) is 29 if f(x) = 3x - 1 and 2f(b) = 28 the answer is 29.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have:

f(x) = 3x - 1 and 2f(b) = 28

Plug x = b

f(b) = 3b - 1

2f(b) =2(3b - 1)

2f(b) = 28

28 = 2(3b - 1)

b = 5

f(2b) = f(2(5)) = f(10)

f(10) = 3(10) - 1

f(10) = 30 - 1 = 29

Thus, the value of f(2b) is 29 if f(x) = 3x - 1 and 2f(b) = 28 the answer is 29.

Answer:

Slope equals to 3

Step-by-step explanation:

-2-7=-9 over 5-8=-3. You then divide the 9 by 3 and because they are both negative they equal a positive.

Answer:

9.3

Step-by-step explanation:

9.3 is greater because 9.3 has a bigger value than .84 because .84 is in the hundredths place which is less than the unit digit which is 9 from 9.3

Answer:

3/-7

Step-by-step explanation:

Using the equation [tex]M=\frac{Y_{2}-Y_{1}}{X_{2}-X_{1}}[/tex] where M is slope, you take (1--2) 1+2/1-8 and you get 3/-7.

Answer:

A (-3, 2.5)

Step-by-step explanation:

Midpoint formula is m=(x1 + x2/2), (y1 + y2/2)

So add the xs: -5 + -1 = -6

And the ys: 1 + 4 = 5

Then divide them by 2

(-3, 2.5)

Answer:

The ladder must be placed at a distance of 33.2 feet from the bottom of the building

Step-by-step explanation:

From what we have here, we are looking at a right angled triangle with the hypotenuse which is the length of the ladder

The height of the child is 50 feet from ground level

So we need to get the third side of the triangle

We can get this by considering the use of Pythagoras’ theorem

This will give us the length of the third side of the triangle

From Pythagoras’ the square of the hypotenuse is equal the sum of the squares of the two other sides

Let the unknown side be x

Thus;

60^2 = 50^2 + x^2

x^2 = 60^2 - 50^2

x^2 = (60-50)(60+50)

x^2 = (10)(110)

x^2 = 1100

x = square root of 1100

x = 33.166

To the nearest tenth, this is 33.2 feet

Answer: A

Step-by-step explanation: If you fill in the x-intercept and the y-intercept and solve -4(2) + 20 = 12       And -4(3) + 20 = 8    

if you solve for those you would get your y-intercept

Answer:

When raising a power to a power in an exponential expression, you find the new power by multiplying the two powers together. For example, in the following expression, x to the power of 3 is being raised to the power of 6, and so you would multiply 3 and 6 to find the new power.

Answer:

A. (-3, 2)

Step-by-step explanation:

First step is to revert the equation into y = mx  + b form.

-4x + 2y = 16 turns into y = 2x+8

Now just plug in the points given to see which one matches.

(-3,2) the x is -3 so if you plug that into the equation it should get you 2 which is the y.

2 = 2(-3) + 8

2 = 2

So we know that (-3, 2) is the solution.

If you plug in the other points they wont come out equal. For example, (4,-1)

-1 = 2(4) + 8

-1 = 16

So (4,-1) cant be a solution. The same thing applies for (2, -3).
