O 15
O 25
O 53
O 125

Answers

Answer 1

Answer:

125

Step-by-step explanation:

If the function is f(x) = 5^x and you need to know the value of f(3), you just need to put 3 in place of x:

f(3) = 5^3 = 5•5•5 = 125

Determine whether each pair of segments is congruent.

Plz can someone help me

Answers

Answer:

23. Congruent

24. Not congruent

Step-by-step explanation:

23. KJ and HL:

Since the side lengths are both 4 in, these segments are congruent.

24. EH and FG:

Since the side lengths are different numbers (0.45 cm and 0.5 cm), these segments are not congruent.

The answer is KJ and HL. Only the first one is congruent because both lines EH and FG don’t have sides with equal measurement.

The slope is the “change in y over the change in x,” also referred to as “rise over run.”

Pick any two points and calculate the difference in their y-values and divide that by the difference in their x-values.

Notice that all y-values are the same, so your “change in y” or your “rise” is always 0.

0/anything = 0 (as long as the denominator isn’t 0)

So, your slope here is 0.

Sarah counted the number of tiles at each step and made a table. She explained that the
number of tiles in each figure was always 3 times the step number minus 2.

Create an equation that fits Sarah's way of seeing the relationship.

PLS HELP DUE IN 10 min!!

Answers

Answer:

n(number of tiles) x 3 - 2

Step-by-step explanation:

times mean multiplication and minus mean subtraction, I hope this helps.

An equation is formed of two equal expressions. An equation that fits Sarah's way of seeing the relationship is y = 3x - 2.

What is an equation?

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

As stated by Sarah that "the number of tiles in each figure was always 3 times the step number minus 2", this can be written in the form of an equation as shown below.

Number of tiles = [3 × (Number of steps)] - 2

Assume that the number of tiles is represented by y, while the number of steps can be written as x. Therefore, we can write the equation as,

y = 3x - 2

Now, let's check the equation,

When the number of steps is 3, the number of tiles is 7.

y = 3(3) - 2

y = 9 - 2

y = 7

Since the number of tiles is the same, therefore, the equation is correct.

Hence, an equation that fits Sarah's way of seeing the relationship is y = 3x - 2.

Step-by-step explanation:

Given

(3x² - 4x - 5)(- 2x² + 2x + 2)

Each term in the second factor is multiplied by each term in the first factor, that is

3x²(- 2x² + 2x + 2) - 4x(- 2x² + 2x + 2) - 5(- 2x² + 2x + 2) ← distribute parenthesis

= - 6[tex]x^{4}[/tex] + 6x³ + 6x² + 8x³ - 8x² - 8x + 10x² - 10x - 10 ← collect like terms

Answers

1/3(21y+39)=-26 can be simplified into

7y +13 = -26

Next, subtract 13 from both sides

7y= -39

Now divide both sides by 7

Your answer is y=-39/7

Answer:

y = -7

Step-by-step explanation:

1/3 (21y+39) = -36

Distribute

7y +13 = -36

Subtract 13 from each side

7y+13-13 = -36-13

7y = -49

Divide each side by 7

7y/7 = -49/7

y = -7
