Answer:

-54

Step-by-step explanation:

first fill in the numbers

next do the parentheses 17 + 21=38

then find -8×2 which equals -16

then subtract -16 from 38 and get -54

The value of the expression a² - (b + c) at a = -8, b = 17, and c = 21 will be 26.

When the relevant factors and natural laws of a mathematical model are given values, the outcome of the calculation it describes is the expression's outcome.

Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.

The expression is given below.

⇒ a² - (b + c)

The value of the expression at a = -8, b = 17, and c = 21 will be

⇒ a² - (b + c)

⇒ (-8)² - (17 + 21)

⇒ 64 - 38

⇒ 26

The value of the expression a² - (b + c) at a = -8, b = 17, and c = 21 will be 26.

Answer:

The average rate of change on the given interval is 9/70

Step-by-step explanation:

Here, we are to find the average rate of change of the function on the given interval

We proceed as follows;

on an interval [a,b] , we can find the average rate of change using the formula;

f(b) - f(a)/b-a

From the question;

a = 0

b = 3

f(0) = -3/5

f(3) = -3/14

Substituting the values, we have;

-3/14-(-3/5)/3-0

= 3/5-3/14/3

= (42-15)/70/3

= 27/70/3

= 27/70 * 1/3 = 9/70

Answer:

C. 12x

Each box has 12 envelopes.

The number of total envelopes will be the number of envelopes in a box multiplied by the number of boxes. The number of boxes is unknown, so it is replaced by the variable. This gives us 12x

Answer:

12

The x-axis is the horizontal one. The full coordinate is (12, 0), which the x-coordinate (or x-intercept) is 12.

Answer:

Step-by-step explanation:

if you look at the graph 0-3 is positive

so that gives us 3+

3-2(you count 3 to -2 is negative since it goes left

Answers:

Probability of landing all three coins on head: [tex]\frac{1}{8}[/tex]

Probability of landing all three coins on tail: [tex]\frac{1}{8}[/tex]

Probability of landing two coins on head and one on tail: [tex]\frac{3}{8}[/tex]

Probability of landing two coins on tails and one on head: [tex]\frac{3}{8}[/tex]

Step-by-step explanation (Read Carefully):

-How to calculate this is that there are three possible outcomes when tossing the three coins. So, if you group all the possible outcomes of heads and tails when tossing the three coins in one event, you’ll get eight events. Let’s take a look at it:

-A way to organize this is to have:

H = heads

T = tails

-Total of eight events, where each event is the probability of the three coins being tossed (possible events with equal probability, and order matters):

HHH

HHT

HTH

HTT

THH

THT

TTH

TTT

Now, let’s apply some questions:

⇒ Probability of landing all three coins on heads: [tex]\frac{1}{8}[/tex]

Explanation: Look at the events above. How many times (out of the eight events) that all three coins land on heads? Well, you can see that there is only one possible event that has HHH. So, the probability of landing all three coins on heads (out of the eight events) is [tex]\frac{1}{8}[/tex].

⇒ Probability of landing all three coins on tails: [tex]\frac{1}{8}[/tex]

Explanation: Look at the events above. How many times (out of the eight events) that all three coins land on tails? Well, you can see that there is only one possible event that has TTT. So, the probability of landing all three coins on tails (out of the eight events) is [tex]\frac{1}{8}[/tex].

⇒ Probability of landing two coins on heads and one on tails: [tex]\frac{3}{8}[/tex]

Explanation: Look at the events above. How many times (out of the eight events) where two coins land on heads and one on tails? Well, you can see that there are three possible events that include HHT, HTH, THH. So, the probability of landing two coins on heads and one on tails (out of the eight events) is [tex]\frac{3}{8}[/tex].

⇒ Probability of landing two coins on tails and one on heads: [tex]\frac{3}{8}[/tex]

Explanation: Look at the events above. How many times (out of the eight events) where two coins land on tails the one on heads? Well, you can see that there are three possible events that include HTT, THT, TTH. So, the probability of landing two coins on tails and one on heads (out of the eight events) is [tex]\frac{3}{8}[/tex].

Answer:

I think C.

Step-by-step explanation:

Answer: maybe c?

Step-by-step explanation:

from eqn. 1

3x + 2y = 23

2y = 23 - 3x

y = 23/2 - 3/2x

sub into eqn. 2

1/2x - 4 = 23/2 - 3/2x

1/2x + 3/2x = 23/2 + 4/1

2x = 23/2 + 8/2

2x = 31/2

x = 31/4

sub into eqn. 1

31/4 + 2y = 23

2y = 23 - 31/4

2y = 92/4 - 31/4

2y = 61/4

y = 61/8 or 7 5/8  

ummm i got something wrong but try c?

Answer:

C . 31/4,-1/8

Step-by-step explanation:

1. sub the given value of y

into 3x + 2 (1/2x -4) 23

2. slove for x = 31/4

3.sub the given value of x into 1/2x - 4 =y

4. solve the equation for y

5. y = -1/8

6. ordered pair to (x,y) = 31/4,1,8
