Answers
Which system of equation can represent the equation?
Answers
log(x+3)
y₁ = --------------
log(4)
log(2 + x)
y₂ = ----------------
log(2)
Explanation:
1) Here you must use the property named change of base of the logarithm.
That rule is:
[tex]log_{a}b= \frac{log_c{b}}{log_ca} [/tex]
2) Changing to base 10 that is:
[tex]log_{b}a= \frac{loga}{logb} [/tex]
3) Using it with the given equation, you get:
[tex]log_4(x+3)= \frac{log_(x+3)}{log(4)} log_2(2+x)= \frac{log(2+x)}{log(2)}[/tex]
4) Now, to set your system you can make the left side of the equation equal to y₁ and the right side equal to y₂
log(x+3)
y₁ = -------------
log(4)
log(2 + x)
y₂ = ---------------
log(2)
And that is your system which is the first choice of the list.

The weather report says there is an 85% chance it will be very hot tomorrow. Should you get ready to use the air conditioner? Explain.
Answers
Based on the 85% chance of very hot weather, it is reasonable to prepare to use the air conditioner. Weather forecasts with high probabilities can guide us in making practical preparation decisions for comfort and safety.
The weather report indicates there is an 85% chance that it will be very hot tomorrow. Given this high probability, it would be reasonable for you to prepare to use the air conditioner. Decisions based on weather forecasts often involve considering the likelihood of different outcomes and planning accordingly.
Weather is the atmospheric conditions at a particular place over a short period of time, and preparing for it helps us manage daily activities and comfort levels. When the probability of a specific weather event, such as extreme heat, is high, it is generally wise to prepare for that scenario. By planning to use the air conditioner, you can ensure you're able to maintain a comfortable environment during the hot weather.

x+2= larger integer
Add the integers

2x + 2= 234
subtract 2 from both sides
2x= 232
divide both sides by 2
x= 116 smaller integer
x+2= 118 larger integer

ANSWER: The larger consecutive even integer is 118.
Hope this helps! :)
The other number will be x + 2.
Sum of the 2 numbers is 234.
x + x + 2 = 234

Justin is exchanging dollars for rolls of quarters and rolls of dimes at a bank. Each roll of quarters has a value of $10 and each roll of dimes has a value of $5. He exchanges $90 and receives 11 rolls of coins. How many of each type of roll of coins did he receive?
Answers
Answer:
Justin got 7 rolls of quarters and 4 rolls of dimes.
Step-by-step explanation:
Let the roll of quarters be x
Let the rolls of dimes be y
As total money received is $90, the equation becomes;
[tex]10x+5y=90[/tex] .....(1)
And he got 11 roll of coins, so equation becomes;
[tex]x+y=11[/tex] or [tex]x=11-y[/tex] .... (2)
Substituting the value of x from (2) in (1)
[tex]10(11-y)+5y=90[/tex]
[tex]=> 110-10y+5y=90[/tex]
[tex]=> -5y=-110+90[/tex]
[tex]=> -5y=-20[/tex]
So, y = 4
As [tex]x=11-y[/tex]
So, [tex]x=11-4[/tex]
x = 7
Hence, Justin got 7 rolls of quarters and 4 rolls of dimes.

Answers
-x² + 9 + (-3x² - 11x + 4)
Now,, remember that when there is a "+"sign in front of the parenthesis,, then the parenthesis in the expression remains the same. This means that all you need to do for the second side of the expression is remove the parenthesis.
-x² + 9 + -3x² - 11x + 4
Collect the like terms that have an exponent of two.
-4x² + 9 - 11x + 4
Add the regular numbers together.
-4x² + 13 - 11x
Lastly,, use the commutative property to reorder the terms and get your final answer.
-4x² - 11x + 13
Since we cannot simplify this expression down any further,, our final answer is going to be -4x² - 11x + 13 or option B.
Let me know if you have any further questions.

Which word best describes 8(2x +4)
Answers
Final answer:
The word that best describes 8(2x + 4) is multiplication. When we multiply a number by an expression, we distribute the multiplication to each term in the expression. Simplifying further, 8(2x + 4) becomes 16x + 32.
Explanation:
The word that best describes 8(2x + 4) is multiplication. In this expression, the number 8 is being multiplied by the expression 2x + 4. When we multiply a number by an expression, we distribute the multiplication to each term in the expression. Therefore, the expression becomes 8 * 2x + 8 * 4.
Simplifying further, we get 16x + 32. So, the word that best describes 8(2x + 4) is multiplication.
The table shows the results of spinning a spinner several times. (Don’t mind my answer)
Answers
The experimental probability of spinning a B or a C is [tex]\( \frac{1}{4} \)[/tex].
To find the experimental probability of spinning a B or a C, we need to sum up the frequencies of outcomes B and C and then divide that by the total number of spins.
Given frequencies:
Outcome A: 3
Outcome B: 2
Outcome C: 1
Outcome D: 4
Outcome E: 2
Total frequency of B and C: 2 (from outcome B) + 1 (from outcome C) = 3
Total number of spins: Sum of all frequencies = 3 + 2 + 1 + 4 + 2 = 12
Experimental probability of spinning a B or a C: [tex]\(\frac{\text{Total frequency of B and C}}{\text{Total number of spins}} = \frac{3}{12} = \frac{1}{4}\)[/tex]
So, the experimental probability of spinning a B or a C is [tex]\(\frac{1}{4}\)[/tex].
