Thank you to anyone who answers !! :-)
Answers
Answer:
C.) 3 and -3
Step-by-step explanation:
The question is asking: "Which numbers can be multiplied by themselves and equal 9?" You can formally find this answer by taking the square root of 9, the opposite of squaring a number. Or, in this case, you can try the guess-and-check method. Remember, multiplying two negative numbers together results in a positive answer.
A.) is incorrect because 81 x 81 = 6561 and -81 x -81 = 6561.
B.) I'm assuming this answer is [tex]\sqrt{3}[/tex] (if it's not, there is still a better answer). This answer is incorrect because [tex]\sqrt{3}[/tex] x [tex]\sqrt{3}[/tex] = 3.
C.) is correct because 3 x 3 = 9 and -3 x -3 = 9.
D.) is incorrect because -3² also equals 9.

what is x in 2x − 3 + 4x = 21
Answers
Answer: x = 4
Step-by-step explanation:
2x - 3 + 4x = 21
6x - 3 = 21
6x - 3 (+3) = 21 (+3)
6x = 24
24/6
x = 4
2x + 4x = 21 - 3
Then simplify
6x = 18
Then divide 6 to both sides to find x
X=3

which equation represents a linear function 2ry+y= 9 , y=12r-5 , 3y+r2+t=0, 4r+2(y-1)=0
Answers
The equation which represents a linear function for the variable y is y=12r-5. Option B is the correct option.
What is linear function?Linear function is the function in which the highest power of the unknown variable is one. Linear functions are used to model the real life problem in the mathematical expressions.
The linear function with dependent variable y and independent variable x can be written as,
y=mx+c
Here, m is the slope of the line represented by the function and c is the y intercept.
The equation given in the problem are,
2ry+y= 9
y=12r-5
3y+r2+t=0
4r+2(y-1)=0
The second option is similar to the standard linear function.
Hence, the equation which represents a linear function for the variable y is y=12r-5. Option B is the correct option.

Answers
The Venn probability that a a day in early March would have either rain or snow is given by:
4.) .26
What is a Venn probability?In a Venn probability, two non-independent events are related with each other, as are their probabilities.
The "or probability" is given by:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]
In this problem, we have that the probabilities are given as follows:
[tex]P(A) = 0.18, P(B) = 0.12, P(A \cap B) = 0.04[/tex]
Hence:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]
[tex]P(A \cup B) = 0.18 + 0.12 - 0.04[/tex]
[tex]P(A \cup B) = 0.26[/tex]
Which means that option 4 is correct.

Find the value of x in the figure.
Answers
Step-by-Step Explanation:
In the Figure, both the Angles form a Linear pair which means they sum up to 180 degrees.
Therefore,
57 + x + 23 = 180
57 + 23 + x = 180
80 + x = 180
x = 180 - 80
=> x = 100
Therefore, x = 100
Also finding the missing Angle :-
= x + 23
= 100 + 23
=> 123
The Angle is 123 degrees.
