Answer:
81
Step-by-step explanation:
Any number, wether it is negative or postive, will always be postive when there is a even exponent.
In this case, we have a -9, and a exponent thats 2.
Since 2 is a even number, -9^2 will be a postive value.
Now, what is the actual value of this?
Well, a exponent of 2 basiclly means 2 numbers being multiplied together.
Or in this case, 2 negative 9s being multiplied together.
THis will be:
-9*-9
=
As I said above, a even exponent makes a negative number postive.
You see here that a negative 9 is being multiplied by -9. When two negative numbers multiply together, they make a postive.
THis is why a even exponent makes a postive.
Hope this helps!

Answer:
Below
Step-by-step explanation:
So lets start with the first one:
-15+7
We are going to add these together, and will get -8.
Next we have:
-10+(-20)
When there is both a subtraction or negative sign, and a plus sign, the plus sign is removed.
So we can think of this as:
-10-20
And since the -10 is negative, and we are subtracting it, it is going to get more engative:
-10-20=-30
This is the solution answer.
I do not know what the answer to the plan is, i dont understand what plan means.

Answers
Answer:
a. 70 gallons of water were leaked each month.
Step-by-step explanation:
Set up an equation:
Variable x = gallons leaked each month
210/3 = x/1
Cross multiply:
210 × 1 = 3 × x
210 = 3x
Divide by 3 to isolate the variable:
70 = x
The division part is only 210 ÷ 3 = x. I wrote it down this way so you can see how I came to this equation.
Check your work:
210/3 = 70/1
210 × 1 = 3 × 70
210 = 210

A quadratic monomial with a leading coefficient of 6
A linear binomial with a leading coefficient of 2
Answers
Given:
A quadratic monomial with a leading coefficient of 6.
A linear binomial with a leading coefficient of 2.
To find:
The mathematical terms for the given statements.
Solution:
Monomial: The expression with single term.
Binomial: The expression with two terms.
Quadratic: Highest power of the variable is 2.
Linear: Highest power of the variable is 1.
Coefficient: In the product of a number and a variable, the number is known as the coefficient of that variable.
The first statement is "A quadratic monomial with a leading coefficient of 6".
Quadratic monomial means single term with degree 2. The leading coefficient of 6. So, the term is [tex]6x^2[/tex].
The second statement is "A linear binomial with a leading coefficient of 2".
Linear binomial means [tex]ax+b[/tex], where a and b are real values. The leading coefficient is 2. So, [tex]a=2[/tex].
Let [tex]b=1[/tex], then the required linear binomial is [tex]2x+1[/tex].
Therefore, a quadratic monomial with a leading coefficient of 6 is [tex]6x^2[/tex].
A linear binomial with a leading coefficient of 2 is [tex]2x+1[/tex].

The manager of a football team says the probability that the team will win the next match is 0.6 and the probability it will lose is is 0.1 Find the probability that the team will: a) not win b) not lose c) not draw
Answers
Answer:
A. 0.4
B.0.9
C.0.7
Step-by-step explanation:
Answers:
a) 0.4b) 0.9c) 0.7===========================================
Explanation:
Part (a)
P(winning) = 0.6 is given
The probability of not winning is 1 - P(winning) = 1 - 0.6 = 0.4
----------------
Part (b)
P(losing) = 0.1 is given
The probability of not losing is 1 - P(losing) = 1 - 0.1 = 0.9
-----------------
Part (c)
The probability of winning is 0.6 and the probability of losing is 0.1
This adds to 0.6+0.1 = 0.7, which must mean 0.3 is the probability of drawing (since 0.7+0.3 = 1)
So the probability of not drawing is 1 - P(draw) = 1 - 0.3 = 0.7, which is exactly the sum of the probabilities of winning and losing.

Determine whether Triangle AWT= UYZ. explain your reasoning
Answers
Answer: The triangles are congruent by the HL theorem
HL = hypotenuse leg
======================================================
Explanation:
Through the segment addition postulate, we can say:
WZ = WT+TZ
YT = TZ+ZY
Notice how both WZ and YT have TZ as part of their segments.
Since WZ and YT are the same length, we can then say,
WZ = YT
WT+TZ = TZ+ZY
WT = ZY
I used substitution for the second step.
The last step is where I subtracted TZ from both sides, and they canceled out.
---------------------
We have the following info:
WT = ZY (just found)AT = UZ (given)angle AWT = angle UYZ (given)Normally, the conclusion from here would be "not enough info" because this is a SSA case. Note how the angles are not between the congruent sides. So we wouldn't use SAS.
However, despite us having SSA, it doesn't mean we can't keep going. The reason why is because we have two right triangles. So we can use the HL theorem instead. Statement 1 above refers to the L of HL, while statement 2 is the H.
HL = hypotenuse leg
Again, HL only works for right triangles. It's the only time we can use SSA to prove right triangles are congruent; otherwise, SSA is not a valid congruence theorem.

The graph of f(x) is the solid black graph below. Which function represents the
dotted graph?
Answers
Answer: The answer is y= f(x+1)+5
Step-by-step explanation: The reason is that when you are translating the graph, the information in the parenthesis (In this case: (x+1)) is always on the x axis moving either left or right. You just go one in the opposite direction of what the sign is, so since the sign in the parenthesis is "+" you would go left in the opposite direction. Then, for the upward translation, you would have to move 5 units upward and this is done by just adding five to the end of it.
