O x = -9, x = 0

O x=0, x= 9
Answers
Answer:
3rd option
Step-by-step explanation:
the denominator cannot be zero as this would make the expression undefined.
equating the denominator to zero and solving gives the values that x cannot be.
x² - 7x - 18 = 0 ← in standard form
(x - 9)(x + 2) = 0 ← in factored form
equate each factor to zero and solve for x
x - 9 = 0 ⇒ x = 9
x + 2 = 0 ⇒ x = - 2
then
x = - 2, x = 9 ← are the excluded values

Step-by-step explanation:
On multiplying π² by its inverse value, you get the answer to be 1, which has no decimal points.
π² × 1/π² = 1Answer:
π² × 1/π² = 1
Step-by-step explanation:
Given equation,
→ π² × ___ = ?
Let's keep the missing term as y, and product as 1 (a number with no decimal).
→ π² × y = 1
Then the answer will be,
→ π² × y = 1
→ [ y = 1/π² ]
Verification of the value of y,
→ π² × y = 1
→ π² × (1/π²) = 1
→ [ 1 = 1 ]
→ LHS = RHS
Hence, 1/π² is the missing term that ends up with a number with no decimal.

Answers
Answer:
q = -3.25
p = -6.25
Step-by-step explanation:
substitute p with ( q-3)
q-3 = 5(q+2)
q-3 = 5q + 10
q-5q = 3+10
-4q = 13
q = -3.25
if q = -3.25 therefore
p= -3.25 -3

Step-by-step explanation:
120 divided by 12=10
The total number of the drummers Brady will see in the parade will be 180 and in each band there are 15 drummers.
What will be the number of drummers?We know that Brady went to a big parade and saw 12 different marching bands. If each band had an average of 120 members and 1/8 of them were drummers.
Here each band has 120 members.

The value of y is 3 if the value of x is 4 in the linear equation with two variables.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
Two linear equations in two variables x and y
x + y = 7
x = 4
Plug x = 4 in the equation x + y = 7, we get:
4 + y = 7
y = 7 - 4
y = 3
Thus, the value of y is 3 if the value of x is 4 in the linear equation with two variables.

mary has 3 blouses (red, black, and white), 2 pairs of pants (black and blue), and 4 pairs of shoes ( red, blue, black, and white). if mary picks each part of her outfit randomly, what is the probability that mary's outfit will be black bouse, black pants, black shoes?
Answers
The probability that Mary's outfit will be black blouse, black pants, black shoes is 1/24 if the Mary has 3 blouses, 2 pairs of pants, and 4 pairs of shoes.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.
We have:
Mary has 3 blouses (red, black, and white), 2 pairs of pants (black and blue), and 4 pairs of shoes (red, blue, black, and white).
P(black blouse) = 1/3
P(black pants) = 1/2
P(black shoes) = 1/4
Probability that Mary's outfit will be black blouse, black pants, black shoes:
= (1/3)(1/2)(1/4)
= 1/24
Thus, the probability that Mary's outfit will be black blouse, black pants, black shoes is 1/24 if the Mary has 3 blouses, 2 pairs of pants, and 4 pairs of shoes.

What is the measure of angle 1?
Answers
Answer:
27 degrees
Step-by-step explanation:
The easy way is by remembering the formula (a-b)/2=c, where a is the larger angle, and b is the smallest angle. (90-36)/2=27.
The longer, more drawn out answer goes as follows. See the image to understand the notation I use:
AOE + BOD + BOA + DOE = 360AOE + BOD = 90 + 36 = 126BOA + DOE = 360 - AOE - BOD = 234Since the sum of a triangle's angles is 180, ODE = (180 - DOE) / 2Likewise, OBA = (180 - BOA) / 2Since CDE is 180, CDO = 180 - ODE = 180 - (180 - DOE) / 2Likewise, CBA is 180, so CBO = 180 - OBA = 180 - (180 - BOA) / 2The interior angles of the irregular polygon CBOD add up to 360, so CBO + CDO + BOD + BCD = 360.Substituting what we already found, 180 - (180 - BOA)/2 + 180 - (180 - DOE)/2 + 36 + BCD = 360Cleaning it all up, we get 180 + (BOA + DOE)/2 + 36 + BCD = 360As we found in line 3, BOA + DOE = 234, so substituting that in, 180 + 117 + 36 + BCD = 360Finally, solving for BCD (360 - 36 - 117 - 180) we get our answer, 27Note: The long drawn out method shown above is a way to derive the formula for the secant theorem. You do not need to use this method every time. Just remember, large angle minus small angle, all divided by 2. That is it.

8(2)=93+11y11y=16-9311y=-77y=-7Answer:
2, -7
Step-by-step explanation:
QuestionSolve the system of linear equations:
8x = 93 + 11y7x = -63 - 11y-------------------------------------------------------------------------------------
SolutionAdd the equations together to eliminate y:
8x = 93 + 11y
+ 7x = -63 - 11y
-------------------
15x = 30
⇒ x = 30 ÷ 15
⇒ x = 2
Now substitute the found value of x into one of the equations and solve for y:
⇒ 7x = -63 - 11y
⇒ 7(2) = -63 - 11y
⇒ 14 = -63 - 11y
⇒ 11y = -63 - 14
⇒ 11y = -77
⇒ y = -77 ÷ 11
⇒ y = -7
Therefore, x = 2 and y = -7
