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
Write an explicit formula for an, the nth term of the sequence 4, 20,100. WILL GET BRAINLIEST!!!!!
Answer:
aₙ = 4(5)ⁿ⁻¹
Explanation:
To identify a geometric series: second term = √(first term * third term)
Here given:
1st term: 42nd term: 203rd term: 100check ============
20 = √(100*4)
20 = √400
20 = 20 Hence its a geometric term.
Find common difference (r):
20/4 = 5 or 100/20 = 5
Geometric term formula:
aₙ = a₁(r)ⁿ⁻¹ [where a1 is the 1st term, r is common difference]
insert values found
aₙ = 4(5)ⁿ⁻¹ ......this is the nth term.

Based on the information provided in the table, the train appears to go the same distance each minute.
Does the train go the same distance each minute?
In order to determine if the train travels the same distance each minute, the average speed of the train has to be determined. Average speed is the total distance travelled per time.
Average speed = total distance / total time
Average speed when distance is 12km = 12 km /2 = 6km/hrAverage speed when distance is 24km = 24 km /6 = 6km/hrAverage speed when distance is 42km = 42 km /7 = 6km/hrTo learn more about average speed, please check: https://brainly.com/question/21734785

She uses 7 feet of it for a craft project and gives 28 inches of it to her sister.
How many inches of ribbon does she have left?
Enter your answer in the box.
Answer:
32 inches

Find the zero of the linear equation f(X)=2 by graphing
Answer:
Slope: 0
Y-intercept: (0,2)
Step-by-step explanation:
What is the measure of angle 1?
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.

How do credit scores in your county compare to those of your state and the nation?
Answer:
75/76 can easily be compared to my surrounding counties
Step-by-step explanation:
Southern states had lower average credit scores than the rest of the country, despite all states experiencing a boost (between 3 and ten points) in credit scores compared to 2019. Here are the top 10 states with the lowest credit scores in 2020: Mississippi: 675. Louisiana: 684.
By knowing this, I can create a ratio of 675/684. This can then simplify to

The value of a house has been increased by 7%
The newly valued price is £749000
What is the price before the increase
Answer:
700000
Step-by-step explanation:
If it has been increased by 7%, then its percentage would be 107% and the price before the increase [original price] would be 100%.
107%=749000
100%=x
where x is the new price.
Cross multiplying;
107x=749000
x=749000/107
x is 700000
Solve and classify the given system of linear equations.
p=5(q+2)
p=q-3
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

π^2 x ___ =
Answer:
1/π²
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.

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?
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.

?
O x = -9, x = 2
O x = -9, x = 0
Ox= -2, x = 9
O x=0, x= 9
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
