What is the equation?
The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
Here given equations are
[tex]6x+6=0\\5y+10=0[/tex]
Now, compare both of them
[tex]6x+6=5y+10\\\\6x-5y=10-6\\\\6x-5y=4\\\\6x=4+5y\\\\x=\frac{4}{6}+\frac{5y}{6}\\\\x=\frac{2}{3}+\frac{5y}{6}\\\\[/tex]
When, [tex]y=0[/tex]
[tex]x=\frac{2}{3}[/tex]
Now when [tex]x=\frac{2}{3}[/tex], then
[tex]\frac{2}{3}=\frac{2}{3}+\frac{5y}{6}\\\\\frac{5y}{6}=0\\\\y=0[/tex]
Put [tex]x=\frac{2}{3},y=0[/tex] in the given equation
[tex]6x+6=6(\frac{2}{3})+6\\\\=2(2)+6\\\\=4+6\\\\=10[/tex]

2.state the measure of angle 5 and how you know
Thank you!
Answer:
1. No, Joe is not correct
2. [tex]\angle 5=72^{\circ}[/tex]
Step-by-step explanation:
Given: b and c are parallel lines

What's the eleventh term of a sequence with an explicit rule of ƒ(n) = 2 + 3(n – 1)?
Question 16 options:
A)
ƒ(11) = –31
B)
ƒ(11) = 32
C)
ƒ(11) = 23
D)
ƒ(11) = –22
Answer:
B. F(11) = 32
Step-by-step explanation:
From the explicit equation,
F(n) = 2 + 3(n - 1)
F(11) = 2 + 3(11 - 1)
F(11) = 2 + 33 - 3
F(11) = 35 - 3
F(11) = 32
The 11th term of the sequence with an explicit rule is 32

How many anagrams can you form with the word ESTADÍSTICA?
1,852,538
956,325
O2,494,800
35,198,000
879,100
Answer:
The number of anagrams of the word ESTADÍSTICA is 2,494,800
Step-by-step explanation:
Here we have ESTADÍSTICA which has 11 letters
2 As, 2 Ss, 2Ts, 2 Is 1 E, 1 D, and 1 C which gives 11 factorial possible ways out of which 2! × 2! × 2! × 2! are repetitions
Hence we have;
[tex]\frac{11!}{2! \times 2! \times 2! \times 2!} = 2494800[/tex]
Therefore, there are 2,494,800 anagrams of the word ESTADÍSTICA.
Answer:
They are 2,494,800 anagram in the word ESTADISTICA
Step-by-step explanation:
To find how many anagram that can be made from the word "ESTADISTICA" means to find how many possible ways the word can be arranged.
STEP 1: The word "ESTADISTICA" has 11 letter in it therefore it has 11!
STEP 2: They are some letter that occurs twice in the word "ESTADISTICA". Which are letter S, T, A, and I. The letters that occurs twice be represented as the denominator as 2!.
Therefore we have 2! × 2! × 2! × 2!
STEP3 : The number of anagram that can be formed with the word ESTADISTICA is
11! ÷ (2! ×2! × 2! × 2!)
11! = 11 × 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 = 39916800
(2! ×2! × 2! × 2!) = (2×1) × (2×1) × (2×1) × (2×1) = 16
Therefore;
39916800 ÷ 16 = 2494800
The word ESTADISTICA can form 2494800 anagrams. In other words it can be rearranged in 2494800 ways.

Answer:
y+6 = 7/3(x-1)
Step-by-step explanation:
The point slope form of the equation is
y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line
y - -6 = 7/3( x -1)
y+6 = 7/3(x-1)
Answer:
D
Step-by-step explanation:
The general form of a line in point-slope form is y-k=m(x-h), where k is the y coordinate any point on the line, h is the x coordinate, and m is the slope of the line. Therefore, the equation of this line would be y+6=7/3(x-1), or choice D. Hope this helps!
A local diner purchased a jukebox for 9400. The business makes a down payment of 1000 and agrees to pay 36 payments of 275 per month find the finance charge.
Answer:
Finance charge = $1500
Step-by-step explanation:
Cost price of jukebox = $9400
Down payment made by a local diner = $1000
Balance amount to be paid = 9400 - 1000 = $8400
In order to pay the balance amount diner agreed upon the installments = $275 per month for 36 months
Total amount to be paid in 36 months = 275 × 36 = $9900
So extra payment done = Total balance amount - Amount paid in 36 installments
= 9900 - 8400
= $1500
Therefore, finance charge paid by the diner was $1500.

what are the solutions of 2x^2 +16+34=0?
Answer:
5i, and - 5i ⇒ ± 5i
Step-by-step explanation:
We are given the equation 2x^2 + 16 + 34 = 0;
2x^2 + 16 + 34 = 0 ⇒ subtract ( 16 + 34 ) from either side of equation,
2x^2 = - 50 ⇒ divide either side by 2,
x^2 = - 25 ⇒ take square root on either side of equation,
| x | = √ - 25 ⇒ apply imaginary value i,
± 5i, provided absolute value sign | |;
Solution; ± 5i
PLS HELP I NEED IT RN WILL MARK THE BRAINLIEST PLSLSPSophie invests a total of $4500 in two separate accounts. One account pays 4% interest per year and the other one pays 4.75% per year. If the total interest earned at the end of one year is $202.50, how much money did she invest in each account?
Answer:
4% account - $1500
4.75% account - $3000
Step-by-step explanation:
x = amount of money in the account that pays 4% interest
y = amount of money in the account that pays 4.75% interest
x + y = 4500
0.04x + 0.0475y = 202.50
4x + 4y = 18000
4x + 4.75y = 20250
4x + 4y = 18000
- (4x + 4.75y = 20250)
= -0.75y = -2250
y = 3000
x + 3000 = 4500
x = 1500

Answer:
C. [tex]132m^3[/tex]
Step-by-step explanation:
Height = 4
Length = 6
Breadth = 7
Note : We were asked to find volume of the cuboid
Since, it has a base in the shape of a right angle triangle , we need to find the Area of the trapezium before calculating the total volume.
Step 1
Find the area of the trapezium
Area of a trapezium = [tex]\frac{1}{2} (a+b)h[/tex]
[tex]\frac{1}{2} (4+7)*4[/tex]
[tex]\frac{1}{2} (11)4\\[/tex]
[tex]\frac{1}{2} *44\\= 22[/tex]
Step 2
Calculate the volume of the cuboid
Volume of a cuboid =length× breadth × height
In this case , the volume will be our length × Area of a trapezium
V= 6 × 22
V = [tex]132m^3[/tex]

due, but the final payment is much larger than the regular mortgage
payments and is due at one time?
A. Hybrid ARM
B. Balloon payment
C. ARM
D. Balloon mortgage
Answer: Balloon Mortgage
Answer: Balloon Mortgage
Step-by-step explanation:
The type of mortgage described in the question is a "Balloon Mortgage." Option D.
What is a balloon mortgage?A balloon mortgage is a loan with regular mortgage payments over a set period, typically ranging from 5 to 7 years, but at the end of this term, the remaining balance (the "balloon" payment) becomes due in one large installment.
This final payment is significantly larger than the regular mortgage payments made throughout the loan term. Borrowers often use this type of mortgage when they expect to refinance or sell the property before the balloon payment is due.
