Answer:
(6x - 7y)(6x + 7y)
Step-by-step explanation:
36x² - 49y² ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , then
36x² - 49y²
= (6x)² - (7y)²
= (6x - 7y)(6x + 7y)
Answer:
(6x + 7y)(6x - 7y)
Step-by-step explanation:
36x² - 49y²
= (6x)² - (7y)²
= (6x + 7y)(6x - 7y)
In this question we used the identity-
a² - b² = (a + b)(a - b)

X = 10

X + Y = 17
X - Y = 3
The two numbers are 7 and 10 whose sum is 17 and whose difference is 3.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that the sum of two numbers is 17 and the difference of those same two numbers is 3.
We need to find those two numbers.
Let x and y are the two numbers.
Sum of two numbers is 17
x+y=17..(1)
Difference of two numbers is 3
x-y=3..(2)
From equation 1,
x=17-y
Now substitute this in equation 2.
17-y-y=3
17-2y=3
17-3=2y
14=2y
Divide both sides by 2
y=7
Now add y value in equation 1
x+7=17
Subtract 7 from both sides
x=10
Hence, the two numbers are 7 and 10.

Although being a military defeat, the Tet Offensive was a stunning propaganda win for communists. In fact, it is frequently regarded for changing the tide of the war in their favour.
As Viet Cong rebels invaded rural areas previously held by the South Vietnamese government, the South Vietnamese began to lose authority.
Despite tremendous deaths, North Vietnam secured a strategic triumph with the Tet Offensive, which represented a watershed moment in the Vietnam War and the start of the protracted, agonising American withdrawal from the region.

Solve the system of equations using subtraction. 2x-4y= -12 2x+y=8 plz help
Answers
Answer:
x=2, y= 4
Step-by-step explanation:
Equation 1 is 2x-4y = -12
Equation 2 is 2x+y = 8
Subtracting the two equations gives -4y-y = -12-8 (The 2x and the other 2x cancel each other out).
Simplifying we get -5y = -20 and y =4
Substituting y =4 into original equation back we get 2x -4(4) =-12
This equals 2x -16 =-12 and 2x = 4 and x =2

D.

Answers
The situation can be modeled by an exponential decay function with a percent change of -10%, option A is correct.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
The ratio between the value after 1 year and the value after 0 years is 18,000/20,000 = 0.9.
The ratio between the value after 2 years and the value after 1 year is 16,200/18,000 = 0.9.
The ratio between the value after 3 years and the value after 2 years is 14,580/16,200 = 0.9.
Since the ratio between consecutive values is constant and less than 1, we can conclude that the situation can be modeled by an exponential decay function.
r = (18,000/20,000) - 1 = -0.1
So the percent change per year is -10%, which means that statement A is true.
Hence, the situation can be modeled by an exponential decay function with a percent change of -10%, option A is correct.

You decide to buy a car with a base price of $11,499 at an interest rate of 6.2%. The car will be compounded monthly in those 5 years. What will your monthly payment be? Round the money to the nearest hundredth
Answers
Answer:
A = $15,696.72
Step-by-step explanation:
Use the compound amount formula: A = P(1 + r/n)^(nt). Here the number of compounding periods is nt, or (12 per year)(5 years) = 60.
Our formula becomes A = $11,499(1 + 0.062/12)^60, which works out to:
A = $11,499(1 + 0.0052)^60, or
A = $15,696.72
The monthly payment is $15,696.72/60, or $261.61.

When the winning score in golf is the lowest number, the lowest number is -1.
The value of the expression -273 - (-576) will be:
= -273 - (-576)
= -273 + 576
= 303
Also, -56/4 = -14. The value of the expression (2 - 19) + (-12) will be:
= (2 - 19) + (-12)
= -17 - 12
= -29
The value of -2x = 22 will be:
-2x = 22
Divide both side by -2
-2x/-2 = 22/-2
x = -11
The value of 5 + 3x = -22 will be;
5 + 3x = -22
5x = - 22 - 5
3x = -27
x = -27/3 = -9
5(x + 3) = 35
5x + 15 = 35
5x = 35 - 15

The equation of the scatter plot trend line is y = -1700x + 32000 where y is the value of the car in dollars and x is the age of cars in years. Use the trend line equation to predict the value of a car after 7 years.
Answers
Answer:
20100
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Given equation
y = -1700x + 32000
Where x is the age of car and y is the value of the car.
Then value after 7 years can be calculated as follows,
y = -1700 (7) + 32000
y = -11900 + 32000
y = 20,100
So, the value of car after 7 years will be 20100.
