Consider the system of linear equations.
−4x+6y = 4
2x−3y = k
Determine the constant so that the system of linear equations has infinitely many solutions. (Hint: Graph the equations in the same coordinate plane. What should you see in order for the system to have infinitely many solutions?)
The value of the constant k such that the system has infinitely many solutions is; -2.
What is the value of k such that the system has infinitely many solutions?It follows from the task content that the system of equations given upon observation are multiples.
Hence, by multiplying the second equation by -2; we have;
-4x +6y = 4
-4x +6y = -2k
Hence, for the system to have infinitely many solutions; 4 = -2k.
Ultimately, k = -2 by dividing both sides of the equation above by -2.

A car dealership sells SUVs and passenger cars. For a recent year, 30 more SUVs were sold than passenger cars. If a total of 540 vehicles were sold, determine the number of each type of vehicle sold.
The number of each type of vehicle sold are :
SUVs : 300
Passenger cars : 270
Number of SUVs were sold more than passenger cars = 30
Total number of cars sold = 540
Let the number of Passenger car sold = x
Then, The number of SUVs sold = x + 30
So, Total number of cars sold = Number of Passenger car sold + Number of SUVs sold
540 = x + (x + 30)
2x + 30 = 540
2x = 540
x = 540/2
x = 270
We got, the number of Passenger car sold (x) = 270
The number of SUV's sold = x + 30
The number of SUV's sold = 270 + 30 = 300

Sachin can drive 110 more miles before he has to get gas.He has to drive 67 miles to his friends house and 32 miles to his moms.Use rounding to estimate whether he will have enough gas to go to both places
Rounding to an estimate, Sachin will have enough gas to go to both places before he runs out of gas.
What is an estimate?An estimate is an equivalent numerical value obtained by rounding off.
The result of an estimate is not an exact value. The value represents the nearest rounded value.
For instance, 75.9% can be estimated or rounded off to 76%. 32 minutes can be rounded off or approximated to ¹/₂ hour.
Data and Calculations:Driving distance before getting gas = 110 miles
The distance to his friend's house = 67 miles
The distance to his mom's house = 32 miles
The total distance to be covered on the available gas = 99 miles
Estimated distance to be covered = < 100 miles
Thus, using estimation, Sachin will still have more than 10 miles to drive before he gets gas.

The expression of f(x) = -2x² - 10 which is h(x) = -2x² - 6 would be vertically upward by 3 units, it becomes the graph of a function for f(x).
What is a function?The function is defined as a mathematical expression that defines a relationship between one variable and another variable.
The function h is defined as follows.
h(x) = -2x² - 6
If the graph of his translated vertically upward by 3 units, it becomes the graph of a function for f(x)
To determine the expression for f(x).
Vertical shifting of a graph is done by adding any arbitrary constant to the function in shifting.
For example, If shift up by 1 unit, add 1 to the function
If shift down by 4 units, subtract 4 from the function
Here h + 4 because adding 2 to the h coordinate would shift it up 2
⇒ h(f(x)) = ( x, y +4 )
⇒ f(x) + 4 = -2x² - 6
⇒ f(x) = -2x² - 6 -4
⇒ f(x) = -2x² - 10
Hence, the expression of f(x) = -2x² - 10 which is h(x) = -2x² - 6 would be vertically upward by 3 units, it becomes the graph of a function for f(x).

What is the equation?
Answer:
Answer = (2)n+(2)
Step-by-step explanation:
As the first step try to examine the distribution on both sides carefully.And as a general rule of thumb, try calculating the difference between 2 consecutive terms on "OUT" side. (if the difference is the same for every 2 consecutive terms, then the distribution is arithmetic)In this case it is (-4) - (-2) = -2.After that, try writing the first OUT term in terms of both that difference (most of the time difference comes in multiplication with n) and the first term on IN side.If that cannot be achieved in one go, then either add or subtract a suitable amount of value. it is as follows,first difference = -2
Now, -2 = -2 × (n) + (0) if n = 1
or -2 = -2 × (n) + (-6) if n = -2
or -2 = |-2| ×(n) + 2 :::: -2 = 2n +2 if n = -2
Now all the 3 arrangements are okay but except for the third one, others do not comply with higher terms in the distribution.Therefore, the third one turns out to be the correct arrangement.2. What does it mean if P(-4) for the polynomial function P(x) = x3 + 11x²
+34x + 24 equals zero?
Answer:
It means that the -4 is one of the solutions for this polynomial. In other words, -4 is a point in the x axis of the graph where the function touches said axis.
The value of the polynomial at P(-4) will be 0.
What is a polynomial?A polynomial in mathematics is an expression made up of coefficients and indeterminates and involves only the operations of multiplication, addition, subtraction, and non-negative integer exponentiation of variables.
Given that the polynomial function is P(x) = x³ + 11x² + 34x + 24. The value of the function at P(-4) will be calculated as:-
P(x) = x³ + 11x² + 34x + 24
P(-4) = (-4)³ + 11(-4)² + 34(-4) + 24
P(-4) = -64 + 176 - 136 + 24

Find the smallest number by which 6300 must be multiplied to make it a perfect
square.
To get a perfect square, the smallest number to be multiplied by 6300 is 7.
Multiplication is the process of calculating the result when a number is taken times. Each of the numbers is referred to as a factor of the product, which is the outcome of a multiplication.
Consider the number 6300 which can also be written as:
6300 = 2 × 2 × 3 × 3 × 5 × 5 × 7
Now, 2, 3, and 5 are in pairs. Only 7 is not in pair.
Now, we will multiply 6300 by 7.
Then,
6300 × 7 = 44100
Therefore, the number 44100 is the number that makes the perfect square.
Let's say x² = 44100,
Taking square root on each side of the equation:
x² = 44100
√x² = √44100
x = √[ 21 × 21 × 10 × 10 ]
x = 210
Therefore the smallest number by which 6300 is multiplied to get a perfect square is 7.
