Answer:
Step-by-step explanation:
6) the answer is option b
y = - x + 3
x - y = 1
From the graph, the point at which the lines of the two equations meet is the solution to the system of equations
The points = x = 2 and y = 1
If you substitute these values in option b, it satisfies the equations.
7) the correct option is d
-x + y = -3 - - - - - - -1
2x -y = 6 - - - - - - 2
If we solve using elimination method,
Multiply equation 1 by 2 and equation 2 by 1
-2x + 2y = -6
2x -y = 6
Adding both equations
y = 0 and substituting y = 0 in equation 2,
x = 3
So y = 0 and x = 3
So it has only one solution
8) The lines of the two equations meet at a point where x = 3 and y = 0
Option d is the correct answer
-x +y = -3
2x - y = 6
Substituting x = 3 and y = 0 in option d,
- 3 + 0 = -3
6 - 0 = 6
9) y = x-2
x = 17-4y
Substituting y = x - 2 in x = 17 - 4y, we have
x = 17 -4(x - 2)
Opening the bracket
x = 17 - 4x + 8
x + 4x = 17 + 8
5x = 25
x = 25/5 = 5
Answer:
48
Step-by-step explanation:
area of a parrelogram formula:
A=bh
A=(8)(6)
A=48
The value f of x over g of x is 9x³ − 11x² − 7x. Then the correct option is C.
<h3>What is a function?</h3>
The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.
The two functions are given as
f(x) = 36x⁵ − 44x⁴ − 28x³ and g(x) = 4x²
We have to find the division of f(x) by g(x).
We can separate 4x² to each term of f(x). Then we have
Thus, the value f of x over g of x is 9x³ − 11x² − 7x. Then the correct option is C.
