What would you use to represent the solution in an equation with a variable?
I would use the real line that goes from x belongs (-infinite, infinite).
What would you use to represent the solution in an equation with three variables?
To present the solution of an equation with three variables you need the XYZ coordinate system because you would generate a 3D graph because "because the number of variables is equal to the number of dimensions needed to graph the solution correctly".
Could you graph an equation that contains more than four variables?
It CAN NOT be done since the number of variables is equal to the number of dimensions that are needed to graph the solution correctly. Therefore, we can graph only up to three variables (three dimensions).
If you were given the graph of an equation with two variables in a coordinate plane, what would happen to the graph if all the values of y were increased by 1?
if all the values of y are increased by 1, the graph shifts by 1 unit to the right.
What would happen to the graph if all values of x were increased by 1?
If all values of x are increased by 1, the graph moves 1 unit up.
What would happen to the graph if all the <span> y-</span>values were multiplied by 2 or by 1/2?
If the values of y are multiplied by 1/2 then the slope of the graph is smaller so the graph looks wider.
If the values of y are multiplied by 2 then the slope of the graph is larger so the graph looks narrower.
Answer:
y=7x+5
Step-by-step explanation:
Answer:
- 2a² - 5a + 4ab - 2b + b²
Step-by-step explanation:
Distributing the parenthesis gives
= - 2a² - 2ab + 10a - 15a + 6b + 6ab + b² - 8b ( collect like terms )
= - 2a² + (10a - 15a) + (- 2ab + 6ab) + (6b - 8b) + b²
= - 2a² - 5a + 4ab - 2b + b²
------------------------------------------------------
coefficient of the a² term is - 2
coefficient of the ab term is + 4
coefficient of the b term is - 2
Answer: -47
Step-by-step explanation:
(−12)(6)+25
=−72+25
=−47
Answer:
11.2square feet
Step-by-step explanation:
Area of a sector = theta/360 * πr²
theta is the central angle = 80degrees
radius r = PC = 4ft
Substitute
Area of the sector = 80/360 * 3.14 * 4²
Area of the sector = 80/360 * 3.14 * 16
Area of the sector = 4,019.2/360
Area of the sector = 11.2ft²
Hence tthe area of the blue sector is 11.2square feet
