Answer:
I’m pretty sure that it is D because it says boundary and not just where it is at.
Step-by-step explanation:
If you have an equation for your graph you would substitute the y AND x with 0, you the solve the solution and if the solution is true then the space where (0,0) is located becomes the shaded area because that resembles the area in which everything is a positive solution with the equation. If it is false then the opposite area is then shaded because (0,0) doesn’t work with the problem.
I hope you get it right! Have a good week :D
Answer:
The greatest value of the expression 1-x^2 is 1
Step-by-step explanation:
Here, we want to find the greatest value of the integer 1-x^2
We should understand that when we talk of integers, we are referring to whole numbers.
We should understand that 0 is also an integer.
Apart from zero, any other integer we substitute for x will give the function a negative value. Only 0 will make sure that the value remains positive and as such gives the function its highest possible value
So therefore;
1-0^2 = 1-0 = 1
Hence, the greatest possible value of the expression is 1
Answer:
Top row: 3,6,9,12,15
Bottom row: 5,10,15,20,25
Step-by-step explanation:
As ordered pairs/ratio form:
3:5, 6:10, 9:15, 12:20, 15:25
Let us say that:
x = hours worked by Wolfgang
y = hours worked by Heinrich
So that:
x = y + 10
14 x + 12 y = 3520
By combining the two equations:
14 (y + 10) + 12 y = 3520
14 y + 140 + 12 y = 3520
26 y = 3380
y = 130 hours
x = y + 10 = 140 hours
<span>So Wolfgang worked 140 hours while Heinrich worked 130
hours.</span>
