Both a and b are functions. for it to be a function, you can only have 1 y value per x value.
this is not a function because 1 has 2 y values
(1,3)(2,5)(1,4)(3,2)
Answer:
The System of equation is .
Step-by-step explanation:
Given:
Let 'x' be the number of questions worth 5 points.
Let 'y' be the number of questions worth 2 points
Total Number of Problems = 29
So the Total Number of Problems is equal to sum of the number of questions worth 5 points and the number of questions worth 2 points.
Framing in equation form we get;
.
Also Given:
Test is of Total Points = 100
Now Total points in test is equal to sum of the number of questions worth 5 points multiplied by and the number of questions worth 2 points multiplied by 2.
Framing in equation form we get;
Hence The System of Equations are .
Answer:
Step-by-step explanation:
So since 9 is your radius because this is half a circle you want to use the equation piR^2 which is pi9^2, by solving this equation you end up with 254.34, which is the area of the semi-circle, now you need to find the area of the box but to solve this you would need the length and width and multiply them together to get the area of the box then subtract that by the area of the semi-circle and you get the shaded region
Answer:
1920
Step-by-step explanation:
What we can do is split this into two sections: the volume of the rectangle and the volume of the square.
Rectangle: We can follow the equation V = lbh, so we have 14x8x10, giving us 1120.
Square: We can use the same equation, V = lbh, giving us 10x10x8 which is 800.
Final Answer: To get the full volume, we have to add these together, so, 1120 + 800 = 1920.
