Answer:
50 marbles
Step-by-step explanation: The difference between the ratio of the red and green marbles is 4 units and the number value is 20 so its safe to say that 4 units is equal to 20 and thus one unit is 5 and because of the fact that there is a total of 10 units of marbles in the box according to the ratio, just multiply 5 and 10 which you get 50.
4 units = 20
1 unit = 20÷4 = 5
Total = 10 units
10 unit = 5 ×10 = 50
Ans : 50 marbles

after watching a two minute video on how to tell if a relation is a function, I can confidently tell you that the answers are 2, 3, & 4.

</h3>
answers 3 & 4 are the x and y coordinates of the points.
this relation is not a function because it does not pass the vertical line test.
( the vertical line test is where you look at all the vertical lines on the page and check if any of them have multiple dots on them. in this case, the line at x coordinate 1 has dots on both (1, 1) and (1, -1) )
Answer:
±1, ±2, and ±4
Step-by-step explanation:
4x² + bx + c = (Ax + B) (Cx + D)
Distribute:
4x² + bx + c = ACx² + (AD + BC) x + BD
Matching the coefficients, AC = 4. So A must be a factor of 4. Possible values of A are therefore ±1, ±2, and ±4.
