Answer:
It would be 8
Step-by-step explanation:
Answer:
<em>( - 1 , - 4 ) </em>
Step-by-step explanation:
y = 3x - 1
y = x - 3
3x - 1 = x - 3 ⇒ <u><em>x = - 1</em></u>
y = 3( - 1 ) - 1 = - 4
<u><em>y = - 4</em></u>
<em>( - 1 , - 4 )</em>
Answer:
none of the above
Step-by-step explanation:
The largest square must be the first in the polynomial. Because 10-n, 5n+3n^3-1, and n+4n^2-7n^3 do not follow that rule, the answer must be none of the above.
Answer:
Step-by-step explanation:
z score= x - mean/standard deviation
1.20= x -100/15
18= x -100
118=x
z score= x - mean/standard deviation
0.5=x-73/4
2=x-73
75= x
If y is 5 when x is 2.5 and y varies directly with x, find y when x is 10.
The term "y varies directly with x" means that the formula is a direct variation. We need to look for the constant of variation.
y = kx ; where k is the constant of variation.
k = y/x
k = 5/2.5
k = 2
We then use the direct variation formula to get the value of y when x is a certain number.
y = kx
y = 2 * 10
y = 20
