Answer:
The table is a quadratic function
Step-by-step explanation:
Given
The attached table
Required
Tell if it is a quadratic function
The difference in the x values are uniform (i.e. difference of 1), so the following method can be applied.
(1) Subtract adjacent y values.




(2) Subtract adjacent differences in (1) above



Notice the calculated differences in (2) are the same.
<em>Hence, the table is a quadratic function</em>
Answer:
y=10x+99
Step-by-step explanation:
Find the negative reciprocal of the slope of the original line and use the point-slope formula y−y1=m(x−x1) to find the line perpendicular to x+10y=60.
Answer:
1/2
Step-by-step explanation:
The formula for slope is (y2 - y1)/(x2-x1)
In this case, it is (2 - 1/2)/(4-1) which is 1.5 over 3. The slope is 1/2
Answer:
150
Step-by-step explanation:
Each interior angle in a polygon is (n-2)×180 ÷n
(12-2)×180/12

Answer:
x=8, y=4
Step-by-step explanation:
7x + 10y = 96
5(5x - 2y = 32)
7x + 10y = 96
25x - 10y = 160
32x = 256
x = 8
7(8) + 10y = 96
56 + 10y = 96
10y = 40
y = 4
