The "standard form" of a 2nd order poly is y = ax^2 + bx + c. Therefore, your 2 + 3x + x^2 in "standard form" is y = x^2 + 3x + 2.
Answer:
y = -2x+16
Step-by-step explanation:
The line has a y intercept at 16 (This is where it crosses the y axis)
The slope is found by using
m = (y2-y1)/(x2-x1)
We have two point (0,16) and (8,0)
m = (0-16)/ (8-0)
= -16/8
= -2
We can use the slope intercept form of a line
y= mx+b where m is the slope and b is the y intercept
y = -2x+16
total that play football = 40
30 of them play basket ball
the missing number is 40 - 30 = 10
Here we have two right triangles. And in such case we have to use altitude rule which is
ratio of part of hypotenue and altitude= ratio of altitude and remaining part of hypotenuse
So we get
r/h =h/s
So the correct option is s .
