Answer:
1a. 1.5
1b. 0.38
Step-by-step explanation:
a.
one full grid is full (1) and half a grid is full (0.5)
b.
there are 100 squares and 38 of them are filled in,so you divide 38 by 100 which is 0.38
Answer:
Step-by-step explanation:
The points are (1, 3) and (-1, 1)
y2 = 1, y1 = 3, x2 = -1 and x1 = 1
Slope m = (y2 - y1)/(x2 - x1)
m = (1 - 3)/(-1 - 1)
m = -2/-2
m = 1
The question is
y - y1 = m(x - x1)
y - 3 = 1(x - 1)
y - 3 = x - 1
y = x - 1 + 3
y = x + 2

Answer:
Using the Quadratic Formula
x=-b ± √b²-4ac/[2a]
x= -(-5) ± √5² - 4(1)(5)/(2)
x= 5 ± √25-20 /(2)
x= 5 ± √5 /(2)
x= 5 + √5/(2) and 5 - √5/(2)
