Answer:
x = 1.56 or x = -2.56
Step-by-step explanation:
From the equation;
x2 +x − 4 = 0
a = 1 , b = 1, and c = -4
x = (-b ± √(b² -4ac))/2a
= (-1 ± √(1²- 4×1×-4))/2
= ( -1 ± √(17)/2
= (-1 ± 4.12)/2
= (-1 + 4.12)/2 or (-1 - 4.12)/2
<u>x = 1.56 or x = -2.56</u>
Answer:
(c) y-2 = -4(x-3)
Step-by-step explanation:
The point-slope equation of a line is ...
y -k = m(x -h) . . . . . . line through point (h, k) with slope m
For (h, k) = (3, 2), and m = -4, the equation of the line is ...
y -2 = -4(x -3)
Answer:
20
Step-by-step explanation:
To solve, I converted the fraction to decimals
1.5/(2.25-0.75) X 1.8 = 1.5/1.5 X 1.8 = 1.8
3.2 - 1.20 = 2
3(2/30 - 1/30) = 3(1/30) = 3/30 = 1/10 = 0.1
2(2/64 / 1/16) = 2(32/64) = 2 (1/2) = 1
1.8/0.1 + 2/1 = 18 + 2 = 20

Answer:
Slope=14.000/2.000=7.000
x-intercept = 300/-7 = -42.85714
y-intercept = 300/1 = 300.00000
