The y-intercept is at 6.
The slope of the line is 2/3.
The answer is y = 2/3x + 6, so the 3rd option is correct.
Answer:
Step-by-step explanation:
a) 4x² + 20 = 0
4x² = -20
x² = -20/4
x² = -5 = i² *5
x = √i²5
x = i√5
b) 4x² + 5 = -7
4x² = -7 - 5
4x² = - 12
x² = -12/4
x² = -3 = 3i²
x = i√3
c) x² + 4x + 20 = 0
a = 1 ; b =4 ; c =20
= (-2 +4i) & -12/2
= (-2 + 4i) and (-6)
Answer:
14.39
Step-by-step explanation:
In math
"of" means times (x)
"is" means equals (=)
"a number" is your unknown which you can call anything but we'll call x
2/5 of a number is 14
Translation...
2/5 * x = 14
Divide each side by 2/5 to isolate x. To divide a fraction, multiply the reciprocal of the divisor (flip the numerator and denominator).
x = 14 * 5/2
x = 70/2
x = 35
2/5 of 35 is 14.
