Solve by grouping if you are able to find distinct factors that multiply to the last term and add to the middle term...this method is rather easy with easy to manage numbers. Complete the square if you cannot find distinct factors that multiply to the last term and add to the middle term. Completing the square helps when the equation is in the form of a parabola.
Answer:
Step-by-step explanation:
Please share the possible answer choices next time.
c = 10 + 3t is a linear function with y-intercept (0, 10) and slope 3.
Plot (0, 10). Starting there, move your pencil point 1 unit to the right and 3 units up. Plot this new point (1, 13). Draw a line connecting
(0, 10) and (1, 13).
Answer:
undefined
Step-by-step explanation:
We can find the slope of the line using
m = (y2-y1)/(x2-x1)
= (-2 - -10)/(-1 - -1)
= (-2+10)/(-1+1)
= 8/0
When we have a 0 in the denominator the slope is undefined
Answer:
x = 0 , -2 , 1 +i√3 ; 1 - i√3
Step-by-step explanation:
2x⁴ + 16x = 0
2x(x³ + 8) = 0
2x(x³ + 2³) = 0
2x (x + 2)(x² -2x + 2²) = 0 {a³ + b³ = (a + b)*(a² -ab +b²}
2x = 0
x = 0
x + 2 = 0
x = -2
x² - 2x + 4 = 0
a = 1 ; b = -2 and c = 4
D = b² - 4ac = (-2)² - 4*1*4= 4 - 16 = -12
root = (-b ± √D)/2a
= (-(-2) ± 2i√3)/2*1
= (2 ± 2i√2)/2
Answer:
n=14
Step-by-step explanation:
-6=(n/-14)-5
-6+5 = n/-14
-1= n/-14
cross multiplication and striking of negative sign from both side.
n=14
