Answer:
The discriminant b2−4ac < 0, the equation has no real number solutions, it has complex solutions
Step-by-step explanation:
9x² - 4x + 1 = 0 ax² + bx + c = 0
The discriminant: b² - 4ac = (-4)² - 4*9*1 = 16 - 36 = -20
b2−4ac < 0, the equation has no real number solutions, it has complex solutions
m_3 is (7x-4)°
Step-by-step explanation:
which is that m_3 is(7x -4)°.
Answer:
See below.
Step-by-step explanation:
No, a reasonable estimate is around 7 * 6 = 42.
Round $6.99 to $7 and multiply by the 6 family members.
Answer:
She paid $29.29
Step-by-step explanation:
Finding 7% of 25
Y is 7% of 23.2
Solving our equation for Y
Y = P% * X
Y = 7% * 23.2
Converting percent to decimal:
p = 7%/100 = 0.07
Y = 0.07 * 23.2=1.624
Y ≅ 1.62
Finding 18% of 25
Y is 18% of 23.2
Solving our equation for Y
Y = P% * X
Y = 18% * 23.2
Converting percent to decimal:
p = 18%/100 = 0.18
Y = 0.18 * 23.2= 4.176
Y≅4.18
Add sales tax and tip to 25
25+4.18+1.62= 30.8
But since my answers were estimated to a different way, I would say it s best to say it is d.29.29
