Answer:
You haven't provided expressions, so I can work out the problem for you. When we divide fractions, remember always "keep, switch, flip!" That's what we're gonna do here. We keep the 2/5, switch the sign to multiplication, and flip the 7/8 to 8/7. Therefore, we have 2/5*8/7. That gives us 16/35. Hope this helps!
Step-by-step explanation:
0.75-6= 5.25
1.5+5.25=6.75
0.75+1.5=2.25
2.25-5.25=3
hope thia is helpful for you
Answer:
D
Step-by-step explanation:
(Using the formula in my attachment)
x^2 − 6x + 19
(x - 3)^2 = x^2 - 6x + 9
9 - e = 19
e = -10
(x - 3)^2 - e
(x - 3)^2 - - 10
(x - 3)^2 + 10
when x - 3 = 0, x = 3
Subsitute 3 into the equation
(3 - 3)^2 + 10
0 + 10
Minimum (3,10) in this case f(3) = 10
