Answer:
F = 75.2
Step-by-step explanation:
Plug C into the equation, so-
24 = 5/9(f-32)
Then divide 5/9 from both sides-
43.2 = f - 32
Then add 32 to both sides
F = 75.2
The answer is D cuz that makes a straight line
Answer:
(4x+1)= 81
Step-by-step explanation:
4x+1= 81
4x= 81 - 1
4x= 80
x= 80/4
x= 20
Answer:
16
Step-by-step explanation:
i got it right on the test
First of all to transfer <span>(2x - 1)(x + 6) = 0 into a form where we can plug it into the quadratic formula we need to use the FOIL method.
</span><span>(2x - 1)(x + 6) = 0
</span> becomes
2x*x+2x*6+-1*x+-1*6
which simplifies to
2x^2 + 12x - x - 6
and then we add like terms to get
2x^2 + 11x - <span>6
</span>
now that it is in the correct form we can identify "a" "b" and "c" by following this form
ax^2 + bx + c
looking back at the equation we got earlier
2x^2 + 11x - <span>6</span>
a=2,b=11,and c=-6
