Fraction: 3/5
Step-by-step explanation:
Hope this helps!
Step-by-step.
30255.5=a90.75
Step 1: Cross-multiply.
30255.5=a90.75
(3025)*(90.75)=a*(5.5)
274518.75=5.5a
Step 2: Flip the equation.
5.5a=274518.75
Step 3: Divide both sides by 5.5.
5.5a5.5=274518.755.5
a=49912.5
Eight and a half is a whole number.
In a quadratic equation
q(x) = ax^2 + bx + c
The discriminant is = b^2 - 4ac
We have that discriminant = 3
If
b^2 - 4ac > 0, then the roots are real.
If
b^2 - 4ac < 0 then the roots are imaginary
<span>In
this problem b^2 - 4ac > 0 3 > 0 </span>
then
the two roots must be real
y < x; y > 5; x > 2
A. (9; 7) → x = 9; y = 7
y < x → 7 < 9 TRUE
y > 5 → 7 > 5 TRUE
x > 2 → 9 > 2 TRUE
B. (7; 5) → x = 7; y = 5
y > 5 → 5 > 5 FALSE
C. (-3; 8) → x = -3; y = 8
y < x → 8 < -3 FALSE
D. (3; 2) → x = 3; y = 2
y > 5 → 2 > 5 FALSE
E. (8; 6) → x = 8; y = 6
y < x → 6 < 8 TRUE
y > 5 → 6 > 5 TRUE
x > 2 → 8 > 2 TRUE
F. (6; 6) → x = 6; y= 6
y < x → 6 < 6 FALSE
Answer: A. (9; 7) and E. (8; 6)
