Answer:
B. A one-to-one relation between x and y
Step-by-step explanation:
16 3/4 + 12 3/4 =
3/4 + 3/4 = 6/4 =1 2/4 = 1 1/2
16 +12 = 28
28 + 1 1/2 = 29 1/2 hours
Answer:
-3, 5/2
Step-by-step explanation:
What are the roots of the function y = 4x2 + 2x – 30?
To find the roots of the function, set y = 0. The equation is 0 = 4x2 + 2x – 30.
Factor out the GCF of : 2, so the equation becomes 0 = 2(2x2+x-15)
Next, factor the trinomial completely. The equation becomes: 0=2(x+3)(2x-5)
Use the zero product property and set each factor equal to zero and solve.
x+3=0 2x-5 = 0
x = -3, 5/2
The roots of the function are -3, 5/2.
Hope this helped!
If you cross multiply and the answers are the same.
2/5=4/10 because 5*4=20, and 10*2=20
