Answer: y = 3.5 x+ 43.8
Step-by-step explanation:
Here x represents the number of years after 1990
Thus, we get the table that is used to find the equation will be,
x 0 2 4 6 8
y 45 51 57 61 75
Let the equation that shows the above data,
y = b + a x ---------(1)
By the above table,
By substituting these values in the above value of a and b,
We get b = 43.8 and a = 3.5
Substitute this value in equation (1)
we get, the equation that shows the given data is,
y = 3.5 x + 43.8
⇒ Option (3) is correct.

I got it wrong and it gave me the answer
Answer:
x = 9
Step-by-step explanation:
1/4(8x+12) =21
1/4 * 8x = 2x
1/4 * 12 = 3
2x + 3 = 21
21 - 3 = 18
2x = 18
18/2 = 9
x = 9
Answer:
Step-by-step explanation:
So since the question is no completed. The only way you can answer this is by simplifying it which is not the same as the value of x. It would be 3x+8
Subtract (10 divided into fifths) from (20 divided into half)
= (20 divided into half) - (10 divided into fifths)
= (20 / 2) - (10 / 5)
If you need to solve this expression expression:
= 10 - 2
= 8
I hope this helps you
