Answer:
17.25
Step-by-step explanation:
You already know y = 72, so you could rewrite the equation to 72 = 4x + 3. To get to the answer, you need to find what X is. What you should do is subtract 3 from both sides, get 69, divide by 4 on both sides and get 17.25
I'm not sure if this is correct, but I hope this helped.
Answer:
1.5y - 5
Step-by-step explanation:
I used the distributive approach and distributed -1/2 to the -3y and 10.
(If you try this and it's incorrect, you may just need to distribute -1/2 to the 10, creating -3y - 5.)
From the graph we can observe the following characteristics:
a) The graph is rising towards the left and falling towards the right. Since the two ends of the graph are in opposite direction, the degree of the polynomial which is represented by the graph will be odd. In case of even degree, the both ends face the same direction.
b) The coefficient of the polynomial must be negative. Only in this case the graph will fall towards right and rise towards left. In case of a positive coefficient, the graph falls towards left and rise towards right.
So, the polynomial represented by above graph will have negative coefficient and odd degree, which is represented by option C.
So, the answer to this question is C
If you're trying to solve for x, you need to use the quadratic formula.
Plug in the numbers from the standard form of a quadratic equation
(which is
)
From here, this solves down to
Take the square root of 196, which is 14
Now, you can solve for both the + and - variations on the equation.
The solutions to your equation are 1.5 and 5/8 (probably)
