I think the value of x is 15
Answer:

Step-by-step explanation:
Students are asked to write
in the standard form.
Now, in the standard form of a polynomial the highest power of the variable takes the leftmost position and the lowest power of the variable takes the rightmost position and the power of variable decreases from left to right.
Therefore, the standard form will be
. (Answer)
The slope is the number with the letter x
The slope would be -10
The y intercept is the number at the end of the equation.
The y intercept is 1
D. (y-3)
I'm assuming that they want you to find the factors of the quadratic expression, which are (y-5)(y-3). (y-5) isn't up there, so (y-3) is the only solution that's really possible.
6.5 x 10 to the 3rd power
remember the base must be less than 10 and greather or equal to 1
