Rewrite 2x^2+x=15 as <span>2x^2+ x - 15 = 0. Use your favorite method to solve this for x. I prefer synthetic div., so will check out whether or not 2 is a root:
____________
2 / 2 1 -15
4 10
---------------------
2 5 -5 Since there is a non-zero remainder, 2 is NOT a root. Eliminate the 3rd answer choice.
Try -3. If used as a divisor in synth. div., will the remainder be zero or not zero? If zero, then -3 is a solution / root.
And so on.</span>
This is an arithmetic sequence.
The numbers differ by a constant.
The general form of an arithmetic sequence is:

Where
a is first term
n is nth term
d is the common difference
Looking at the sequence, we can say the common difference is -3 [since 3 is subtracted from a term to get the next term]
Also, first term is 13
Now, we plug into formula:

Answer:its values of y
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
since the line is parallel, it will have the same gradient. from this, we can deduce that tbe equation will also start with y = ⅕x.
next, we see that it passes through the point (0,6). what this means is, when x = 0, y = 6 which is better known as the y intercept. so in the form y= mx + b:
the equation of the line is y = ⅕x + 6
