Answer:
2
Step-by-step explanation:
If we evaluate (-5y + 4) + (7y - 9), we get 2y - 5.
Therefore, N must equal 2.
<span>(–6, 43) is the solution
</span><span>y = -6x +7
43 = -6(-6) + 7
43 = 36 + 7
43 = 43</span>
Answer:
No
Step-by-step explanation:
Let's define our 2 terms first.
2x³y
2xy²
We see here that one term has a x³y and the other has a xy² term. Since they are not the same, the 2 terms are <em>not</em> like terms.
Answer:
1042
Step-by-step explanation:
-38,-8,22,52
The common difference is 52 - 22 = 30
a_1 = -38
a_2 = -38 + 30
a_3 = -38 + 2 * 30
a_4 = -38 + 3 * 30 (notice that the common difference is multiplied by 1 less than the term number)
a_n = -38 + (n - 1)30 (since the term number is n, we multiply the common difference by n - 1)
a_n = -38 + 30(n - 1)
a_37 = -38 + 30(37 - 1)
a_37 = 1042
