Answer:
D
Step-by-step explanation:
given the 2 equations
x + 2y = 27 → (1)
2x + 3y = 46 → (2)
Rearrange (1) expressing x in terms of y by subtracting 2y from both sides
x = 27 - 2y ← substitute into (2)
2(27 - 2y) + 3y = 46
54 - 4y + 3y = 46
54 - y = 46 ( subtract 54 from both sides )
- y = - 8 ( multiply both sides by - 1 )
y = 8 → D
Answer:
C
Step-by-step explanation:
We want to determine the vertex of the quadratic equation:

Recall that the vertex is given by the formulas:

In this case, <em>a</em> = -1, <em>b</em> = 2, and <em>c</em> = 1.
Determine the <em>x-</em>coordinate of the vertex:

To determine the <em>y-</em>coordinate, evaluate the function at <em>x</em> = 1:

In conclusion, the vertex of the quadratic equation is (1, 2).
Hence, our answer is C.

A quotient of a number and 6
Explanation: Quotient means that you divide something by another. Let's let n be the "number". Therefore, "a quotient of a number and 6" refers to n6 or n÷6 .
