Answer:
see below
Step-by-step explanation: 5 20 15 28
3x + y = 23
3x – 2y = 8
O I should add, and the Xs will be eliminated. 3x + 3x = 6x NOT eliminated
O I should add, and the Ys will be eliminated. y + -2y = -y NOT eliminated
O I should subtract, and the Xs will be eliminated. 3x - 3x = 0x X is eliminated
O I should subtract, and the Ys will be eliminated. y - -2y = y NOT eliminated

Answer - A job that uses geometry and symmetry is an Architect.
---------------------------------------------------
Architect - geometry is structural and symmetry are shapes and figures that can be split and still look the same. Being an architect shows how geometric structures are transformed, then symmetry are design concepts throughout the plans of transformation.

Answer:
A
Step-by-step explanation:
Start with the 3.
You know that there is a difference of 4 between (say) 2 and 5. The 3 is a sign that the sequence is increasing. The members of the sequence are going up.
n - 1 means that the nth terms is calculated as an and uses the number of terms to be n-1. That means that the first term is a1 which is the starting point of the sequence.
The answer is an = a1 + (n-1)*d
d = 3
a1 = - 7
So let's try the formula out.
a4 = -7 + (4 - 1)*3
a4 = -7 + 3 * 3
a4 = -7 + 9
a4 = 2
Is 2 the 4th term in the series? Yes it is!
