The correct answer is 702.
Substitution method
y = x + 3 (*)
y = 3x + 1 (**)
Substitute (*) to (**):
3x + 1 = x + 3 <em>subtract 1 from both sides</em>
3x = x + 2 <em>subtract x from both sides</em>
2x = 2 <em>divide both sides by 2</em>
<h3>x = 1</h3>
Put the value of x to (*):
y = 1 + 3
<h3>y = 4</h3><h3>Answer: x = 1 and y = 4 → (1, 4).</h3>

Answer:
1,953,125
Step-by-step explanation:
The first term is a1 = 5; the common ratio is r = -25/5 = -5. The generic term is ...
an = a1×r^(n-1)
an = 5×(-5)^(n-1)
So, the 9th term is ...
a9 = 5×(-5)^(9-1) = 1,953,125
Answer:
Yes
Step-by-step explanation:
The answer is proportional because the variables correspond directly to each other.
1=225
2=450
3=675
4=900
Answer:
3/12
Step-by-step explanation:
The slope is Rise over Run
They gave you the rise of 12ft
and a horizontal change is equal to run which is 100.
12/100 simplifies to 3/12.
Hope this helps.
