Answer:
4(4x-3)=63
X=4.6875
Step-by-step explanation:
Answer:
(- 3, 1 )
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y - 1 = 2(x + 3) ← is in point- slope form
with (a, b) = (- 3, 1 )
<em><u>Question:</u></em>
An Internet business charges a flat rate of $6.50 for shipping. If x represents the cost of the items purchased and y represents the total cost with shipping, which equation best represents the relationship between x and y?
<em><u>Answer:</u></em>
y = 6.5 + x represents the relationship between x and y
<em><u>Solution:</u></em>
Given that,
An internet charges a flat rate of $6.50 for shipping
Let "x" be the cost of items purchased
Let "y" be the total cost with shipping
Therefore,
Total cost with shipping = flat rate of 6.50 + cost of items purchased
Thus, we get,
y = 6.50 + x
y = 6.5 + x
Thus the above equation represents the relationship between x and y
15,000 - 2,500
=12,500 + 3,000
=15,500 - 1,000
=14,500 + 2,500
=17,000 - 3,000
=14,000 ft after 2 hours

Step-by-step explanation:
<u>Step 1: Define</u>
R(x) = 6x - 3
S(x) = -3x - 8
<u>Step 2: Find</u>
- Substitute in functions: R(x) - S(x) = 6x - 3 - (-3x - 8)
- [Distributive Property] Distribute negative: R(x) - S(x) = 6x - 3 + 3x + 8
- [Addition] Combine like terms: R(x) - S(x) = 9x + 5
