Answer:
y=5x+18
Step-by-step explanation:
The formula for point- slope is
y-y1= m(x-x1)
First substitute the values of the line from the question.
y-8=5(x+2)
Then solve for the slope- intercept form.
y-8=5(x+2)
y-8=5x+10
y=5x+18
Answer:
y=2x+5
Step-by-step explanation:
u find the slope and since the y intercept is (0,5), that's the b value
hope this helps
Answer:
48
Step-by-step explanation:
The weight of each small tables and chairs in the United States is 15lbs and 3.5lbs respectively.
<h3>Simultaneous equation</h3>
Let
- Weight of tables = x
- Weight of chairs = y
- Cost of 3 tables and 5 chairs is 62.5lbs
- Cost of 3 tables and 2 chairs is 52lbs
3x + 5y = 62.5
3x + 2y = 52
- Subtract the equation to eliminate x
5y - 2y = 62.5 - 52
3y = 10.5
y = 10.5/3
y = 3.5 lbs
Substitute y = 3.5 into
3x + 2y = 52
3x + 2(3.5) = 52
3x + 7 = 52
3x = 52 - 7
3x = 45
x = 45/3
x = 15 lbs
Therefore, the weight of each small tables and chairs in the United States is 15lbs and 3.5lbs respectively.
