Answer:
<h2>y = 3x + 3</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept
The formula of a slope:
==============================================
From the table we have :
x = 1 → y = 6
x = 2 → y = 9
x = 3 → y = 12
x = 4 → y = 15
Calculate the slope (choice any two pairs, and calculate the slope):
(1, 6), (2, 9)
We have the equation:
Put the coordinates of the point (1, 6) to the equation, and solve it for b:
<em>subtract 3 from both sides</em>
Finally:
Written in slope intercept it would be..
y= -2x^2 + 2x + 18
Get the denominator down to a one
15 ÷ 10
__
10 ÷ 10.
the unit rate is 1.5 / 1
the multipy to get the right denominator.
1.5 × 120 = 180
_________ ____
1 × 120 = 120
1.5. 15. 180. 135. 45
___ ____ ___ ____ ____
1. 10. 120. 90. 30
Answer:
420
Step-by-step explanation:
20 percent of 350 is 70, so adding that on will give us the price it is sold at for profit of 70 (20%).
Answer: 42
Step-by-step explanation: 35 divided by 5=7 so 35+7=42
