Answer:
y = 360x+200
Step-by-step explanation:
We will use the concept of finding the equation of a line using two coordinates (x1,y1) and (x2,y2)
If after 3 months, ethan has 560 dollars in his savings, and after 6 months, he has 920 dollars, this can be represented as coordinate points (3,560) and (6,920)
The equation of a line in point slope form is expressed as;
y = mx+c
m is the slope = ∆y/∆x = 920-560/6-3
m = 360/3
m = 120
Get the intercept;
Substitute m = 120 and any of the points to get c, using the point (3,560)
x = 3, y = 560
560 = 120(3)+c
560 = 360+c
c = 560-360
c = 200
Get the required equation by substituting m and c into y = MX+c
y = 360x+200
Answer:
A. x > 1
Step-by-step explanation:
2x + 3 >= 7
2x >= 4
x >= 2
or
2x + 9 > 11
2x > 2
x > 1
Answer
x > 1
Answer:
Step-by-step explanation:
(9, 8) ⇒ x₁ = 9, y₁ = 8
(-3, 6) ⇒ x₂ = -3, y₂ = 6
So the slope:
Answer:
5
Step-by-step explanation:
$4.75 + 0.3x = $6.26
0.3x = 1.51
x = 5.033
