Answer:
3) x-axis: 1 unit
y-axis: 10 units
4) quadrant II
coordinates: (-2, 4)
7) Quadrants I and IV; time is always positive , but temperature can be positive and negative
8) W = (-0.75, -1)
Step-by-step explanation:
3) x-axis: 1 unit
y-axis: 10 units
4) quadrant II
coordinates: (-2, 4)
7) Quadrants I and IV; time is always positive , but temperature can be positive and negative
8) W = (-0.75, -1)
The equation is:
20,000 * e^(0.15 t) = 28,000
e^( 0.15 t ) = 28,000 : 20,000
e^( 0.15 t ) = 1.4
0.15 t = ln 1.4
0.15 t = 0.3365
t = 0.3365 : 0.15
t = 2.24 ≈ 2
Answer:
A ) 2 years.
Answer:
y = 2x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2, so
y = 2x + c ← is the partial equation
To find c substitute (- 2, 3 ) into the partial equation
3 = - 4 + c ⇒ c = 3 + 4 = 7
y = 2x + 7 ← equation of line
Answer:
Yes
Step-by-step explanation:
s<30
Put in 28 for s
28<30
Twenty eight is less than 30 so it is a solution
