Answer:
3/4
Step-by-step explanation:
-2-(-5) divided into 6-2
-2 +5 divided into 4
3 divided into 4
Answer:
y < x + 5
Step-by-step explanation:
Determine the equation of the broken line in slope- intercept form
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (- 5, 0) and (x₂, y₂ ) = (0, 5)
m = 
= 
= 1
note the line crosses the y- axis at (0, 5) ⇒ c = 5
y = x + 5 ← equation of broken line
Thus y < x + 5 is the inequality for the graph
put them together and add them up
Step-by-step explanation:
Given,
A linear function consisting of 2 terms, one is dependent on time and the other one is independent of time, i.e.,
A = -2.3t - 7
The dependent term -2.3 indicates that the altitude of Mr Mole decreases by 2.3 meters every minute.
At t = 0, A = -2.3(0) - 7 = 0 - 7 = -7. (Negative sign indicates the value is below the ground level of 0 meter.
The constant term - 7 is the altitude at t = 0, because at t = 0
Thus, Mr. Mole's burrow lie 7 meters below the ground.
