Answer:
<h2>n>8</h2>
Step-by-step explanation:
Step one:
given data
needed amount= $80
the amount already saved= $8
earnings per hour= $9
let the number of hours worked be n
and let y represent the total
the situation represented linearly is
y=mn+c
Step two:
substituting our data to find n
9n+8>80
9n>80-8
9n>72
divide both sides by 9
n>72/9
n>8
Therefore he must work a minimum of 8houees
The answer for 4x10^2 would be 400
-3•4^x=-48
+3
-45=4^x
that's all I know
Answer:
At point C (-0.5,2)
At point E (1,5)
Step-by-step explanation:
The points that defines the linear quadratic equation system is as follows:
As we can see that the point E and Point C are the solutions set that have an intersections between the parabola i.e. blue and the red line also they are on the both curves at the same time. In addition to this, their coordinates satisfy the both equations in the similar time
Hence, the same is to be considered
Answer:
125 meter.
Step-by-step explanation:
After Reading the question we can draw the figure which is triangle XPS
given below.
The point S denotes the Surveyor who is at distance 200 from the south shore(P) and this point P is at y distance from North shore (X) and also the angle given is 32 degree.
So in triangle XPS right angled at P
