Answer:
C=45
if 9/11 = c/55 you have to divide the c/55 by 9/11, resulting in c/9 = 5
multiply 9 by 5 to get 45

Answer:
The trip took 22 hours
Step-by-step explanation:
1100 miles divided by 50 mph to find an hour which ended up as 22
<u>Part 1</u>
The gradient of the line is , so the equation is .
This means the system is
<u>Part 2</u>
Substituting in the coordinates (-3,11) and (2,1) into the equation of the parabola,
Subtracting the equations, we get 10=5a, and thus a = 2
Substituting a = 2 back into the system, we get b = -7
<u>Part 3</u>
The equation of the parabola is , and the turning point is at . Therefore, the value of y is -7
Answer:
The graph is attached below. Just google it "plot(2(3)^x)"
Answer:
x>-4
Step-by-step explanation:
-3x+5<17
subtract 5 from both sides
-3x<12
divide 3 from both sides
-x<4
divide by -1
x<-4
when dividing a negative number you flip the sign
x>-4
