Answer:
x = 6
Step-by-step explanation:
5 (x - 3) + 2 = 5 (2x - 8) - 3
<em>remove the parenteses</em>
5x - 15 + 2 = 10x - 40 - 3
<h3><em>calculate</em></h3>
5x - 13 = 10x - 43
<h3><em>move the terms</em></h3>
5x - 10x = -43 + 13
<h3><em>collect like terms </em></h3><h3><em>calculate</em></h3>
-5x = -30
<h3><em>divide both sides</em></h3><h3><em /></h3>
Solution
x = 6
A:93
B: slope
the slope is the rate of change of the line.
this line models the distance between cop and the driver. note that the
cop is standing still while the sports car is moving away at 93 mph
if
the x-axis is in hours and the y-axis is in miles, then slope =
rise/run = km/h, which is kilometers per hour. the slope is the rate of
change of distance for the distance vs time graph
therefore the slope is 93 mph
Answer:
Step-by-step explanation:
First off, you need to add up AB and BC. You would get the equation:
2(3x-4)=62, since there are two segments. Solve it/simplfy.
6x-8=62 => 6x=70 => x= 11.66666(forever)
Since you alreday solved one, you easily know the answer is c.
No. -3=2(4)+1 simplifies down to -3=9 and that is not true
Answer:
We cannot infer at the 10% significance level that the assumption of ski centers is wrong
Step-by-step explanation:
The null hypothesis for this question can be stated as
Null hypothesis H0: =4
Alternate hypothesis Ha:
The test is two tailed
Standard Deviation –
= 2
z=(4.84-4)/(2/sqrt(63))
=3.33
Z(0.1/2)=1.645 is less than Z =3.334
Hence, we will reject H0
Hence, the average growth skier ski’s four times a year is not true
