Answer:
x = 15
Explanation:
First, add both equations on one side, and set it equal to 180° because it's supplementary:
2x + 8 + 8x + 22 = 180
combine like terms:
10x + 30 = 180
subtract 30 on both sides of the equation and you end up with:
10x = 150
divide both sides by 10 and you get:
x = 15
Let x be the amount earned by Tony. With this representation, Jennifer earned 2x - 40 and Chris earned x + 60. The amounts they earned should sum up to 900. The equation is,
x + (2x - 40) + (x + 60) = 900
The value of x is 220. Therefore, Tony earned $220. Jennifer and Chris earned $400 and $280, respectively.
Answer:
- The next term of the sequence is represented by the point (5, –64)
Step-by-step explanation:
<u>Note:</u> <em>The first point should be (1, - 4)</em>
According to the points, the sequence is:
- t₁ = - 4, t₂ = 8, t₃ = - 16, t₄ = 32
or
We can observe it is a geometric sequence with common ratio of - 2, as:
- r = 32/ - 16 = - 16/8 = 8/ - 4 = - 2
The following term is:
- t₅ = t₄*r = 32*(- 2) = - 64
The coordinates of same term are:
As we see the correct answer choice is D.
Answer: 80 degrees because a line is 180°.
So if you subtract
180 - 100 = 80°
The expression given represents an exponential growth relation. The average rate of change is the <em>average growth of the flower from day 1 to days 5 </em>
The rate of change of the flower can be deduced frommthe equation as :
Hence, the growth rate of the flower per day = 0.02
The number of days, n = 5
Therefore, the average growth rate is the average growth of the flower within the number of days given.
