Answer:
-1 * (-3)^2 - 12 = -1 * 9 -12 = -9 - 12 = -21
Step-by-step explanation:
(A) 4(x+5). Distribute the 4 (multiply both numbers by 4) and you get
4x+4*5
4x+20
(B) 70 km/h * y hours is 70y km, because you traveled 70 km every hour, so it's 70 times y.
Answer:
Addition and subtraction property of equality
Step-by-step explanation:
because -8-×=9.
Answer:
Option C
Step-by-step explanation:
In this case, an exponential function is a function that has common ratio whereas it is called a linear function if it has common difference.
Option A:
Since the values of y in the given table have different ratio but common difference, therefore it is not a a linear and not an exponential function. Option A is is not correct.
Option B:
Since the values of y in the given table have different ratio but common difference, therefore it is not a a linear and not an exponential function. Option B is not correct.
In option C.
Since the given values of y in the table have a common ratio, it is said to be an exponential function.
Option C is correct.
In option D.
Since the values of y in the given table have different ratio but common difference, therefore it is not a a linear and not an exponential function. Option D is incorrect.
Answer:
First you have to find x.
A stratight line is 180 degree.
Therefore, we have:
16x+8+4x-8=180
20x= 180
x= 9
Angle BAT = 16x+8= 16(9)+8= 152 degree.
Angle CAT= 180-152= 28 degree.
