Out of those 2 answers I believe your answer would be B only because 81% of Americans in the us have a phone and 35% of people in the us check there phone more than 50 times per day
Answer:
ten " subtracted from twice a number" is...so 20- 10=10
or
10-5=5
Step-by-step explanation: I don't really understand this question sorry if I got it wrong!
Have a Great Day or Night! :)
D.Add 2x, then subtract 23, lastly divide by 7
the other answers would be incorrect because
you are supposed to subtract what's positive and add what's negative
Anyway, this would leave us with two possible answers ( a and d)
Answer:
Step-by-step explanation:
Exponential functions are represented in the form 
, where a is the initial value and b is the multiplier.
Here, we see that when x = 0, y = 4. This means that 4 is our initial value, or a. You can look at the a variable almost being like the y-intercept of a graph.
Next, we must solve for b. We can do 16 ÷ 4 to find the slope, or multiplier of this function, because 16 is 1 input x-value up from 0. 16 ÷ 4 = 4.
So, we now have all the needed variables, so we plug them into the formula
For #1 the answer would be ; " y = - x - 4 "
( you just have to plug in the given numbers to the slope intercept form )
