Answer:
62
Step-by-step explanation:
5-3(-19)
-3(-19)= 57
57+5=62
Answer:
x = negative 9 or x=-9
Step-by-step explanation:
4x+24=2x+6. We can subtract 6 from both sides to get
4x+18=2x. After that, we can switch the sides to get
2x-18=4x, so negative 18 (-18) is equivalent to 2x. We get
2x=-18, divide both sides by 2 to get x=(-9).
Answer:
x = 7
Explaination:
ABC = 40°
and BD bisects the angle so ABD = 20°
so 3x-1=20
solving for x gets us
x = 7
Answer:
D. y=4x
Step-by-step explanation:
It asks for a proportional relationship between x and y
And is the only answer
because
When x and y is 1 the answer is
4/1
And when x and y is 2 the answer is
8/2
If you divide both of them are still 4
And this will always be the result no matter how many times you do it
like if you put it as 150
150 times 4 is 600/150
600 divided by 150 is 4
Hope this helps!
<u>Answer-</u>
<u>Solution-</u>
Here, n represents the number of months and f(n) represents the number of laptops in the store after n months.
As the store had 150 laptops in the month of January or at the beginning.
So 
Every month, 20% of the laptops were sold and 10 new laptops were stocked in the store.
As 20% of laptops were sold, so 80% were in the store.
So, after one month total number of laptops in the store,
Again after one month total number of laptops in the store,
Analyzing the pattern, the recursive function f(n) will be,
