the sequence is adding 2 to each last number
5 + 2 = 7
7 +2 = 9
9 + 2 = 11
11 + 2 = 13
13 + 2 = 15
the answer is D. 15
Answer:
96
Step-by-step explanation:
Basically you're multiplying how many coins you have that year by eight.
The fist year you had 4 coins. 4 multiplied by 8 equals 32. Mrs Bradford had 32 coins.
The second year you had 6 coins. 6 multiplied by 8 equals 48. Mrs Bradford had 48 coins.
The third year you had 8 coins. 8 multiplied by 8 equals 64. Mrs Bradford had 64 coins
For the fourth and fifth year you have to add 2 for each year.
So for the 4th year you had 10 coins and 10 multiplied by 8 equals 80. Mr.Bradford had 80 coins.
And Finally for year five you had 12 coins. 12 multiplied by 8 equals 96. Mr.Bradford had 96 coins in year five.

Step-by-step explanation:
Answer:
y = - x - 4
Step-by-step explanation:
A line perpendicular to the line: y = x + 5
must have a slope that is the "opposite of the reciprocal" of the slope of the given line. Then the slope of the perpendicular line must be "-1".
Now that we know the slope of the perpendicular line, we use the point (-7, 3) to complete the equation of the line:
y = -1 x + b
3 = -1 (-7) + b
then we solve for "b":
3 = 7 + b
3 - 7 = b
b = -4
Now we can write the total equation of the perpendicular line in slope-intercept form as:
y = - x - 4
