Answer:
5+ 3x
Step-by-step explanation:
The answer is 4 bc 4a+8b+4c=1. 4a*4=16a 8b*4=32b and 4c*4=16c so 1*4=4. since ur finding four times as much of the first problem then 16a+16c+32b=4
Answer:
$10,400
Step-by-step explanation:
If 2,000 dollars are being invested at the beginning of each year and gets a 4% interest at the end that means 2,000*104%=$2,080
It also continues on for 5 years so 2,080*5=$10,400
1,040 teenagers do not enjoy going to the movies out of 5,200. 80% of 5,200 is 4,160. You would have to subtract 4,160 from 5,200 which is 1,040.
Step 1: find slope intercept form using the given point and the slope
y - 14 = 21/2(x - 9)
y - 14 = 21/2x - 94.5
y = 21/2x - 80.5
now plug in your given y value and solve for x
-7 = 21/2x - 80.5
73.5 = 21/2x
x = 7
