Answer:
$25.57
Step-by-step explanation:
First, you have to multiply $5.29 by 2 because she wants to spend $5.29 on 2 pairs of socks.
5.29 * 2 = $10.58
Then you want to add $10.58 and $14.99 together.
$10.58 + $14.99 = $25.57
The slope of the line l is the opposite reciprocal of y+2x=9. Rearranged the equation to y=9-2x and we get a slope of -2. The opposite reciprocal of -2 is 1/2.
y-y=m(x-x)
y-3=.5(x-4)
y=.5x+1
At the x-intercept, y=0, so
0=.5x+1
-1=.5x
x=-2
The slope-intercept form: y = mx + b
We have the slope m = 9, therefore: y = 9x + b.
Next. We have the table:
x | -5 | -2 | 1 | 3 | 4 |
y |-46|-19| 8 |26|35|
(1, 8) → x = 1, y = 8
substitute the values of x and y to the equation:
8 = 9(1) + b
8 = 9 + b |-9
b = -1
Answer: y = 9x - 1 → y-intercept is -1.
Answer:
2.6%
Step-by-step explanation:
Given the current CPI = 231.56
Previous CPI (CPI a year ago) = 225.3
Rate of inflation over the past year = current CPI - previous CPI/previous CPI × 100%
Rate of inflation = 231.56-225.3/225.3 × 100%
5.86/225.3× 100%
= 2.6%
Rate of inflation over the past year will be 2.6%
Odd integers are represented by 2n+1 where n is a whole number
consecutive odd are 2 apart so
they are 2n+1 and 2n+1+2
the sum of them is at least 16
2n+1+2n+1+2<u>></u>16
4n+4<u>></u>16
minus 4
4n<u>></u>12
divide 4
n<u>></u>3
sub back
2n+1 and 2n+3
2(3)+1 and 2(3)+3
6+1 and 6+3
7 and 9
they have to be at least 7 and 9
