y = 1x + 5
Step-by-step explanation:
Because you pay $5 for the cup once, and to refill it, you have to pay $1 as how many times as you want.
Answer:
(4,1)
Step-by-step explanation:
point b is at (-1, 4) and the rule for 90 degree clockwise rotations is (y, -x) so it's (4, 1)
The common denominator is 40.
Answer: he invested $46062.5 at 6% and $23031.25 at 10%
Step-by-step explanation:
Let x represent the amount which he invested in the account paying 6% interest.
Let y represent the amount which he invested in the account paying 10% interest.
He puts twice as much in the lower-yielding account because it is less risky.. This means that
x = 2y
The formula for determining simple interest is expressed as
I = PRT/100
Considering the account paying 6% interest,
P = $x
T = 1 year
R = 6℅
I = (x × 6 × 1)/100 = 0.06x
Considering the account paying 10% interest,
P = $y
T = 1 year
R = 10℅
I = (y × 10 × 1)/100 = 0.1y
His annual interest is $7370dollars. it means that
0.06x + 0.2y = 7370 - - - - - - - - - -1
Substituting x = 2y into equation 1, it becomes
0.06 × 2y + 0.2y = 7370
0.12y + 0.2y = 7370
0.32y = 7370
y = 7370/0.32
y = $23031.25
x = 2 × 23031.25
x = 46062.5
Answer:
16
Step-by-step explanation:
you do 2+2 which is 4 then 8/2 is 4 and you multiple 4*4
