Answer: 48 stard
Step-by-step explanation:
12 stars = 30 balloons
? = 120 balloons
Solve
120/30 x 12 = 48
1) B irrational
2) B sometimes because a negative integer is not a whole number
3) C irrationals
4) C and D are whole numbers
5) C irrational
6) D 7/10 because a rational number is always a faction
7) C rational numbers
8) D real and rational
9) D rational, real, whole number
10) A integers
Answer:
The rate of change or slope m = -50
Step-by-step explanation:
The slope-intercept form of the line equation
where
- m is the rate of change or slope
Given that there is $500 in Holly's bank account.
Thus, the y-intercept b = 500
It is stated that she takes out $50 from her account each month but doesn't put money back in.
It means the rate of change or slope is decreasing.
Thus, the rate of change or slope m = -50
<u>EXTRA BONUS!</u>
We can also determine the line equation by substituting m = -50 and b = 500 in the slope-intercept form
y = -50x + 500
Here:
The slope m = -50
The y-intercept = 500
Answer:
x = 5/2 thì y = 35 và x = -5 thì y = 5
Step-by-step explanation:
thay y = 4x + 25 vào phương trình y = 2x ^ 2 + 9x ta có:
4x + 25 = 2x ^ 2 + 9x
⇒2x ^ 2 + 5x - 25 = 0
⇒ x = 5/2 và x = -5
thay x = 5/2 vào phương trình y = 4x + 25 ⇒ y = 4*(5/2) + 25 = 35
thay x = -5 vào phương trình y = 4x + 25 ⇒ y = 4*(-5) + 25 = 5
Answer: the amount of interest that Alyssa will pay on her loan is $1320
Step-by-step explanation:
The formula for determining simple interest is expressed as
I = PRT/100
Where
I represents interest paid on the loan.
P represents the principal or amount taken as loan
R represents interest rate
T represents the duration of the loan in years.
From the information given,
P = $22000
R = 4.5%
T = 4 years
Therefore,
I = (22000 × 1.5 × 4)/ 100
I = 132000/100 = $1320
