A and F are true. because A is y=2x+7, and F is y=2x+7.
We know that the equation y=2x+7 has a point 0,7 and with the slope being 2, rise over run would make another point 1,9. And because these are linear equations if the equation y=2x+7 goes through 1,9 then it will go though -2,3 as well.
Given:
Claire is 2 year younger than her sister.
The sum of ages is no less than 44 years.
To find:
Inequality and find the youngest age Claire can be.
Solution:
Let the age of Claire be x.
Her sister's age = x+2
Sum of their ages is no less than 44 years. It means the sum ages is greater than or equal to 44.
Divide both sides by 2.
It means, Claire age can be greater than or equal to 21. So, the youngest age Claire can be 21 years old.
Therefore, the required inequality is and the correct option is B.
Answer:
69
Step-by-step explanation:
Principal amount of money deposited by Mat in the bank = $2000
Rate of simple interest given by the bank = 10%
Number of years for which the money is kept in the bank = 5 years
As no money was withdrawn from the account, so
Amount after 5 years = Principal [1 + (Rate * Time)]
= 2000 [ 1 + (10/100) * 5]
= 2000 [ 1 + (1/2)]
= 2000 * (3/2)
= 1000 * 3
= 3000 dollars
So the amount of money made by Mat after 5 years will be $3000.00
The answer is Y= (x-2)^2-5
