Answer: f(0) = 6.
Explanation:
Ther ordered pairs are: (x,y) or (x, f(x) )
So, (1,0) means that f(1) = 0 which denies the fourth choice.
(-10,2) means that f(-10) = 2 which denies the first choice
(0,6) means that f(0) = 6, which is the third choice. So, that is the true equation.
Answer:
Sister = 15 years old
Brother = 12 years old
Step-by-step explanation:
Right now, if the brother is B years old and the sister is S years old, B = (4/5)S because the ratio from brother to sister is 4:5, so if one unit is X, B = 4X and S = 5X
Three years ago, the brother was B-3 years old and the sister was S-3 years old. Keeping one unit as X, we have
B = 3X
S = 4X
B-3 = (3/4)(S-3)
Therefore, we have a system of equations
B = (4/5)S
B-3 = (3/4)(S-3)
Substitute (4/5)S for B into the second equation to only have one variable
(4/5)S - 3 = (3/4)(S-3)
(4/5)S - 3 = (3/4)S - 9/4
add 3 to both sides and subtract (3/4)S from both sides to isolate the variable and its coefficient
(1/20)S = 3/4
multiply both sides by 20 to isolate the S
S = 15
B = (4/5)S = 12
Answer:
C
Step-by-step explanation:
total cost=53.99+53.99×7/100=53.99+53.99×.07)=53.99(1+.07)=53.99(1.07)
Answer:
<h2>The dimensions of the third blanket are 7.5 feet by 6 feet.</h2><h2>All the blankets are similar.</h2>
Step-by-step explanation:
The size of the first blanket is 2.5 feet by 2 feet.
Shannon wants to enlarge the first blanket by scale factor 2 to make the second blanket.
Hence, the size of the second blanket will be 
feet by 
feet.
Again she enlarged the second blanket by a scale factor 1.5 to make the third blanket.
Hence, the size of the second blanket will be 
feet by 
feet.
Enlargement only changes the size of the blanket, it does not change the shape of the blanket. Hence, all the blankets will be similar.
