Answer:

Choice A is the answer.

Step-by-step explanation:

We have given a function.

h(x) = -2x+7

We have to choose the ordered pair which doesn't lie on the graph of given function.

A. (-2,3)

Putting x = -2 in given function, we have

h(x) = -2(-2)+7

h(x) = 4+7

h(x) = 11      (false)

B. (-1,9)

putting x  = -1 in given function, we have

h(x)  =  -2(-1)+7

h(x)  =  2+7  =  9      (true)

C. (3,1)

Putting x  =   3 in given function, we have

h(x)  =   -2(3)+7

h(x)  =   -6+7

h(x)  =   1      (true)

D. (4, -1)

Putting x  = 4 in given function, we have

h(x)  =   -2(4)+7

h(x)  =  -8+7

h(x)  =  -1       (true)

Answer: A (-2, 3)

Step-by-step explanation:

1. To know which oredered pairs does not lie on the graph, you must substitute the x-coordinate of each one of thm into the function and if you obtain the y-coordinate shown in that ordered pair, then that point lies on the graph.

2. Therefore, you have:

A. x=-2

h(x)=-2(-2)+7=11 (It does not lie on the graph).

B. x=--1

h(x)=-2(-1)+7=9 (It lies on the graph).

C. x=3

h(x)=-2(3)+7=1 (It lies on the graph).

D. x=4

h(x)=-2(4)+7=-1 (It lies on the graph).

Therefore, the answer is the option A.

Bas_tet [7]

Answer:

Amount she would have in 2 years at a simple interest of is

$5000 + ($5000 x 0.048 x 2) = $5480

Amount she would have in 2 years at a 4.1 % / year compounded semi- annually is :

$5000 x ( 1 +0.041/2)^4 = $5422.78

the first option yields a higher value in two years when compared with the second option. Thus, the first option is the best one to choose

Step-by-step explanation:

Future value with simple interest = principal + interest

Interest = principal x interest rate x time

0.048 x 5000 x 2 = 480

future value = $480 + 5000 = $5480

The formula for calculating future value with compounding:

FV = P (1 + r)^nm

FV = Future value  

P = Present value  

R = interest rate  

m = number of compounding

N = number of years

5000 x ( 1 + 0.041 / 2)^(2 x 2) = $5422.78

Suppose that two cards are randomly selected from a standard​ 52-card deck. ​(a) what is the probability that the first card is
Savatey [412]
(a) without replacement:
P(S)=13/52=1/4
P(SS)=(1/4)*(12/51)=1/17
Probability of selecting two spades without replacement is 1/17.

(b) with replacement
P(S)=13/52=1/4
P(SS)=(1/4)(13/52)=1/16
Probability of selecting two spades with replacement is 1/16.

Answer:

- 508

Step-by-step explanation:

The n th term of an arithmetic sequence is

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 28 and d = - 34 - (- 28) = - 34 + 28 = - 6, thus

a_{81} = - 28 + (- 6 × 80) = - 28 - 480 = - 508
