Answer:

C. The points do not represent a function.

Step-by-step explanation:

In this case, this would have to make the most logical sense. A, B, and D say the exact same thing, so this would have to do.

* I know why you were confused, so I will clear it up for you. This is referring to linear equations like the Standard [Ax + By = C], Point-Slope [y - y₁ = m(x - x₁)], and Slope-Intercept [y = mx + b]. So, although we normally look for undefined slopes in this situation, this is one of the exceptions.

I am joyous to assist you anytime.

Hi There!

Change all the fractions to decimal you do that by dividing numerator by the denominator. Remember $\frac{1}{2}$ as a decimal is 0.5

A= $\frac{3}{7}$ = 0.43

B= $\frac{5}{9}$ = 0.60

C= $\frac{8}{10}$ = 0.8

D= $\frac{5}{12}$ = 0.42

E= $\frac{3}{5}$ = 0.6

Based, on the data above B,C,E are greater than $\frac{1}{2}$ because they all have decimals greater than 0.5, B= 0.6, C= 0.8, E=0.6

So, $\frac{5}{9} ,\frac{8}{10} ,\frac{3}{5}$ are all greater than $\frac{1}{2}$

Hope This Helps :)

35 points!! Only comment if you really know the answer please.

Y = 3x - 1 ---- (1)
x - y = -9 ---- (2)

From Equation 2:
x - y = - 9
x + 9 = y
y = x + 9 --- (2a)

(1) - (2a):
0 = 3x - x - 1 - 9
0 = 2x - 10
2x - 10 = 0
2x = 10
x = 5 ---- sub into (1)

y = 3(5) - 1
y = 15 - 1
y = 14

You and your friend are comparing two loan options for a $165,000 house. Loan 1 is a 15-year loan with an annual interest rate o

Harlamova29_29 [7]

Answer:

No, he is wrong.

Step-by-step explanation:

Since, the total payment of a loan after t years,

$A=P(1+r)^t$

Where,

P = present value of the loan,

r = rate per period ,

n = number of periods,

Given,

P = $165,000,

In loan 1 :

r = 3% = 0.03, t = 15 years,

So, the total payment of the loan is,

$A_1 = 165000(1+0.03)^{15}=165000(1.03)^{15}\approx \$ 257,064.62$

In loan 2 :

r = 4% = 0.04, t = 30 years,

So, the total payment of the loan is,

$A_2 = 165000(1+0.04)^{30}=165000(1.04)^{30}\approx \$ 535,160.59$

Since, $A_1 < A_2$

Hence, total amount repaid over the loan will be less for Loan 1.

That is, the friend is wrong.
