Answer:

not equivalent

Step-by-step explanation:

Given

$\frac{6}{7}$ = $\frac{7}{9}$

If the ratios are equivalent then ib cross- multiplying the 2 sides should be equal, that is

6 × 9 should equal 7 × 7

However, 54 ≠ 49

Thus the ratios are not equivalent

Solve the system by substitution. x – 3y = 4 2x – 6y = 8 A. no solution B. x = 4, y = 0 C. x = 0, y = 0 D. infinite solutions

ruslelena [56]

Answer:

The correct answer is option D.

Step-by-step explanation:

if the pair of equation has one or more than one solution then it is said to be consistent.

Only one solution , then independent system.
More than one solution , then dependent system.

if the pair of equation has no solution then it is said to be inconsistent.

Given : x - 3y = 4 ...[1]

2x - 6y = 8 ...[2]

Solution :

Solving equations with the help of Substituting methods:

x - 3y = 4

x = 4 +3y

Putting value of x from [1] in [2]:

$2(4+3y)-6y=8$

$8+6y-6y=8$

$6y=6y$

0 = 0

Given , system of equation will have infinite solution. Hence consistent and dependent.

The given system of equations will have infinite solutions.

Levi invested $5,300 in an account paying an interest rate of 2.4% compounded daily. Assuming no deposits or withdrawals are mad

suter [353]

Answer: $6,120.86

Step-by-step explanation:

Formula to calculate the accumulated amount in n years (compounded daily) is given by :-

$A=P(1+\dfrac{r}{365})^{365\times n}$

P= Initial amount

r= Rate of interest ( in decimal)

As per given , we ahve

P= $5300

r= 2.4%=0.024

n= 6 years

Put these values in formula , we get

$A=5300(1+\dfrac{0.024}{365})^{365\times6}\\\Rightarrow\ A=5300(1.00006575342)^{2190}\\\Rightarrow\ A=6120.85673631\approx6120.86$

Hence, there would be $6,120.86 in the account after 6 years.
