David's bowling score is 6 less than 2 times Aaron's score. The sum of their scores is 84. Find the score of each student. Use t
Y_Kistochka [10]

Answer:

Aaron's bowling score is 30

David's bowling score is 54

Step-by-step explanation:

The variable representing Aaron's score is = a

The variable representing David's bowling score = d

The sum of their scores is 84.

= a + d = 84...... Equation 1

David's bowling score is 6 less than 2 times Aaron's score.

d = 2a - 6

Substituting 2a - 6 for d in Equation 1

a + 2a - 6 = 84

3a - 6 = 84

3a = 84 + 6

3a = 90

a = 90/3

a = 30

Hence, Aaron's bowling score is 30

d = 2a - 6

d = 2(30) - 6

d = 60 - 6

d = 54

David's bowling score is 54

From the table below, determine whether the data shows an exponential function. Explain why or why not.
Ierofanga [76]
X        Δx                                   y             Δy

3                                               1          

1        1 - 3 = - 2                        2             2 - 1 = 1

-1        -1 - 1 = -2                      3              3 - 2 = 1

-3        -3 - (-1) = -2                  4               4 - 3 = 1


So, as you see y in increasing in regular constant intervals, when x also increases in regular constant intervals. => Δy / Δx = constant.

That is the result of a linear function, not an exponential one.

So, the true statement is given by the option <span>(A) No; the domain values are at regular intervals and the range values have a common sum 1. </span>

PLEASE HELP. TAKE AT HOME TEST. if u = LN5 and v = LN2, write LN8/15 in terms of u and v. (8/15 is 8 over 25)
astra-53 [7]

Answer:

\ln( \frac{8}{25} )  = 3v  -  2u

Step-by-step explanation:

We have that

u=  \ln(5)

and

v =  \ln2

This implies that;

5 =  {e}^{u}

and

2 =  {e}^{v}

Now find and expresion for

\ln( \frac{8}{25} )

Which is

\ln( \frac{8}{25} )  =  ln(8)  -  ln(25)

\ln( \frac{8}{25} )  =  ln( {2}^{3} )  -  ln(  {5}^{2} )

\ln( \frac{8}{25} )  = 3 ln( {2} )  -  2ln(5)

\ln( \frac{8}{25} )  = 3v  -  2u
