Answer:

71 and 19

Step-by-step explanation:

Numbers are x and y, equations below:

x + y = 90
x = 3y + 14

Substitute x in the first equation:

3y + 14 + y = 90

Solve for y:

4y + 14 = 90
4y = 76
y = 19

Find x:

x = 90 - 19 = 71

4x+4y=0 -10x— 4y=-18

-BARSIC- [3]

we can use elimination to solve these

add the two equations together

4x+4y=0

-10x— 4y=-18

--------------------

-6x = -18

divide each side by -6

x = 3

4x + 4y = 0

substitute in x=3

4*3 + 4y =0

12 + 4y =0

subtract 12 from each side

4y=-12

divide by 4

y = -3

x=3, y= -3

write the logarithm as a sum or difference of logarithms. simplify each term as much as possible. log4(6ab)

Dominik [7]

The logarithm written as a sum of logarithm and simplified as much as possible is $\frac{1}{2} +log_{4 }3 + log_{4 }a + log_{4 }b$

<h3>Simplifying Logarithms</h3>

From the question, we are to write the given logarithm expression as a sum or difference of logarithms

The given logarithm is

$log_{4 }6ab$

This can be written as

$log_{4 }6 \times a \times b$

From one of the rules of logarithm, we have that

$log_{x }yz= log_{x }y + log_{x }z$

Thus,

$log_{4 }6 \times a \times b$ becomes

$log_{4 }6 + log_{4 }a + log_{4 }b$

This can be further simplified into

$log_{4 }3 \times 2 + log_{4 }a + log_{4 }b$

$log_{4 }3 + log_{4 }2 + log_{4 }a + log_{4 }b$

If desired, this can be further simplified into

$log_{4 }3 + log_{2^{2} }2 + log_{4 }a + log_{4 }b$

$log_{4 }3 + \frac{1}{2} log_{2}2 + log_{4 }a + log_{4 }b$

$log_{4 }3 + \frac{1}{2} (1)+ log_{4 }a + log_{4 }b$

$\frac{1}{2} +log_{4 }3 + log_{4 }a + log_{4 }b$

Hence, the logarithm written as a sum of logarithm and simplified as much as possible is $\frac{1}{2} +log_{4 }3 + log_{4 }a + log_{4 }b$
