Which statement describes the system of equations?

Mathematics
1 answer:
lidiya [134]4 years ago
6 0

Step-by-step explanation:

7y = 9x-27

sub 7x = 9x-27 into 2nd eqn

45 + (9x-27) = 9x

move 9x over

18 = 9x - 9x

18 = 0

this doesn't make sense, so eqn has no solution

Write x as a logarithm in the following: 10^x=7
pochemuha

Answer:

x = log 7

Step-by-step explanation:

10^x=7

Take the log base 10 on each side

log10 (10^x)=log10 (7)

We dont need to write the 10, it is implied

log(10^x)=log (7)

The exponent  goes out front since log a^b = b log a

x log 10 = log 7

log 10 = 1 since the base is 10 log10(10) =1

x = log 7

Which integer represents 50 degree below zero?<br> A- 50<br> B- 0 <br> C- -25<br> D- -50
scZoUnD [109]

Answer:

D) -50

Step-by-step explanation:

The answer is D.

Numbers below zero would be negative. This eliminates B and A, as they are positive.

Numbers above zero are positive.

<em>The answer is not C because that would be 25 degrees below zero</em>, not 50 below.

That leaves us with D. D is -50, which is also stated as "50 below zero".

So, our best answer would be D.
