Answer:

the first option

Step-by-step explanation:

it is directly there in the problem description.

f(x) = 1.8x - 10

g(x) = -4

so, for f(x)=g(x) that automatically means

1.8x - 10 = -4

1.8x = 6

x = 6/1.8 = (6/1) / (18/10) = 10×6 / 18×1 = 60/18 = 10/3

Can someone answer this question please answer it correctly if it’s corect I will mark you brainliest
Daniel [21]

Answer:

getting the queen is smaller

5/8

Step-by-step explanation:

There are 4 queens in a 52 card deck

P(queen) = 4/52 = 1/13

There are 12 pairs socks, 3 of which are grey

P(grey socks) = 3/12 = 1/4

1/13 <1/4

So getting a queen is smaller

The possible outcomes

8 +0  9+0   10+0  <em> 11+0</em>

8+1    9+1 <em>    10+1    11+1</em>

8+2<em>   9+2     10+2    11+2</em>

<em>8+3   9+3     10+3    11+3</em>

There are 16 outcomes and 10 of them are after 11, (assuming we add the time to the bedtime)

P (bedtime later than 10) = 10/16 = 5/8

Simplify the expression.<br> - (m<br> m + 3n - 13)
natulia [17]

Answer:

=  -  {m}^{2}  - 3n + 13

Step-by-step explanation:

- (m \times m + 3n - 13)

m \times m =  {m}^{1}  \times m

{m}^{1}  \times  {m}^{1}  =  {m}^{1 + 1} =  {m}^{2}

- ( {m}^{2}  + 3n - 13)

=  -  {m}^{2}  - 3n + 13
