Pls answer! I don’t know math at all

The solutions of the system of equations are (–2, 4) or (–5, 1).

Solution:

Given equations are:

– – – – (1)

– – – – (2)

Equate the values of y.

Subtract 6 from both sides of the equation.

Subtract x from both sides of the equation.

Switch the sides.

Factor this polynomial, we get

x + 2 = 0 (or) x + 5 = 0

x = –2 (or) x = –5

Substitute x = –2 in equation (1),

y = –2 + 6

y = 4

Substitute x = –5 in equation (1),

y = –5 + 6

y = 1

The solutions of the system of equations are (–2, 4) or (–5, 1).

2.   never

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages
