Answer:

-x-30

Step-by-step explanation:

first you need to distribute:

3(x)+3(-6) -4(x)+ (-4)(3)

Then you multiply:

3x+(-18)-4x+(-7)

then you combine like terms:

3x-4x= -1x

-18+(-7)= -25

simplified:

-1x-30

Rudiy27

A door alarm works in 72 out of 100 cases.

surveillance camera works in 68 out of 100 cases.

The probability that method A is used = 72/100

The probability that method B is used = 68/100

Since both method are used we find the probability of A and B

Probability ( A and B) = $\frac{72}{100}$ * $\frac{68}{100}$

= $\frac{306}{625}$

Which ordered pairs in the form (x, y)(x, y) are solutions to the equation

Scilla [17]

4x - 5y = 24

4(6) - 5(0) = 24
24 - 0 = 24
24 = 24 (correct)....so (6,0) is a solution

4(1) - 5(-4) = 24
4 + 20 = 24
24 = 24 (correct)...and (1,-4) is a solution
