Answer:
There are an infinite number of solutions.
Step-by-step explanation:
An equation with 2 unknowns give an infinite amount of solutions, here is just one of the many:
Let y= 3 ( y can be any number)
(3) + 1 = -4x
4 = -4x
x = -4/4
x= -1
(x;y) = (-1;3)
Generally x and y can be any number, just let x or y be any number, then find the other variable based on the value of the number u assumed.
36, 43, 50, 57, 64
36 and 64 are two standard deviations out, so the empirical rule tells us 95% of scores will fall here with a normal distribution

The probability of drawing a 7 or 8 from a decl of playing cards is 2/13.
Answer:4) 1. (3^4)^3=3^12 ,
2.(-10^3)^6=-10^18 others are similar...
5) 1. (2^7/2^5)=2^2,4 ,
2.(a^7/a^3)=a^4 ,
7. [(-4)^3 x (-4)^5)]/[ (-4)^2 x(-4)^3]=4^3 others are similar...
Step-by-step explanation: 4)1. step1. 3^(4x3) , 2. step1. -10^(3x6)
step2. 3^12 , step2. -10^18
5)1. step1. 2^(7-5) , 2. step1. a^(7-3)
step2. 2^(2) , step2. a^(4)
7. step1. -4^(3+5)/-4^(2+3)
step2. -4^(8)/-4^(5)
step3. 4^(8-5)
step4. 4^(3)
Answer:
RST= 105 degrees
Step-by-step explanation:
it would be 2(5x+15) + 2(4x+3) =360
10x+30+8x+6=360
18x=324
x=18
so RST=5x+15=5(18)+15=105
