Answer:
X=3,y=-2
Step-by-step explanation:
This is a simultaneous equation question and we will have to solve using substitution method
So let's solve
y=-2x+4...(1)
y=-2....(2)
Let's substitute (2) into (1)
-2=-2x+4
Substrate 4 from both sides
-6=-2x
Divide both sides by-2
x=3
Substitute the value of x in (1)
y=-2(3)+4
y=-6+4
y=-2
Therefore x is 3,y is -2

Answer:
Part A: $60
Part B: $54
Step-by-step explanation:
Answer:
= 22 + 3,0 + 1 = 36
= -20 + 3 = -17
= -62 + 10 = -52
= 2 x (-7) = -14
= (-322) - 30 + 11 = 281
Follow me // i'm Followback you
part A is just simple multiplication
since there are 2 6 sided number cubes there are 36 possible outcomes(6 sides *6 sides)
Part B is a little trickier. First off, you must find how to get seven.
1. 1+6 and 6+1
2. 2+5 and 5+2
3.3+4 and 4+3
therefore there are six combinations
you put that number over the total combos and get 6/36 or 1/6.
Hope this helps!
