Step-by-step explanation:
hope this helps tell me if it's right
6×5=30. the sum of the five numbers is 30. then just do 30-7-8-5-2=8. 8 is the number on the bottom card.
8x + 20 - 11 = 4x - 3
8x + 9 = 4x - 3
8x + 12 = 4x
12 = -4x
-3 = x
X = -3
9m+5=-13
9m=-18
m=-18/9
m=-2
Answer:
y=6x+20
Step-by-step explanation:
m= y2-y1/x2-x1
m= -4-8/-4-(-2)= 12/-2= 6/1
y= mx+b
y= 6x+b
8= 6(-2)+b
8=-12+b
+12 +12
b= 20
