Answer:
3-(-2)=3+2 {The negative signs will become +)
and 3+2=5
so option 4 is correct
Y=3x+3
Perpendicular lines have the product of their gradients =-1
since gradient of line 1 =-1/3
then gradient of line 2 is
-1/3*m=-1
m=3
Answer:
Trevor has 16 number of shirts
Step-by-step explanation:
We have been given that Trevor and Marisa together have 28 t shirts to sell if Marissa has 4 fewer t shirts than Trevor
let the number of shirts Trevor have be x
And since, Marissa has 4 fewer than Trevor so number of shirts Marissa will have be x-4
Hence, according to question equation becomes:
x+x-4=28
We will solve for x to find the number of t shirts Trevor has
2x -4 =28
2x = 32
x =16
Hence, Trevor has 16 number of shirts
1) 40+7=47
2) 47+7= 54
3) 54+7 = 61
4) 61+7 = 68
The answer is 68.
