Substitute -1 for x
2(-1)+3=
-2+3=
1
answer is 1 because you subtract 3 from 2 and the answer is positive because 3 is higher than 2..if I were you I'd pick B
Answer:
171.85 cm
Step-by-step explanation:
Given data
We are given that the distance = 149 cm 415in
Let us mark the units uniform by converting inches to cm
1 inches = 2.54cm
415 inches= x cm
cross multiply
x= 415*2.54
x= 1054.1 cm
Hence the total distance in cm is 1054.1+149= 1203cm
If in 7 days he travels 1203cm
in 1 day he will travel x cm
cross multiply
7x= 1203
divide both sides by 7
x= 1203/7
x= 171.85 cm
First set both equations equal to y
y = -1/2x + 3
y = 3x - 4
Then set these two equal because they both equal y
-1/2x + 3 = 3x + 4
Combine like terms and solve
7 = 3.5x
x = 2
y also = 2 when you plug it back in
Therefore, (2,2)
Answer:
Step-by-step explanation:
We have to follow these rules:
+/+ = +
-/- = +
+/- = -
-/+ = -
so
positive numbers:
+2/+3 ; -2/-3 ; -1/-3 ; +1/+3
negative numbers:
+2/-3 ; -2/+3 ; -1/+3 ; +1/-3
I honestly don’t know man but don’t worry, if you get a bad score it won’t matter in 30 years :)
