The tip is $6.21
with that being said, 34.50 + 6.21 = 40.71
the total cost is $40.71
3. No it is not on the graph.
because: y=2x+5 insert (5,6)
6=2x5 +5 is wrong
4. C
4x=-3y+17 becomes 4x+3y=17
4x+3y=17
3x-4y=-6
alrighty
elimination
muliply first equation by 4 and 2nd by 3 and add them
16x+12y=68
9x-12y=-18
add them
25x+0y=50
25x=50
idivide both sides by 25
x=2
sub back
3x-4y=-6
3(2)-4y=-6
6-4y=-6
-4y=-12
y=3
(x,y)
(2,3)
Answer:
Step-by-step explanation:
Answer:
x = -5
Step-by-step explanation:
These are alternate exterior angles and alternate exterior angles are equal
110 = x+115
Subtract 115 from each side
110-115 = x+115-155
x = -5
