To move a graph up c units, add c to the whole function
so basicaly what you did is you subtraced 3 from the whole function
the whole graph shifts 3 units down
B is answer
False, because right angles are always going to be 90` while congruent angles are 110`
Gratuity is the total tip given.
The tip is directly proportional to total cost:
18/0.20 = x/1.00
$90
Y = 5x + b
Plug in the point
35 = 5(-8) + b
35 = -40 + b, b = 75
Solution: y = 5x + 75
Answer:
(1, 1 )
Step-by-step explanation:
Given the 2 equations
3x +2y = 5 → (1)
x - 2y = - 1 → (2)
Adding the 2 equations term by term will eliminate the term in y, that is
(3x + x) + (2y - 2y) = (5 - 1)
4x = 4 ( divide both sides by 4 )
x = 1
Substitute x = 1 in either of the 2 equations and solve for y
Substituting in (1)
3(1) + 2y = 5
3 + 2y = 5 ( subtract 3 from both sides )
2y = 2 ( divide both sides by 2 )
y = 1
Solution is (1, 1 )
