Answer:
Step-by-step explanation:
A) 5x = 3(x - 2.5)
-----------------------
B)
Distribute
5x = 3x - 7.5
Subtract 3x from both sides
2x = -7.5
Divde both sides by 2
x = -3.75
-----------------------
C)
5 * (-3.75) = 3(-3.75 - 2.5)
-18.75 = -18.75
D)
Tanya paid –$3.75 for each of 5 items
Tony paid –$6.25 for each of 3 items
There seems to be an error in the question since the cost of items is negative
Tony bought fewer items and paid less for each.
Answer:
(3x + 10) / (2x + 5)(x - 5).
Step-by-step explanation:
(3/2x+5) + (5/x-5)
= [3(x - 5) + 5(2x + 5) ] / [ (2x + 5)(x - 5)]
= 3x - 15 + 10x + 25 / (2x + 5)(x - 5)
= 13x + 10 / (2x + 5)(x - 5).
Slope = (2 + 1) / (-5 - 10) = -3/15 = - 1/5
Equation
y - 2 = -1/5 (x + 5)
y - 2 = -1/5 x - 1
y = -1/5 x + 1
Answer
y = -1/5 x + 1
Answer:
B
it's a recurring number therefore it's irrational
Answer:
Positive co terminal angle = -105°
Negative co terminal angle = 225°
Step-by-step explanation:
We have been given the angle 75° and we have to find one positive and one negative co-terminal angle.
In order to find the co terminal angle, we add and subtract 180° to the given angle.
Therefore, the negative co terminal angle is given by
75 - 180 = -105°
And the positive co terminal angle is given by
75 + 180 = 225°
