Answer:
y = -x + 2.
or
x + y - 2 = 0 (Standard form).
Step-by-step explanation:
Its slope (m) is -1 and y intercept (c) is at y = 2.
y = mx + c
So it's:
y = -1x + 2
Standard form is:
x + y - 2 = 0.
I'm not sure what you mean by General Form.
Answer:
(52, 32 )
Step-by-step explanation:
Given the 2 equations
y = x - 20 → (1)
x + y = 84 → (2)
Substitute y = x - 20 into (2)
x + x - 20 = 84, that is
2x - 20 = 84 ( add 20 to both sides )
2x = 104 ( divide both sides by 2 )
x = 52
Substitute x = 52 into (1) for corresponding value of y
y = 52 - 20 = 32
Solution is (52, 32 )
Answer:
b.) f(t) = 216 - 66t
Step-by-step explanation:
Since we consider t and time travelled in hours and we are given that the average speed of Jon is 66mph, then we can calculate the distance travelled at any point in time by Jon.
Distance = Speed * time.
Distance = 66 * t = 66t.
Since total distance from clients house 216 miles and distance travelled by Jon at any point in time is 66t, then remaining distance to be covered from the clients house, that is distance between Jon and the clients house becomes:
Distance from client house = 216 - 66t.
Step-by-step explanation:
y = 2x - 15
4x + 3y = -5
4x + 3(2x - 15) = -5
4x + 6x - 45 = -5
10x = 40
x = 40/10
x = 4
y = 2x - 15
y = 2(4) - 15
y = 8 - 15
y = -7
Solution = (4,-7)
Option → C
