Answer:
s=d/t
=10/20=1/2
d=150
s=1/2
t=d/s
t=150/1/2
t=150/2
t=70
Step-by-step explanation:
okay?need thanks
3x - 3y = -12 ------------- (1)
7x + 2y = -19 --------------(2)
(1) x 2 : 6x - 6y = - 24 ----------- (1a)
(2) x 3 : 21x + 6y = -57 ----------- (2a)
(1a) + (2a) : 27x = - 81
x = - 3
Sub x = -3 into (1) : 3(-3) - 3y = - 12
y = - 12 + 9
y = - 3
Answer( -3, -3)
Answer:
C is correct
Step-by-step explanation:
Comparing the to equation with slope intercept form: 
The second equation has the greatest slope, which is indicating that the line is steeper.
a) f (2) = 1
b) 
c) 
<u>Step-by-step explanation:</u>
- Indicates that we have to find the inverse of the function
Given data:
--------> eq.1
---------> eq.2
To find 
Case a)
Now, substitute x = 2 in the equation 1 to find f (2)

Case b)
Now, substitute x = 1 in the equation 2 to find 

Case c)
In general,

Thereby,

The answer is -5 just put it in the calculator
