Answer:
5) x = 1, y = -3
6) x = -20, y = 2
7) infinite solutions
8) no solutions
Step-by-step explanation:
5)
y = 5x - 8
y = -6x + 3
5x - 8 = -6x + 3
11x = 11
x = 1
y = 5 - 8
y = -3
6)
2x + 10y = -20
-x + 4y = 28
2x = -20 - 10y
x = - 10 - 5y
-x = 28 - 4y
x = -28 + 4y
-10 - 5y = -28 + 4y
-10 + 28 = 4y + 5y
18 = 9y
2 = y
2x + 20 = -20
2x = -40
x = -20
7)
this has infinite solutions because one equation is a simplified version of the other
8)
this has no solutions because 5 does not equal -5
9)
I can't graph on brainly, hope this helped though
Answer:
Range: 22
Median: 79
Mode: 80
Step-by-step explanation:
I hope this helped and have a nice day! Also can I have brainliest?
Divide both sides with 9
s = 16
Point-slope form :-
... y = mx + b
<em>In this equation, 'm' represents the slope and 'b' represents the y-intercept. </em>
Given :-
... y = -1/7x + 2
<u><em>Hence, the slope is -1/7 and y-intercept is 2 or ( 0 , 2 ) </em></u>
Hope it helps!!
