Answer:
y = -x + 3.
Step-by-step explanation:
The slope of line q is 1.
The slope if the line r = -1/m = -1/1 = -1.
So we can write r as y = -x + b.
When x = 10 y = -7 on line r so
-7 = -10 + b
b = -7 + 10
b = 3
Line r is y = -x + 3.
Briana is wrong. The 2 line cannot be parallel since their slopes are not the same. The slope of one line is 2 and the slope of the other is 2.5.
The other student is right. Just replace (9, 21.5) in both equations and it will satisfy both equation.
Answer: 57.59- 56.3=1.29
Step-by-step explanation:
57.59-x = 1.29
-x= 1.29-57.59
(—) -x= - 56.3
x=56.3
Interval <-1;1>, which means that this function can take values from interval <-7;-1>. The minimum value is -7.
