You need to use y=mx+c to answer this so basically
gradient/slope (m) is 1.5 and the y-intercept (c) is -2
Hope this helps :)
G (x) = 2(-2)-2 f(x)=(2)^2+5
=-4-2 =4+5
=-6 =9
-6×9= -54
Answer:
9 it is easy answer
don't forget to make me brainlist
W+d=869
w=d-81
plug in
(d-81)+d=869
2d-81=869
+81 both sides
2d=950
÷2 both sides
d=475
dryer cost $475
let's check w=475-81
w=394
475+394=869
869=869
the solution is true :)
It is (0,5). If you plug in 0 for x and 5 for y, then you will see that the inequalities are true.
