Answer:
10x-2x-4=8x-4 اتمنى لك التوفيق
3x-4 = -10
3x-4 +4 = -10 +4
3x = -6
then you can divide it :
x = -6 : 3
x= -2
Step-by-step explanation:
i really dont know tbh that confusing
Fourth test mark should be 86
85 + 82 + 75 + 86 = 328
328 divide by 4 (as there are four tests) = 82
F(x) is the same as y. so you’d choose two coordinates and do y2-y1 over x2-x1. id recommend doing that with whole numbers, no decimals. by doing that you get your slope.
