are you trying to add them all together if so here how that would work
4x-3x=1x
2y-(1)y =1y(if the y is alone theirs a 1 always infront of it)
-14-8=-22
Answer:
B or C,i think. I'm not sure though
7/5 x 7/1 = 49/5 or 9 4/5
Answer:
eflect across y axis means that you replace x with -x
f(-x)=2(-x)=-2x
g(x)=-2x
de graph is the one that passes through (0,0) and (1,-2) and -1,2)
Step-by-step explanation:
A =(b1+b2)h/2
actual b1 =10cm*10m/1cm =100m
actual b2 = 6cm*10m/1 cm = 60m
height = 5 cm*10m/1cm = 50m
A=(100+60)*50/2 = 160*50/2 =80*50= 4,000 m²
Answer : <span>C.=4,000 m²</span>
