How do I solve this?
ladessa [460]
It would be 
y=(-16*-1)
which would then be 
y=16
so the answer would be
(-16,16)
you replace the x in the equation with the x you are given

Guys help me with a) and b) tasks<br>ANSWER:<br>a) 40<br>b) 25<br>Thanks&lt;3​
umka21 [38]

Step-by-step explanation:

there are 2 similar triangles : ABE and DCE

that means they have the same angles, and the scaling factor from one triangle to the other is the same for every side.

and that means that

DE/AE = EC/BE (= DC/AB)

we know that

AE = AD + DE

BE = BC + EC

a.

so, we have actually

DE/(AD+DE) = EC/(BC+EC)

DE/(10+DE) = 8/(2+8) = 8/10 = 4/5

DE = 4(10+DE)/5

5DE = 4(10+DE) = 40 + 4DE

DE = 40 cm

b.

AD/DE = 3/5

BC/EC must be 3/5 too.

15/EC = 3/5

15 = 3EC/5

75 = 3EC

EC = 25 cm
