Use the substitution method to solve the system of equations. choose the correct ordered pair. y = 5x + 7 x = 8 a. (8, 47) b. (0, 7) c. (8, 15) d. (0, 8)

Assuming the system is composed of the equations y = 5x+7 and x = 8, then the answer is (8,47) which is choice A

To get this answer, we simply replace x in the first equation with 8, and then compute

y = 5x+7

y = 5*8+7 replace x with 8

y = 40+7

y = 47

So together x = 8 and y = 47 pair up to get us the solution (x,y) = (8,47)

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.

answer: no, but if it does it's a obvious pattern.
