4 0

Answer:

(0,-3)

Step-by-step explanation:

hi, with this we can just do substitution (substitute x for y+3)

6(y+3)-5y=15

evaluate

6y+18-5y=15

y+18=15

y=-3

then we plug that in

x=-3+3

x=0

V=u+at u=2 a=15 t=1/5 what is the value of v
alukav5142 [94]

Answer and explanation:

V originally equals u + at, but when you plug in u, a, and t you get a number answer.

u = 2

a = 15

t = 1/5

Rewrite the expression with the numbers plugged in.

V = (2) + (15)(1/5)  <em>Multiply 15 by 1/5</em>

V = 2 + 3  <em>Add 2 and 3 together</em>

V = 5

<h2><u>So V would equal 5</u></h2>

Are obtuse angles always, sometimes, or never equal to 180°? .always .sometimes .never
laila [671]
Salutations!

<span>Are obtuse angles always, sometimes, or never equal to 180°?

Obtuse angles are angles </span>whose measure is greater than 90° and less than 180°. Its not always the case that an obtuse angle should be exact 180 °. So I reckon t would be sometimes, as its not always 180 °. 

Hope I helped.
