Answer:
n + p = m
Step-by-step explanation:
x(the unnamed angle) and m both equal 180
x + m = 180
x + n + p =180
180 = 180
x + m = x + n + p
m = n + p
Answer:
WELL SHE SHOULDN'T BE SURPRISED BECAUSE THE CEREAL COMPANY SAID each of the 5 cards ARE equally likely to appear in any box of cereal. THAN YOU COULD HAVE GOT MORE THAN ONE CARD OF THE SAME PERSON SO YOU SHOULDN'T BE SURPRISED BECAUSE ITS WOULD BE HARD TO GET ALL THE FIVE PLAYERS IN THE FIRST FIVE CEREAL BOXES YOU BUY SO SHE SHOULDN'T BE SURPRISED
Step-by-step explanation:
The equation would be 12x+85=y
x= # of people
y= Total amount of money
Edit: I did #4 sorry
Answer:
Step-by-step explanation:
This is a horizontal parabola opening to the right, with vertex at (-2,0) and directrix at x = -4 (which is to the left of the vertex). The general equation of such a parabola is 4p(x-h) = (y-k)^2, where p is the number of horizontal units between directrix and vertex; here this quantity is 2.
Substituting known values into the general equation, we get:
4(2)(x+2) = (y-0)^2, or 8(x+2) = y^2.
Check: does (-2,0) satisfy the above equation (as it must)? 8(-2+2) = 0^2 YES.
It must be less than 90 because acute triangles have angle under 90
