M + w + c = 2838
w = 3c + 5
m = 4w - 3......4(3c + 5)- 3 = 12c + 20 - 3 = 12c + 17
(12c + 17) + (3c + 5) + c = 2838 .....combine like terms
16c + 22 = 2838
16c = 2838 - 22
16c = 2816
c = 2816/16
c = 176 <==== children
w = 3c + 5
w = 3(176) + 5
w = 533 <=== women
m = 12c + 17
m = 12(176) + 17
m = 2129 <=== men
Answer:
Step-by-step explanation:
y = x² + x - 3
x = - 3
y = ( - 3 )² + ( - 3 ) - 3 = 3
( - 3 , <em>3</em> )
x = 0 ⇒ y = - 3
( 0 , <em>- 3</em> )
x = 1
y = ( 1 )² + ( 1 ) - 3 = - 1
( 1 , <em>- 1 </em>)
<em>(b).</em> Coordinate x of the vertex of quadratic equation y = ax² + bx + c is
- 
x = - 
= - 
= - 0.5
y = ( - 0.5 )² + ( - 0.5 ) - 3 = - 3.25 = - 3
( - , - 3 )
Answer:
8 baskets worth 3 points each and 4 baskets worth 2 points each
Step-by-step explanation:
It is 8 baskets worth 3 points each and 4 baskets worth 2 points each because it says Juarez scored twice as many baskets worth 3 points than the baskets worth 2 points. 4 x 2 = 8
-----------------------------------------------------------------------------
6 baskets worth 3 points each and 7 baskets worth 2 points each
: wrong because 7 x 2 = 14.
10 baskets worth 3 points each and 1 basket worth 2 points
: wrong because 1 x 2 = 2.
4 baskets worth 3 points each and 10 baskets worth 2 points each: wrong because 10 x 2 = 40.
