Y = 3/2x + b
-1 = 3/2(4) + b substitute the point (4, -1) for x and y.
-1 = 6 + b
-7 = b
b = -7
Answer:
Step-by-step explanation:
midpoint : the midpoint of a segment is a point that divide the segment into two congruent segments ( equal)
congruent segments: are segments that ave the same length, the points on the segment are col-linear.
M is the midpoint of AB: Given
this means that AM=MB : M is the midpoint of AB that divide the segment into two equal parts
Therefore AM=MB : congruent segments.
Answer:
adults : 0 children: 600
Step-by-step explanation:
x + y = 600
6x+4y = 2400
4×(x + y = 600) = 4x+4y = 2400
(6x+4y = 2400) - (4x+4y = 2400) = x=0
so y=600
Answer:
<em>2a</em>
Step-by-step explanation:
Look at the numbers first: 12, 28, 42
12 = 2 * 2 * 3
28 = 2 * 2 * 7
42 = 2 * 3 * 7
The only factor all numbers have in common is 2.
GCF of numbers = 2
Now look at the variables: a^2b^6, a^4, ab^3
a^2b^6 = aabbbbbb
a^4 = aaaa
ab^3 = abbb
The only variable all expressions have in common is a.
GCF of variables = a
GCF of the three monomials is: 2a
Answer:
30
Step-by-step explanation:
To find the answer you would need to do 2400 divided by 80 which = 30
Hope this helped :)
