The line equation is given by
where <em>m </em>is the slope and <em>b </em>is the interception with <em>Y-axis</em>
Answer:
-5.02
Step-by-step explanation:
the result becomes negative because 7.273 is less than 12.37
Boys are b
Girls are g
b + g = 120
2g = b
Substitute the second equation into the first
2g + g = 120
3g = 120
g = 40
Plug in g = 40 and solve for b
b + g = 40
b + 40 = 120
b = 80
There are 40 girls and 80 boys.
Answer:
a) h = 6 2/17
b) k = 3 8/17
Step-by-step explanation:
We can make a list of corresponding sides:
AB (17 cm) and DE (13 cm)
BC (15 cm) and EC (8+k cm)
CA (8 cm) and CD (h cm)
Because the triangles are similar, we know corresponding sides are proportional.
<h3>a)</h3>
CD/CA = DE/AB
h/8 = 13/17
h = 8(13/17) = 6 2/17
__
<h3>b)</h3>
EC/BC = DE/AB
(8+k)/15 = 13/17
8 +k = 15(13/17)
k = 11 8/17 -8 = 3 8/17
