9. sensitive noses, big ears, and long tail.
10. ferns, yeasts, hydras, and amoebas
Answer:
x=3
Step-by-step explanation:
6 10
---------- = ------------
6+x 15
using cross products
6 * 15 = 10 * (6+x)
90 = 60+10x
subtract 60 from each side
90-60 = 60+10x-60
30 = 10x
divide by 10
30/10 = 10x/10
3=x
Step-by-step explanation:
2x3(3+1)x4+7-5
6(4)x4+2
24x4+2
96+2
98
hope this helps you
have a good day
We have the first equation:
-10x + 5y = zero
we can divide all terms by 5 to get:
-2x + y = zero
This means that:
y = 2x .................> equation I
We now will look at the second equation:
<span>-4x-6y=54
</span>we will substitute with equation I in this equation to get:
<span>-4x-6(2x)=54
-4x - 12x = 54
-16x = 54
x = -3.375
Substitute with the value of x in equation I to get y as follows:
y = 2(3.375) = -6.75
Therefore, for the given system of equations:
x = -3.375
y = -6.75</span>
Answer:
y = - 1/5x +8
