Answer:
a = 7.4
b = 9.6
Step-by-step explanation:
set up a proportion to find 'b':
XN / NY = MN / NO
8/b = 13/(b+6)
cross-multiply:
13b = 8(b+6)
13b = 8b + 48
5b = 48
b = 9.6
set up a proportion to find 'a':
XN / XY = MN / MO
8/a = 13/12
cross-multiply:
13a = 96
a ≈ 7.4
Answer:
The first stpe in solving this system of equations is finding either X or Y in terms of the other variable. Ex: x = 8 - y or y = 8 - x
Step-by-step explanation:
When faced with a system of equations problem, you need to find one variable at a time. To do this, you need to eliminate one of the variables from one of the equations. I used x + y = 8 because that was simplier to find one of the variables from. From there, you can substitute that in for the variabel in the secone equation.
3x - 2y = -6
3x - 2(8 - x) = -6
3x - 16 + 2x = -6
5x - 16 = -6
5x = 10
x = 2
Than you can use that and plug it back into one of the original equations to find the other variable.
x + y = 8
2 + y = 8
y = 6
Answer:
x= 8.1353
x= 8.135 (rounded to the nearest tenth-thousandths)
x= 8.14 (rounded to the nearest thousandths)
x= 8.1 (rounded to the nearest tenth)
Step-by-step explanation:
<u><em>Note I am not 100% sure with my answer</em></u>
2 − ln (x − 8)= 4
−ln (x − 8) + 2= 4
−ln (x − 8) + 2 + −2= 4 + −2
−ln (x − 8)= 2
−ln (x − 8)/−1= 2/−1
ln (x − 8)= −2
<solve for the logarithm (ln)>
ln (x − 8)= −2
e^ln (x − 8)= e^−2
x − 8= e^−2
x − 8= 0.1353
x − 8 + 8= 0.1353 + 8
x= 8.1353
