Answer:
<h2>
the first ordered pair is (-2, -2)</h2><h2>
the second ordered pair is (4,0)</h2>
Step-by-step explanation:
to find the missing values, plug in the given values into the equation:
x-3y=4
the first ordered pair:
we are given a y-value (-2), so lets plug it into the equation:
x-3*(-2)=4
now solve for the missing value:
x+6=4
x=4-6
x=-2
now plug in both x and y and check if the equation is true:
(-2)-3*(-2)=4
-2+6=4
6-2=4
4=4
the first ordered pair is (-2, -2)
the second ordered pair:
we are given a x-value (4), so lets plug it into the equation:
(4)-3y=4
now solve for the missing value:
-3y=4-4
-3y=0
y=0/-3
y=0
now plug in both x and y and check if the equation is true:
(4)-3*(0)=4
4-0=4
4=4
the second ordered pair is (4,0)
Hey! this is your answer...y=2 over x +4
A represents the speed of the aircraft.
b represents the speed of the bus.
a=2b-5
114/b=218/a
Substitution method
114/b=218/(2b-5)
(2b-5)*(114/b)= 218
(228b-570)/b = 218
228b-570= 218b
228b-218b=570
10b= 570
b=57
Plug the value of b into one of the original equations.
a=2(57)-5
a=114-5
a=109
Final answer:
Average speed of plane= 109
Average speed of bus= 57
We will use factor to calculate zero of the eq. Then putting the value of zero in place of x we can get the value of n.plz see pic for complete solution
1/2 (14x-2)-1/4(4x-24) = 6x + 5
