Question

Solve the system using the substitution method. Show your work. Check your solution.
4y + 2x = 48
x = –2y + 26

Answer 1

in substitution method we substitue value of any variable in terms of another

here.. 4y + 2x = 48
2x = 48 - 4y
x = (48 - 4y)/2

we substitue this value of x in second eqn

Answer 2

wait but we havents found x

Answer 3

x=11

Answer 4

show ur work..n pls check the qstn once...i guess sumthng is wrong

Answer 5

no solution!

Answer 6

i did it wrong?

Answer 7

yes ... i am also getting no solution

Answer 8

my tutor said it might not have a solution so we are right!

Answer 9

for this pair of eqn there is no solution ...iam 100 % sure

Answer 10

we are right then! THANK YOU !

Answer 11

welcome..any other questions

Answer 12

yes Line A goes through the points (4, 0) and (–2, 18). Line B goes through the points
(0, –5) and (2, –11). Are the two lines parallel, perpendicular, or neither?

Answer 13

i got neither

Answer 14

find the slope of both the lines
for line A slope is -3 and for line B slope is also -3

so both the lines are parallel

Answer 15

because they have the same slope ?

Answer 16

yes m1 = m2 then parallel and when m1m2 + -1 en perpndclr

Answer 17

its perpendicular when they are opposites?

Answer 18

no perpendicular when m1m2 = -1 or m1 = -1/m2

Answer 19

if its a horizontal line the slope is 0 right?

Answer 20

because there is no rise over run

Answer 21

yes

Answer 22

i have one more question if you would like to go through it with me

Answer 23

im reviewing for a test

Answer 24

yes sure...

Answer 25

Solve the system of equations by addition method. Show your work. Check your solution.
3𝑎+2𝑏=11
7𝑎−3𝑏= −5

Answer 26

i dont know if those are zeros or boxes
