Answer:
x= 4 y= -1
Step-by-step explanation:
if you multiply -3 by 4 it equals -12 then add -1 to get - 13 for the first equation.
for the second equation you multiply 3 by 4 to get 12 and multiply 4 by -1 to get -4 then you add them together to get 8. start with a process of elimination by substituting each eqation with 0.
Answer:
-.8
Step-by-step explanation:
divide both sides by 2.8
3d-2=-4.4
add two to both sides
3d=-2.4
divide both sides by 3
d=-.8
Step-by-step explanation:
the answer would be -9.
28x -63 = -315
add 63 to -63 and -315
there u get this
28x= -252
then divide 28 both sides
x=-9
Answer:
f(x) = 3.7x + 3
Step-by-step explanation:
Using the fact that y = f(x), then rearrange the equation making y the subject.
- 3.7x = 3 - y ( add y to both sides )
y - 3.7x = 3 ( add 3.7x to both sides )
y = 3.7x + 3 , that is
f(x) = 3.7x + 3
