How many solutions does the system have?<br> y=-2x -4 <br> y=3x + 3
baherus [9]

Answer:

x=−7/5and y=−6/5

Step-by-step explanation:

Step: Substitute−2x−4foryiny=3x+3:

y=3x+3

−2x−4=3x+3

−2x−4+−3x=3x+3+−3x(Add -3x to both sides)

−5x−4=3

−5x−4+4=3+4(Add 4 to both sides)

−5x=7

−5x

−5

=

7

−5

(Divide both sides by -5)

x=−7/5

Q # 8 please helme to resolve
kondor19780726 [428]

Sequence 1,5,9,13,...

A(0) = 1 +4x0=1

A(1) =1 + 4x1 = 5

A(2) = 1+ 4x2= 9

A(3) = 1 +4x3=13

A(n)= 1+4n   A(n-1) = 1+4(n-1) =1+4n-4= - 3+4n

A(n) - A(n-1) = (1+4n) - (-3=4n) = 4

A(n) = A(n-1) +4; 29 is the answer
