1: Khi m=4 thì (2): \(y=4\cdot x+4-1=4x+3\)

Bảng giá trị:

Vẽ đồ thị:

2: Thay y=0 vào y=x+3, ta được:

x+3=0

=>x=0-3

=>x=-3

Thay x=-3 và y=0 vào y=mx+m-1, ta được:

\(-3m+m-1=0\)

=>\(-2m-1=0\)

=>\(2m+1=0\)

=>2m=-1

=>\(m=-\dfrac{1}{2}\)

a) Khi m = 4

(2) ⇔ y = 4x + 3

Đồ thị:

b) Điểm nằm trên trục hoành thì có tung độ bằng 0

Thay y = 0 vào (1) ta có:

x + 3 = 0

⇔ x = -3

Thay x = -3; y = 0 vào (2) ta có:

⇔ -3m + m - 1 = 0

⇔ -2m = 1

⇔ m = -1/2

Vậy m = -1/2 thì đồ thị của (1) cắt đồ thị của (2) tại một điểm trên trục hoành

\(a,x\times4+x\times36=80\\ \Leftrightarrow x\times\left(4+36\right)=80\\ \Leftrightarrow x\times40=80\\ \Leftrightarrow x=80:40\\ \Leftrightarrow x=4\)

Vậy \(x=4\)

\(b,x\times\dfrac{1}{8}+x\times\dfrac{7}{8}=11,375-1,375\\ \Leftrightarrow x\left(\dfrac{1}{8}+\dfrac{7}{8}\right)=10\\ \Leftrightarrow\dfrac{8}{8}x=10\\ \Leftrightarrow x=10\)

Vậy \(x=10\)
