Let a, b, c, and d be real numbers with a, c 6= 0. Prove that the lines y = ax+b and y = cx + d have the same x-intercept if and
Monica [59]

Step-by-step explanation:

We have got the lines :

y=ax+b\\y=cx+d

Both lines intercept the x-axis in the point :

I = (i_{1} ,i_{2})

In all point from x-axis the y-component is equal to 0.

I=(i_{1},o)

We replace the I point in the lines equations:

0=a(i_{1})+b \\0=c(i_{1})+d

From the first equation :

0=a(i_{1})+b \\-b=a(i_{1})\\i_{1}=\frac{-b}{a}

From the second equation :

0=c(i_{1})+d\\ -d=c(i_{1})\\i_{1}=\frac{-d}{c}

Then i_{1}=i_{1}

Finally :

\frac{-b}{a}=\frac{-d}{c} \\\frac{b}{a}=\frac{d}{c} \\ad=bc

y = ax + b and y = cx + d have the same x-intercept ⇔ad=bc

The measure of an angle is 167°. What is the measure of its supplementary angle?
Anna007 [38]

Answer:

x=13

Step-by-step explanation:

Supplementary angles add to 180 degrees

x+167 = 180

Subtract 167 from each side

x+167-167= 180-167

x = 13

How do I simplify 6y-y
aniked [119]
Think of 6y as

y + y + y + y + y + y

Now subtract a y from that.

y + y + y + y + y + y - y = y + y + y + y + y = 5y
