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

For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 63 N acts on

Luba_88 [7]

Answer:

18 N

Step-by-step explanation:

Let <em>F</em> denote the force, <em>m</em> denote the mass of the object and <em>a </em>denote the acceleration of the object.

<em /> $F=ma$ <em />

$m = \frac{F_{1} }{a_{1} }=\frac{63}{7} =9 kg$

$F_{2} =ma_{2}=9*2=18N$
