If the function y = 3x + 2 is translated 5 units up, which equation will best describe the new line?

1 answer:

4 0

Y=3x+7
this equation is in slope- intercept form (y=mx+b), so to translate up or down you add or subtract however many units you are translating to the b of the equation.

What is the y-coordinate of the point that divides the directed line segment from J to K into a ratio of 5:1? y = (StartFraction

Dominik [7]

By applying section formula we got that y-coordinate of the point that divides the directed line segment from J to K into a ratio of 5:1 is $\frac{5y_2+y_1}{6}$

<h3>What is section formula ?</h3>

Let point P(x,y) cuts line joining point $A(x_1,y_1)$ and $B(x_2,y_2)$ in $m_1:m_2$ then coordinate of point P is equal to $(\frac{m_1x_2+m_2x_1}{m_1+m_2}, \frac{m_1y_2+m_2y_1}{m_1+m_2})$

Here given that point divides line segment from J to K into a ratio 5:1

$m_1=5\\\\m_2=1$

Now we have to fin y coordinate of point that divides the directed line segment from J to K into a ratio of 5:1

We can calculated y coordinate by applying section formula as :

$\frac{5y_2+1y_1}{5+1}\\\\\frac{5y_2+y_1}{6}$

By applying section formula we got that y-coordinate of the point that divides the directed line segment from J to K into a ratio of 5:1 is $\frac{5y_2+y_1}{6}$

What is 2.5x10^2? What is the exponent in 10^2?

Pachacha [2.7K]

Answer:

The exponent is 2

Step-by-step explanation:

2.5 x 10²

I mean you said it yourself, the exponent is the number above the ten meaning it is raised to that value.

So 2 is the exponent.
