The equation of line t is y = -2x + 9. Perpendicular to line t is line u, which passes through
Archy [21]

Answer:

Equation of line u in slope-intercept form is: \mathbf{y=\frac{1}{2}x+9 }

Step-by-step explanation:

Equation of line t : y = -2x + 9.

We need to find equation of line u, which is perpendicular to line t and passes through point (-10,4)

The equation must be in slope-intercept form.

The general equation of slope-intercept form is: y=mx+b where m is slope and b is y-intercept

Finding Slope:

If two lines are perpendicular, their slopes are opposite i.e m=-\frac{1}{m}

Slope of line t: y=-2x+9 we get m =-2 (Comparing with general form y=mx+b, we get m =-2)

Slope of line u: \frac{1}{2}

So, we get Slope of line u: m= \frac{1}{2}

Finding y-intercept:

Using slope m= \frac{1}{2} and point(-10,4) we can find y-intercept

y=mx+b\\4=\frac{1}{2}(-10)+b\\4=-5+b\\b=4+5\\b=9

Equation of line u:

So, equation of line u, having slope m= \frac{1}{2} and y-intercept b=9, we get:

y=mx+b\\y=\frac{1}{2}x+9

So, Equation of line u in slope-intercept form is: \mathbf{y=\frac{1}{2}x+9 }

Which value for x completes the conditional relative frequency table by column?
zheka24 [161]

<u>Answer-</u>

In the conditional relative frequency table by column, the value of x is 0.85

<u>Solution-</u>

From the paint color preference table,

Liked new paint color + Disliked new paint color = 1

\Rightarrow x+0.15 = 1

\Rightarrow x=1-0.15

\Rightarrow x=0.85

Therefore, we have x=0.85 or 85% of adults who like the new color of the paint.
