rewona [7]

Answer:

Step-by-step explanation:

Given that,pros.

lpsa = 1.507 + 0.719 lcavol

lpsa=0.719 lcavol + 1.507

Comparing this to equation of a straight line, y=mx+c

Then,

slope (m) = 0.719

And intercept (c) on y axis is 1.507

Then, the x axis is lcavol

Also, the y axis is lpsa.

Then the linear model preview is

Answer:

Step-by-step explanation:

To start off this problem, we are given that the line AB is equal to the line CD. In addition to that, we are given that the line EF equally intersects line AB and line CD. This provides us proof that angle AGH is equivalent to angle DHG. From this information, we can solve this problem relatively easily.

Lets work with this equation:

$80 = 5x$

Next, divide 80 by 5.

$\frac{80}{5} =x$

$16 = x$

This means that x is equal to 16.

Write an equasion of the line in point-slope form that passes through the points (-16, 8) (4,2)

xeze [42]

You start by finding the slope : y2 - y1 / x2 - x1

2 - 8 / 4 - (-16)

- 6 / 20

m = - 3 / 10

Point slope form : y - y1 = m( x- x1 )

You can pick either of the coordinates and substitute them in

POINT SLOPE FORM EQUATION : y - 8 = -3/10 ( x + 16 )

What is the answer

Igoryamba

Answer:

∠B = 60°

Step-by-step explanation:

They are supplementary angles, which means they add up to 180°.

∠B + ∠A = 180

? + 120 = 180

? = 180 - 120

? = 60°
