Answer:

AD cuts BC at I => I is the midpoint of BC => BI = CI

ΔAIB and ΔAIC have:

AB = AC

BI = CI

m∠ABC = m∠ACB ( because ΔABC is a isosceles triangle)

=> ΔAIB ≅ ΔAIC (sas)

=> m∠BAD = m∠CAD

ΔADB and ΔADC have:

m∠BAD = m∠CAD

AB = AC

AD is the common edge

=> ΔADB ≅ ΔADC (sas)

Write an equation of the line below

Ratling [72]

Answer:

y = 3/5 + 4

Step-by-step explanation:

Given Coordiantes:

(0,4) - Y-intercept

(5,7) - Coordinates

To make an equation, first find the slope.

$m=\frac{rise}{run} =\frac{y}{x}$

$m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }$

$m=\frac{7-4}{5-0}$

$m=\frac{3}{5}$

In decimals:

$m = 0.6$

Now convert to point slope.

$y-y_{1} =m(x-x_{1} )$

$y-4=\frac{3}{5} (x-0)$

In decimals:

$y-4=0.6(x-0)$

Now convert to slope-intercept form.

Find the Equation of the Line:

$y=mx+b$

by solving for y using the Point Slope Equation.

y = 3/5 + 4

Oliver is determining the number of males in his math class. Oliver is collecting what kind of data? A) bivariate B) categorical

Svet_ta [14]

When Oliver is considering the number of males, he typically assigns people to two categories: make or female, which makes the variable bi-variate : with two values.("bi" means "two).

If he's more inclusive, and adds the category of "other", it would be a categorical data - with 3 categories.

Y = 3 + 1/5x y = -7x-9 y = 11 - 3x

Varvara68 [4.7K]

Answer:

1. x = 15

2. x = - 9/7

3. x = 11/3

Step-by-step explanation:

Part one, y = 3+1/5x

to find x-intercept/zero, substitute y= 0

0 = 3 + 1/5

multiple both sides of the equation by five.

0 = 15 + x

move the variable to the left.

-x=15

change the signs on both of the equations.

x = -15

your solution is x = -15.

Part two, y = -7x -9

Move variable to the left hand side and change its sign.

7x = -9

Divide both sides of the equation by 7.

x=-9/7

Solution is x = - 9/7

Part three, y= 11 -3x

to find x intercept y and substitute for zero.

0= 11 - 3x

move variable to the left hand side and change its sign.

3x= 11

divide both sides by 3.

x= 11/3

Solution is x = 11/3
