Scalene right triangle-

None of the angles are congruent so it’s scalene, but since a it has a 90 degree angle it is also a right triangle

On a coordinate plane, point A is located at (7, 4), and point B is located at (-8, 4). What is the distance between the two poi

wel

Answer:

Solution given;

A(x1,y1)=(7,4)

B(x2,y2)=(-8,4)

distance AB=?

we have

d= $\sqrt{(x2-x1) ²+(y2-y1) ²}$

AB= $\sqrt{(-8-7)²+(4-4)²}$

AB=15 units

the distance between the two points is 15 units.

I wrote the domain and range in interval notation, not sure if that’s how you’re asked to do it. This is how I was taught to state the domain/range of a graph.

A line passes through the points (–1, –5) and (4, 5). The point (a, 1) is also on the line.

IgorC [24]

Answer:

a = 2

Step-by-step explanation:

Let's find the equation of the line using the 2 points given.

Let's call -1 as x_1 and -5 as y_1

also, 4 as x_2 and 5 as y_2

The equation of line is :

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

<em>Let's plug the points and get the equation of the line:</em>

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\y+5=\frac{5+5}{4+1}(x+1)\\y+5=2(x+1)\\y+5=2x+2\\y=2x-3$

Now, to find a, we substitute a in x and 1 in y of the equation of the line we just got:

$y=2x-3\\1=2(a)-3\\1=2a-3\\2a=4\\a=\frac{4}{2}=2$

Answer:

1. The right triangles pass the AA similarity congruence theorem.

2. s/q

Step-by-step explanation:

They are similar since they pass the AA( Angle-Angle) similarity theorem.

Similar triangles have corresponding proportional sides so side z corresponds with side s and side x corresponds with q so we would represent that as

s/q
