Answer:

B.) -16

Step-by-step explanation:

-10=-2+1/2d

-8=1/2d

d=-8/1/2

d=-16

So B

In triangle XYZ, the length of side XY is 26 mm and the length of side YZ is 37 mm. Which of the following could be the length o
mario62 [17]
Remember that to be a triangle, one side must be smaller than the sum of the other two sides or else it will be a line
so if x=largest side then the other sides are y and z then
y+z>x so

we have side XY=26 and YZ=37
37 could be the shorter side or
these are the shorter sides

if 37 is the shorter side then go to AAAAAAAAAA
if these are the shorter side then go to BBBBBBBBBBBBBBB
BBBBBBBBBBBBBBBBB


AAAAAAAAAAAAAAAAAAAAAAA
26+XZ>37
subtract 26 from both sides
XZ>9
therefor the answer could be any number greater than 9 so the answer is A,B,D

BBBBBBBBBBBBBBBBBB
26+37>XZ
add
63>XZ
therefor the answer could be 65 or 68 (A and D)

100 points Triangle ABC is shown below: Triangle ABC is shown. A is at 2, 1. B is at negative 1, 4. C is at 3, 7. If triangle AB
Vinil7 [7]

Using translation concepts, the coordinates for point C' are given as follows:

C'(-3,7).

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

The rule for a reflection over the y-axis is given as follows:

(x,y) -> (-x,y).

Hence, for point C', the coordinates are given by:

(3,7) -> (-3,7).

What are the coordinates of point B on AC such that AB
sweet [91]

Answer: The mid-point of AC easy to calculate.

It is at ((5+3)/2,(5−1)/2)=(4,2) .

What you really asked was the coordinates of the point 3/4 of the way from A to C, and the calculation is very similar. I think of it as giving a “weighting” to the nearest point. So in this case we give a weighting of 3 to point C and 1 to point A.

Then =((5+3∗3)/4,(5−1∗3)/4)

So =(3½,½) .

CHECK:

Distance

2=(5−3½)2+(5−½)2

=(3/2)2+(9/2)2=9/4+81/4

=90/4

So the distance =310‾‾‾√/2

And the distance

2=(3½−3)2+(½+1)2

=1/4+9/4=10/4

And so the distance BC is 10‾‾‾√/2 which is indeed one third of the distance AB.

Determine which set of side measurements could be used to form a right triangle.
musickatia [10]

The set of side measurements that could be used to form a right triangle is 3, 4 and 5 option (D) is correct.

What is a right-angle triangle?

It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.

It is given that:

The side length of the triangle is shown in the option:

As we know,

Pythagoras' theorem is the square of the hypotenuse in a right-angled triangle is equal to the sum of the squares of the other two sides.

Using Pythagoras' theorem:

From option(D):

3, 4 and 5

(3)² + (4)² = 5²

9 + 16 = 25 (True)

Thus, the set of side measurements that could be used to form a right triangle is 3, 4 and 5 option (D) is correct.
