Ok firstly convert the first equation into the understandable form.
y = -2x +3

Next draw a dot on the y-ax at the height of +3 (3 is c in (y = ax + c) and c is always the intersection with the y-ax).

Next substitute y with 0,
0 = -2x + 3
<=> x = 3/2
Draw a dot on the x-ax at x=3/2 or 1.5.
Connect the two dots and you have the first function.

Now do the same thing for the second equation and read the coordinates from the intersection of the two equations.

That’s it!

Triangle CAT is transformed to produce triangle DOG.

PilotLPTM [1.2K]

Using transformations and congruency concepts, it is found that with these following transformations, the triangles will be congruent.

A reflection, then a translation.
A rotation, then a reflection.

--------------------------

Two triangles are congruent if they have the same lengths of the sides and the same angles.

In a reflection, there is a rule that changes the coordinates (x,y), but does not change the lengths of the sides of the triangles, thus they will still be congruent.
A reflection is also a special case of rotation, thus, in a rotation, the triangles are also congruent.
A translation is also similar to a reflection, using rules to shift the triangle up, down, left or right according to it's coordinates, not changing the sides or angles, thus congruent.
In a dilation, the lengths of the sides are changed, thus, the triangles will not be congruent.

--------------------------

Thus, from the bullet points above, the correct options are:

A reflection, then a translation.
A rotation, then a reflection.

Winne is currently considering two plans for paying for piano lessons.

SVEN [57.7K]

Answer:

Plan B

Step-by-step explanation:'

First u have to divide each one to see how much each piano lesson costs.

Plan A- 31.50/6=5.25

Plan B- 20.60/4=5.15

So since Plan B is less then Plan B would be the answer.

Which is the solution set of the inequality 15y-9<36

m_a_m_a [10]

15y - 9 <36.
Add 9 to each side.

15y- 9 (+9) < 36 + 9.
15y < 45.
y < 3.
Hope it helps! :)
