Answer:

Since you don't show your triangles, I'm guessing it is this one...?

△DWP D = (-2, 4), W = (-1, 2), P = (3, 3)

△MJS M = (-4, -4), J = (-2, -3), S = (-3, 1)

There are 2 steps:

1. 90° counterclockwise rotation about the origin

2. Translation downward 2 units

Step-by-step explanation:

1. 90° counterclockwise rotation about the origin = (x, y) to (-y, x),

D moves from (-2, 4) to (-4, -2)

W moves from (-1, 2) to (-2, -1)

P moves from (3, 3) to (-3, 3)

2. Translation downward 2 units = (x, y) to (x, y-2),

D moves from (-4, -2) to (-4, -4) = M

W moves from (-2, -1) to (-2, -3) = J

P moves from (-3, 3) to (-3, 1) = S

Therefore △DWP IS congruent to △MJS.

Answer:

Step-by-step explanation:

So what you need to do is take the two points (1, -5) and (3, -1) and subtract them. You take y of the second group and subtract y of the first group.

-1 - (-5) = 4

Now you do the first numbers in each group with the second set being the number you subtract from.

3 - 1 = 2

Now you do $\frac{Rise}{Run}$ . Rise = 4 Run = 2

$\frac{4}{2}$ = 2

Now the second part is saying y = 3x + c with your first set of numbers being x and y.

x = 1

y = -5

-5 = 3(1) + c

-5 = 3 + c

Subtract 3 from -5

-8 = c

The final answer is:

y = 3x - 8

$Question$

Alice skates 2/5 mile in 1/5 hour. Elizabeth skates 2/3 mile in 2/9 hour. How far did elisabeth escape in in 1 hour?

Answer:

The Correct Answer is $\frac{8}{9}$

Complete the multiplication and the equation becomes

$\frac{2}{9}$ + $\frac{2}{3}$ = ?

The two fractions now have like denominators so you can add the numerators.

$\frac{2+6}{9}$ = $\frac{8}{9}$

Therefore, The Answer Is $\frac{8}{9}$

Hope this helps!

Jennifer is calculating her gpa. if she uses "=(a1+a2+a3+a4)/4", this is an example of which type of entry?

ArbitrLikvidat [17]

The first thing we should know in this case is the meaning of the following acronyms:
(GPA) = Grade Point Average.
Effectively in a program like excel she can use:
GPA = (a1 + a2 + a3 + a4) / 4
Where,
ai = represents each of the notes (i: 1,2,3,4)
However, this is also an example of the following type of entry:
GPA = AVERAGE (a1: a4)
Answer:
Entry:
Formulas: are references of cells, names of cells or ranges, functions or operators that result in a value from other existing values.

To buy a truck you can pay $13,000 cash or put down $4250 and make 24 monthly payments of $595.54. How much would you save by pa

-Dominant- [34]

Savings by paying cash is $1,289.6.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

To buy a truck cash payment = $13,000

And, Put down cash = $4250

Now, Calculate the total amount with payments;

Total amount with payment = Payment amount * Total month

= $595.54 * 24

= $14,289.6

And, Calculate the total amount saved by paying cash;

Savings by paying cash = Total amount with payments - Cash payment

= $14,289.6 - $13,000

= $1,289.6

Hence, Savings by paying cash is $1,289.6.
