What are the coordinates of D' after its preimage, D(4, -8), is reflected over the line y = x?
olya-2409 [2.1K]

Answer: D' is (-8,4)

Step-by-step explanation: The rule for reflection y=x is (x,y)>( y,x) So when  relecting over the axis y=x the x cordinate and the y cordinate switch places.

Justify each step. <br> x/3-7=11 <br> x/3=18<br> x=6
Nina [5.8K]
This is the steps for equation solving for the value of x,
x/3-7 = 11
now 7 goes to the other side of equation by changing the sign from - to +,
x/3 = 11 + 7
x/3 = 18
now when we multiply both sides of equation with 3 or 3 goes to the other side of equation and multiply with 18 leaving x alone here for finding the value of x,
and we get, x = 54
at the end of equation we get x = 54, if the equation was in the form 3x - 7 = 11, then we will get x = 6

In in the previous activity you solved a system of equations representing the carnival admissions using the elimination method i
Mariulka [41]

Answer:

The value of a=300 and value of k=200

If you solve the above system of equations by elimination method, you will get the same values of a and k.

In Equation 1 k+a=500 both variables k has 1 as their coefficient.

Step-by-step explanation:

We need to solve the system of equations using substitution method

The equation are:

k + a = 500--eq(1)\\3k + 10a = 3,600 --eq(2)

For substitution method, we find value of k from equation 1 and put in equation 2

From \ eq(1) \ we \ get\\k=500-a

Putting it in eq(2)

3k+10a=3600\\Put \ k=500-a\\3(500-a)+10a=3600\\1500-3a+10a=3600\\7a=3600-1500\\7a=2100\\a=\frac{2100}{7}\\a=300

So, we get value of a = 300

Now finding value of k by putting value of a in equation k=500-a

k=500-a\\Putting \ a \ =500\\k=500-300\\k=200

So, we get value of k =200

The value of a=300 and value of k=200

If you solve the above system of equations by elimination method, you will get the same values of a and k.

In Equation 1 k+a=500 both variables k has 1 as their coefficient.
