Shape A can be transformed to shape B by a reflection in the x-axis followed by a translation (c/d). Find the value of c and the
bagirrra123 [75]

Answer:

c = -6

d = -1

Step-by-step explanation:

Given

See attachment for grid

Required

Find c and d

From the attachment, we have:

a = (3,5) --- Point on A

a' = (-3,-6) --- Corresponding point on B

When A is reflected across the x-axis, the rule is:

(x,y) \to (x,-y)

So, we have:

(3,5) \to (3,-5)

Next, is to calculate the translation from (3,-5) to (-3,-6)

This is calculated using:

3 + c = -3

and

-5 + d = -6

So, we have:

3 + c = -3

c = -3-3

---- i.e. Shift by 6 units to the left

-5 + d = -6

d = 5 - 6

d = -1  --- i.e. Shift by 1 unit down

Amanda [17]

Answer:

x > 3

Step-by-step explanation:

The inequality to solve is:

5 - 4x < - 7

We will solve this using same method as solving an equation. We will take numbers to one side and variables to another and multiply and divide accordingly.

So,

5-4x

That means "x is greater than 3", so we can write:

x > 3
