The correct answer is A) a translation 2 units right and 4 units down.

Both of the reflections listed would keep the digits but change their signs and/or placement.
A translation 2 units right subtracts 2 from the x-coordinate. A translation 4 units down subtracts 4 from the y-coordinate. Comparing each pre-image point to its image, we can see that is what happened.

Answer:

Part a) $22.95+0.43x \leq 25$

Part b) The maximum number of candy bars that you can purchase is 4

Part c) The change would be $\$0.33$

Step-by-step explanation:

Part a) Write an equation representing your shopping experience and use x for the number of candy bars

Let

x -----> the number of candy bars

we know that

The inequality that represent this problem is equal to

$2(3.50)+2(2.75)+10.45+0.43x \leq 25$

$22.95+0.43x \leq 25$

Part b) Solve the equation to determine how many candy bars can you purchase?

$22.95+0.43x \leq 25$

Solve for x

Subtract 22.95 both sides

$0.43x \leq 25-22.95$

$0.43x \leq 2.05$

Divide by 0.43 both sides

$x \leq 2.05/0.43$

$x \leq 4.8$

The maximum number of candy bars that you can purchase is 4

Part c) How much change would you have left?

If you purchase 4 candy bars

then

$22.95+0.43(4)=\$24.67$

therefore

$\$25-\$24.67=\$0.33$

How to find where the equations meet.

zzz [600]

The first sentence → x - 2y = -1
the second one → 3x - 2y = -3

multiply the first one by -1
you can get → -x + 2y = 1

plus two sentences together
you can get → 2x = -2

so you are able to know that x = -1
and y = 0

If 3t − 7 = 5t , then 6t = how do you solve this

Alik [6]

$3t-7=5t \ \ \ |\hbox{subtract 3t} \\ -7=5t-3t \\ -7=2t \ \ \ |\hbox{multiply by 3} \\ \boxed{6t=-21}}$
