i believe the correct answer would be the first box, and the very last box.
explanation: comparing between sides AB and sides DE you can see that side AB is 3 long and side DE is 4 long. also comparing sides DF and AC, you can see that side DF is 4 long and side AC is 3 long. this shows that those two sides proportions are not similar. i hope this helps!

x = 0 is a vertical line.

If a point is reflected across a vertical line, x-value becomes the distance from the reflection line and the sign changes most likely.

Thus if (-4,3) is reflected across a vertical line, its sign change and it becomes (4,3)

The answer is (-3,4) because mirrored give you -3 and then mirror the -4 and you get just 4

Deon's chocolate bar is 72% cocoa. If the weight of the chocolate bar is 73 grams, how many grams of cocoa does it contain? Round your answer to the nearest tenth.

Answers

Answer: 52.6 grams of cocoa

Step-by-step explanation:

Facts:

the chocolate bar is 72% cocoa

it weighs 73 grams (g)

Cocoa (in grams)= ?

Step 1: Find 72% of 73

72% of 73= 52.56

52.56

56-> 60

52.6

72% of 73 grams is 52.56
Meaning we have 52.56 grams of cocoa
If we round to the nearest 10th it’s 50 grams of coca

This table of values represents a linear function. Enter an equation in the form y=mx+b that represents the function defined by this table of values

Answers

Answer:

y=-2x+3

Step-by-step explanation:

m = slope = y/x = -4/2 = -2

b = y intercept = 3

Answer:

f(x)=-2x-4

Step-by-step explanation:

First of all, I want to say that I'm a 5th grade kid, and I'm studying linear functions in eight grade. The equation is f(x) = mx + b. The b is y intercept. Since the y is -1, we know that f(x)=mx+-1, or f(x)=mx-1. Then, we look that the x. It's 2. Then, substitute 2 for m. F(x) = 2x-1. I'm gonna do the other ones. f(x)=4x-5, f(x) = 6x-9.  We know that the x is substracting 2. The y is subtracting 4. So the rule is f(x) = -2x-4

I’m needing help figuring this out. thank you if you can help me with this.

A swimming pool holds 250,000 gallons of water and is being drained at 200 gallons per minute. How many gallons remain in the pool after 5 minutes than after 20 minutes?

Answers

Answer:

After 5 minutes, the pool will hold 249,00 gallons of water.

After 20 minutes, the pool will hold 246,000 gallons of water.

After 5 minutes the pool will have 249,000 gallons since 5x200=1000 and 250,000-1000=249,000.
After 20 minutes it will be at 246,000 gallons since 20x200=4000 and 250,000-4000= 246,000.
