I need help solving this problem. ​

Replace y = -4x into y = 3x + 28

-4x = 3x + 28

Minus both side by 3x

-7x = 28

x = -4

Recheck : - 4 x (-4) = 3 x (-4) + 28
16 = -12 +28 = 16 (t)

Answer:

(- 4, 16 )

Step-by-step explanation:

y = 3x + 28 → (1)

y = - 4x → (2)

substitute y = 3x + 28 into (2)

3x + 28 = - 4x ( add 4x to both sides )

7x + 28 = 0 ( subtract 28 from both sides )

7x = - 28 ( divide both sides by 7 )

x = - 4

substitute x = - 4 into (2)

y = - 4(- 4) = 16

solution is (- 4, 16 )

Answer:

X+m=y

M=1/1

You add 3, then 4, 5, 6

your slope (m) will be 1/1=1

1+3=4

2+4=6

3+5=8

4+6=10

5+7=12    

Hope this helps! Brainliest is appreciated :)

Answer:

127.3 feet.

Step-by-step explanation:

The line from first base to third base is the hypotenuse of a right triangle, with the right angle at home base.

Since this is a right triangle, we will use the Pythagorean Theorem to find the hypotenuse.

So, let a = one side and let b = the other side of the right triangle. And, let c = the hypotenuse.

The Pythagorean Theorem is:

c^2 = a^2 + b^2.

So, c= sqrt(a^2 + b^2)

And we have: c= sqrt(90^2 + 90^2)

= sqrt(8100 + 8100) = sqrt(16,200)

= 127.3 ft.

Conclusion: The distance from first base to third base is 127.3 ft, (approximately).

Answer:

0.2 km per minute

Step-by-step explanation:

if he left for home when he was 4 miles from home, at 11:40, and got home 20 minutes later then his rate of speed is 20 minutes to go 4 miles (20/4), which if you divide both numerator and denominator by 20 you get 1 minutes for 0.2 km

Answer:

Answer: The larvae of a silk moth secrete the silk thread which is used to make clothes. Honey bees produce and store honey which is nutritious food. Silkworm is a creamy white colored insect which is about 2-3 cm long and shining in nature.

Bee larvae have been shown to be an excellent food source for rearing insects

Silk worm larvae is used in extracting silk and thus help in making clothes.

Bee larvae is used in pest control.

The silkworms feed solely on large amounts of leaves from the mulberry tree for around 30-40 days

The majority of honey bee larvae eat honey, but larvae that are chosen to become future queens will be fed with royal jelly.

Answer:

1/4

unsimplified = 2/8

Step-by-step explanation:

2/8 is your answer because

you can see here that there are 8 bars that are being covered by his total sales. That means that 8 is the denominator, then, the money is going 2 more bars than 225 dollars. So if we see, then we can find out that the sales are going up till 275, and the difference of 275 and 225 is 50. And each bar over here represents a difference of 25. That means that 2/8 (1/4) of the sales are more than $225.

So hence, your answer is 1/4

Answer:

1/4

Step-by-step explanation:

From inspection of the box plot:

The left whisker (min value) to Q1 represents the bottom 25% of the data

Q1 to Q2 represents the second 25% of the data

Q2 to Q3 represents the third 25% of the data

Q3 to the right whisker (max value) represents the top 25%

Therefore, the sales of over $225 represent the top 25% of the data.  

25% represented as a fraction is 25/100 = 1/4

Answer: A :)

Step-by-step explanation:

Here's how to solve your equation step by step:

−21−9k=−8(6k+3)

Step 1: Simplify both sides of the equation.

−21−9k=−8(6k+3)

−21+−9k=(−8)(6k)+(−8)(3) (Distribute)

−21+−9k=−48k+−24

−9k−21=−48k−24

Step 2: Add 48k to both sides.

−9k−21+48k=−48k−24+48k

39k−21=−24

Step 3: Add 21 to both sides.

39k−21+21=−24+21

39k=−3

Step 4: Divide both sides by 39.

39k/39 = -3/39

Here's the answer: -1/13 or -0.08.

Answer: The calculation is correct.

Step-by-step explanation:

If Hernando ate 2/8 of a pizza for a dinner, the remaining pizza will be:

= 1 - 2/8

= 6/8

If he gave his 6 friends the rest of the pizza and told them to share it equally, each person will get:

= 6/8 ÷ 6

= 6/8 × 1/6

= 1/8

Each person will get 1/8 each

Since he also concluded that each person received 1/8 of the whole pizza, Hernandos calculations are correct

Hey there!

First, let's solve this maths problem:

7a-(3+8a)

Here we should use the Distributive Property and distribute -

Wait, what? Distribute a minus? Yeah! The minus sign (in this case) is the same as -1:

7a-3-8a

Now, why did the plus sign change to the minus sign?

Because a negative times a positive is a negative.
