Parallel lines share the same slope. y=3x+7 has a slope of 3, so that is the slope of the parallel line. Then use y=mx+b an plug in (2,4).
y=3x+b
4=3(2)+b
4=6+b
b=-2

So the equation is y=3x-2

The area of a square is 49 cm^2. What is the perimeter, in cm, of the square?
rewona [7]

Answer:

P = 28 cm

Step-by-step explanation:

The area of a square is

A = s^2 where s is the side length

49 = s^2

Taking the square root of each side

sqrt(49) = sqrt(s^2)

7 =s

Now find the perimeter of the square

P = 4s

P = 4(7)

P = 28 cm

The sum of two numbers is 27 and their product is 50. Find the numbers.?<br><br>​
san4es73 [151]

Answer:

a + b = 27

=> a = 27 - b

ab = 50

So, (27 - b) x b = 50

27b - b^2 = 50

b^2 - 27b + 50 = 0

Solving, b = 25, 2

Hence,

Case 1: b = 25, a = 2

Case 2, b = 2, a = 25

If 2 - 4(y + 1) = 2y + 16, what is the value of y?<br> Show all work, please.
VladimirAG [237]

Answer:

y = -3

Step-by-step explanation:

2 - 4(y + 1) = 2y + 16

2 - 4y - 4 = 2y + 16

2 - 4 = 6y + 16

- 2 = 6y + 16

- 18 = 6y

-3 = y

"The sum of 4 and a number, divided by 2 is less than -6."​
Ksenya-84 [330]

Answer:

\frac{4+n}{2} < -6, n < -16

Step-by-step explanation:

To write this into an inequality you need to recognize keywords. The first keyword is "sum" this means the two numbers must be added; so the first part of the inequality is 4+n. Then, it says the sum is "divided by" 2; this means both numbers must be put over two like \frac{4+n}{2}. Finally, this is "less than" negative. Therefore, this must be an inequality with a sign opening towards -6. So the final answer is \frac{4+n}{2} < -6.

To solve the inequality isolate the variable. Multiply both sides by 2, so the new inequality is 4+n. Next, subtract 4 from both sides. The answer is n < -16.
