Simplify each of the following expressions: 3(x + 2) + 4(x − 2) 2(x + y) − 3(x + y) −(y + 8) + 4(6 − y) 2(4x + 3) − 3(x + 1)

Marrrta [24]

Answer:

7x-2, -x-6y+16, 5x-3

Step-by-step explanation:

I'm guessing the three expressions are:

1. 3(x+2) + 4(x-2)

2. 2(x+y) - 3(x+y) - (y+8) + 4(6-y)

3. 2(4x+3) - 3(x+1)

... 1. 3(x+2) + 4(x-2)

= 3x + 6 + 4x - 8

= 7x - 2

... 2. 2(x+y) - 3(x+y) - (y+8) + 4(6-y)

= 2x + 2y - 3x - 3y - y - 8 + 24 - 4y

= -x - 6y + 16

... 3. 2(4x+3) - 3(x+1)

= 8x + 6 - 3x - 3

= 5x - 3

Write the word sentence as an inequality. Then solve the inequality. 3/4 is greater than or equal to a number k divided by -8

Novosadov [1.4K]

Answer:

$\frac{3}{4} \geq \frac{k}{-8}$
k ≥ -6

Step-by-step explanation:

Re-arrange: $\frac{3}{4} \geq \frac{k}{-8}$
Multiply each side by -8 to cancel out the -8 under k. It should now look like this: k ≥ -6

I hope this helps!

Segment AB has endpoints A(-1,3) and B(0,7). What is the length of AB?

ololo11 [35]

Answer:

$\sqrt{17}$

Step-by-step explanation:

Calculate the length (d) using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 1, 3) and (x₂, y₂ ) = (0, 7)

d = $\sqrt{(0+1)^2+(7-3)^2}$

= $\sqrt{1^2+4^2}$

= $\sqrt{1+16}$

= $\sqrt{17}$ ≈ 4.1 ( to 1 dec. place )
