Answer:

3) Midpoint is (-4,0.5)

Option A is correct.

4) Midpoint is (2.5,0)

Option B is correct.

5) The factors are (x+4)(x-7)

Option C is correct.

6) The factors are (x+4)(x+2)

Option A is correct.

Step-by-step explanation:

Question 3

Find midpoint of the following:

(2,-7), (-10,8)

The formula used to find midpoint is: $Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} )$

We have $x_1=2, y_1=-7, x_2=-10,y_2=8$

Putting values and finding midpoint

$Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} )\\Midpoint=(\frac{2-10}{2},\frac{-7+8}{2} )\\Midpoint=(\frac{-8}{2},\frac{1}{2} )\\Midpoint=(-4,0.5 )$

So, Midpoint is (-4,0.5)

Option A is correct.

Question 4

Find midpoint of the following:

(2,-10), (3,10)

The formula used to find midpoint is: $Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} )$

We have $x_1=2, y_1=-10, x_2=3,y_2=10$

Putting values and finding midpoint

$Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} )\\Midpoint=(\frac{2+3}{2},\frac{-10+10}{2} )\\Midpoint=(\frac{5}{2},\frac{0}{2} )\\Midpoint=(2.5,0 )$

So, Midpoint is (2.5,0)

Option B is correct.

Question 5

Factor each completely

$x^2-3x-28$

We will break the middle term and find factors

$x^2-3x-28\\=x^2-7x+4x-28\\Taking\:common\\=x(x-7)+4(x-7)\\=(x+4)(x-7)$

So, the factors are (x+4)(x-7)

Option C is correct.

Question 6

Factor each completely

$x^2+6x+8$

We will break the middle term and find factors

$x^2+6x+8\\=x^2+4x+2x+8\\=x(x+4)+2(x+4)\\=(x+4)(x+2)$

So, the factors are (x+4)(x+2)

Option A is correct.

B. if the two surge protectors are arranged in parallel, what is the probability that a voltage surge will not damage the tele

Free_Kalibri [48]

<span>Let's first set the two surge protectors as p and q. In order to solve this question we would also need another variable: the probability x of working correctly when a voltage surge occurs. So, the probability that the voltage surge will not damage the TV is: 1 - 0.06^2 divide by x^2.</span>

What’s the answer to this equation : HELP ASAP

RSB [31]

2/3 x - 1/5 x = x - 1

Change the fractions to have the same denominators:

10/15 x - 3/15 x = 15/15 x - 1

Simplify the left side of the equation:

7/15 x = 15/15x - 1

Get everything to the right side of the equation:

0 = 8/15 x - 1

Move the (1) to the left side:

1 = 8/15x

Multiply 15 to both sides:

15 = 8x

Divide both sides by 8

15/8 = x

Answer is x=8/15

Answer:

10 miles in 50 minutes

Step-by-step explanation:

1. Divide 20 into 4 to see the unit rate of 1 mile.

2. If you continue on from 20 to 50 you will notice it will be 10 miles.

You welcome.
