Answer:

Distance: 8.5440037453175

Step-by-step explanation:

Distance: 8.5440037453175

Steps:

Distance (d) = √(-7 - -10)2 + (-1 - -9)2

= √(3)2 + (8)2

= √73

= 8.5440037453175

Slope and Angle:

ΔX = -7 – -10 = 3

ΔY = -1 – -9 = 8

Slope (m) =

ΔY

ΔX

= 2.6666666666667

θ =

arctan( ΔY )

ΔX

= 69.443954780417°

Equation of the line:

y = 2.6666666666667x + 17.666666666667

y =

8 x

+ 53

When x=0, y = 17.666666666667

When y=0, x = -6.625

Amir has spent the last three months saving money for a $1,400 computer in his local electronics store. So far he has saved $1,2

Fiesta28 [93]

25% off of $1400 equal: 1400 + .25 = 350, so 1400 - 350 = 1050
So now the computer with 25 % off is $1050.
tax 7%, means 1050 + .07 = $73.50 (sales tax charge)

Total computer with 25% off plus 7% tax equal:

$1050 + 73.50 = $1,123.50

Amir has saved $1200, so he has enough money to purchase the computer.

Answer: $Area=5x^2+10x$

Step-by-step explanation:

The area of a rectangle:

$a=h$ × $w$

$a=5x(x+2)$

$a=5x$ × $x+5x$ × $2$

$a=5x^2+10x$

-Result:

$a=5x^2+10x$

Please help! Greatly appreciated sorry for really bad quality

The first answer.

Point P is at (50,-40) the distance from Q to P is 80 units which you can find by subtracting the x of Q (-30) from the x of P (50).
50-(-30)=80
It then tells you point R is vertically above point Q so you know your x value for R will be the same as Q.
Add your distance from Q to P of 80 units to the y value of Q because you are traveling up.
-40+80=40
R will have a point of (-30,40) and a distance of 80 units
