Answer:

x= 1/2

and y=3

Step-by-step explanation:

Let's solve your system by substitution.

y=10x−2;2x+y=4

Step: Solvey=10x−2for y:

y=10x−2

Step: Substitute10x−2foryin2x+y=4:

2x+y=4

2x+10x−2=4

12x−2=4(Simplify both sides of the equation)

12x−2+2=4+2(Add 2 to both sides)

12x=6

12x

(Divide both sides by 12)

Step: Substitute

forxiny=10x−2:

y=10x−2

y=10(

)−2

y=3(Simplify both sides of the equation)

Answer:

x= 1 /2

and y

Your friend calculates the distance between points Q(1,5) and R(3,8), as shown below. What is his error?

borishaifa [10]

The distance between two points is the number of units between them.

The distance between Q and R is 3.61 units

It is impossible to determine your friend's error, because the steps are not given in the question. So, I will calculate the distance between Q and R, instead.

The distance (d) between two points is:

$d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}$

So, the distance QR is:

$QR = \sqrt{(1 - 3)^2 + (5 - 8)^2}$

$QR = \sqrt{(- 2)^2 + (- 3)^2}$

Evaluate exponents

$QR = \sqrt{4 +9}$

$QR = \sqrt{13}$

Take square root of 13

$QR = 3.61$

Hence, the distance between Q and R is 3.61 units

Answer:

$\boxed{\bold{57 \ Ft.}}$

Step-by-step explanation:

Assignment: Find area of rectangle without triangle

Area of whole rectangle including triangle: 66 Feet

(6 * 11 = 66)

Area of Triangle: $\bold{\frac{1}{2}Base \ \cdot \ Height }$

Height: 3

Base: 6 (Solved by using this: (11 - 2 + 3))

Half of base: 3

3 * 3 = 9

66 - 9 = 57

A sports team is building a new stadium on a rectangular lot of land. The lot measures 8x by 12x and the field will be 3x by 6x.

ddd [48]

All area : 8x*12x=96x^2
Area for field : 3x*6x=18x^2
Area of land wich will be left for the bleachers,restrooms,and other parts of the stadium: 96x^2-18x^2=78x^2
So the answer is A.78x^2
