Step-by-step explanation:

2: Distributive property (the -2/3 was distributed to (x+12) )

3:combine like terms (the -2/3x was combined with +1/3x)

4:addition property of equality (the -8 was added to both sides of the equation)

5:transitive property (divided both sides by -1/3 to get x alone)

6:symmetric property (rewrote the answer)

y=12x+11 If x=−1, then y= ?
(write your answer as a decimal, please)

Answers

y = -1
the expression is already in decimal form
Answer:
y = -1

Process:
y = 12x + 11
y = {12*(-1)} + 11
y = -12 + 11
y = -1

solve the equation -2y + 6 =-12

Answers

Answer:

[tex] - 2y + 6 = - 12 \\ - 2y = - 12 - 6 \\ - 2y = - 18 \\ y = \frac{ - 18}{ - 2} \\ y = 9[/tex]

Answer:

-2y + 6 = -12 (subtract 6 from both sides to get the y-term alone)

-2y = -18 (divide both sides by -2 to get y alone)

y = 9 (this is your answer)

3. slope of CB = rise/run = 5/12      BF = 5    CF = 12

BF ⊥ DF

DB (seg of two farthest points) = √BF²+DF² = √5²+32² = √1049 = 32.4

4. f(x) = 2x² - 5x -3      vertex : A (h,k)  for f(x) = ax² + bx +c

h = - b/2a = - (-5 / 4) = 5/4

f = f(h) = 2*(5/4)² - 5*(5/4) - 3 =25/8 - 25/4 -3 = -49/8

A (5/4 , - 49/8) i.e. (1.25 , - 6.13)

negative root:   2x² - 5x -3 = (2x+1) (x- 3)      x = - 1/2      y = 0

B (- 1/2 , 0)

x coordinate of AB: 1/2 (1.25 + -0.5) = 0.375

A polygon shaped like an arrow is shown. The total height of the arrow head and the arrow tail is 7 inches. The base of the arrow tail is 4 inches. The width of the arrow is 6 inches, and the height of the tail of the arrow is 5 inches.

Each arrow is to be painted red. How much area needs to be painted for 1 arrow?

To make it easier heres the picture!:

Answers

Answer:

32 Inches

Step-by-step explanation:

First, split arrow into triangle and rectangle

----------------------------------------------------------------

Rectangle:

Area=5x4

       =20

--------------------------------------------------------------

Triangle:

Area=6x2

       =12

-----------------------------------------------------------------

Add both shapes areas together

to find total

------------------------------------------------------------------

Total=32 Inches

The solution is : 26 sq.Inches area needs to be painted for 1 arrow.

What is area ?

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

First, split arrow into triangle and rectangle

Rectangle:

Area=5x4

      =20

Triangle:

Area=6x2/2

      =6

Add both shapes areas together

to find total

Total=20 + 6 sq.Inches

       = 26 sq.in.

Hence, The solution is : 26 sq.Inches area needs to be painted for 1 arrow.
