Answer:

x = 4

Step-by-step explanation:

3x+2−x+2=x+8  

Add the numbers

3 + 2 − + 2 = + 8 3 + 4 − = + 8 2

Combine like terms

3 + 4 − = + 8 2 + 4 = + 8 3

Subtract   4  from both sides of the equation  

Simplify

Subtract the numbers  

2x+4−4=x+8−4

2 = + 8 − 4  

Subtract the numbers

2 = + 4 5

Subtract  x from both sides of the equation

2 = + 4 2 − = + 4 − 6

Simplify

Combine like terms

Multiply by 1

Combine like terms

= 4

Solution

= 4

Answer:

y = 3x - 5  

Step-by-step explanation:

1) First, place the given equation in slope-intercept form, represented by the formula [tex]y = mx +b[/tex], to find the slope. Whatever [tex]m[/tex] or the coefficient of x-term is will be the slope. Isolate y in the equation:

[tex]x + 3y = -6\\3y = -x -6\\y = -\frac{1}{3}x-2[/tex]

So, the slope of that line is [tex]-\frac{1}{3}[/tex]. Lines that are perpendicular have slopes that are opposite reciprocals, thus the slope of the new line will be 3.

2) Now, use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] to find the equation of the new line. Substitute real values for the [tex]m[/tex], [tex]x_1[/tex] and [tex]y_1[/tex] in the equation.

Since [tex]m[/tex] represents the slope, substitute [tex]-\frac{1}{3}[/tex] in its place. Since [tex]x_1[/tex] and [tex]y_1[/tex] represents the x and y values of one point the line passes through, substitute the x and y values of (-1,-8) into the formula as well. Then, isolate the y in the resulting equation to put the equation in slope-intercept form and find an answer:

[tex]y-(-8) = 3 (x-(-1))\\y + 8 = 3(x+1)\\y + 8=3x + 3\\y = 3x -5[/tex]

Answer:

Scalene triangle

Step-by-step explanation:

Answer:

Step-by-step explanation:

I can only tell you that 4x-y=6 is parallel to y=4x-6. Do u mind sort out the rest of the variables and the numbers on your own?

The lines parallel to given line are y + 1 = 4(x - 2) and y = 4x + 11. Therefore, option C and D are the correct answers.

The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.

Given that, the equation of a line is 4x-y=6.

Now, y=4x-6

Here, the slope of the equation is 4.

The slope of a line parallel to given line is m1=m2

So, here the slope of a parallel line is 4.

y + 1 = 4(x - 2) and y = 4x + 11 have same slope, then they are parallel to given line.

Therefore, option C and D are the correct answers.

Answer:

∠AOB = 112°

Step-by-step explanation:

mentally draw line segment OC

that line bisects 124° so ∠OCB = 1/2(124°) = 62°

ΔOCB is isosceles because OB = OC

∠OBC = 62° because it is equal to ∠OCB

all triangle interior angles add up to 180°

∠BOC = 180° - 62° - 62° = 56°

∠AOC = 56° because OC was a bisector of ∠AOB

∠AOB = 56° + 56° = 112°

Complete question :

Imagine you are starting an office supply business. Your overall costs for supplies are $100. You plan on selling binders for $4 each and pencils for $2 each. Let x represent the number of binders sold and y represent the number of pencils sold. Give an expression for the profit made.

Answer:

(2y + 4x) - $100

Step-by-step explanation:

Given that:

Cost of supply = $100

Supplies :

binders, sales price = $4

Pencils, sales price = $2

Number of binders sold = x

Number of pencils sold = y

The revenue from sale :

(Cost of pencils * number of pencils) + (cost of binders * number of binders)

Revenue = 2y + 4x

Profit, p = Revenue - Cost of supply

p = (2y + 4x) - $100

Answer:9.7

Step-by-step explanation:

Answer:

A) s=32t

B) 224 ft/s

Step-by-step explanation:

A)

In the form (time, speed), the question gives us the following data: (1,32) and (5,160). Since we are told that the relationship between​ time, t, and​ speed, s, is linear, we know the equation will fit the formula y=mx+c, where m is slope c is the y-intercept and y and x are the co-ordinate values. Plug in (1,32) and (5,160) to find the formula:

y=mx+c

s=mt+c

32=1m+c

c=32-m

160=5m+C

160=5m+32-m

128=4m

m=32

c=32-m

=32-32=0

So our equation is s=32t

B)

s=32t

s=32(7)=224 ft/s

Answer:

w = 32

Step-by-step explanation:

Remark

The value of the exterior angle (marked w + 33) = the sum of the two angles not connected to it. w and w + 1

Equation

w + w + 1 = w + 33

Solution

2w + 1 = w + 33      Subtract w from both sides.

2w - w + 1 = 33       Combine

w + 1 = 33               Subtract 1 from both sides.

w = 33 - 1

w= 32

Step-by-step explanation:

bl  is blue eyes     h = hazel eyes      br = brown eyes

eq 1)    bl + h + br  = 34                sum of all the students

eq 2)   bl +  2  =  h                       blue eyes plus 2 equal hazel eyes

eq 3)   br  =  2( bl + h )                 there are twice as many brown eyed student

                                                    as blue eyed and hazel eyed students

eq 1)    bl + h + br  = 34                  substitute for h in    eq 2)  bl + 2  =  h      

           bl + (bl + 2) + br  = 34

eq 4)    2bl + 2 + br  = 34            a new equation is created without h

eq 3)     br = 2(bl + h)                     substitute in  for h into eq 3) using eq 2)

             br  = 2bl + 2h                  remember eq 2 was  be + 2  =  h

             br  = 2bl + 2(bl + 2)

eq 5)      br  = 4bl + 4                    another eq WITHOUT h

now solve eq 4) and eq 5)        by subsitition  

eq 5)      br  = 4bl + 4                 sub bl into eq 4)

eq 4)     2bl + 2 + br  = 34  

            2bl + 2 + (4bl + 4)  = 34           ONE equation with ONE unknown

                                                                solve for bl

            2bl + 4bl  + 2  +  4    = 34

                  6bl + 6   =  34

                  6bl + 6 - 6   =  34  -  6

                  6bl    =  28

                  3bl     =  14

                   bl    = 14/3  =   4 2/3         so who has the 2/3 eye???

     none of these numbers match the solution options

need to check my answer for sure my math was correct                    

  bl + h + br  = 34        bl = 14/3      

                                    eq 2)   bl +  2  =  h       14/3 + 6/3  =  h      h  = 20/3

                                    eq 3)   br  =  2( bl + h )

                                               br = 2(14/3 + 20/3)

                                               br = 2(34/3)

                                               br = 68/3    

     bl    +     h    +     br       =       34

   14/3  +  20/3  +   68/3  =    102/3         102/3  = 34        the numbers check

************   i suspect the equation was typed incorrectly    ****************

if the total number of students were 36

               blue eyes   =   5

               hazel eyes  =   7

               brown eyes   =  2 times (5 +7)   =  24

          5 + 7 + 24 = 36

     again none of these numbers match option

if the total number of students were 24

               blue eyes   =   3

               hazel eyes  =   5

               brown eyes   =  2 times (5 +7)   =  16                    D = 16

          3 + 5 + 16 = 24
