Solve for A<br> 3(4A + 4) = 3A + 8A + 1 + 8
kvasek [131]

Answer:

a=−3

Step-by-step explanation:

Let's solve your equation step-by-step.

3(4a+4)=3a+8a+1+8

Step 1: Simplify both sides of the equation.

3(4a+4)=3a+8a+1+8

(3)(4a)+(3)(4)=3a+8a+1+8(Distribute)

12a+12=3a+8a+1+8

12a+12=(3a+8a)+(1+8)(Combine Like Terms)

12a+12=11a+9

12a+12=11a+9

Step 2: Subtract 11a from both sides.

12a+12−11a=11a+9−11a

a+12=9

Step 3: Subtract 12 from both sides.

a+12−12=9−12

a=−3

Answer:

a=−3

How many solutions will each system of linear equations have? Match the systems with the correct number of
JulsSmile [24]

Answer:

Step-by-step explanation:

Given that,

y = x + 6 equation 1

3x - 3y = -18.  Equation 2

Substitute equation 1 into equation 2

3x-3(x+6) = -18

3x - 3x - 18 = -18

-18 = -18

Therefore, it has no solution. Check attachment for echelon matrix solution

B. y = -2x + 5 equation 1

2x + y = -7.  Equation 2

Substitute equation 1 into 2

2x -2x + 5 = -7

5 = -7

Since the equation is not balance, then, it has infinite numbers of solution.

C. y = -4x + 11.  Equation 1

6x + y = 11.   Equation 2

Substitute equation 1 into 2

6x - 4x + 11 = 11

2x = 11 - 11

2x = 0

x = 0

Also, y = -4x + 11

y = 0 + 11 = 11

Then, this has a unique solution I.e. one solution.

Write the equation of the line that passes. Throught the point (-2,1)and (0,8)put your aswer in fully reduce point slope form un
Soloha48 [4]

Answer:

Step-by-step explanation:

first, we need to find the slope

slope = (y2 - y1) / (x2 - x1)

(-2,1)...x1 = -2 and y1 = 1

(0,8)...x2 = 0 and y2 = 8

now sub

slope = (8 - 1) / (0- (-2) = 7/(0 + 2) = 7/2

point slope form : y - y1 = m(x - x1)

using point (-2,1)....x1 = -2 and y1 = 1

slope(m) = 7/2

now sub

y - 1 = 7/2(x - (-2) =

y - 1 = 7/2(x + 2) <==== here is one answer

y - y1 = m(x - x1)

using point (0,8)...x1 = 0 and y1 = 8

slope(m) = 7/2

now sub

y - 8 = 7/2(x - 0) <===== another possible answer

What is the value of x in the equation 2/3(1/2x+12)=1/2(1/3x+14)-3?
Jlenok [28]

Answer:

  a.  -24

Step-by-step explanation:

Multiply by 6 ...

  2/3(1/2x+12)=1/2(1/3x+14)-3

  4(1/2x +12) = 3(1/3x +14) -18  . . . . . . multiply by 6

  2x +48 = x +42 -18 . . . . . . . . . . . . . .eliminate parentheses

  x = 24 -48 = -24 . . . . . . . . . . . . . . . . simplify and subtract (x+48)
