-3a + 4 = -14
What the answer to this

Answers

Answer 1

Answer:

-6

Step-by-step explanation:

-3a + 4 = -14

-3a = -14 - 4

-3a = -18

a = -18 / 3

a = -6

Answer 2

Answer:

a = 6

Step-by-step explanation:

Step 1: Subtract 4 from both sides.

-3a + 4 - 4 = -14 - 4

+4 and -4 cancel out.

Step 2: Subtract 4 from -14 to get -18.

-3a = -18

Step 3: Divide both sides by -3.

a = -18/-3

Step 4: Divide -18 by -3 to get 6.

a = 6

Let's check our work by substituting a for 6.

-3(6) + 4 = -14

Multiply -3 by 6 to get -18.

-18 + 4 = -14

Add -18 and 4 to get -14.

-14 = -14

This is true, so a = 6.

(504-300+800) x 100 / 3?

Answers

Answer:

  [1]    x - 6y = 3

  [2]    x + 2y = 5

Graphic Representation of the Equations :

   -6y + x = 3        2y + x = 5  

Solve by Substitution :

// Solve equation [2] for the variable  x

 [2]    x = -2y + 5

// Plug this in for variable  x  in equation [1]

  [1]    (-2y+5) - 6y = 3

  [1]     - 8y = -2

// Solve equation [1] for the variable  y

  [1]    8y = 2

  [1]    y = 1/4

// By now we know this much :

   x = -2y+5

   y = 1/4

// Use the y  value to solve for  x

   x = -2(1/4)+5 = 9/2

Solution :

{x,y} = {9/2,1/4}

Find the equation for the circle with center (3,−5) and diameter of length 8.

Answers

Answer:

(x-3)² + (y+5)² = 16

Step-by-step explanation:

Radius will be half of diameter means that radius = r = 8/2 = 4.

With Center (h,k) the equation of circle is

(x-h)² + (y-k)² = r²

so by putting values answer will be

(x-3)² + (y+5)² = 4²

(x-3)² + (y+5)² = 16

10. One number is twenty more than eight times another number. The sum of the
numbers is eleven. Find the two numbers.

Answers

Answer:

the two numbers are 12 and -1.

Step-by-step explanation:

Let the large number be represented by x and the smaller number by y.

So that;

x = 8y + 20 .................. 1

x + y = 11 ................... 2

From equation 2,

x = 11 - y .......... 3

Substitute equation 3 into equation 1 to have,

11 - y = 8y + 20

11 - 20 = 8y + y

-9 = 9y

divide through by 9 to have,

y = -1

Substitute the value of y in equation 3,

x = 11 - (-1)

  = 11 + 1

  = 12

x = 12

x = 12, y = -1

The two numbers are 12 and -1.

Part B 1/2-5/8-7/9=7/9-5/8-1/2

Answers

Answer:

False

Step-by-step explanation:

1/2 - 5/8 - 7/9 = 7/9 - 5/8 - 1/2

Add 5/8 to both sides.

1/2 - 7/9 = 7/9 - 1/2

Factor -1 out of the right side.

1/2 - 7/9 = -1(-7/9 + 1/2)

1/2 - 7/9 = -1(1/2 - 7/9)

1/2 - 7/9 and 7/9 - 1/2 are opposites. Opposites are not equal unless they are both zero.

Wyatt is saving up to buy a new bicycle. He already has $60 and can save an
additional $6 per week using money from his after school job. How much total money
would Wyatt have after 6 weeks of saving? Also, write an expression that represents
the amount of money Wyatt would have saved in w weeks.

Answers

Answer:

Expression: 6w+$60 Money: $99

Step-by-step explanation:

So, let's find the ammount for 6 weeks

We know he can make $6 per week, so we ned to multiply 6*$6 to get your answer

So, 6 ( weeks ) * 6 ( dollars) = $36 for 6 weeks

Then, we ned to add the $60 he already has saved up, so $60+$39=$99

For the equation, We know that we need to multioply the number of weeks by 6, as shown by how we solved the last problem

So, 6*w=6w

Then we need to add $60

So, we get 6w+$60 for the expression
