Answer: B. (6,4)

Find x for the 2nd equation

3x + 6y = 42

3x = 42-6y

x= (42-6y) / 3

Place the value of x in the first equation and find for y then.

4x - 3y= 12

4{(42-6y)/3} - 3y = 12

So the answer for y is 4

Now, you know the value of y is 4.

4x - 3*4 = 12

4x - 12 = 12

x= 12+12 /4

x= 6

So x is 6 and y is 4. So the answer is B.

Korolek [52]

Answer:

Tenley has to deposited any amount from $50 and above.

Step-by-step explanation:

From the above question, we can deduce that if your bank balance is below 0, = - , you would be charged $30

Hence,

First she has to pay the bank charges of $30, and to prevent the outstanding charge of $19.95 for generating about charge she has to deposit any amount above $19.95

The amount she has to deposit is

$30 + (x > $19.95)

Assuming x is $20 and above

= $30 + $20 = $50

Hence, Tenley has to deposited any amount from $50 and above.

Write an equation of the line with the given information. m. 4. A(-1.-5)
11Alexandr11 [23.1K]

Answer:

An equation of the line with the given information with

m = 4 and point A(-1, -5) is:

  • y=4x-1

Step-by-step explanation:

As the equation of a line in point-slope form is given by:

y-y_1=m\left(y-x_1\right)

where m is the slope.

Given:

  • the slope m = 4
  • the point A(-1, -5)

Substituting the values in the equation of a line in point-slope form

y-y_1=m\left(x-x_1\right)

y\:-\:\left(-5\right)\:=\:4\:\left(x\:-\:\left(-1\right)\right)

y+5=4\left(x+1\right)

subtract 5 from both the sides

y+5-5=4\left(x+1\right)-5

y=4x-1

Therefore, an equation of the line with the given information

with m = 4 and point A(-1, -5) is:

  • y=4x-1

blondinia [14]

Answer:

Step-by-step explanation:

If you are solving for the equation 2x + 19 = 0, the steps are as follows.

2x+19=0

2x = - 19 (Move the 19 over to the other side)

x = - 9 1/2 (divide both sides by 2 to get x by itself.)
