A plumber charges $70 per hour plus $40 dollars for the call. What does he charge for 4 hours of work
Varvara68 [4.7K]
First, let's create an equation for this problem. 
($70 × 4) + $40

Now, all you would have to do is solve it using the order of operation (PEMDAS).
($70 × 4) + $40 = $280 + $40
$280 + $40 = $320

The plumber charged $320. 

I hope this helps!

G(0)=-6/7 into a order pair
Juliette [100K]

Answer:

(0, -6/7)

Step-by-step explanation:

You want an ordered pair equivalent to G(0)=-6/7.  Here "y" = -6/7 and "x" = 0.  The desired ordered pair is thus (0, -6/7):  the x-coordinate comes first and the y-coordinate second.

James determined that these two expressions were equivalent expressions using the values of x = 4 and X= 6. Which
yarga [219]

Answer:

When x = 2, both expressions have a value of 18

The expressions have equivalent values for any value of x.

The expressions have equivalent values if x = 8.​

Step-by-step explanation:

7x+4            3x+5+4x-1

Let x=2

7*2 +4 = 18

3*2+5+4*2-1 = 6+5+8-1=18

When x = 2, both expressions have a value of 18

The expressions are only equivalent for x = 4 and x = 6.

False, they are both equal when x=2

Try x=1

7+4 =11    3+5+4-1 = 11

They are equal with an odd value

When x = 0, the first expression has a value of 4 and the second expression has a value of 5.

4   5-1 =4   false

The expressions are only equivalent when evaluated with even values.  false

The expressions should have been evaluated with one odd value and one even value.  my best guess is false, if it is true for 2 values it is true for all values

The expressions have equivalent values if x = 8.​  true

7*8 +4 = 60    3(8)+5 +4(8) -1 =60

The expressions have equivalent values for any value of x.

7x+4     3x+4x +5-1  = 7x+4

They are always equal
