Answer:

Step-by-step explanation:

The lady gets paid $8 per hour that the shop is opened, so multiply the pay rate ($8) by the amount of hours the shop is opened
$8 * 8 = $64

Now add the $64 onto the expense of running the shop

$64 + $240 = $304

Now take that amount away from Friday's sales

$530 - $304 = $ 226

Profit($226) = Income($530) - Expenses($304)

$226 = $226

=)

How do you get an equation in slope intercept form through the points (-1,-2) and (1,4)
Sever21 [200]
(4+2)/(1+1)= 6/2= 3 is the slope

y + 2 = 3(x + 1)
y+2=3x+3
y= 3x+1

1 For each line
Elena-2011 [213]

Step-by-step explanation:

I'll do line A for you and you can use the formulas to solve lines B and C yourself, since its good for you to practice doing these questions yourself

a)

The gradient, m, is calculated using m = (y2-y1)/(x2-x1) where x1,x2,y1 and y2 can be any ordered pairs on the line.  I'm going to use (4,0) and (7,3) as the 2 points.

m = (3-0)/(7-4) = 3/3 = 1

b)

The y-intercept is where the line intersects with the x-axis. In this case (0,-4)

c)

The equation of a linear line is y=mx+b (or c depending on which country you are from)

y = 1x-4

y=x-4

Now try the other 2 lines yourself!

Which number line shows all the values of that make the inequality - 3x +1 &lt; 7 true? <br>​
Yakvenalex [24]

Answer:

D

Step-by-step explanation:

First, simplify the equation.

-3x+1<7

-3x<6

x>-2 (the sign flips because you are dividing by negative)

> means x is greater than -2 so the line will go towards the right.

Because the sign is >, the dot is open.
