What is the slope between the points (8, -2) and (-7, 10)
lara [203]
Slope formula:
(y2-y1)/(x2-x1)

Substitute in the points into the slope formula.

Slope= [10-(-2)] / [(-7)-8]
Slope= (10+2) / (-15)
Slope= 12/-15
Slope= -12/15
Simplify (3 goes into each)
Slope= -4/5

Hope this helps!! :)

Emmanuel went to the store and
musickatia [10]

Answer:

$148.50

Step-by-step explanation

I solved this by using fractions.

x/450=33/100 is how I set up the problem. 33/100 represents 33%, while x/450 represents how much the jacket costs now.

I then went across and multiplied x by 100, and 450 by 33, which gave me 100x=14850. After this I divided each side by 100 to get 148.5, being the cost of the jacket.

Coordinate grid with plotted ordered pairs, point A at negative 5, 4 point B at 4, 7 point C at negative 2, 7 point D at negativ
RideAnS [48]

The answer should be answer A. (A,C,D,K)

You can easily figure this out by just looking at the graph.  Just look at all points that are in the blue region(overlapping shaded area) and see all the points inside.

H is not included because it falls on the dotted line.  Any point that falls on a dotted line does not satisfy both inequalities.

If the line were solid however, then the point would satisfy both inequalities.  This is because the line would include the <em>greater than or equal to</em> symbol "≥" which means that the point <em>could</em> equal to 8 or be less than 8.  Since the symbol is not used, it doesn't satisfy both equations.

Define a variable and write an equation to model each situation. Then solve. Show your work. Tickets to the county fair for four
Citrus2011 [14]
If x is the childrens ticket
4(x + 1.5) + 5x = 33.30 \\ 4x + 6 + 5x = 33.3 \\ 9x = 33.3 - 6 \\ 9x = 27.3 \\ x =  \frac{27.3}{6}  \\ x = 4.55
so that means that the adults ticket is
x + 1.50 = 4.55 + 1.50 = 6.05
