The points are (-4,2) and (3,-4)
using y2-y1/x2-x1
-4-2/3-2
-6/1
slope (m) is -6
to find b part of equation (y=mx+b) plug in point value for x and y
2=-6(-4)+b (multiply -6 and -4)
2=24+b (subtract 24 over)
b=-22
final equation is y=-6x-22
7 * 0.5 + 3 * 0.8 = 3.5 + 2.4 = 5.9
<span>5.9/10 X 100 = 59%
</span><span>59% concentration of new mixture</span>

Answer:
The actual space shuttle is 66 feet tall
Step-by-step explanation:
scale of 1 inch : 12 feet represent the scale of a space shuttle.
It means it has a representation of 1 inch on paper then actual = 12 feet.
But then if the paper(model) changes to 5.5 inches. The actual representation on land will be
Let me write out the equation
1 inch = 12 feet
5.5 inch =( 5.5 inch *12 feet)/1 inch
5.5 Inch= 5.5 * 12 feet
5.5 inch = 66 feet
