Answer:
-2/3.
Step-by-step explanation:
To find the slope of a line given two points, you should use the formula, Slope=y2-y1/x2-x1.In this exercise is given the coordinates of two points and it is asked to find the slope of the line which intercepts both points, which are (1,7) and (10,1). To find the slope, you should substitute the given coordinates into the previous mention formula. Slope=y2-y1/x2-x1Slope=(7-1)/(1-10)Slope=-6/9Slope=-2/3The slope of the line that passes through the points.
Answer:
sin A = 
Step-by-step explanation:
sin A = opposite side/hypotenuse
sin A = 
/ 12 = 
We are given some statements, we need to find which of the given statements is an advantage to using equations.
<h3><em>The correct option is </em></h3><h3><em>(A). When given two names for the same quantity, you can use algebra to solve the equations.</em></h3>
Incorrect options are :
(B). You can forget what an equation represents when it is used by itself.
(C). every problem needs an equations if you want to solve it.
%=percent
percent means parts out of 100
20%=20/100
'of' means multiply
20% of 100 units means
20/100 times 100 units=2000/100 units=20 units
