Yes.
473 + 161/4 = 634/4 = 158.5
Answer:
Point slope form : 
Slope intercept form: 
Standard form : 
Step-by-step explanation:
From the given graph it is clear that the line is passing through the points, (-4, 0), (-2, 1), (0, 2), and (2, 3).
If a line passes through two points 
and 
, then the equation of line is
Let as consider any two points of the line: (2, 3) and (0, 2).
The equation of line is
The point slope form of the line is .
Add 3 on both sides.
Therefore the slope intercept form of the line is .
Multiply both sides by 2.
Therefore, the standard form of the line is .
Step-by-step explanation:
Option D is the correct answer because we will cross multiply
4/6 = 9/x
4x = 54
X = 27/2
Answer:
Step-by-step explanation:
(a) You use the fact that the lengths RS and ST total the length RT.
RS +ST = RT
(6y+3) +(3y+5) = 80 . . . . . substitute the given values
9y +8 = 80 . . . . . . . . . . . . .simplify
9y = 72 . . . . . . . . . . . . . . . .subtract 8
72/9 = y = 8 . . . . . . . . . . . .divide by the coefficient of y
___
(b) Now, the value of y can be substituted into the expressions for RS and ST to find their lengths.
RS = 6y +3 = 6·8 +3
RS = 51
ST = 3y +5 = 3·8 +5
ST = 29
___
<em>Check</em>
RS +ST = 51 +29 = 80 = RT . . . . the numbers check OK
