Question 5, x could be either 6 or -1.
Answer: C 3x + 5y = 1
Solution:
Step 1: To find the equation of line first using both the coordinates given on the graph find the slope using the formula below.
The coordinates are ( -3, 2 ) and ( 2, -1)
m = y2-y1/x2-x1
m = -1-2 / 2- (-3)
m = -3 / 5
Step 2: Now to find line of equation of line we need to find the y intercept using the equation:
y = mx + b
Where
y = y coordinate m = slope x = x coordinate b = y intercept
Choose any one pair of coordinates to find the y intercept. I will be using (2, -1)
y = mx + b
-1 = ( -3 / 5) (2) + b
-1 = -6 / 5 + b ( Don't forget to take the LCM)
-1 = -6/5 + 5b
-5+6 = 5b
1/5 = b
so the equation of line is
y = -3/5 x + 1/5
5y = -3x + 1
3x + 5y = 1
<h3>3/2b + 5 < 17</h3>
<em>We subtract 5 from both sides of the inequality.</em>
<h3>3/2b + 5 - 5 < 17 - 5</h3><h3>3/2 b < 12</h3>
<em>Multiply both sides by 2/3.</em>
<h3>( 2/3) * (3/2b) < (2/3) * 12</h3><h3>b < 8</h3>
<em>Therefore, the </em><em>correct option</em><em> is </em><em>alternative "A".</em>
<em>We would think that it is </em><em>option B,</em><em> but the only difference is that it changes the</em><em> direction of the sign.</em>
Subtract 6 from both sides (8n=40) then divide 40 by 8 (5) so n=5
A. x=1/8
b. x=0.025 same thing, just divide<span />
