Answer:
-0.25
Step-by-step explanation:
-8= 2/x
multiply both sides by x -> -8x =2
divide both sides by -8 -> x=2/-8
Ans= -1/4 = -0.25
One way is to graph it and do the vertical line test
it is not a function if we can draw a vertical line in the graph that passes through 2 points of the graph
if we graph this function, we see there is no place we can draw a vertical line and hit the line twice
Answer:
Jimmy has a ratio of 1:20, or 1 page:20 seconds. Carlo has a ratio of 1:30, or 1 page:30 seconds. Jimmy reads at a faster pace than Carlo, as he is able to read a page in 2/3 of the time it takes Carlo.
Step-by-step explanation:
Jimmy reads a page, on average, every 20 seconds.
5 × 60 = 300
300/15 = 20
therefore, one page every 20 seconds
1:20
Carlo reads a page, on average, every 30 seconds.
6 × 60 = 360
360/12 = 30
therefore, one page every 30 seconds
1:30
Answer:
1
Step-by-step explanation:
<h2>Given, y = b m x m</h2><h2>y' = -b m x (m+1)</h2><h2>At any point (x1,y1)</h2><h2 /><h2>Equation of tangent is given by </h2><h2>y - y1 </h2><h2>------- = -b m x1 -(m+1)</h2><h2>x - x1</h2><h2>Y intercept = - m</h2><h2>X intercept = (m-1) × 1</h2><h2> m </h2><h2>Area bounced = 1 (m - 1)×1</h2><h2> ---- ---------------------- x m</h2><h2> 2 m</h2><h2>For area to be constant, m = 1</h2>
Hi,
Work:
Equation;
Roots: (-9, 0), (8, 0)
Domain: x = R
Minimum: (-1/2, -289/4)
Vertical intercept: (0, -72)
Hope this helps.
