3/6 of a minute because an hour is much longer
Answer:
(k/Df)-b = t
t=(k/Df)-b
Step-by-step explanation:
D = k/f(b+t)
k/D = f(b+t)
k/Df = b+t
(k/Df)-b = t
Answer:
Option D. All values of x make the equation true
Step-by-step explanation:
<u><em>The options of the question are</em></u>
a.The result is not correct because Step 2 has an error.
b.The solution is x=7.
c.No values of x make the equation true.
d.All values of x make the equation true
we have the equation
solve for x
Apply distributive property right side
Combine like terms
subtract 4x both sides
The equation has infinity solutions
.All values of x make the equation true
Answer:
<h2><em><u>7</u></em><em><u>.</u></em><em><u> </u></em><em><u><</u></em><em><u>B</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>129</u></em><em><u>°</u></em></h2><h2><em><u>8</u></em><em><u>.</u></em><em><u> </u></em><em><u><</u></em><em><u>N</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>85</u></em><em><u>°</u></em></h2>
Step-by-step explanation:
7. <A + <B = 180° <em>[</em><em>Since</em><em> </em><em>Co-interior</em><em> </em><em>angles</em><em>]</em>
=> 51° + <B = 180°
=> <B = 180° - 51°
=><em><u> <B = 129° (Ans)</u></em>
8. <M + <N = 180° <em> </em><em>[</em><em>Since</em><em> </em><em>Co-interior</em><em> </em><em>angles</em><em>]</em>
=> 95° + <N = 180°
=> <N = 180° - 95°
=> <em><u><N = 85° (Ans)</u></em>
Answer:
y = -2x+8
Step-by-step explanation:
First find the slope
m = ( y2-y1)/(x2-x1)
= ( -4-4)/(6-2)
= -8/4
= -2
The slope is -2
We can use the slope intercept form
y = mx+b where m is the slope and b is the y intercept
y = -2x +b
Using the point ( 2,4)
4 = -2(2) +b
4 = -4+b
Add 4 to each side
4+4 = -4+4+b
8 = b
y = -2x+8
