Find the equation lines (4, 5)(7, 3)

Mathematics

Step-by-step explanation:

Hey there!

The equation of a st.line passing through points (4,5) and (7,3) is;

(y - y1) =  \frac{y2 - y1}{x2 - x1} (x - x1)

<u>Put</u><u> </u><u>all values</u><u>. </u>

<u>(y - 5) =  \frac{3 - 5}{7 - 4} (x - 4)</u>

<u>Simplify</u><u> </u><u>it</u><u>. </u>

<u>(y - 5) =  \frac{ - 2}{3} (x - 4)</u>

<u>3(y - 5) =  - 2x + 8</u>

<u>3y - 15 =  - 2x + 8</u>

<u>2x + 3y - 23 = 0</u>

<u>Therefore the</u><u>required</u><u> </u><u>equation</u><u> </u><u>is</u><u> </u><u>2</u><u>x</u><u>+</u><u>3</u><u>y-23</u><u>=</u><u>0</u><u>.</u>

<em><u>Hope it helps</u></em><em><u>.</u></em><em><u>.</u></em>

Paul went on a bike ride of 30 miles. He realized that if he had gone 8 mph faster, he would have arrived 12 hours sooner. How f
lara [203]

Answer: He actually rode 2 miles per hour on his trip

Step-by-step explanation: Maybe unconventional, but express the time it took, then figure the speed.

Time  = distance /speed  t will represent time, s is the speed:  t = 30/s Use the rime it would have taken at the higher speed to create an equation:

t-12 = 30/s+8   replace the y with the 30/s

30/s -12 = 30/s+8

(s)(30/s -12 ) = (s)(30/s+8 )  Cross multiply to cancel denominators  

(s-8)(30 -12s) = (s-8)(30s/s+8 ) ==> 30s +240 -12s² -96s =30s   Simplify:  

(-1)(-12s² -96s +240 ) =0 ==>  12s² +96s -240  divide all by 12

s² + 8s -20 = 0   Factor and solve for s

(s +10)(s -2) =0    s-2=0   S= 2  

Proof:

30/2 = 15 hours for original trip at 2mph,  

increase speed by 8mph   2 + 8 = 10mph

30 miles at 10mph takes 3 hours; that is 12 hours less than his actual trip.

Answer:

33.49 cubic units

Step-by-step explanation:

V_{sphere}  =  \frac{4}{3}  \times  \pi {r}^{3}  \\  \\ V_{sphere}  =  \frac{4}{3}  \times  \pi {(2)}^{3}  \\  \\  V_{sphere}  =  \frac{4}{3}  \times  \pi  \times 8 \\  \\ V_{sphere}  =  \frac{32 \times 3.14}{3}  \\  \\ V_{sphere}  =  \frac{100.48}{3}  \\  \\ V_{sphere}  = 33.4933333\\  \\ V_{sphere}   \approx 33.49\: units^3
