What is the slope of a line that passes through the points (4,-2) and (-1,8)

Mathematics
1 answer:
gregori [183]2 years ago
6 0

set y = kx+b

for (4,-2): -2=4k+b (function 1)

for (-1,8): 8=-k+b (function 2)

Use function 2 subtract function 1:

10=-5k

k=-2

SO the slope is -2.

5. Find the value of x that makes BC || DE.
s344n2d4d5 [400]

Answer:

x = -7

Step-by-step explanation:

To find the value of x, you need to set up a proportion:

\frac{x-2}{15} = \frac{x-1}{18}

Then cross multiply:

15x - 15 = 18x + 36

Then subtract 15x from both sides:

-15 = 3x + 36

Subtract 36 from both sides:

-51 = 3x

Finally, divide both sides by 3:

x = -7

PLEASE HELP QUICKLY! 20 points! I will mark best answer as Brainliest!
Alina [70]

t= 2.25 secs

Step-by-step explanation:

Step 1 :

Equation for motion with uniform acceleration is v = u+ at

where v is the final velocity

          u is the initial velocity

          a is the acceleration due to gravity

          and t is the time

Step 2 :

Here , v = 0 because at the highest point final velocity is 0.

u = 72 feet/sec

a = -32 ft/sec^2

We need to find the time t.

Substituting in the equation we have,

0 = 72 -32 * t

=> 32 t = 72

=> t = 72/32 = 2.25 secs
