What is the equation of the line that passes through the point(-8,1) and has a slope of -3/4​

Mathematics

vodka [1.7K]2 years ago
7 0

Answer:

slope = -3/4

using the formula

y -y1 = m(x -x1)

y -1 = -3/4(x -(-8))

y -1 = -3/4(x +8)

cross multiply

4(y -1) = -3(x +8)

4y -4 = -3x -24

4y = -3x -24 +4

4y = -3x -20

divide both sides by 4

y = -3/4 x -5 (equation of the line)

Find the volume of this square<br> based pyramid.<br> 10 cm<br> 8 cm<br> 8 cm<br> V = [?] cm3
oksano4ka [1.4K]

Answer:

213.3

Step-by-step explanation:

The volume of a pyramid is 1/3 base times height.

Using this formula, our square base is 8*8, or 64 square units.

Multiplying that by the height, 10. We get 64*10, 640.

Finally dividing by 3, we have 213.3333333333...

Rounding that to the nearest tenth, 213.3.

Suppose a certain outlet chain selling appliances has found that for one brand of stereo system, the monthly demand is 240 when
Doss [256]

Answer: Therefore the demand function can be given as;

q = -3/2p + 1590

Step-by-step explanation:

Given that at;

$900 the monthly demand is 240. ....1

$850 the monthly demand is 315. ....2

Since, the function is a linear function. The demand function would be of the form;

q = mp + c ....5

Where q = quantity demanded

p = price m = slope and c = intercept

Substituting conditions 1 and 2 to the equation.

240 = 900m + c. ...3

315 = 850m+ c ...4

Subtracting eqn 4 from 3

-75 = 50m

m = -75/50

m = -3/2

Substituting m = -3/2 into equation 3;

We have,

240= -3/2(900) + c

c = 240 + 3/2(900)

c = 1590

Therefore the demand function can be given as; substituting m and c into equation 5, we have;

q = -3/2p + 1590

Given f(x) = -3x + 21, find x when f(x) = 6.
Ainat [17]

Answer:

x = 5

Step-by-step explanation:

Given

f(x) = - 3x + 21 and f(x) = 6, then equating gives

- 3x + 21 = 6 ( subtract 21 from both sides )

- 3x = - 15 ( divide both sides by - 3 )

x = 5
