Write an equation in slope-intercept form of the line that passes through (-5, 19) and (5.13).

ruslelena [56]

Answer:

y=-3/5x+16

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(13-19)/(5-(-5))

m=-6/(5+5)

m=-6/10

simplify

m=-3/5

y-y1=m(x-x1)

y-19=-3/5(x-(-5))

y-19=-3/5(x+5)

y=-3/5x-15/5+19

y=-3/5x-3+19

y=-3/5x+16

The height of a triangle is 4 m less than its base. The area of the triangle is 48 m².What is the length of the base?

yaroslaw [1]

Triangle Area = .5 * base * height

48 = .5 * (x +4) * x

48 = (.5x + 2) * x

48 = .5x^2 + 2x

.5x^2 + 2x -48 = 0

x = 8

base = 12

an article after allowing a discount of 20% on its marked price was sold at a gain of 20% had it been sold after allowing 25% di

Effectus [21]

Answer:

Rs 120

Step-by-step explanation:

Let MP = m

Discount = 25% of MP = m/4

SP = MP - Discount

= m - m/4 = 3m/4

If profit is 20%, CP = 3m/4 x 100/120 = 5m/8

=> Profit = 3m/4 - 5m/8 = m/8

Given Profit - Discount = Rs 15

=> |m/8 - m/4| = 15

m/8 = 15

m = Rs 120

$30x^2=2\times 3\times 5\times x^2$

$66x^5=2\times 3\times 11\times x^5$

The greatest common factor is the product of the least powers of the common factors.

The GCF is
