Indicate in standard form the equation of the line passing through the given points.

Lynna [10]

(-2,2)(5,1)

slope(m) = (1 - 2) / (5 - (-2) = -1 / 7

y = mx + b
slope(m) = -1/7
use either of ur points....(5,1)....x = 5 and y = 1
now sub and find b, the y int
1 = -1/7(5) + b
1 = -5/7 + b
1 + 5/7 = b
7/7 + 5/7 = b
12/7 = b

equation is : y = -1/7x + 12/7....but we need it in standard form...

y = -1/7x + 12/7
1/7x + y = 12/7
x + 7y = 12 <== standard form

ratio of a rectangle's length to its width is 4:7. If the longer side is 31.5in., find the width, the perimeter, and the area of

Nikitich [7]

Answer:

Step-by-step explanation:

Ratio of length : width = 4 : 7

Length = 4x

Width = 7x

Longer side = 31.5 in

⇒ 7x = 31.5

Divide both sides by 7

x = 31.5/7

x = 4.5

length = 4x

= 4*4.5

l = 18 in

width = 31.5

w = 31.5 in

$\boxed{ \text {Perimeter of rectangle }= 2*l + 2*w}$

= 2*18 + 2*31.5

= 36 + 63

= 99 in

$\boxed{ \text{Area of rectangle = l*w}}$

= 18*31.5

= 567 in²

Which is better buy? 5 lb of flour for $0.90 or 8 lb for $1.25

Ludmilka [50]

Well let’s see if there’s a least common multiple of 5 and 8. Since 40 is the least common mult. We will multiply 40 x .90 and 40 x 1.25 . 40x.90 is 36 while 40x1.25 is 50. It’s better to buy eight pounds for 1.25!

Give the equation of the horizontal asymptote shown below.

Oxana [17]

Polynomial division yields

$\dfrac{7x^2}{x^2+5}=7-\dfrac{35}{x^2+5}$

As $x\to\pm\infty$ , you have the remainder term approaching $0$ , so the horizontal asymptote is the line $y=7$ .
