Answer:

y = -7.2x + 540

Step-by-step explanation:

to find the slope I used the x-and-y intercepts: (0, 540) and (75, 0)

slope = 540/-75 or -7.2

Answer:

Slope (m) =ΔY /ΔX =-3/ 1 =-3

n slope = -3

From equation [<u>-2</u>x-8]

m slope = -2

so B) m>n

A florist prepares an order of daisies and roses. For every 5 daisies she orders 2 roes. What 2 equations show the relationship

Vsevolod [243]

Answer:

$d = 2.5r$ and $r = \frac{d}{2.5}$

Step-by-step explanation:

Given

5 daises to 2 roses

Required

Determine the relationship between them

The question shows a direct proportion between number of daises and roses.

i.e.

$d\ \alpha\ r$

Where d = daises and r = roses

Convert the above expression to an equation

$d = kr$

Make k the subject

$k = \frac{d}{r}$

When d = 5 and r = 2;

$k = \frac{5}{2}$

$k = 2.5$

So, the first relationship between d and r can be gotten by substituting 2.5 for k in d = kr

So:

$d = 2.5 * r$

$d = 2.5r$ ----------- (1)

Make r the subject in (1)

$r = \frac{d}{2.5}$ ------------------------(2)

Hence, the relationships between d and r are:

$d = 2.5r$ and $r = \frac{d}{2.5}$

2(4x - 1) < 4(3x+1), where x ∈ {set of all negative Integers}

alexgriva [62]

$\large\underline{\sf{Solution-}}$

Given inequation:

$\sf 2(4x-1)$

$\sf\longmapsto 8x-2$

$\sf\longmapsto 8x-2-4$

$\sf\longmapsto 8x-6$

$\sf\longmapsto 8x-6-8x$

$\sf\longmapsto -6$

$\sf\longmapsto 4x>-6$

$\sf\longmapsto \dfrac{4x}{4}>\dfrac{-6}{4}$

$\sf\longmapsto x >-1\dfrac{1}{2}$

Therefore:

$\sf\longmapsto\boxed{ x=\{-1\}}\ \ Ans.$

HELP!! IM VERY CONFUSED ON HOW TO DO THIS!!

dusya [7]

Answer:

The side length of the equilateral triangle 9 inches.

The side length of the hexagon 4.5 inches.

The side length of the equilateral triangle = 1.4x + 2

So, the perimeter = 3(1.4x + 2) = 4.2x + 6.

The side length of the hexagon = 0.5x + 2

So, the perimeter = 6(0.5x + 2) = 3x + 12.

Given the the perimeters are equal.

So,

Hence,

The side length of the equilateral triangle = 1.4x + 2 = 1.4(5) + 2 = 9

The side length of the hexagon = 0.5x + 2 = 0.5(5) + 2 = 4.5
