1. ratio = 2 c of dressing / 4 lb of vegetables

Use two variables: d for the number of c of dressing and v for the number of pounds of vegetables.

Then d / v = 2/4 = 1/2 => d = v/2

Now you can make a table

v d

2 1

4 2

6 3

8 2

And you can draw a line for the points (2,1); (4,2); (6,3), (8,4) ... the slope of the graph is the ratio = 1/2

b) I already did it above as part ot the explanation: d/v = 1/2

(a) The model for the ratio of dressing and vegetables is the given by the equation

$\rm\bold{ V = 2D}$

A catering company’s recipe for salad uses a ratio of 2 c of dressing 4 lb of vegetables.

(a) We have to draw a model for the ratio.

(b) We have to write the ratio of dressing to vegetables as a reduced fraction.

Dressing = 2c

Vegetables = 4lb

The ratio of both is formulated as 2c : 4lb

(a) Let us consider dressing is represented by D and amount of vegetables is represented by V then we can say that

$\rm \dfrac{D}{V} = \dfrac{2}{4} = \dfrac{1}{2}$

hence when D increases by 1 unit variable V increases by two units and hence we can write

$\rm V = 2D.....(1)$

The V and D values are shown in the table below

V D

1 2

2 4

3 6

Equation (1) represents the model for the given situation.

(b) The ratio of dressing to vegetables as a reduced fraction is given by

$\rm \dfrac{D}{V} = \dfrac{1}{2}$

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = $\frac{-8+3}{4-7}$ = - $\frac{5}{3}$

y = - $\frac{5}{3}$ x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - $\frac{20}{3}$ + c ⇒ c = - $\frac{4}{3}$

y = - $\frac{5}{3}$ x - $\frac{4}{3}$ ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form

Consider this equation. |y + 6| = 2 what can be concluded of the equation? check all that apply. there will be one solution. there will be two solutions. the solution to –(y + 6) = 2 will be also be a solution to the given absolute value equation. the solution(s) will be the number(s) on the number line 2 units away from –6. the value of y must be positive since the variable is inside absolute value signs.
