Answer:

x > 12

Step-by-step explanation:

so the question ask is the x = 14 (yes)

x = 17 (yes)

x = 7 (no) [ bcs the number of x is bigger than 12 not smaller than 12]

x = 12 (no) [ bcs the number of x is bigger than 12 not equal 12]

Answer:

1. yes

2. yes

3. no

4. no

Step-by-step explanation:

Replace x by each value of x.

x+32>44

1. yes

14+32>44\\46>44

2. yes

17+32>44\\49>44

3. no

7+32>44\\39>44

4. no (this is not a solution because the value must be greater than 44 not equal to)

Find the constant of proportionality k. Then write an equation for the relationship between x and y
ExtremeBDS [4]

Question:

Find the constant of proportionality k. Then write an equation for the relationship between x and y

\begin{array}{ccccc}x & {2} & {4} & {6} & {8} \ \\ y & {10} & {20} & {30} & {40} \ \ \end{array}

Answer:

(a) k = 5

(b) y = 5x

Step-by-step explanation:

Given

\begin{array}{ccccc}x & {2} & {4} & {6} & {8} \ \\ y & {10} & {20} & {30} & {40} \ \ \end{array}

Solving (a): The constant of proportionality:

Pick any two corresponding x and y values

(x_1,y_1) = (2,10)

(x_2,y_2) = (6,30)

The constant of proportionality k is:

k = \frac{y_2 - y_1}{x_2 - x_1}

k = \frac{30-10}{6-2}

k = \frac{20}{4}

k = 5

Solving (b): The equation

In (a), we have:

(x_1,y_1) = (2,10)

k can also be expressed as:

k = \frac{y- y_1}{x- x_1}

Substitute values for x1, y1 and k

5 = \frac{y- 10}{x- 2}

Cross multiply:

y - 10 = 5(x - 2)

Open bracket

y - 10 = 5x - 10

Add 10 to both sides

y - 10 +10= 5x - 10+10

y = 5x

Answer:

y=-2/3 x +4

Step-by-step explanation:

slop = (6-0)/(-3-6)= -2/3

c= 4  (when x =0)

line equation:

y= mx + c

y=-2/3 x +4
