Find the x and y intercept of the line -10x-6y=120

Ipatiy [6.2K]

ANSWER

The x intercept is

$(-12,0).$

The y intercept is
$(0, - 20).$

EXPLANATION

The equation of the given line is

$- 10x - 6y = 120$

At x-intercept
$y = 0$

We substitute this y value to obtain the corresponding x value.

This implies that,

$- 10x - 6(0)= 120$

$- 10x - 0 = 120$

$- 10x = 120$

We divide both sides by -10 to get,

$x = - 12$
The x-intercept is

$(-12,0).$

At y-intercept also,
$x = 0$

We substitute this value of x into the equation to find the corresponding y-value.

This implies that,

$- 10(0) - 6y = 120$

$- 0- 6y = 120$

$- 6y = 120$

We divide through by -6 to get,

$y = - 20$

The y-intercept is
$(0,-20).$

Recall the scenario about Eric's weekly wages in the lesson practice section. Eric's boss have been very impressed with his work

Alona [7]

Answer:

$1)\quad f(x)=\bigg\{\begin{array}{ll}12x&0\leq x$

2) D: x = [0, 24]

3) R: y = [0, 384]

4) see graph

Step-by-step explanation:

Eric's regular wage is $12 per hour for all hours less than 9 hours.

The minimum number of hours Eric can work each day is 0.

f(x) = 12x for 0 ≤ x < 9

Eric's overtime wage is $18 per hour for 9 hours and greater.

The maximum number of hours Eric can work each day is 24 (because there are only 24 hours in a day).

f(x) = 18(x - 8) + 12(8)

= 18x - 144 + 96

= 18x - 48 for 9 ≤ x ≤ 24

The daily wage where x represents the number of hours worked can be displayed in function format as follows:

$f(x)=\bigg\{\begin{array}{ll}12x&0\leq x$

2) Domain represents the x-values (number of hours Eric can work).

The minimum hours he can work in one day is 0 and the maximum he can work in one day is 24.

D: 0 ≤ x ≤ 24 → D: x = [0, 24]

3) Range represents the y-values (wage Eric will earn).

Eric's wage depends on the number of hours he works. Use the Domain (given above) to find the wage.

The minimum hours he can work in one day is 0.

f(x) = 12x

f(0) = 12(0)

= 0

The maximum hours he can work in one day is 24 (although unlikely, it is theoretically possible).

f(x) = 18x - 48

f(24) = 18(24) - 48

= 432 - 48

= 384

D: 0 ≤ y ≤ 384 → D: x = [0, 384]

4) see graph.

Notice that there is an open dot at x = 9 for f(x) = 12x

and a closed dot at x = 9 for f(x) = 18x - 48

The painting by itself is a rectangle with length 20 cm and width 16 cm. The painting and frame together form a larger rectangle

11Alexandr11 [23.1K]

Answer:

The area of frame is 180 square meters.

Step-by-step explanation:

We are given the following in the question:

Dimension of rectangular painting:

Length, l = 20 cm

Width, w = 16 cm

Dimension of frame:

Length, L = 25 cm

Width, W = 20 cm

We have to find the area of frame.

Area of rectangle =

$A = l\times w$

Area of frame =

$A-a\\=(L\times W)-(l\times w)\\=(25\times 20)-(20\times 16)\\=180\text{ square meters}$

Thus, the area of frame is 180 square meters.
