Answer:

[tex](x,y) = (1,-12)[/tex]

Step-by-step explanation:

Given

[tex]y = 6x - 18[/tex]

Required

Find a solution

To do this, we assume a value for x, then solve for y.

Let x = 1

Substitute 1 for x in [tex]y = 6x - 18[/tex]

[tex]y = 6*1 - 18[/tex]

[tex]y = 6 - 18[/tex]

[tex]y= -12[/tex]

Hence, a solution is:

[tex](x,y) = (1,-12)[/tex]

Answer:

[tex]8x + 32 + 116 = 180 \\ 8x + 148 = 180 \\ 8x = 180 - 148 \\ 8x =32 \\ \boxed{x = 4}[/tex]

[tex](7x + 5) + 52 + 67 = 180 \\ 7x + 124 = 180 \\ 7x = 56 \\ \boxed{x = 8}[/tex]

Answer:

a) side length z = 19.965 ≅ 20m

b) angle 'd' = 53.13°

Step-by-step explanation:

Step(i):-

Given that ∠HIG is a right angle triangle

Given∠I = 53°

By using the sine function

[tex]sin53 = \frac{opposite side}{hypotenuse} =\frac{z}{25}[/tex]

 z = 25 × sin53° = 25×0.798635

z = 19.965 ≅20 m

Step(ii):-

[tex]sind = \frac{8}{10} = \frac{4}{5}[/tex]

⇒    [tex]d = sin^{-1} (\frac{4}{5} )[/tex]

⇒   d = 53.13°

Final answer:-

a) side length z = 19.965 ≅ 20m

b) angle 'd' = 53.13°

Answer:

0.1538

Step-by-step explanation:

There are 8 cards that are either 2s or Ks.

P(2 or K) = 0.1538

Answer:

The minimum cost per unit is obtained for an order of 8 units.

Step-by-step explanation:

Since the total cost is modeled by;

C(x)=5x²+320

Then;

1 unit costs; C(x)=5(1)²+320 = 325

cost per unit 325/1 = 325

8 units costs; C(x)=5(8)²+320 = 640

cost per unit = 640/8 = 80

80 units costs; C(x)=5(80)²+320 = 32320

Cost per unit = 32320/80 = 404

The minimum cost per unit is obtained for an order of 8 units.

Answer:

Angle GHI measures 56º, and angle JKL measures 34º.

Step-by-step explanation:

Complementary Angles:

If two angles are complementary, the sum of their measures is 90º.

∠GHI is (5x+6)∘ and ∠JKL measures (3x+4)∘.

Since they are complementary:

[tex]5x + 6 + 3x + 4 = 90[/tex]

[tex]8x + 10 = 90[/tex]

[tex]8x = 90 - 10[/tex]

[tex]8x = 80[/tex]

[tex]x = \frac{80}{8}[/tex]

[tex]x = 10[/tex]

Measures:

GHI: 5*10 + 6 = 50 + 6 = 56º

JKL: 3*10 + 4 = 30 + 4 = 34º.

Angle GHI measures 56º, and angle JKL measures 34º.

The measures of the two angles are 56 and 34 degrees

The sum of complementary angles is 90degrees

Given the measurement:

Taking the sum and equating to 90 degrees

5x + 6 + 3x + 4 = 90

8x + 10 = 90

8x = 90 - 10

8x = 80

x = 10

∠GHI = 5(10) + 6

∠GHI = 56 degrees

∠JKL = 90 - 56

∠JKL = 34degrees

Hence the measures of the two angles are 56 and 34 degrees

Answer:

[tex]KH = 55[/tex]

Step-by-step explanation:

Given

See attachment

Required

Find KH

From the attachment:

[tex]GD = 13[/tex]   [tex]DE = 7[/tex]

[tex]HI = 29.4[/tex]

To find KH, we make use of the following equivalent ratio:

[tex]GD : DE = KH : HI[/tex]

Substitute values for GD, DE and HI

[tex]13 : 7 = KH : 29.4[/tex]

Convert to fractions

[tex]\frac{13}{7} = \frac{KH}{29.4}[/tex]

Make KH the subject

[tex]KH = \frac{13}{7} * 29.4[/tex]

[tex]KH = \frac{13* 29.4}{7}[/tex]

[tex]KH = \frac{382.2}{7}[/tex]

[tex]KH = 54.6[/tex]

[tex]KH = 55[/tex] --- approximated

x = 3

Answer:

x = 1 and x = -10/11

Step-by-step explanation:

3x² + 8x² - x - 10 = 0

11x² - x - 10 = 0

(11x + 10)(x - 1) = 0

11x + 10 = 0

11x = -10

x = -10/11

x - 1 = 0

x = 1

Answer:

13/21

Step-by-step explanation:

find common denominator 21

Monday 2/7 = 6/21

Tuesday 1/3 = 7/21

multiply the top by what you did the bottom for the common denominator to get the equivalent fraction

add the two fraction together by keeping the denominator the same

6+7=13

so 13/21

Answer:

a) Area = 2x^2 + 3x - 2

b) Perimeter = 64x + 28

c) Length = 60 feet and Width = 50 feet

Step-by-step explanation:

The computation is shown below:

Given that

length = 12x + 24 feet

And, the width be 20x - 10 feet

Now as we know that

Area of the rectangle = length × width

= (12x + 24) × (20x - 10)

= 12x (20x -10) + 24(20x - 10)

= 240x^2 - 120x + 480x - 240

= 240x^2 + 360x - 240

= 2x^2 + 3x - 2

Now for perimeter

As we know that

Perimeter of the rectangle = 2(Length + width)

= 2(12x + 24 + 20x - 10)

= 2(32x + 14)

= 64x + 28

In the case when the perimeter is 220

So,

220 = 64x + 28

64x = 220 - 28

64x = 192

x = 3

Now length is 12(3) + 24

= 36 + 24

= 60 feet

And, the width is

= 20(3) - 10

= 60 - 10

= 50 feet
