Solve the following equation for x.
3x - 9 = -42

Solve The Following Equation For X.3x - 9 = -42

Answers

Answer 1

Answer:

x = -11

Step-by-step explanation:

Add 9 to both sides of the equation

3 − 9 = −42

3 − 9 + 9 = −42 + 9

Simplify

Add the numbers

3 = −33

Divide both sides of the equation by the same term

3 = −33

3/3 = −33/3

Simplify

Cancel terms that are in both the numerator and denominator

Divide the numbers

= −11

Answer:

17m

Step-by-step explanation: Cut the triangle in half and place it over the other triangle creating a square. We know that one side is 3m so since all the sides of a square are equal 3 times 3 equals to 9. For the rectangle 2 times 4 is 8. So finally 8 plus 9 equals to 17. The area of the composite figure is 17m.

Answer:

Horizontal distance = 0 m and 6 m

Step-by-step explanation:

Height of a rider in a roller coaster has been defined by the equation,

y = [tex]\frac{1}{3}x^{2}-2x+8[/tex]

Here x = rider's horizontal distance from the start of the ride

i). [tex]y=\frac{1}{3}x^{2}-2x+8[/tex]

      [tex]=\frac{1}{3}(x^{2}-6x+24)[/tex]

      [tex]=\frac{1}{3}[x^{2}-2(3x)+9-9+24][/tex]

      [tex]=\frac{1}{3}[(x^{2}-2(3x)+9)+15][/tex]

      [tex]=\frac{1}{3}[(x-3)^2+15][/tex]

      [tex]=\frac{1}{3}(x-3)^2+5[/tex]

ii). Since, the parabolic graph for the given equation opens upwards,

    Vertex of the parabola will be the lowest point of the rider on the roller coaster.

    From the equation,

    Vertex → (3, 5)

    Therefore, minimum height of the rider will be the y-coordinate of the vertex.

    Minimum height of the rider = 5 m

iii). If h = 8 m,

    [tex]8=\frac{1}{3}(x-3)^2+5[/tex]

    [tex]3=\frac{1}{3}(x-3)^2[/tex]

    (x - 3)² = 9

    x = 3 ± 3

    x = 0, 6 m

    Therefore, at 8 m height of the roller coaster, horizontal distance of the rider will be x = 0 and 6 m

Try using PhotoMath that should help you:)

Answer:

44° , acute angle

Step-by-step explanation:

Given

y = 8x + 12 ← substitute x = 4

y = 8(4) + 12 = 32 + 12 = 44°

Since 44° < 90° then angle y is acute

Mia and Mario specialize in producing the item in which she or he has a comparative advantage. Then they trade one pasta dish for one pizza.. Before specialization and​ trade, Mia and Mario produce 6 dishes of pasta and 6 pizzas an hour each. The total gains from specialization and trade are​ ___________

Answers

Answer:

6 pizza, 6 pasta

Step-by-step explanation:

Now from the question we can see that Mia has comparative advantage in Pasta production and Mario in Pizza production.

Now before they both specialized, Mia's production was 6 pizza, 6 pasta. Mario also was making 6 pasta, 6 pizza.

So in total both were making 12 pizza and 12 pasta.

After they had specialized, Mario's pizza production is 18 pizza and Mia's pasta production is 18 pasta.

So we have that mia is producing 6 more pizza, 18-12 = 6

and Mario is also producing 6 more pasta.

So there is net gain of 6 pizza and 6 pasta.
