Answer:

Use the x method

Step-by-step explanation:

Move the 10 over to the other side and get x^2 - 3x -10 = 0 and solve by finding two numbers that add up to negative 3 but multiply to -10 which would be -5 and 2 so the binomials are (x-5)(x+2)

Answer:

x^2 - 3x = 10

Step-by-step explanation:

Move all terms to the left side.

Use the sum product pattern.

Factor (x-5)(x+2) = 0

Create two separate equations,

x - 5 = 0, and x + 2 = 0

Rearrange and isolate the variable.

x = 5

x = -2

Answer:

a=2

b=2

Step-by-step explanation:

This is a special 45-degree right triangle. Two angles equal 45 degrees, and then there is a right triangle. In these triangles, the hypotenuse is equal to [tex]k*\sqrt{2}[/tex] where k is equal to the legs (a and b). So, to find the legs divide [tex]k*\sqrt{2}[/tex] by [tex]\sqrt{2}[/tex]. This equals 2, and since a and b are congruent both a and b equal 2.

Answer:

150%

Step-by-step explanation:

Percent change =   [tex]\frac{New - Old}{|Old|}[/tex] × 100%

=> [tex]\frac{10000-4000}{4000}[/tex] × 100

=> [tex]\frac{6000}{4000}[/tex] × 100 = 150% (increase)

Answer:

x = 3.96

Step-by-step explanation:

The ratio for the big triangle is 5:6, so is likely the ratio for the smaller one.

3.3 x 6/5 = 3.96

6 / 3.96 =  1.51515151515

5 / 3.3 =  1.51515151515

Triangles are congruent.

Answer:

32589.77701

Step-by-step explanation:

1000000000=30683x+47872

x=1000000000-47872/30683

Therefore,x=32589.77701

Answer:

3, 20, 2, and 2.5

Step-by-step explanation:

For each question, they gave you an x and y value. If you substitute them into the equation and then solve for k, you get your answer.

On the first one, x is 12 and y is 1/4. If you put those into the equation they gave you y = k/x, you get 1/4 = k/12

3/12 is 1/4 so the first k is 3.

Second one y = k/x. x is 4 and is 5. So 5 = k/4

20/4 is 5, so the second k is 20.

Step-by-step explanation:

the guy above is correct

The graph that represents the given inequalities is required.

The required graph is attached.

The inequalities are

[tex]x^2+9y^2<81[/tex]

[tex]y^2+2<x[/tex]

Converting to general forms

Ellipse

[tex]\dfrac{x^2}{9^2}+\dfrac{9y^2}{9^2}<1\\\Rightarrow \dfrac{x^2}{9^2}+\dfrac{y^2}{3^2}<1[/tex]

So,

[tex]a=\pm9[/tex]

[tex]b=\pm3[/tex]

The vertices of the major axes are [tex](9,0)[/tex] and [tex](-9,0)[/tex]

The vertices of minor axes are [tex](0,3)[/tex] and [tex](0,-3)[/tex]

The center lies on the origin.

Since, the sign of the inequality is [tex]<[/tex] the shaded region will be inside the ellipse excluding the ellipse.

Parabola

[tex]x>1(y-0)^2+2[/tex]

So,

Vertex of parabola = [tex](2,0)[/tex]

Since, the square term is [tex]y^2[/tex] the axis of symmetry is the [tex]x[/tex] axis.

The parabola will open towards the positive x axis.

The shaded region is the area in the parabola excluding the parabola due to the [tex]>[/tex] sign.

Answer:

X≈ 70.5°

Step-by-step explanation:

Using the cosine rule in Δ XYZ

cos X = [tex]\frac{y^2+z^2-x^2}{2yz}[/tex]

with x = 22, y = 20, z = 18 , then

cos X = [tex]\frac{202+18^2-22^2}{2(20)(18)}[/tex]

          = [tex]\frac{400+324-484}{720}[/tex]

          = [tex]\frac{240}{720}[/tex] , then

∠ X = [tex]cos^{-1}[/tex] ([tex]\frac{240}{720}[/tex] ) ≈ 70.5° ( to the nearest tenth )
