use the substitution method

since y = 6 fill in 6 for y in y = -5x + 21

6 = -5x + 21

subtract 21 from both sides

-15 = -5x

divide each side by -5

3 = x

Answer:

226.2

Step-by-step explanation:

I took the test. I hope this helps! :)

The area of the circular lace is required.

The smallest circular piece of lace to cover the entire top of the table is 226.2 inches².

Length of each side of square = 12 inches

The diameter of the circle will be the length of the diagonal of the square from the given figure.

[tex]d=\sqrt{12^2+12^2}\\\Rightarrow d=12\sqrt{2}\ \text{in}[/tex]

Area of a circle is given by

[tex]A=\pi\dfrac{d^2}{4}\\\Rightarrow A=\pi \dfrac{(12\sqrt{2})^2}{4}\\\Rightarrow A=226.194\approx 226.2\ \text{in}^2[/tex]

Answer:

The acceleration of an object varies directly as the force acting on it. If a force of 240 newtons causes an acceleration of 150 m/s², what force will cause an acceleration of 100 m/s?? 2. The stretch in a loaded spring varies directly as the load it supports.

Answer:

160 Newtons

Step-by-step explanation:

240÷150= 1.6. 100x1.6 gives us the answer which is 160 Newtons for 100m/s. For every 1.6 newtons,1 m/s is gained.

Answer:

z = 5

Step-by-step explanation:

[tex]\frac{4x^2y^7}{8x^3y^2} = \frac{y^z}{2x}[/tex]

It can be also written as -

[tex]\frac{2^2 \times x^2 \times y^7}{2^3 \times x^3 \times y^2} = \frac{1 \times x^0 \times y^z}{2 \times x^1 \times y^0}[/tex]

Using law of exponents , lets solve this.

[tex]=> 2^{(2-3)} \times x^{(2-3)} \times y^{(7 - 2)} = \frac{1}{2} \times x^{(0-1)} \times y^{(z-0)}[/tex]

[tex]=> 2^{-1} \times x^{-1} \times y^{5} = 2^{-1} \times x^{-1} \times y^z[/tex]
