Complete the solution of the equation. find the value of y when x equals 1. <br><br>9x +7y= -12

Taya2010 [7]

Answer:

$y=-3$

Step-by-step explanation:

Given Equation:

$9x +7y=-12\\$ y=? at x= 1

Putting the given value of 'x' in the equation:

$9(1) +7y=-12\\\\9+7y=-12\\\\7y=-12-9\\\\7y=-21\\\\y=-\frac{21}{7} \\y=-3$

At $x=1$ , the value of y is $y=-3$

Step-by-step explanation:

Volume of a cylinder is:

V = πr²h

V = (3.14) (4 in)² (5 in)

V = 251.2 in³

Volume of a cone is:

V = ⅓ πr²h

V = ⅓ (3.14) (4 in)² (15 in)

V = 251.2 in³

The volumes are equal.

5. Find the surface area of the cone. Round to<br> the nearest hundredth.<br> 2 ft<br> 6 ft

den301095 [7]

Answer:

$52.3m^2$

Step-by-step explanation:

Use these formulas

$A=\pi rl+\pi r^2\\l=\sqrt{r^2+h^2}$

Now solve

$A=\pi r(r+\sqrt{h^2+r^2} )\\=\pi *2*(2\sqrt{6^2+2^2} )\\=52.3m^2$

Solve for the x <br> (Round to the nearest hundred)

stiks02 [169]

Answer:

17.97=x

Step-by-step explanation:

tan theta = opposite side/ adjacent side

tan 38 = x /23

Multiply each side by 23

23 * tan 38 = x/23 * 23

23 tan 38 = x

17.96956941 =x

To the nearest hundredth

17.97 =x
