This is only one equation. It is therefore not a system and you can not solve for two different variables y and z unless you have another equation to solve with. It.

Please hurry<br><br> What is the surface area of the cylinder? Express the answer in terms of pi.

➷ The formula for surface area of a cylinder is:

$2\pi rh + 2\pi r^2$

The radius is half the diameter

radius = 8/2 = 4

Substitute the values in:

$2\pi (4)(18) + 2\pi (4)^2$

Solve it:

surface area = $176\pi$

What is the sum of the solutions to (x − 6)(x + 0.7) = 0 ?

Nonamiya [84]

Answer:

5.3

Step-by-step explanation:

(x − 6)(x + 0.7) = 0

using the zero product property

x-6=0 x+.7 =0

x-6+6 = 0+6 x+.7 -.7 = 0-.7

x = 6 x= -.7

sum of the solutions

6+-.7 = 5.3

Graph y > -1/3x+5<br><img src="https://tex.z-dn.net/?f=y%20%3E%20%20-%20%20%5Cfrac%7B1%7D%7B%203%20%7D%20x%20%2B%205" id="Tex

Explanation:

The function is $y>-\frac{1}{3} x+5$

To graph the function, let us find the x and y intercepts.

To find x-intercept, let us substitute y=0 in the function $y>-\frac{1}{3} x+5$

$\begin{aligned}0 &=-\frac{1}{3} x+5 \\-5 &=-\frac{1}{3} x \\x &=15\end{aligned}$

Thus, the x-intercept is $(15,0)$

To find the y-intercept, let us substitute x=0, we get,

$\begin{aligned}&y=-\frac{1}{3}(0)+5\\&y=5\end{aligned}$

Thus, the y-intercept is $(0,5)$

The graph has no asymptotes.

To plot the points in the graph, we need to substitute the values for x in the function $y>-\frac{1}{3} x+5$ , to find the y-values.

The points are $(-2,5.667),(-1,5.333),(1,4.667),(2,4.333),(3,4)$ . The image of the graph and table is attached below:
