You need to come up with an array of answers for x and y that will be greater than 0.
x+4y>0. example if x is -1 and y is 1 will this be correct.
-1+(4*1)>0, -1+4>0. 3>0? Yes
if x is 1 and y is -1 then the equation becomes 1+(-4)>0 -3 is not>0 so it's not in the array
x could be -3 and y 1
You will plot a line to show all the answers.

Identify the slope, y intercept and x intercept of the graph of the linear equation. y = -3x +9
Alja [10]

Answer:

Slope: -3

Y intercept: (0, 9)

X intercept: (3, 0)

Step-by-step explanation:

In the equation y = mx + b, m is the slope and b is the y intercept.

Since the equation is y = -3x + 9, m is -3 and 9 is the y intercept.

So, the slope is -3 and the y intercept is at (0, 9)

To find the x intercept, plug in 0 as y and solve for x:

y = -3x + 9

0 = -3x + 9

-9 = -3x

3 = x

So, the x intercept is at (3, 0)

Find the surface area of the composite solid. Leave your answer in terms of pi.
bonufazy [111]
Total surface area = lateral area of cone + lateral area of cylinder + area of base of cylinder:
cone: πrL = π(5cm)(13cm) = 65πcm²
cylinder: 2πrh = 2π(5cm)(12cm) = 120πcm²
base: πr² = π(5cm)² = 25πcm²
total surface area = 65πcm² + 120πcm² + 25πcm² = 210πcm²

What is 5.5-x=-4.5-x
konstantin123 [22]
<h3>Simplifying </h3>

5.5 + -1x = -4.5 + -1x

<h3> Add 'x' to each side of the equation. </h3>

5.5 + -1x + x = -4.5 + -1x + x

<h3> Combine like terms: </h3>

-1x + x = 0

5.5 + 0 = -4.5 + -1x + x

5.5 = -4.5 + -1x + x

<h3> Combine like terms:</h3>

-1x + x = 0

5.5 = -4.5 + 0

5.5 = -4.5

<h3> Solving: </h3>

5.5 = -4.5

<h3> This equation is invalid, the left and right sides are not equal, therefore there is no solution.</h3><h3 />

Hope this helps!
