X>-3 that’s the answer but it says i need 20 characters so just ignore this lol
Answer:
C = 18
Step-by-step explanation:
Put the numbers in place of their symbols and do the arithmetic. The diagram is showing you r = 3.
C = 2πr
C = 2(3)(3) . . . . . using 3 for π, as directed
C = 18
Given equation : -6x+3y=18.9.
We need to find x and y-intercepts.
<em>In order to find the x-intercept, we need to plug y=0 and solve the equation for x.</em>
Plugging x=0 in given equation, we get
-6(0)+3y=18.9
0 +3y = 18.9
3y = 18.9
Dividing both sides by 3, we get
y = 6.3
<em>In order to find the y-intercept, we need to plug x=0 and solve the equation for y.</em>
Plugging y=0 in given equation, we get
-6x+3(0)=18.9
-6x = 18.9
Dividing both sides by -6, we get
x = -3.15.
<h3>Therefore, x-intercept is -3.15 and y-intercept is 6.3.</h3>
We could write them as coordinates
<h3>x-intercept (-3.15, 0) </h3><h3>y-intercept (0, 6.3).</h3>
The perimeter is 6x + 12, and a model example is attached.
All three sides of an equilateral triangle are the same, so multiply the side length by 3 to find the perimeter.
3(2x + 4)
Now distribute the 3.
3 * 2x + 3 * 4
6x + 12
