Answer:
<h2>132.25π m²</h2>
Step-by-step explanation:
The circumference of a circle is 23π
On the other hand, The circumference of a circle = 2×π×r ; where r is the radius.
then
by equating the last two expressions we get: 23π = 2πr then r = 23/2
then
the area = π × r² = (23/2)²×π = (132.25)×π
Answer:
3/4
Step-by-step explanation:
Let's use two points to figure out the slope.
For this, I will use
(4,3) and (8,6)
To get the slope we do subtraction with y of one over x of one minus y of two over x of two
So
3/4 - 6/8 We get -3/-4 negatives cancel and the slope is 3/4
Answer:
y=-2x-4
Step-by-step explanation:
1) In this equation, -4 is the y-intercept (which is the point in the graph when x is 0 and y is something.)
2) Then, you have to check if the graph also has a y-intercept of -4 (it does)
3) Find out what the slope of the graph is. In this case, it is -2
4) If the equation also has a slope of -2 and y-intercept of -4, then it represents the graph.
Hope this helps :)

Step-by-step explanation:
<u>Step 1: Define</u>
4x - 12 ≤ 16 + 8x
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 4x on both sides: -12 ≤ 16 + 4x
- Subtract 16 on both sides: -28 ≤ 4x
- Divide 4 on both sides: -7 ≤ x
- Rewrite: x ≥ -7
Here we see that any value <em>x</em> greater than or equal to -7 would work as a solution to the inequality.
∴ our answer is -7.
