Answer:
x y
2 76
4 64
7 47
9 34
13 10
Step-by-step explanation:
If we have an initial value of 88, that would be the y intercept
The rate of change -6 which is the slope
y = -6x+88
Let x =2
y = -6(2) +88 =
-12+88
= 76
Let y = 64
64 = -6x +88
Subtract 88 from each side
64-88 = -6x
-24= -6x
Divide by -6
-24/-6 =x x=4
Let y = 46
46 = -6x +88
Subtract 88 from each side
46-88 = -6x
-42= -6x
Divide by -6
-42/-6 =x x=7
Let x =9
y = -6(9) +88 =
-54+88
= 34
Let y = 10
10 = -6x +88
Subtract 88 from each side
10-88 = -6x
-78= -6x
Divide by -6
-78/-6 =x x=13
Answer:
B.
Step-by-step explanation:
Step 1: Cross-multiply
x² + 2x = 4x²
Step 2: Isolate <em>x</em>'s
2x = 3x²
0 = 3x² - 2x
Step 3: Factor
x(3x - 2) = 0
Step 4: Find roots
x = 0, x = 2/3
Step 5: Double check answers.
When you do so, you should see that only x = 0 works. And we have our answer!
Answer:
<h2>3(2+4)÷(10-1) = 2</h2><h2 />
Step-by-step explanation:
3×(2+4)÷(10-1) = 3×(6)÷(9) = 18÷9 = 2
This is another one for the "impossible geometry question" file.
Answering the last question first, the sum of exterior angles of any convex polygon is 360°.
This fact tells us that the sum of interior angles is 10*180° - 360° = 1440°. Without additional information, we do not know the measure of each interior or exterior angle.
If we assume all angles are equal, then
Each interior = 1440°/10 = 144°
Each exterior = 180° -144° = 36°
The rational expression is the following
By applying the sandwich rule:
we have
which gives
then, the answer is option 2.
