Given:
five times a number = 5x
decreased by 8 = 5x - 8
is at most 10 = maximum is 10 so less than or equal to 10
more than twice the number = greater than 2x.
2x < 5x - 8 <u><</u> 10
5x - 8 <u><</u> 10
5x - 8 > 2x
****
5x - 8 <u><</u> 10 if x = 3.60 then 2x < 5x-8 <u>< </u>10
+ 8 +8 2(3.6) < 5(3.6) - 8 <u><</u> 10
5x <u><</u> 18 7.2 < 10 <u><</u> 10
÷5 ÷5
x <u><</u> 3.60
5x - 8 > 2x x > 2.67; if x = 3
+8 + 8 2x < 5x - 8 <u>< </u>10
5x > 2x + 8 2(3) < 5(3) - 8 <u>< </u>10
-2x -2x 6 < 7 <u>< </u>10
3x > 8
÷3 ÷3
x > 2.67
Answer:
Step-by-step explanation:
We know from the graph
and
using the given equation we can solve
subtract 1 from both sides so that k is isolated
The answerthe complement of the question is perhaps the functionf(x)= x4 - 5x2to find the value of x-intercepts, just egalize f(x)= x4 - 5x2 to 0, and solve the equation.that is x4 - 5x2 = 0 equivalent to x²(x²-5) = 0, this implies x²-5 = 0 and x²=0,it implies x=0 and x²= 5, which means x = +/- sqrt(5)so the x intercepts are x=0, x = - sqrt(5) and x = +sqrt(5)
finally the answer is 3 x intercepts
