Answer:
-5<x<10
Step-by-step explanation: in these types of questions you have to leave x alone which means you have to do the following:
-6<x-1<9
when we throw -1 to the left side the solution would be like this -6+1=5
and when we throw it to the right side the solution would be 9+1=10
which means;
-5<x<10
Answer:
Step-by-step explanation:
x^2 - 6x - 27
(x - 9)(x+3)
Answer:
The correct option is B.
Step-by-step explanation:
We know, from the definition of |x|,
|-8x| = - 8x, when - 8x ≥ 0 i.e. x ≤ 0 ......... (1)
and |-8x| = 8x, when - 8x < 0 i.e. x > 0 .......... (2)
Now, for x ≤ 0 {i.e. condition (1)}
- 8x ≤ 8, ⇒ x ≥ - 1 ......... (3)
Again, for x > 0 { i.e. condition (2)}
8x ≤ 8, ⇒ x ≤ 1 .......... (4)
So, combining conditions (3) and (4) we get -1 ≤ x ≤ 1.
So, the correct option is B. (Answer)
Here's one example.
1) Catering Costs
"celebrations" offers catering services. They charge 30 dollars initially, and 1.5 dollars per person.
a) C representing cost and P representing people. The equation of this relation is C = 1.5p + 30
b) C P
32 1
33.5 2
35 3
36.5 4
(The table can be used to make points)
(p,C)
c) You can rewrite this in standard form.
C = 1.5t + 30
0 = 1.5t - C + 30
-30 = 1.5t - C
30 = -1.5t + C
Another example:
2) Transportation.
A car is driving from City A to City B at a constant speed of 80km/h The distance away from both cities is 240km.
a) In which D represents distance in km and T represents time in hours, an equation that can represent the distance away from City B is D = -80t + 240
b) D t
160 1
80 2
0 3
(These can be used to make points)
c) You can rewrite in standard form.
D = -80t + 240
0 = -80t - D + 240
-240 = -80t - D
240 = 80t + D
