-32
Step-by-step explanation:
Answer:
Where's the x?
I am assuming that the problem must be
-3 + 42 > 3x
if that is true, then
<u>x < 13</u>.
As this statement is, -3 + 42 > 3 is a true statement because -3 + 42 = 39, and
39 > 3 [39 is always greater than 3]

Answer:
Step-by-step explanation:
The shape of the graph is called a PARABOLA.
The domain of the function is the set of all real numbers, and the range of the function is the set of all real numbers greater than or equal to (-4).
[Parabola is opening upwards and the lowest point is it's vertex (2, -4). Therefore, range of the function will be y ≥ -4]
When x = -1,
Value of the function 'f' will be,
f(x) = 5
[Graph passes through (-1, 5)]
Answer:
Step-by-step explanation:
<em>The lines form legs of a right triangle, so the distance between the cars is the hypotenuse</em>
<u>The lines at t hours are:</u>
<u>So the distance d is:</u>
- d = √(70t)²+(45t)² = √4900t²+2025t² = √6925t² = 83.22t
- d = 83.22t
Answer:
a 13 students
b 9 groups
Step-by-step explanation:
I will assume we want equal amounts of children from each grade
6th grade:
27 = 3*9 = 3*3*3
7th grade
36 = 4*9 = 2*2*3*3
8th grade
54 = 6*9 = 2*3*3*3
The terms that appear in each of 6th, 7th and 8th are 3*3
That is the greatest common factor
3*3 = 9
We can make 9 groups, Factor out the 9 and what is left is the number from each grade that is in each group
6th grade:
27 = 3*9 There will be 3 6th graders in one group
7th grade
36 = 4*9 There will be 4 7th graders in one group
8th grade
54 = 6*9 = There will be 6 8th graders on one group
In one group we have 3+4+6 = 13 people
There will be 9 groups of 13 children
