The total of their age be in three years time is 40 years.
As per the given data:
The total of the age of Ann, Bob and Chri is 31 years.
Let the present age of Ann is 'x' years.
Then the age of Ann after 3 years will be x+3
Let the present age of Bob is 'y' years.
Then the age of Bob after 3 years will be y+3
Let the present age of Chri is 'z' years.
Then the age of Chri after 3 years will be z+3.
The total of the age of Ann, Bob and Chri is 31 years.
x + y + z = 31.....(i)
The total of the age of Ann, Bob and Chri after 3 years is ( x + 3 + y + 3 + z + 3 ) years.
= ( x + 3 + y + 3 + z + 3 )
= ( x + y + z + 9 )
From equation (i)..... ( x + y + z = 31 )
= 31 + 9
= 40 years
Therefore the answer is 40 years.

The ground pool for a hot air balloon can see the balloon in the sky at an angle of elevation of 11°. The pilot radios the crew that the balloon is 950 feet above the ground. What is the horizontal distance from the balloon to the ground crew.
Answer:
4,886.83feet
Step-by-step explanation:
The question will result in a right triangle with
Opposite = distance of the balloon above the ground = 950feet
Angle of elevation = 11 degrees
Required
Horizontal distance h (adjacent)
Using SOH CAH TOA identity
Tan theta =opp/adj
Tan 11 = 950/h
h = 950/tan 11
h = 950/0.1944
h = 4,886.83feet
Hence the horizontal distance from the balloon to the ground crew is 4,886.83feet

Use the points form of a line to write the equation of a line thag that has a slope of 2 and passing through the points (-4,3) write the equation in slope intercept form
If the equation is passing trough the origin, it will be passing trough the point (0,0). We now for our problem that the equations is also passing trough the point (-4,3). So, our line is passing trough the points (0,0) and (-4,3). To write the equation in slope-intercept form, first, we need to find its slope . To do that we are going to use the slope formula: .
From our two points we can infer that , , , . Lets replace those values in the slope formula:
Now that we have our slope, we can use the slope-intercept formula:
We can conclude that the equation of the line passing trough the points (0,0) and (-4,3) is .

Find k so that x + 2 is a factor of x ^ 3 - k * x ^ 2 + 2x + 7k. (If anyone could help me out with this that would be amazing!!)
Answer:
k = 4
Step-by-step explanation:
If x + 2 is a factor of the polynomial;
By the factor theorem, if we set x + 2 = 0, then make x the subject of the formula; if we substitute the value into the polynomial, the result we should have after calculating should be zero
So, we have it that;
x + 2 = 0
x = -2
Substitute into the polynomial and equate to zero
(-2)^3 - k (-2)^2 + 2(-2) + 7k = 0
-8 -4k -4 + 7k = 0
-12 -4k + 7k = 0
-12 + 3k = 0
-3k = -12
k = -12/-3
k = 4

Select all that apply. Given the points (3, 2) and (6, 4), which of the following are true about the line passing through these points? The point (-6, 9) is also on the line. The line has a slope of . The line has a slope of . The line represents a direct variation function.
Answer:
The point (-6, 9) is also on the line. False
The line has a slope of . (this statment is incomplete!)
The line has a slope of . (this statment is incomplete!)
The line represents a direct variation function. True ( y=2/3x )
Answer:
Slope of the line through the points (3,2), (6,4) is (4-2)/(6-3) = 2/3
"The line has a slope of 3/2". False, the slope is 2/3 not 3/2
"The line represents a direct variation function". True, as y = (2/3)x (which is a direct variation)
"The line has a slope of 2/3". True (as just proved by number one)
"The point (-6,9) is also on the line". Does y = (2/3) x 9 = (2/3) (-6) = -4?
No sir it does not so that's False.
