Answer:
the answer is -30
Step-by-step explanation:
-10 is being multiplied to this minus '-'(-3).
so we get +10 because -×- is +.
then, +10 is being multiplied to -3 in which we get -30
Answer:
Ans:
i) y-int (0 , 2) and x-int (-2/3 , 0)
ii) y = 3x + 2
Step-by-step explanation:
<em>we know:</em>
m = 3 & point (0,2)
<em>i</em>
y-int is (0,2) because where x is 0 it intersects the y-axis
<em>ii</em>
<em>from this we can sub it into the point slope formula which is:</em>
y - y1 = m (x - x1) (y1 and x1 being the values from a point lying on the line)
y - 2 = 3 (x - 0)
y - 2 = 3x
<u>y = 3x + </u><u>2</u> < this is the equation
if you also need to find the x-int then:
to find x-int make y = 0 and solve for x
y = 3x + 2 3x = - 2
0 = 3x + 2 x = -2/3
therefore x-int is (-2/3,0)
Angle to the top of the building or base of the tower = 36 degrees
Angle to the top of the radio tower on the building = 46 degrees
Distance from the base at which the surveyor is standing = 67 meters
Let us assume the distance of the base of the tower from the surveyor = x1
Let us assume the distance of the top of the tower from the surveyor = x2
Then
tan(36) = x1/67
x1 = 67 tan(36)
and
tan(46) - x2/67
x2 = 67 tan(46)
Now
x2 - x1 = 67 tan(46) - 67 tan(36)
= 20.702
= 20.7 m
From the above deduction, it can be concluded that the correct option among all the options that are given in the question is the second option or option "b".
7 + 3x = 22
3x = 22 - 7
3x = 15
x = 15/3
x = 5
so if x = 5, then 2x = 2(5) = 10
