Answer:
Angle B = 131 degrees
Step-by-step explanation:
We know that since there's an angle labeled 139 degrees and a straight line is 180 degrees in total, the other angle is equal to 180 - 139 = 41 degrees.
Since all triangles have 3 angles that add up to 180 degrees and we know that theres a right angle, a 41 degree angle, then angle A must equal to 180 - 41 - 90 = 49 degrees.
We know that vertical angles are congruent, therefore angle C is also equal to 49 degrees.
Angle B and angle A form a straight line, which we have defined as 180 degrees.
180 - 49 = 131 degrees.
Angle B = 131 degrees
Answer:
f(4) = -15
Step-by-step explanation:
Since we have an average rate of change, we can deduce that a line, with a gradient of -6 joins the points on the function, f, when the parameter is 1 and when it is 4, i.e. the line passes through the point (1, 3) and has a gradient of -6;
From this, we know that for every value of x we increase the, value y will decrease by 6;
So if we increase 1 by 3, to get to 4, the y value must decrease by 18 (3×6);
Written mathematically, it would look like:
f(4) = 3 + (4 - 1)(-6)
= 3 - 18
= -15
(4, -15)

Step-by-step explanation:
The variables are listed top down in the variable vector in the same order as the coefficients are listed left-to-right in the equations. Each of the equations needs to have the variables listed in the same order.
