F(-3)=(-3)2 - 1 / -3 + 4
f(-3)= -6 -1 / -3 + 4
f(-3)= -7/1
f(-3)=-7
Answer:
The largest side of given triangle is: AB
Step-by-step explanation:
In order to find the largest side, we have to find all the triangles first.
The two angles at point A will sum up to 180° as the angles on the straight line are supplementary.
So,

∠A = 44°
∠C = 71°
The sum of interior angles of a triangle is 180°
Using this:
∠A+∠B+∠C = 180°
44°+∠B+71° = 180°
∠B+115° = 180°
∠B = 180°-115°
∠B = 65°
In a triangle, the side opposite to the largest angle is the largest. In the given triangle, ∠C is the largest so the side AB which is opposite to ∠C is the largest.
Hence,
The largest side of given triangle is: AB

Answer:
a. 
Step-by-step explanation:
The slope-intercept form of equation of a line is given as
. Where,
m = slope
b = y-intercept.
Rewrite the equations,
and
, in the slope-intercept form by making y the subject of the formula. Then, derive our new equation that has the same slope as the first equation, and the same y-intercept as the second equation.


Divide both sides by 5


Rewrite

The slope of
is ⅖.

(subtraction property of equality)
Divide both sides by 4
The y-intercet of
is -6
Therefore, the equation that has the same slope as the first equation and the same y-intercept as the second equation would be:

Plug in the values of m and b
