Answer:
Step-by-step explanation:
hello :
y=6x...(*)
y = 5x + 7...(**)
by (*) put the value of y in(**) :
6x=5x+7
6x-5x=7
x=7 but y=6x so : y=42
the system solution is (7,42)
Answer:
5+c
Step-by-step explanation:
Simplify
-(-5-c) is -1(-5-c)
Keep in mind that if there is a negative sign in front of a bracket it's always -1
Simplify Brackets you get
5+c
Answer:
Triangle 1 -
, hypotenuse = 16

Triangle 2 -
, adjacent leg = 18

Triangle 3 -
, opposite leg = 12

Step-by-step explanation:
Each triangle is solved by means of trigonometric relations:
Triangle 1 -
, hypotenuse = 16



Triangle 2 -
, adjacent leg = 18



Triangle 3 -
, opposite leg = 12



Depends on the question but you generally must use a variety of operations to isolate the variable by itself on one side of the equation
Answer:
4x + 15
Step-by-step explanation:
A = 14x + 5[6 - (2x + 3)]
= 14x + 5[6 - 2x - 3]
= 14x + 30 - 10x - 15
= (14x - 10x ) + (30 - 15)
= 4x + 15
Hope this helps!
