Answer:
Step-by-step explanation:
x + 2 + x + 4 = 34
2x + 6 = 34
2x = 28
x = 14
14 + 2 = 16
14 + 4 = 18

Step-by-step explanation:
Answer:
Part a) The constant of variation is
or 
Part b)
Step-by-step explanation:
Part a) Find the constant of variation.
we know that
The simple interest formula is equal to
In this linear direct variation the constant r represent the constant of proportionality
where
I is the Interest Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
substitute the values and solve for r


Part b) what will the interest be after 3 years
in this part we have
substitute the values
Answer and Step-by-step explanation:
what must be true is that this particular two lines are not a set of PARALLEL lines. When the lines are parallel, the corresponding angles are congruent and the then the pairs of consecutive angles formed are supplementary .
If we are takling about corresponding angles, they will not be congruent if the lines are not parallel
For the given triangle, the cosine of angle A equals
.
Step-by-step explanation:
Step 1; In the given triangle, the opposite side has a length of 9 units, the adjacent side has a length of 3√3 units while the hypotenuse of the triangle measures 6√3 units. To calculate the cosine of angle A we divide the adjacent side by the hypotenuse side.
cos A =
.
Step 2; Length of the adjacent side = 3√3 units.
Length of the hypotenuse side = 6√3 units.
cos A = 3√3 / 6√3
cos A =
.
To check we also have A = 60° and cos 60° =
.
