8(2x) - 8(14) +13 = 4x -27
16x - 112 +13 = 4x -27
then combine like terms
16x - 99 = 4x -27
subtract 4x from both sides
12x - 99 = -27
add 99 to both sides
12x = 72
divide both sides 12 to isolate the x
x = 72/12 = 6
Find the sine and cosine of the given angle
120°
Answer:
By using the value of cosine function relations, we can easily find the value of sin 120 degrees. Using the trigonometry formula, sin (90 + a) = cos a, we can find the sin 120 value. We know that the value of cos 30 degrees is √3/2. Therefore, sin 120° = √3/2

Determine whether the graph represents a function . If it does represent a function , give its domain and range.
#18,20,24,30
PlEASE GUYS HELP ME OUT!!!!
Answer:
A function is a relationship that maps elements from a set (the domain) into elements from another set (the range)
Such that each element in the domain can be mapped into only one element from the range.
Let's see graphs 18, 20,24 and 30.
Remember that the axis that represents the domain is the horizontal one (usually represented with x), and the vertical axis represents the range (usually represented with y)
18) Here we can see that the point x = 1 his mapped into two different values of y.
we have the pair (1, 2) and the pair (1, -3)
And something similar happens for x = 2.
Then we can conclude that this is not a function.
20) Here we have a linear relationship.
Linear relationships are almost always functions, the only case when these are not functions is when the linear equation is something like x = a.
Linear equations can be written as:
y = a*x + b
So x can be any value, and thus y also can be any value.
Then the domain is the set of all real numbers, and the range is the set of all real numbers.
24) Here we have a quadratic function whose arms go down.
This is a function, now let's see the domain and range.
Quadratic functions are written as:
y = a*x^2 + b*x + c
There is no value of x can cause some problem in this equation, then this function works for all values of x, then the domain is the set of all real numbers.
Now, let's look at the graph.
We can see that the function goes up, reaches a maximum, and then goes down again.
Then the range will be the set of all the values smaller than the maximum we can see in the graph, this is:
y ∈ (-∞, 15]
or simply:
y ≤ 15.
30) Here again, we can see that for x = 0 there are two different values of y.
the same happens for x = -1, x = -2, and a lot of other values.
Then this is not a function, because it is mapping values of the domain into different values of the range.

A ray can intersect a circle in __________.
1. a line segment
2. a line
3. a ray
4. a point
Answer:
a line segment.
Step-by-step explanation:
a line segment
A ray can intersect a circle at points on the circumference. Option D is correct.
The circle is the locus of a point whose distance from a fixed point is constant i.e center (h, k). The equation of the circle is given by
(x - h)² + (y - k)² = r²
where h, k is the coordinate of the center of the circle on the coordinate plane and r is the radius of the circle.
Here,
A ray can intersect a circle at a maximum of two points,
The line which intersects the circle at two points is called the secant to the circle, and the line that intersects the circle at one point is called the tangent two the circle.
Thus, a ray can intersect a circle at points on the circumference. Option D is correct.

LMNP is a rectangle. Find the length of each diagonal. LN=x and MP=2x-9
Answer:
LN = MP = 9 units
Step-by-step explanation:
In rectangle LMNP, LN and MP are diagonals .
Measures of the diagonals of a rectangle are equal.
Therefore,
MP = LN
2x - 9 = x
2x - x = 9
x = 9
LN=x = 9 units
MP=2x-9 = 2*9 - 9 = 18 - 9 = 9 units

Answer:
[tex]\frac{9}{14}[/tex] = 0.642857143
Step-by-step explanation:
[tex]\frac{1}{7}+\frac{1}{2}[/tex]
Least common multiple of 7 and 2 is 14. Convert [tex]\frac{1}{7} and \frac{1}{2}[/tex] to fractions with denominator 14.
[tex]\frac{2}{14} + \frac{7}{14}[/tex]
Since [tex]\frac{2}{14} + \frac{7}{14}[/tex] have the same denominator, add them by adding their numerators.
[tex]\frac{2+7}{14}[/tex]
Add 2 and 7 to get 9.
[tex]\frac{9}{14}[/tex]

Aaron is twice as old as Ryan.In 3 years,the sum of their ages will be 30 years.Find Aaron′s present age
Answer:
If we take Ryan's age as 'x' then we have Aaron's age as '2x'
Now, we have the sum of their ages after 3 years as 30.
So according to question, we can prepare an equation which is
2x+3+x+3 = 30
= 3x+6 = 30
= 3x = 30-6
= 3x = 24
= x = 24÷3
= x = 8
Thus, Ryan' is 8 years old now.
Now we need to find Aaron's age, and this can be done easily as we have already made an expression fore Aarons age, i.e., '2x'
So 2x= 2×8
= 16.
So we have Aaron's age-16,
Ryan's age-8
