Answer:
y=-3x-1
Step-by-step explanation:
The mistake that was made was in the denominator of the work. The second 2 should be the -1. This is what you should get:
Hope that clear things up.
The values for x and y are respectively given as
This is further explained below.
<h3>What is the values for
x and y ?</h3>
Generally, the equation for secent is mathematically given as
Therefore
80 = 130-x
x = 50
b) To Solve for y Now we find a measure of arc CD
ArcCD = 360-130-50
ArcCD = 180
In conclusion,(1/2) of the arc measure is equal to the angle that is on and inside a circle.
y = 180/2
y= 90

Answer: x doesn't equal four x would have to equal -5 because it cant before because it would be a zero and there would be no solution

A factor is any number that can be divided into another number evenly. When factoring, we look for common factors within a math expression. Factoring is normally used when finding common factors. The beauty of finding common factor is that it allows us to apply the distributive property usually applies multiplication to an existing mathematical expression such as an addition statement. This means that a number that is outside the parenthesis of an addition problem can be multiplied by each of the numbers inside the parenthesis. The opposite case is; a common factor can be factored out and written outside the parenthesis.
Answer:
x = 25
Step-by-step explanation:
Since the triangles are congruent then corresponding angles are congruent.
That is ∠ D and ∠ B are corresponding angles and congruent, thus
4x - 20 = 2x + 30 ( subtract 2x from both sides )
2x - 20 = 30 ( add 20 to both sides )
2x = 50 ( divide both sides by 2 )
x = 25
