Answer:
The value of x is 4 and the value of y is 9
Step-by-step explanation:
In the attached pictures we can see that two lines are intersecting with each other and four angles are form. The angles opposite to each other are also called vertical angles.
The opposite pairs of angles are:
(10x-4)° and 6(x+2)°
(18y-18)° and 16y°
When two lines intersect each other, the vertical angles formed are congruent(Can also be called equal in measurement)
So,
Subtracting 6x from both sides
Adding 4 on both sides
Dividing both sides by 4
AND
Adding 18 on both sides
Subtracting 16y from both sides
Dividing both sides by 2
Hence,
The value of x is 4 and the value of y is 9
Given :
When price is $2 dollars he sells 2400 units .
When price is $8 dollars he sells 600 units .
To Find :
If x represents the price of trucks and y the number of items sold, write an equation for the demand curve.
Solution :
Two points are given :
Now , slope is given by :
Now , the equation of line containing these two points and slope -300 is :
Therefore , equation for the demand curve is .
Hence , this is the required solution .
Answer:
D.
Step-by-step explanation:
It's impossible to know if either A or B is true based on the information given to us in the diagram, so it cannot be A or B. C is false because all three of the angles in a triangle add up to 180°, and the equation in C only includes two angles. So the answer is D because it is the only statement we know to absolutely be true. Both angles three and four share one line (a line is 180°), so their sum must be 180°.
Answer:
17x +7y
Step-by-step explanation:
8x + 10y + 9x - 3y
Combine like terms
8x+ 9x + 10y - 3y
17x +7y
8x+9x are like terms and 10y -3y are like terms
