Answer:
y = -1
Step-by-step explanation:
Notice that the line x = 9 is a vertical line, therefore a line perpendicular to it will be a horizontal line of the form y = constant number.
Since we want it to go through the point (9, -1), then we know that that y value needs to be "-1", and the equation of the line will be given by the expression:
y = -1

</span>100%------------> $700 (is the Original tv cost)
X %--------------> $500 (is the Current tv cost)
x=500*100/700----> 71.43%
the percent of decrease=100%-71.43%-----> 28.57%-----> 29%
the answer is
the percent of decrease is 29%
Answer:
Step-by-step explanation:
The angles must be acute and all the measured angles must be different.
<h3>What is a triangle?</h3>
This a shape with 3 sides and angke
If in ΔNOP, OP = 7, PN = 13, and NO = 19, then the measure of the angles must be different as well;
Hence the statement that must be true about the angles is that the angles must be acute and all the measured angles must be different. The given triangle must also be a scalene triangle
