Hey there! :)
Answer:
y = 10/9x + 8/3
Step-by-step explanation:
A line that is perpendicular to y = -9/10x - 10 has a slope that is the negative reciprocal. Therefore:
-9/10 --> 10/9. This is the slope of line q.
Use the formula y = mx + b where:
m = slope
x = x coordinate of point
y = y coordinate of point.
-4 = 10/9(-6) + b
-4 = -60/9 + b
Create a common denominator:
-36/9 = -60/9 + b
24/9 = b
Simplify:
b = 8/3.
Rewrite the equation:
y = 10/9x + 8/3
Answer:
-17 degrees
Step-by-step explanation:
Given that:
Initial temperature = 2 degrees
Final temperature = -15 degrees
To Determine:
The change in temperature.
Solution:
First of all, let us have a look at the method for calculating the change in any quantity.
Let the initial quantity =
Let the final quantity =
Change in quantity = Final quantity - Initial quantity =
Here, we are given the quantity as temperature.
where degrees and
degrees
Therefore, the change in temperature = -15 - 2 = <em>degrees</em>
Answer:
mi res puesta puede ser 8 creo no estoy segura
Answer:
total number of tickets sold is 387
students tickets were two times that of adult which is 2x
adult is x
2x + x =387
3x=387
x=387/3
x=129
recall that adult is x
therefore adult is 129
to confirm the answer, remember that the student tickets sold is twice that of the adult. if adult is 129 then student ticket is 129 x2 which is 258 plus the number of adult ticket sold which is 129 the sum of the 258 and 129 is 387
