Answer: 2.4 degrees F
Step-by-step explanation:
okay. the point has an x and y value. place them into the equation.
1=m(1)+b
m=slope, and theequation tells you that slope is 7.
1=7(1)+b
now you need to figure out what b is.
1=7(1)+b
^
1= 7 +b
-7 -7
---------------
-6=B
b is 6. now place it into the equation, replacing the x and y values back.
y=7x-6.
write 7 and 6 in the boxes (the negative for the six has already been provided)
<h3>Answer:</h3>
3. R(x) = 25,500 -720x -12x²
<h3>Explanation:</h3>
Starting from 340 tickets, the number of tickets increases by 4 for each unit change in x. Hence, tickets sold will be (340 +4x).
Starting from $75, price per ticket decreases by $3 for each unit change in x. Hence ticket price is (75 -3x).
Revenue from ticket sales is the product of the number of tickets and the price at which they are sold:
... R(x) = (340 +4x)·(75 -3x)
... R(x) = 25,500 -720x -12x² . . . . . matches the 3rd choice
Answer: THIRD OPTION.
Step-by-step explanation:
For this exercise it is important to remember that, by definition, two triangles are congruent when all their corresponding sides and their corresponding angles are congruent.
Therefore, the size and shape of two congruent triangles are equal.
In this case you know that the triangles shown in the given picture are congruent.
So, based on the explained before, you know that the measure of every corresponding angle of both triangles is the same.
Then, you can conclude that unknown angle "x" has the same measure that the corresponding angle of the other triangle:
.
Therefore, you get that the value of "x" is:

This matches with the third option.
Most calculators would translate what you have written as
22
÷
1254
=
And the answer coming up would be 0.01754
======================
If you meant it the other way
1254
÷
22
=
Then the answer is 57.
You have to know for sure which way you want to put this into your calculator
