Answer:
Quadrants I and IV
Step-by-step explanation:
When we graph y^2 = x - 4, we see that it is on the x axis, and goes up into Quadrant I, and down into Quadrant IV
SOLUTION:
Let whole number = x
x + 2x^2 = 21
2x^2 + x - 21 = 0
2x^2 + 7x - 6x - 21 = 0
x ( 2x + 7 ) - 3 ( 2x + 7 ) = 0
( 2x + 7 ) ( x - 3 ) = 0
2x + 7 = 0
2x = - 7
x = - 7 / 2
OR
x - 3 = 0
x = 3
ANSWER:
Therefore, as 3 is a whole number while - 7 / 2 isn't a whole number, the whole number must be 3.
Hope this helps! :)
Have a lovely day! <3
Given situation: The first
2 digit of the 2 different numbers is in the hundred millions place.
Then both numbers also have the same digit.
Now, which is greater. Of the two numbers?
The answer would be the same. The same because they both have the place
value of millions place and they also share the same digits.
Thus, I conclude the both different numbers have the same value.
And since they have the same value, they are equal
Answer:
c = 1/32
Step-by-step explanation:
32-x-x-x-x-x-x-x
32/4 = 8
so product 1/4 is the rule
32/4^5= 2^5/2^10
2^-5=1/32
Step-by-step explanation:
the change in cost of 145-135.50 = 9.50 for an increase of students from 25 to 30. The ratio of change of cost to change of students = 9.50/5 = 1.9 and becomes the slope coefficient "m" in the formula y= mx + b. y = the total cost, mx becomes the variable cost and b becomes the fixed cost. To find b, use the data point given where the total cost = $135.50 when the students = 25, or 135.50 = 1.9*25 +b. Solving for b yields $ 88. Note that the other data point is where the total cost is $145 for students = 30. Using the new total cost equation shows that 30*1.9+88= 145
