Answer: -1
Step-by-step explanation:
In order to find the slope, you should remember the formula (Y1-Y2)/(X1-X2) the order of the x and ys do not really matter, but the they should be the same for the top and bottom. In this situation, you can do (4-6) which represent your Y1 and Y2 and then divide by (1 minus -1) which are your xs, this simplifies to -2/2 or simply, a slope of -1
Answer:
x = - 
, x = 
Step-by-step explanation:
Given
x² - x - 
= 0 ( add to both sides )
x² - x =
Solve using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2( - )x + 
= +
(x - )² = 1 ( take the square root of both sides )
x - = ± 1 ( add to both sides )
x = ± 1
Thus
x = - 1 = -
x = + 1 =
Answer:
where are the choices
Step-by-step explanation:
Answer:
Q#1.total number of T-shirts for total cost to be equal=10
Q#2.For the total cost to be the same for both companies, the volleyball team would need to purchase 10 T-shirts from each company
Q#3.total of $105 for each company.
Step-by-step explanation:
Q#1
two functions are given
y=10.5x
y=7.5x+30
where y represents cost and x represents number of shirts
we have to find number of shirts to be purchased from each company keeping cost equal
hence we will write
10.5x=7.5x+30
10.5x-7.5x=30
3x=30
x=30/3
x=10
Number of shirts to be equal cost price is 10
Q#2
two functions are given
y=10.5x
y=7.5x+30
where y represents cost and x represents number of shirts
we have to find number of shirts to be purchased from each company keeping cost equal
hence we will write
10.5x=7.5x+30
10.5x-7.5x=30
3x=30
x=30/3
Number of shirts =x=10
Q#3
total cost=y=?
for y=10.5x
put x=10
y=10.5*10
cost=y=105
and for other function
for y=7.5x+30
put x=10
y=7.5(10)+30
y=75+30=105
