Answer:
4
Step-by-step explanation:
Because there are 10 pices and 4 of them are greater than 6
Answer:
$4.40
Step-by-step explanation:
you do 24=5x-2 so first you do 24-2 and u get 22 so then divide that by 5 since they each pay 5. then u end up with 4 dollars and 40 cents
The equation that models the balance y after x is y = -145x + 1400
<h3>How to find the equation?</h3>
given that
Zachary uses a payment plan to buy a PC for $1,400. His balance was $820 four months after he made the computer purchase. His amount was $240 eight months after he made the computer purchase.
Assume it has to do with developing an equation that represents this loan as a function of time. Use the loan amount as Y and the time as X.
Now Put that in the standard format:
Y = mX + b
according to the question
at x = 0 then y = 1400
at x = 4 then y = 820
at x = 8 then y = 240
now find the slope
points are (4,820) & (8,240)
slope = -145
now the equation is y = -145x + b
Let x = 4 & y = 820
then
820 = -145(4) + b
820 = 580 + b
b = 820 + 580
b = 1400
finally the equation is
y = -145x + 1400

Step-by-step explanation:
4x^2 - 8x >= 0
Factor left side
4x(x - 2) >=0
Then case I) 4x <=0 and x - 2 <= 0
so x <= 0 and x <= 2
So x <= 0
Answer:
the first question is: B Reflection over the X axis.
