When rounding a number, the digit of the number can be increased up to 1, but the digit won't be decreased. So, it is possible to round a five digit number into six digit number. But to increase the number digit, the number should be rounded up. To be rounded up, a number should have value 5 or more.
(0,-1) and (2,0)= ( 0+1)/(2-0)= 1/2
the answer is 1/2
Slope of that line would be
(0-6)/(3-0) = (-6)/3 = -2
then slope intercept form is
y = mx + b
where m = slope and b is the y intercept
so now we have y = -2x + b
and the y intercept is when x = 0
so b = 6 from that point (0,6)
so we have the equation
y = -2x + 6
which is option C
it's good to write it out
length = 5 + width
area = 150
width = x
length = 5 + x
area = length * width
so
(5 + x) (x) = 150
5x + x^2 = 150
x^2 + 5x - 150 = 0
following you have to guess what 2 numbers when multiplied male 150 and when added make 5
and they are 15 and 10
(x +15) (x-10)
x = -15
x = 10
so the dimensions are
length = 15
and
width = 10
Answer:
y= 4+x
Step-by-step explanation:
she has 4 gallons already in the tank
she puts in x more
therefore the total amount in the tank is 4+x
