Let the three integers be x - 1 x and x + 1
(x - 1)(x + 1) = 6x + 6
x^2 - 1 = 6x + 6
x^2 - 6x - 7 = 0
(x - 7)(x + 1) = 0
x - 7 = 0
x = 7
x + 1 = 0
x = - 1
the solutions are (7,0) and (-1,0)
4+.95=4.95
4.95*3= 14.85
The student paid $14.85 for the three cans.
Answer:
Step-by-step explanation:
is an exponential equation where A is the beginning amount and B is the rate that the population grows or dies.
So we start with 1000 bacteria, they are giving us A.
The bacteria population is decreasing because they are dying 5% each hour.
So that is after the first hour we have 1000-.05(1000) or 1000(1)-1000(.05)=1000(1-.05)=1000(.95).
We will keep multiplying by .95 per hour. 0.95 is the repeated factor.
That is the function is .
If you let h=0 which means 0 hours has happened, you will see the bacteria is 1000 as desired. 1000(.95)^0=1000(1)=1000.
False
(x,y)
so if it lies on the y axis, then x=0
it has to be (0,y) for it to lie on y axis
since we have (6,6), it does not lie on any axis
false
Answer:
rectangles are similar figures, thus if scaled copies of each other then the ratios of corresponding sides must be equal
compare ratios of lengths and widths
rectangles A and B
k = = ← ratio of lengths
k = = ← ratio of widths
scale factors are equivalent, hence rectangle A is a scaled copy of B
rectangles C and B
k = = ← ratio of lengths
k = = ← ratio of width
scale factors (k ) are not equal, hence C is not a scaled copy of B
rectangles A and C
k = = ← ratio of lengths
k = ← ratio of widths
the scale factors are not equal hence A is not a scaled copy of C
