2.45cm=1 in
times both sides by 63
160.02cm=63 in
about 160cm
Looking at the number 2800, ask yourself, what 2 factors can ibreak this number into.
One possibility is 28 and 100-- since 28*100 = 2800
so now you have 28 and 100, are any of these prime?
the answer is no
28 can be factored into 4 and 7 and 100 can be factored into 10 and 10
so now you have
4,7,10,10
which ones of these are prime?
well, 7 is a prime number but 4,10, and 10 are not. Since they are all even, then they can be divided by 2
4 = 2*2
10=2*5
so factoring those numbers give you
2,2,7,2,5,2,5
putting them in order,
2,2,2,2,5,5,7
now, the question is, are these numbers all prime.
if yes, then you're done with prime factorization, if not, then you just continue the process
Answer:
It has a negative slope = -2
Step-by-step explanation:
Let y be the price and x be the quantity purchased . Then putting the value of x in the equation we can find the price= y
where y = −2x+8
x 0 1 2 3 4 5 6 7
y 8 6 4 2 0 -2 -4 -6
So we can plot the demand curve which has a negative slope.
We see from the values above that the slope is negative having a value equal to -2. This means that for every increase in the number of quantities there is a decrease in the price.
In a linear equation like y=2x+7 the slope represents
Answer:
This is the answer
Step-by-step explanation:
Solving 3x2-9x-5 = 0 by the Quadratic Formula .
According to the Quadratic Formula, x , the solution for Ax2+Bx+C = 0 , where A, B and C are numbers, often called coefficients, is given by :
- B ± √ B2-4AC
x = ————————
2A
In our case, A = 3
B = -9
C = -5
Accordingly, B2 - 4AC =
81 - (-60) =
141
Applying the quadratic formula :
9 ± √ 141
x = —————
6
√ 141 , rounded to 4 decimal digits, is 11.8743
So now we are looking at:
x = ( 9 ± 11.874 ) / 6
Two real solutions:
x =(9+√141)/6=3/2+1/6√ 141 = 3.479
or:
x =(9-√141)/6=3/2-1/6√ 141 = -0.479
Two solutions were found :
x =(9-√141)/6=3/2-1/6√ 141 = -0.479
x =(9+√141)/6=3/2+1/6√ 141 = 3.479
