Answer: B), C), and E)
Explanation for B:
This is one of the correct statements because to simplify the fraction into decimal form you would need to divide the numerator by the denominator, which in this case; 35 is the numerator and 40 is the denominator. Therefore divide 35 by 40 is a correct statement.
Explanation for C:
This is another correct statement because when you actually divide the number 35 from 40 into a decimal, you end up with the value 0.875.
Explanation for E:
Another correct statement. In decimal form, the fraction 35/40 terminates, meaning it does not go on forever, and it also does not repeat forever. When a decimal does not terminate or repeat, it is considered a rational number. Since the decimal 0.875 does neither, it is also considered a rational number.

Answer:
D
Step-by-step explanation:
4. However, you can do this in a Calculator.
Move constant to other side
add 1
4c^2-8c=1
divide by 4 to make leading coeficient 1
c^2-2c=1/4
take 1/2 of linear coeficient and square it
-2/2=-1, (-1)^2=1
add that to both sides
c^2-2c+1=1/4+1
factor perfect squaer and add
(c-1)^2=5/4
square root both sides
c-1=+/-(√5)/2
add 1
c=1+/-(√5)/2
c=2.12 or -0.12
Answer:
-3/4 is the slope.
Step-by-step explanation:
Use this formula to find slope.
y2-y1/x2-x1
PLUG IN
-2 -1/2- (-2) = -3/4
The slope is -3/4
