If we have the equation of a line: y=ax+b
How to find a if with only the x<span>-intercepts (called m)</span> and y-intercepts (called n)
+ First we have y=0 and x=m or 0=a*m+b or b= -a*m
+ Then we have x=0, y=n or n=a*0+b or b=n
And if m≠0 we have a= -n/m
and if m=0 this line has no slope
Answer:
y+2=1/2(x+1)
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(0-(-2))/(3-(-1))
m=(0+2)/(3+1)
m=2/4
m=1/2
y-y1=m(x-x1)
y-(-2)=1/2(x-(-1))
y+2=1/2(x+1)
Answer:
This is four term polynomial.
Step-by-step explanation:
Polynomial comes from poly(meaning “many”) and nomial (in this case meaning “term”). So it says “many terms” A polynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables.
In this expression, we are to determine the polynomials depending on the number of terms present in the expression. The prefixes of the classification suggest the number of terms present.
a^2 - b + c - d^3
This is an example of a four-term polynomial. The first term is a^2, second one is -b, the third one is c, and the fourth one is -d^3.
I am pretty sure D. Cause I did the problem and it seems to make sense
Answer:240 days
Step-by-step explanation: 210 lbs is 3 times more than 70 lbs. There fore it takes 3 times longer to eat. 80 days times 3 is 240 days
