Gradient= -3/2 Equation: Y=mx+c Y=2 , X=8
So you substitute the numbers in
2=(-3/2) x 2 + c (then you backtrack to solve for c which is the y intercept)
2=-3+c
5=c So the equation should be Y=-3/2x+5
Answer:
It is a function Jonny!
Step-by-step explanation:
Hello! I would say to Jonny:
Jonny! A function is a relation between two sets, in which every element of the first set (domain) is assigned only one element of the second set (codomain).
If you have serveral elements of the first set with the same corresponding element of the second set it is correct to call that relation a function.
However, if you have an element of the first set for which your relation can relate to more than one element of the second set, then Jonny, that is not a function.
In the present case, every student ID number can only be realted to a number of the set {9, 10, 11, 12}, a student cannot have more than one current grade level. Therefore, that relation is in fact a function
Answer:
yes, y=2x-3 is linear
2x - y = 3 Standard Form
Step-by-step explanation:
since both the 'x' and 'y' variables have one as their exponents then this represents a linear equation
standard form: Ax + By = C
y = 2x - 3
subtract 2x from each side to get:
-2x + y = -3
divide each term by -1 to get (this is done so the leading coefficient is not negative)
2x - y = 3 Standard Form
The radius is 11. I did 7599 divied by 3.14 =2,420. 2,420 divied by 20 and got 121. then i squared that to get 11
Answer:
Step-by-step explanation:
Multiply 3 times 4x which gives you 12. Multiply 3 times 2 which gives you 6. Your final answer is 12x+6
