Answer:
Expression 3
Step-by-step explanation:
State that a coefficient is a multiplicative factor, is a number in front of a variable, in some term of a polynomial.
The coefficients of the expression 3, for example, are 3, 7 and 24.
1 nickels =$0.05
1 dime= $0.1
let the number of nickels be x and that of dimes be y.
total number of coins is given by:
x+y=42
hence:
y=42-x.......i
total amount of cash will be:
0.05x+0.1y=3.30.........ii
substituting i in ii we get:
0.05x+0.1(42-x)=3.30
0.05x+4.2-0.1x=3.3
-0.05x=-0.9
x=-0.9/(-0.05)
x=18
hence the the number nickels is x=18, the number of dimes will be y=42-x=42-18=24
Answer:
you need to find the vertex, y-intercept, x-intercept, etc in order to create the equation.
Step-by-step explanation:
standard form for quadratic equations should look like this:
f(x)= ax^2+bx+c
(The graph is really blurry, try posting just the graph so I can see it closer if you still need help setting up the equation.)
