If f(x) = -2x + 2, f(5) can be found by substituting in the value 5 for x in the equation:
f(5) = - 2(5) + 2
Our first step in simplifying this expression is to perform the multiplication as outlined by the order of operations (PEMDAS).
f(5) = -10 + 2
Finally, we must get our final answer by adding together the remaining terms.
f(5) = -8

Step 1: Put a decimal point at the end of the number: 2445000000.<span>
Step 2: Move the decimal point 9 spaces to the left: </span>2.445000000
Number: 2.445000000 aka 2.445<span>
Exponent: 9
Answer: 2.445 x 109</span>
A) We can first start with the how: our equation is 2x+y=3. First, subtract 2x from each side. We get y=-2x+3. Our Y variable is isolated.
B) Now we can describe which points our equation goes through. One of them is obvious in our form, and that is (0,3) or our y-intercept. Another 2 would be branching off that line, such as (1,1) or (-1,5)
C) To make our system inconsistent, we can easily make another equation, with same slope, but the y-intercept has to be different. Our equation can be y=-2x+2, y=-2x+4, or even y=-2x+3.00000001.
Hope this helps you.
Answer:
$4.50 for French Roast
$7.60 for Columbian
Step-by-step explanation:
tried substitution and elimination method but got different answers to I graphed these equations and found the point of intersection
5/3x + 25/8y = 31.25
29/12x + 9/16y = 15.15
point of intersection (4.5, 7.6)
