Answer:
2(3(5) - 4(2) = 14
Step-by-step explanation:
I used a calculator called MathPapa!
Answer: Confusing.
If it's f(x) is 2 times 2 minus 8, it's a horizontal line at y-4.
If it's f(x) is 2x 2-8
It's handy to use a graphing calculator.
Step-by-step explanation:
Be sure to clarify what the equation means
Thanks to Desmos for the graphs.
As you can see, the numbers could represent a lot of different things-- especially when 'x' can be a variable -- or confused with the multiplication sign.
Answer:
well, we do not have the options here, but we can find the equation of the graph, so the equations that are different from that are the answer to this question:
in the graph, we can see that it goes through the points:
(0,1) and (2,0)
Remember that the slope of a line that goes through the points (x1, y1) and (x2, y2) is:
s = (y2 - y1)/(x2- x1)
then the slope for our line is:
s = (0 - 1)/(2 -0) = -1/2
Then our line is:
y = -(1/2)*x + b.
b is the y-intercept, and we know that when x = 0 y = 1, then:
1 = -(1/2)*0 + b
1 = b
then the equation is:
y = -(1/2)*x + 1
Answer:
the one on the left (the first one)
