"x" would have to equal 1/2. You'd divide by 2 on both sides then simplify.
y=mx+b is the equation of a line;
m=slope , b= y-intercept
m=4 ; so we have : y=4x+b
We are give a set of points which it passes through, we can simply plug them in:
-2 = 4(3)+b (3 is the x and -2 is the y)
We get -2 = 12 +b .... -14=b
our final equation is : y=4x-14
Answer:
(3rd listed choice) Paula's notes are incorrect. Step 4a should be "If the result does not define y as a function of x, then f does not have an inverse," and step 4b should be "If the result defines y as a function of x, then f has an inverse."
Step-by-step explanation:
If f(y) = x can be solved for a relation for y that is a function, then f(x) has an inverse. It will be the function defined by y.
A) f(x)=0.2x
B)f(12)=0.2(12)=2.4 dollars
Answer:
Step-by-step explanation:
so i cant actually see the picture on my school chromebook, but if only one x matches up to one y, then yes. multiple x's can go to a single y
