Rewrite the equation 2y - 4x = 10 in function notation where f(x)= y. f(x)=

Mathematics

Answer:

f(x) = 5 + 2x

Step-by-step explanation:

2y - 4x = 10

<u>      +4x    +4x</u>

2y = 10 + 4x

Now we have a new equation but we have to isolate the variable y.

\frac{2y}{2}  = \frac{10 + 4x}{2}  Then divide to solve for y.

y = 5 + 2x

Since f(x) is the same thing/equal to y we can just replace that.

f(x) = 5 + 2x

Hope that helps and have a great day!

Answer:

Answer:

f(x) = 5 + 2x

y+4x^2-1 is the same as y=-4x^2+1, then replace y with f(x); f(x)=-4x^2+1. After you do that, replace x with 2; f(2)=-4(2)^2+1. 2^2=4, 4 times -4=-16, -16+1=-15. So f(2)=-15.

Express (x-1)^2<br> as a trinomial in standard form.
Andrews [41]

Answer:

x² - 2x + 1

Step-by-step explanation:

We want to express (x - 1)² as a trinomial. In other words, we want to expand this out.

(x - 1)² = (x - 1)(x - 1)

We use FOIL (First, Outer, Inner, Last). The First terms are x and x. Multiply:

x * x = x²

The outer terms are x and -1. Multiply:

x * (-1) = -x

The inner terms are -1 and x; multiply:

(-1) * x = -x

The last terms are -1 and -1; multiply:

(-1) * (-1) = 1

Add all these together:

x² + (-x) + (-x) + 1 = x² - 2x + 1

find the equation of the line passes through the point (-1,2) and making an angle of 45° with the line x-y+1=0​
Vlad1618 [11]

Answer:

Step-by-step explanation:

line given is x-y+1= 0

you can rewrite it in slope intercept y=mx+b where m is the slope, and b is the y-intercept where the line meets the y-axis

x-y+1 =0 subtract x and 1 from both sides of the equation

-y = -x-1 multiply both sides by -1

y = x+1 so the slope of this line is 1 and the y-intercept is 1

If you draw this line you can see that there are actually 2 lines that form 45° angles with y=x+1 and pass through (-1, 2), one is vertical x= -1 and one horizontal y =2
