The point-slope form of the equation of a line that passes through points (8, 4) and (0, 2) is y - 4 = 1/4(x- 8). What
Sladkaya [172]

Hi! I'm happy to help!

Point slope form states that y-y_{1}=m(x-x_{1}). m represents your slope (rise/run) and y_{1} and x_{1} represent your first y and x points, and y and x represent your second y and x points. We already have our equation here:

y - 4 = 1/4(x- 8)

Now, let's dive into what slope-intercept form is. Slope intercept form states that y=mx+b. m represents our slope, b represents our y intercept, y represents a y point, and x represents the corresponding x point.

Since we know our m, we can solve for b, by using our other numbers. Let's use our first set of coordinates.

4=1/4(8)+b

4=2+b

2=b

Now our second set to double check:

2=1/4(0)+b

2=0+b

2=b

We know that b must equal 2, so our equation must be y=1/4x+2, which is  option 3.

<u>You should pick option 3.</u>

<u>(y-intercept is where the line hits the y-axis(when x=0). We could've used our second coordinates (0,2), where x equals 0 to know that 2 is the y-intercept (b). This shortcut only works on specific problems though.)</u>

I hope this was helpful, keep learning! :D

f(x)=4x^3-4x+1\\ F(x)=x^4-\frac{x^2}{2}+x\\ \int_{-2}^{2} f(x)=F(2)-F(-2) \implies\\ (2)^4-\frac{2^2}{2}+2)-((-2)^2-\frac{(-2)^2}{2}-2)= \\ 16-2+2-(16-2-2)=16-(16-4)=4

I've done this a million times and I'm still getting 4 instead of 32. Are you sure you posted the coefficients?

X + 3x² – 28x <br><br> Can you guys help me solve this in ax^2+bx+c <br> Thank you thank you
Molodets [167]

Answer:

3x²+(-27x) +0

Step-by-step explanation:

The given expression is :

x + 3x² – 28x

We need to solve this in the form of ax²+bx+c.

we can write the given expression as :

3x²-28x+x = 3x²-27x

= 3x²+(-27x) +0

If we compare the given expression with the general expression, we find that,

a = 3, b = -27 and c = 0

Hence, the required equation is 3x²+(-27x) +0.
