2y+8x=1 in slope intercept form

1 answer:

6 0

The slope-intercept form is y = mx + b.
Following that kind of form becomes
2y = -8x + 1
y =(-8x + 1)/2
y = -4x + 1/2

Hope this helps ✌️☺️✌️

The width is basically the diameter, and all you have to do is divide by 2 to get the radius.B is the name for base. I think the formula for a triangle is 1/2 bh. and for the circle c=pieD i hope that helped!

Math riddle! Correct answer gets brainliest! Answer with what x and y are equal to.

RSB [31]

Answer:

$\displaystyle [9, 4\frac{1}{2}]$

Step-by-step explanation:

I figure these exercises out by numeric association. I see a 3, so I know right away that there might be a 9 somewhere. So, you start by plugging 3 in for $\displaystyle x,$ THEN plug $\displaystyle 1\frac{1}{2}$ in for $\displaystyle y$ sinse there are twise the quantity of $\displaystyle y$ than there are of $\displaystyle x.$ Now, doing so will give you $\displaystyle 24 ≠ 18.$ This tells you to try another pattern, so go with plugging $\displaystyle 4\frac{1}{2}$ in for $\displaystyle y$ and $\displaystyle 9$ in for $\displaystyle x$ . Doing so gives you what you are looking -- $\displaystyle 36 = 36.$ Therefore, the association wourked perfectly. ☑

I am joyous to assist you at any time.

What is f(-1)? Show your work. Question 4 options:

adelina 88 [10]

F(-1) = 3

How did I figure this out?

f(-1) is substituted for f(x) so you must look at -1 on the x axis.

Once you've located -1 on the x-axis, locate what it equals to answer the question.

The answer should be the y-axis number that corresponds to -1 which is 3.

Can someone please help me with my algebra fraction homework pages 8,9 and 10. Thank you!

Answer:

Step-by-step explanation:

#8 the answer is A

using special products, fact the denominator of both fractions

q^2+5q+6 is the same as (q+2)(q+3)

q^2+3q+2 is the same as (q+2)(q+1)

no you have to find the lease common denominator of the two fractions

multiply the first fraction by (q+1)/(q+1)

multiply the second fraction by (q+3)/(q+3)

you will get (q^2+2q+3)/(q+1)(q+2)(q+3) after you combine like terms and stuff like that.

#9 the answer is C

using special products factor the numerator of the first fraction, and the denominator of the second fraction

r^2+7r+10 is the same as (r+2)(r+5)

r^2-5r-50 is the same as (r-10)(r+5)

then factor the numerator if the second fraction

3r-30 is the same as 3(r-10)

is the second fraction there is (r-10) in the numerator and denominator, simplify that.

then simplify the 3, and the (r+5)

you will be left with r+2 from the first fraction

#10 the answer is A

when you divide same base exponents, you subtract their powers

x^0/x^2 = x^-2 and

y^-3/y^-1=y^=2

so you are left with x^-2*y^-2 but that is not an option

we also know that negative exponents is the same thing as the reciprocal with the exponent in the denominator

x^-1 = 1/x

x^-2*y^-2 = 1/x^2*y^2
