Answer

Step-by-step explanation:

For exercises one- three, your slopes are m=, so thinking of the slope intercept form y=mx+b. Plug in the (x,y) coordinates into the equation

for example question 1:

1=4(3)+b

or for question 2:

7=-3(2)+b

For exercises 4 and 5, simply just find the y intercept by seeing where on the why axis the line is one a certain point. and to find the slope do the equation

y2-y1/x2-x1

for example number 4:

-1-2/4-2 and your slope would equal - 3/2

so your equation would be

y= -3/2+5

hope this helps ;)

−px+r=−8x − 2, x=?<br> now i have to do this problem, and i dont know how, help?
Taya2010 [7]

-px + r = - 8x - 2

-px + r + 8x +2 = 0

-px +8x = -r -2

x(8-p) = -r -2

x= \frac{8-p}{-r-2} =

\frac{8-p}{-r-2}

Solve the equation for a? z=mab. a)a=z+mb b)a=z-mb c)a= mb/z d)a=z/mb
Bingel [31]

Answer:

a = z/mb

Step-by-step explanation:

Given:

\displaystyle \large{z=mab}

To solve for a, divide both sides by the variables mb to isolate a-term.

\displaystyle \large{\dfrac{z}{mb}=\dfrac{mab}{mb}}

Simplify the expression and we finally have solved for a-term.

\displaystyle \large{\dfrac{z}{mb}=a}\\\\\displaystyle \large{a=\dfrac{z}{mb}}

Therefore, the answer to this question is a = z/mb.

Please let me know if you have any questions regarding my answer or explanation!

How can you rewrite the expression (8-5i)^2 in the form a+bi?
otez555 [7]
(a-b)^2 = a^2-2ab+b^2

(8-5i)^2 = 8^2-2(8)(5i)+(5i)^2

= 64-80i+25i^2

i^2=-1

So

= 64-80i+25(-1)

=64-25-80i

= <em><u>39 - 80i</u></em>

which is your answer :)
