IM GIVING 30 POINTS Rewrite this equation in slope-intercept form:
4y + 3x = 20
What is the slope?
a. 3/4
b. -3
c. 3
d. -3/4
e. None of these

its "a" ezy

The slope-intercept form is

y

=

m

x

+

b

, where

m

is the slope and

b

is the y-intercept.

y

answer: the first graph

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
