Answer:
solution:
x = pounds of cashews = 20
y = pounds of peanuts = 70
Step-by-step explanation:
x = pounds of cashews
y = pounds of peanuts
---
4.75x + 2.50y = 3.00*90
x + y = 90
---
put the system of linear equations into standard form
---
4.75x + 2.50y = 270
x + y = 90
Answer:
the answer is y 2-=x+5
Step-by-step explanation:

I am assuming ur looking for the sale price....
there are 2 ways to do this...
42 - 0.20(42) = 42 - 8.40 = 33.60 <== sale price
or
if it was 20% off, then u paid 80%...
0.80(42) = 33.60 <== sale price
I think it’s the 1st one because it’s close too what it is when I work it out
Answer:

Step-by-step explanation:
we know that
The linear equation in slope intercept form is equal to

where
m is the slope
b is the y-intercept
<em>Find the slope</em>
The formula to calculate the slope between two points is equal to

take the points
(0,2.5) and (100,97.5)
substitute in the formula



Find the y-intercept b
we have


substitute i the linear equation 

solve for b

Note It was not necessary to calculate the value of b because the value is given in the table
Remember that the y-intercept is the value of y when the value of x is equal to zero (the y-intercept is the point (0,2.5))
The linear equation is
