Answer:
gradient = -  , y- intercept =
 , y- intercept = 
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
3x + 4y = 5 ( subtract 3x from both sides )
4y = - 3x + 5 ( divide terms by 4 )
y = -  x +
 x +  ← in slope- intercept form
 ← in slope- intercept form
with slope m = -  and y- intercept c =
 and y- intercept c = 
 
        
             
        
        
        
Answer:
40 quarts.
Step-by-step explanation:
Let x =quarts of the 50% solution
so, according to the question 
the typical mixture equivalent equation will be like this 

so the answer will be 40 quarts of 50% solution should be added.
 
        
                    
             
        
        
        
Answer:
A = 0.25*j + 1
Step-by-step explanation:
The question presented here is an application of linear models. The $1 amount is fixed and does not depend on any factor such as the cups of orange juice sold.
Furthermore, we are informed that we earn $0.25 for every cup of orange juice sold. This means that we shall earn 0.25 j by selling  j cups of orange juice.
The variable total amount, A will thus depend on the fixed amount of $1 and the variable income 0.25 j.
The equation in two variables that will represent the total amount A (in dollars) you have after selling j cups of orange juice will thus be;
A = 0.25*j + 1

Answer: Second Option

Step-by-step explanation:
We are evaluating aarco lengths
The formula for the arc length is:

We want to know what is the arc length for a radius of r = 8
Then we substitute r = 8 in the equation and solve


The correct answer is the second option
