Answer:
x=2.833
Step-by-step explanation:
−4(3/2x−1/2)=−15
-4(3/2x)-4(-1/2)= -15
-2(3x)+2=-15
-6x=-15-2
-6x = -17
x= -17/-6
x=2.833
 
        
             
        
        
        
Y = -3x + 4
In y = mx + b form, the y intercept will be in the b position.
y = mx + b
y = -3x + 4......so ur y intercept is 4.....or (0,4)
just so u know....in y = mx + b form, the slope will be in the m position....so ur slope would be -3

SInce there are six teams and each pair of shoes for each individual player is $630, set up this equation:
630 (total thus far) = 6x (six times the cost of last year)
630/6 = x
This means that last year's cost was $105.
