Answer:
The solution is (4, 1).
Step-by-step explanation:
Answer:
$132.00
Step-by-step explanation:
15 cases at $66; 66 divided by 15= $4.40 a case
20 cases at $88; 88 divided by 20=$4.40 a case
35 cases at $154.00; 154 divided by 35=$4.40 a case
therefore 30 cases x $4.40 per case = $132.00
The answer is 50 miles per hour
Rearrange it so that it starts with x=
I am a bit rusty, but I get x= y-b/m
Answer:

Step-by-step explanation:
(i)
+ = 1 ( multiply through by 6 to clear the fractions )
2x + 3y = 6 ( subtract 2x from both sides )
3y = - 2x + 6 ( divide through by 3 )
y = - x + 2
(ii)
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope ( gradient ) and c the y- intercept )
y = - x + 2 ← is in slope- intercept form ( that is part (i)
with gradient m = -
