Answer:
y - 4 = 4 (x + 3)
Step-by-step explanation:
Point-slope form is y - y1 = m (x - x1)
y1 is 4, m is 4, and x1 is -3
When you plug them in, you get: y - 4 = 4 (x + 3)
Note: (x - -3) becomes (x + 3)
I hope this helps!!
Answer:
$1.9
Step-by-step explanation:
2 pound bag (when he bought) =.30×2=$0.6
when he sells, price is $2.50.
Profit for each bag= $2.5-$0.6=$1.9
He got a 5% raise, so 28,140 is 105% of what it used to be.
105% means 1.05
(1.05) x (salary before increase) = 28,140
Divide each side by 1.05 :
Salary before increase = 28,140 / 1.05 = <u>26,800</u> .
The rest of the question is nonsense. The salary
before increase IS last year's salary.
