If p(4) = 16 then
n*4² + 8 = 16
16n + 8 = 16
16n = 16 - 8
16n = 8
n = 8/16 = 0.5

If n = 0.5 then
p(-3) = 0.5*(-3)² + 8
p(-3) = 0.5 * 9 + 8
p(-3) = 4.5 + 8
p(-3) = 12.5

What is the slope of the line whose equation is 4x – 6y = 12?
zhannawk [14.2K]
4x - 6y = 12...in y = mx + b form, the slope will be in the m position. So lets turn this equation into y = mx + b form.

4x - 6y = 12....subtract 4x from both sides
-6y = -4x + 12...now divide both sides by -6
y = (-4/-6)x + 12/-6
y = 2/3x - 2...y = mx + b.....slope(m) = 2/3 <==

Find the area of an obtuse-angled triangle with a base of 4 cm and a height 7 cm.​
SOVA2 [1]

Answer:

14 cm²

Step-by-step explanation:

Obtuse angle: more than 90° and less than 180°

The formula for the area of an obtuse triangle is the same as that for any triangle:  

  • area of a triangle = 1/2 x base x height

Therefore, given:

  • base = 4 cm
  • height = 7 cm

⇒ area = 1/2 x 4 x 7 = 14 cm²

4/25+1/5 in simplest form
Evgen [1.6K]
It would be 9/25. First you find the common denominator which is 25 so then you convert 1/5 to 5/25 so now you have 4/25+5/25 which you would get 9/25 and since 9 can only be divided be 3 and 25 can't your answer would be 9/25.

Nataly_w [17]

Answer:

Rogue's operating income is $770000

Step-by-step explanation:

Given data

Sales​ = $3,000,000

Cost of Goods Sold​ = $1,500,000

Depreciation Expense​ = $170,000

Administrative Expenses​ = $150,000

Interest Expense​ = $30,000

Marketing Expenses​ = $80,000

Taxes​ = $300,000

to find out

operating income

solution

we find income by this formula that is given below

income = Sale - Cost of Goods Sold - Depreciation Expense - Administrative Expenses - Interest Expense -  Marketing Expenses - Taxes

so put now all these value to get the income      

income = 3,000,000 - 1,500,000 - 170,000 - 150,000 - 30,000 - 80,000 - 300,000

hence            

so  Rogue's operating income is $770000
