Answer:
x intercept is (3.75, 0) and y intercept is (0, 2.5)
Step-by-step explanation:
4x + 6y - 15 = 0
x int = (3.75, 0)
0*6 = 0
4x - 15 = 0
0 + 15 = 4x = 15
15/4 = 4x
x = 3 3/4 or 3.75
y int = (0, 2.5)
0*4 = 0
6y - 15 = 0
15 = 6y
15/6 = y
y = 2.5
Answer:
7
Step-by-step explanation:
-2 x 6 = -12
-6/1 ÷ -3/1 = 2
-12 - 2 = -14
-14 ÷ -2 = 7
a) After 4 years the profit will change from negative to positive.
b)after 4 years the profit will be lowest.
Because the equation is a quadratic equation so, it will be increasing.
c) after 4 years the profit will be 5.
<u>Step-by-step explanation:</u>
a) After 1 year = 2(1) -6(1) -3
= 2-9
= -7
It's negative
After 2 years = 2(4) -6(2) -3
= 8-12-3
= -7
It's negative
After 3 years = 2(9) -6(3) -3
= 18 - 18 -3
= -3
It's negative
After 4 years = 2(16) -6(4) -3
= 32 -24-3
= 5
It's positive
After 4 years the profit will change from negative to positive
b) after 4 years the profit will be lowest.
Because the equation is a quadratic equation so, it will be increasing.
c) profit = 2(16) - 6(4) -3
= 32 -24 - 3
= 5
after 4 years the profit will be 5
<em>Answer: 62.4 computers or 62 </em>
<em />
<em>Step-by-step explanation:</em>
<em>Use this equation </em>
<em>48(n)</em>
<em>n will be 0.30 since the sales must increase by 30%</em>
<em>48(0.30)</em>
<em>14.4</em>
<em>Now add 48 and 14</em>
<em>48+14.4</em>
<em>62.4 or round it down to 62</em>
