Answer:
- (-11.70, -2.05), (4.70, 5.10)
Step-by-step explanation:
<u>Given equations</u>
<u>Solving the first equation for x:</u>
- (x+5)(x+2)=65
- x^2 + 7x + 10 = 65
- x^2 + 7x - 55 = 0
- x = (-7 ± √(49+4*55))/2
- x = -11.70, x = 4.70
<u>Then solving for y:</u>
- y= 24/(-11.7) = -2.05
- y = 24/4.7 = 5.10
<u>Solution set: </u>
- (-11.70, -2.05), (4.70, 5.10)
Answer:
The total number of <u>fish caught</u> was 42
Step-by-step explanation:
Answer:
12 + 2x
Step-by-step explanation:
<em>simplifying</em><em> </em><em>expression</em><em>:</em>
2(10) + 2(x-4)
2 × 10 = 20
2 × x = 2x
2 × -4 = -8
20 + 2x - 8
20 - 8 = 12
12 + 2x
<em>if you want to simplify it</em><em> </em><em>more</em><em>:</em>
(12/2) + (2x/2)
2(6 + x)
<em>if you want to solve for x:</em>
12 + 2x = 0
(12 - 12) + 2x = (0 - 12)
2x/2 = -12/2
x = -6
