Hello :
calculate the slope :
<span>2x + 5y = 10
5y = -2x +10
y = (-2/5)x +2
the slope is (-2/5)... (</span><span> parallel so : same slope )
an equation is : y - (-5) = (-2/5)(x-1)</span>
Answer:
x = 30
Step-by-step explanation:
here 50 is hypotenuse as it is opposite of 90 degree.
x and x + 10 are the two other smaller sides of a right angled triangle respectively.
using pythagoras theorem,
a^2 + b^2 = c^2
x^2 + (x + 10)^2 = 50^2
x^2 + x^2 + 20x + 100 = 2500
2x^2 + 20x + 100 = 2500
2x^2 + 20x + 100 - 2500 = 0
2x^2 + 20x - 2400 = 0
2(x^2 + 10x - 1200) = 0
x^2 + 10x - 1200 = 0
x^2 + (40 - 30) - 1200 = 0
x^2 + 40x - 30x - 1200 = 0
x(x + 40) - 30(x + 40x) = 0
(x + 40)(x - 30) = 0
either x + 40 = 0 OR x - 30 = 0
x = 0 - 40
x = -40
x - 30 = 0
x = 30
x = -40,30
since the length and distance is not measured in negative ur answer will be 30

thank u very much . At first i was wrong and giannathecookie i m really sorry
To do this addition mentally, you should do like this:
31 requires 9 more to become 40 and since we have a nine in our question, we would first do 31 + 9 = 40. Now you would finish it off with the remaining number which is six. 40 + 6 = 46.
<u>Steps</u>:
31 + 9 = 40
40 + 6 =46
Therefore, your answer would 46.
