Answer:
Below
Step-by-step explanation:
(2x/x+3) + (x+3/x-5)
Transform: 2x(x-5) + (x+3)^2 / (x+3)(x-5)
Remove brackets and expand : 2x^2 - 10x + x^2 + 6x + 9 / x^2 - 5x + 3x - 15
Collect like terms : 3x^2 - 4x + 9 / x^2 - 2x - 15
Final answer: 3x^2 - 4x + 9 / x^2 - 2x - 15
-9p - 5m = 60
-9p - 5m + 5m = 5m + 60
-9p = 5m + 60
-9 -9
p = ⁻⁵/₉m - 6²/₃
You have to add 5m on each side in order to find the value of p. then, you have to divide it by -9 in order to find the value of p.
First, find the slope (m) =
=
=
= 
Now plug in ONE of the points and the slope into the point-slope equation:
y - y₁ = m(x - x₁); where (x₁, y₁) is the chosen point.
y - 5 =
(x - 1) (I used (1,5) as the chosen point)
3(y - 5) = x - 1
3y - 15 = x - 1
3y -14 = x
-14 = x - 3y → x - 3y = -14
Answer: x - 3y = -14
Answer: 7 - - 12, -3 - 9, 15 - - 80
Step-by-step explanation:
Q24) It’s wrong because 7 - - 12 = 7 + 12 because two minus signs make a plus sign, 7 + 12 = 19
Q25) The answer is -3 - 9 because going deeper means negative
Q26) The answers would be 15 - - 80, this equals 90
Answer:
x = 7.99 cm
Step-by-step explanation:
By applying cosine rule in the given triangle,
AC² = AB² + BC² - 2(AB)(AC)cosC
Substitute the measures of the sides and the angle in this formula,
x² = 6² + 10² - 2(6)(10)cos(53°)
x² = 36 + 100 - 72.217
x² = 63.782
x = √(63.782)
x = 7.99 cm
