Answer:
<em>X=</em><em>-</em><em>1</em><em>8</em><em>/</em><em>7</em>
Step-by-step explanation:
-6x+18+2x=-18x-18
-4x+18= -18x-18
-4x+18x=-18-18
14x=-36
x=-36/14
x=-18/7

Answer:
The range of the function is {-1 , -11 , 7}
Step-by-step explanation:
- The range is the resulting values of y we get after substituting all
the possible values of x
- The domain of the function is the values of x
- The range of the function is the values of y corresponding to the
values of x ⇒ [y = f(x)]
∵ f(x) = -2x² + 7
∵ The domain D = {2 , -3 , 0}
- We need to find the values of f(x) corresponding to x = 2 , x = -3
and x = 0
- Substitute the values of x in f(x)
∵ x = 2
∴ f(2) = - 2(2)² + 7
∴ f(2) = -2(4) + 7
∴ f(2) = -8 + 7
∴ f(2) = -1
∵ x = -3
∴ f(-3) = - 2(-3)² + 7
∴ f(-3) = -2(9) + 7
∴ f(-3) = -18 + 7
∴ f(-3) = -11
∵ x = 0
∴ f(0) = - 2(0)² + 7
∴ f(0) = -2(0) + 7
∴ f(0) = 0 + 7
∴ f(0) = 7
The range of the function is {-1 , -11 , 7}
Answer:
D divide both the numerator and denominator by cos(x)cos(y)

Answer:
<h2>Step-by-step explanation:</h2>
Put the values
a = 3 as well as b = 4
- (a)² + (b)² = c²
- (3)² + (4)² = c²
- 9 + 16 = c²
- 25 = c²
- 5 = c
<h2>Proof:</h2>
(3)² + (4)² = 5²
9 + 16 = 25
25 = 25
<h3>
Hence verified, that a² + b² = c²</h3>
