<h3><u>Answer:</u></h3>
- x = 66°
- y = 48°
<u>Since this is an isosceles triangle, the base angles must be the same. Hence, </u><u>x = 66°.</u>
<u>Since we have found x, we can find y by using the 180-angle method.</u>
- => y + 66 + 66 = 180
- => y + 132 = 180
- => y = 180 - 132
- => y = 48°
Therefore, the answers are:
- x = 66°
- y = 48°

Answer:
f(x)= 4x+9
F(x)=1/x
Step-by-step explanation:
An odd function accomplish the following condition:
f(-x) = -f(x) (1)
By checking (1) on each of the next functions, we have:
f(-x) = (-x)^3 - (-x)^2 -f(x) = - (x^3- x^2)
f(-x) = (-x)^5 -3(-x)^3 + 2(-x) -f(x) = -x^5 +3x^3 +2x
f(-x)= -4x +9 = -f(x)
F(-x) = -1/x =-F(x)
Answer:
see explanation
Step-by-step explanation:
(a)
y = - bx
substitute y = 6 , x = 1 into the equation
6 = a - b → (1)
substitute y = 0 , x = 2 into the equation
0 = - 2b ( multiply through by 2 to clear the fraction )
0 = a - 4b → (2)
multiply (1) by - 4
- 24 = - 4a + 4b → (3)
add (2) and (3) term by term to eliminate b
- 24 = - 3a + 0
- 24 = - 3a ( divide both sides by - 3 )
8 = a
substitute a = 8 into (1) and solve for b
6 = 8 - b ( subtract 8 from both sides )
- 2 = - b ( multiply both sides by - 1 )
2 = b
Then a = 8 and b = 2
(b)
when x = 4
y = - 2(2) = 2 - 4 = - 2
