Step-by-step explanation:
y+y = 7
.................
If you would like to solve 7x + 9 = 6x - 5 for x, you can do this using the following steps:
<span>7x + 9 = 6x - 5
</span>7x - 6x = -5 - 9
x = - 14
The correct result would be x = - 14.
Answer: The first one is 90%.
Step-by-step explanation:
Answer:
g(- 4) = - 32
Step-by-step explanation:
substitute x = 4 , g(4) = - 4 into g(x)
4a + b = - 4 → (1)
substitute x = 6 , g(6) = 3 into g(x)
6a + b = 3 → (2)
subtract (1) from (2) term by term to eliminate b
2a + 0 = 3 - (- 4)
2a = 3 + 4 = 7 ( divide both sides by 2 )
a = 3.5
substitute a = 3.5 into (1) and solve for b
4(3.5) + b = - 4
14 + b = - 4 ( subtract 14 from both sides )
b = - 18
Then
g(x) = 3.5x - 18 , so
g(- 4) = 3.5(- 4) - 18 = - 14 - 18 = - 32
Answer:
19.5
Step-by-step explanation:
BY THE SECANT/TANGENT SEGMENT LENGTH THEOREM
= 10 x (28 + 10) = 10 x 38 = 3819.50
x = square root of 380 = <u>19.49358869 (approximately 19.5)</u>

<u><em>
</em></u>
<u><em>If a secant and tangent are drawn from a common exterior point, then the
</em></u>
<u><em>product of the length of the secant with the length of its external
</em></u>
<u><em>segment is equal to the square of the length of the tangent.</em></u>
