Hi,

$f(x)=\log(x)$ FALSE

$f(x)=\log(x-4)+1$ TRUE

→ $f(x)=\log(x-2)$

$f(x)=\log(x+2)$ FALSE

$f(x)=2log(x)$ TRUE

F(x) = log(x) . . . FALSE

f(x) = log(x -4) +1 . . . TRUE

f(x) = log(x -2)

f(x) = log(x +2) . . . FALSE

f(x) = 2log(x) . . . FALSE . . . . . the graph looks more like 3log(x)

DOES ANYONE KNOW THE ANSWERS TO THESE PROBLEM, PLZ HELP!

Virty [35]

Answer:

Q.1.

Sum of angles of a triangle = 180°

∠A + ∠B + ∠c = 180

(3x - 9) + (4x + 15) + 90 = 180

3x - 9 + 4x + 15 + 90 = 180

7x + 96 = 180

7x = 84

x = 12

∠A = 3x - 9 = 3(12) - 9 = 36 - 9 = 27°

∠B = 4x + 15 = 4(12) + 15 = 48 + 15 = 63°

∠A = 27°

∠B = 63°

Q.2.

$using \ pythagoras \ theorem \\x^2 = 7^2 + (7\sqrt{3} )^{2} = 49 + 49(3) = 196\\x = \sqrt{196} = 14$

$sin y = \frac{opposite}{hypotenuse} = \frac{7\sqrt{3} }{14} = \frac{\sqrt{3} }{2} \\\\y = sin^{-1} (\frac{\sqrt{3} }{2} ) = 60$

x = 14

y = 60°

Solve the system of linear equations by graphing, round the solution to the nearest tenth.

algol [13]

For this case we have the following system of equations:
$y = -0.25x + 4.7

y = 4.9x-1.64$
When solving the problem graphically we must take into account the following:
1) The solution of the system of equations is given by the intersection of both functions.
2) The solution is an ordered pair of the form (x, y)
For this case we observe that the solution is given by:
$(x, y) = (1.23, 4.39)
$
Note: see attached image.
Answer:
The approximate solution to the system is (1.23, 4.39)
