Answer:
See below
Step-by-step explanation:
Given∠A ≅ ∠B and CD⊥ABTo prove CD bisects ∠ACBSolutionAs CD⊥AB, ∠BDC = ∠ADC = 90°
∠BDC ≅ ∠ADC
∠BCD = 180 - (∠BDC + ∠DBC)and
∠ACD = 180 - (∠ADC + ∠DAC)We can substitute ∠ADC with ∠BDC and ∠DAC with ∠DBC
Then we get same equation for ∠BCD and ∠ACD
Therefore ∠BCD = ∠ACD = 1/2∠ACB
It proves that CD bisects ∠ACB

If f(x) = 5x - 6, which of these is the inverse of f(x)?
O A. f'(x) = 5 +6
O B. :'(x)= -6
C. F'(x) = *+6
+ LO
X-6
O D. 8'(X) = *
Answer:
A
Step-by-step explanation:
Because subtraction and addition are alike just how multiplication and division are.
The inverse of f(x) is (x+6)/5, the correct option is A
What is inverse of a function?Suppose that the given function is
[tex]f:X\rightarrow Y[/tex]
Then, if function 'f' is one-to-one and onto function (a needed condition for inverses to exist), then, the inverse of the considered function is
[tex]f^{-1}: Y \rightarrow X[/tex]
such that:
[tex]\forall \: x \in X : f(x) \in Y, \exists \: y \in Y : f^{-1}(y) \in X[/tex]
It simply means, inverse of 'f' is undo operator, that takes back the effect of 'f'
Given;
f(x) = 5x - 6
f^-1 (x ) = x+6/5
Let, y = f(x) and rearrange making x the subject;
y = 5x - 6 ( add 6 to both sides )
y + 6 = 5x ( divide both sides by 5 )
x = (y+6)/5
Change y back into terms of x
x = (x+6)/5
Therefore, the answer in inverse will be (x+6)/5

A box in the shape of a rectangular prism, with dimensions 12 inches by 18 inches by 12 inches, can hold exactly 12 cubes measuring 6 inches on each side.
If the length and width of the base are doubled, how many cubes could the new box hold?
18
24
48
96
Answer: 48 cubes in the new box
Step-by-step explanation:
Doubling the length and the width is 2×2, so 4 times the original capacity.
4×12 = 48
It is not necessary to compute the volume. The dimensions could be anything. It's the number of cubes that count.
Answer:
C, 48

Answer:
See below
Step-by-step explanation:
GivenFunction f(x) = xTransformation ways1. Reflection by a factor of (-3) and vertical shift down -12 units
f(x) = x → (-3) ⇒ h(x) = -3x → (-12) ⇒ g(x) = -3x - 122. Vertical shift up by 4 units and reflection by a factor of (-3)
f(x) = x → (+4) ⇒ h(x) = x + 4 → (-3) ⇒ g(x) = -3x - 12Enter decimal numbers in the boxes to identify the point in Quadrant III which is 3 units away from point A.
Answer:
(-0.5, -0.5)
Step-by-step explanation:
Let the coordinates of the point P in quadrant 3 are (x, y).
If a point A is 3 units apart, coordinates of point P will be [(x - 3), y].
From the figure attached,
Coordinates of the point A are (2.5, -0.5).
x coordinate of point P → (2.5 - 3) = -0.5
y coordinate of the point P → (-0.5) = -0.5
Therefore, point P which is 3 units apart from A will be (-0.5, -0.5)

A bag contains 12 red marbles the ratio of red marbles to blue marbles is 3:4 find the number of blue marbles in the bag
Answer:
16
Step-by-step explanation:
If the ratio is 3 red marbles to 4 blue marbles we can solve this using the following:
[tex]\frac{12}{b} = \frac{3}{4}[/tex]
[tex]12 * 4 = 3b\\48 = 3b\\\frac{48}{3} = b\\b = 16[/tex]
So we have 16 blue marbles.
Based on the ratio of red to blue marbles, the number of blue marbles in the bag is 16 marbles.
The bag has red marbles to blue marbles in a ratio of 3:4.
If there are 12 red marbles, the number of blue marbles can be found by direct proportion:
3 : 4
12 : x
Cross-multiply:
3x = 48
x = 48/3
x = 16 blue marbles
In conclusion, there are 16 blue marbles in the bag.

Three watches and five lamps cost $176 in all. Five watches and three lamps cost $208 in all. What is the cost of one lamp?
$200/5 lamps= $40 per lamp
Final answer: $40
Using the elimination principle, the cost of one lamp is $16
Let :
watches = a Lamps = b3a + 5b = 176 - - - - (1)
5a + 3b = 208 - - - (2)
Multiply (1) by 5 and (2) by 3
15a + 25b = 880 - - - - (3)
15a + 9b = 624 - - - - - (4)
Subtract (3) and (4)
16b = 256
b = (256 ÷ 16)
b = $16
Therefore, the cost of one lamp is $16
