Answer:

11/12

Step-by-step explanation:

find the lcm of 12 and 3 which is 12.

find a common factor in 12 and 3 and use those factors to multiply with their numerators.

7 * 1 and 1*4 =11

while the denominator or the lcm is 12

thus 11/12

Answer:

4

Step-by-step explanation:

3y=12  divide both sides by 3

y=4

Answer:

y = 4

Step-by-step explanation:

12 = 3(4)

12 = 12

Answer:

Step-by-step explanation:

SYSTEM:

log base root3 of (x-y) = 2 .... 1

log base 4 of x - log base x of y =7/6...2

From equation 1:

x-y = (√3)²

x - y = 3 ..... 3

From equation 2:

log base 4 of x - log base x of y =7/6

-log base x of 4 - log base x of y = 7/6

log base x of 4^-1 - log base x of y = 7/6

log base x of (1/4) - log base x of y = 7/6

According to law of logarithm

Log base x {1/4 ÷ y} = 7/6

x^7/6 = 1/4y .... 2

From 1, y = x-3

x^7/6 =1/4(x-3)

x^7/6 = 1/(4x-12)

x^7/6(4x-12) = 1

Answer: 234,253.50

Work: I did 22 to the power of 4 first and I got 234256. I subtracted 2 which is 234254, and than took 1/2. So, the answer is 234253.50.

Answer:

Assuming the question is asking for angle B, it measures 23°

Step-by-step explanation:

If angle A = 67°, and angle A and angle B are complementary, then you know they add up to 90°.

angle A + angle B = 90°

67° + Angle B = 90°

Angle B = 23°

Answer:

68

Answer:

We conclude that the value of the constant of proportionality.

Step-by-step explanation:

We know that if 'y' varies directly with 'x', we use the equation

y ∝ x

y = kx

where 'k' is called the constant of proportionality.

Given the equation

y = 14x

comparing with the equation

y = kx

Thus,

k = 14

Therefore, we conclude that the value of the constant of proportionality.

Step-by-step explanation:

Translating two units down means we need to subtract two units from the y-coordinate. i.e

(x, y) → (x, y-2)

We are given that the original point is (1, 2), and we have to find the image of (2, 4) obtained by translating 2 units down followed by a rotation of 180 counterclockwise.

                                                FOR (1, 2)

Given

First translation: Translating two units down

(x, y) → (x, y-2)

P(1, 2) → P'(1, 2-2) → P'(1, 0)

Second transformation: Rotation of 180 counterclockwise.

Rotation of 180 counterclockwise will make both 'x' and 'y' coordinates negative. i.e

(x, y) → (-x, -y)

Thus, after second transformation

P'(1, 0) → (-1, 0)

Thus, the image of (1, 2) obtained by translating 2 units down followed by a rotation of 180 counterclockwise will be: (-1, 0)

                                                    FOR (2, 4)

Given

First translation: Translating two units down

(x, y) → (x, y-2)

P(2, 4) → P'(2, 4-2) → P'(2, 2)

Second transformation: Rotation of 180 counterclockwise.

Rotation of 180 counterclockwise will make both 'x' and 'y' coordinates negative. i.e

(x, y) → (-x, -y)

Thus, after the second transformation

P'(2, 2) → (-2, -2)

Thus, the image of (2, 4) obtained by translating 2 units down followed by a rotation of 180 counterclockwise will be: (-2, -2)

Answer:

g(x) = - 3  ;   x = 3

p(x) = - 5  ;   x = -3, -9

f(x) = 5  ;  x = 3, 5  

Answer:

24 = (9 * 6) - (15 + 15)

Step-by-step explanation:

Equation = (9 * 6) - (15 + 15)

Follow PEMDAS which in this case multiply 9 x 6

= 54 - (15+15)

Now you need to add the numbers that are in the parenthesis

= 54 - 30

= 24

Answer:

5,6,7

Step-by-step explanation:

consetive integers are 1 apart

they are

x,x+1,x+2

3 times the first added to the last is 22

3x+x+2=22

combine like terms

4x+2=22

minus 2 both sides

4x=20

divide both sides by 4

x=5
