Given A || B

Mathematics
1 answer:
NNADVOKAT [17]4 years ago
6 0

Answer:

x = 24

Angle 1 = 101°

Angle 2 = 79°

Angle 3 = 101°

Angle 4 = 101°

Angle 5 = 79°

Angle 6 = 79°

Angle 7 = 89°

Angle 8 = 89°

angle 2 and 3 are supplementary

that means the sum of these angles are both equal 180°

Step-by-step explanation:

4x + 5 + 3x + 7 = 180

4x + 3x = 180 - 5 - 7

7x = 168

x = 168/7

x = 24

4*24 + 5 = 101

3*24 + 7 = 79

5*24 - 29 = 91

3*24 + 19 = 91

Y is equal to the additive inverse of 4x. Use this information to find the value of the expression 17x + 3y in terms of x.
nevsk [136]

Answer:

<h3>5x</h3>

Step-by-step explanation:

The additive inverse of a function is that value added that will sum it up to zero

If y is the  additive inverse of 4x, then y = -4x

Given the expression 17x+3y

Substitute y = -4x into the expression to have;

17x + 3(-4x)

17x -12x

5x

Hence the value of the expression in terms of x is 5x

Mark can remember only the first 4 digits of his friend's phone number. He also knows that the number has 7 digits and that the
denis-greek [22]

Answer:

<em>19800 seconds, or 330 minutes, or 5 hours + 30 minutes</em>

Step-by-step explanation:

<u>Number Permutations</u>

We know the phone number has 7 digits, 4 of which are known by Mark. This leaves him 3 digits to guess with. We also know the last one is not zero. The number can be represented as

XXY

Where X can be any digit from 0 to 9 and Y can be any digit from 1 to 9. The first two can be combined in 10x10 ways, and the last one can be of 9 ways, this gives us 10x10x9 = 900 possible permutations.

If each possible number takes him 22 seconds, every possibility will need

22x900=19800 seconds, or 330 minutes, or 5 hours + 30 minutes

The graph of f(x) = (0.5)x is replaced by the graph of g(x) = (0.5)x − k. If g(x) is obtained by shifting f(x) down by 5 units,
tekilochka [14]

Answer: The value of k is 5 units.

Step-by-step explanation:

Since we have given that

The graph of f(x)=0.5x is replaced by the graph of g(x) = 0.5x-k

If g(x) is obtained by shifting f(x) down by 5 units,

Then the graph of f(x) = 0.5x is replaced by the graph of g(x) = 0.5x-5

Hence, k = 5 units

Therefore, the value of k is 5 units.
