Answer:

y=2

x=4

Step-by-step explanation:

So for a y=2 then y=2x-6

We already know the value of y, 2

To find the value of x you substitute the y value into the second equation

So 2=2x-6 (then move -6 to the other side of the equation, +6)

8=2x (move 2 to the other side, ÷2)

So x=4

I hope this helped :)

Answer: 676

Step-by-step explanation:

The total number of letters in English alphabet {From A to Z} = 26

We assume that the repetition of letters is allowed.

If we fix H at the first position , then the number of ways to make three-letter strings that begin with H is given by :-

$1\times26\times26=676$

Hence, the number of ways to make three-letter strings that begin with H is 676.

Use the following diagrams for questions 3 and 4 questions in picture please help

ella [17]

Answer:The answer is x=84

Step-by-step explanation:

The lines p and f are parallel and t is the transverse line

Here the corresponding angles are equal

i.e. the angle made by the transverse line with each of the parallel line

is equal

So in fig 1 -60

fig 2 -124

fig 3 -135

So x=84 [corresponding angles are equal]
