Bisectors are lines that divide an angle into two equal parts. The value of x of OQ is equal to PO is 8

Angle bisectors

Bisectors are lines that divide an angle into two equal parts. If RS is the segment bisector and given the following parameters:

OQ = 32

PO = 4x,

This shows that OQ = PO that is:

32 = 4x

Swap

4x = 32
x = 8

Hence the value of x of OQ is equal to PO is 8

If x = 2y then solve 5y-x in terms of y find the values of these expressions when y =2​

Answers

Answer:

Step-by-step explanation:

x= 2y

y=2

5y - x

5y - 2y

5(2) - 2(2)

10 - 4

6

brainliest is appreciated

If x = 2y then, 5y - x in terms of y is equal to 3y and when y = 2, the value of 5y - x is 6.

To solve 5y - x in terms of y, we need to substitute the value of x in terms of y. Given that x = 2y, we can replace x with 2y in the expression 5y - x:

5y - x = 5y - (2y)

Now we simplify the expression by subtracting 2y from 5y:

5y - (2y) = 3y

Therefore, 5y - x in terms of y is equal to 3y.

To find the value of the expression when y = 2, we substitute y = 2 into the expression:

3y = 3 * 2 = 6

Thus, when y = 2, the value of 5y - x is 6.

16. There are 36 tables set up for the graduation reception. Each table is
8 feet long. The tables will be covered with paper tablecloths that extend
an extra 3 inches over each end (so they can be taped underneath). What
is the total length of paper needed to cover all the tables?

Answers

We have that the total length of paper needed to cover all the tables is

[tex]X=288.5ft[/tex]

From the question we are told that:

Number of tables [tex]n=36[/tex]

Length of table[tex]l=8[/tex]

Extension [tex]e=3 inch =>0.25feet[/tex]

Generally, the equation for the Total length  tables is mathematically given by

[tex]l_t=n*l\\\\l_t=36*8[/tex]

[tex]l_t=288ft[/tex]

Therefore with an extension of 0.25ft at both end we have the Total length of  tablecloths to be

[tex]X=l_t+2(e)\\\\X=288ft+2(0.25)[/tex]

[tex]X=288.5ft[/tex]

In conclusion

The total length of paper needed to cover all the tables is

[tex]X=288.5ft[/tex]

What is the equation of a line that passes through (4, 3) and has a slope of 2?
Oy= 2x – 11
Oy=2x-1
Oy= 22 – 5
y= 22 - 7

Answers

Answer:

[tex]y=2x-5[/tex]

Step-by-step explanation:

Hi there!

Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)

We're given that the slope is 2. Plug this into [tex]y=mx+b[/tex] as m:

[tex]y=2x+b[/tex]

Now, to solve for the b, plug in the point (4,3):

[tex]3=2(4)+b\\3=8+b\\3-8=b\\-5=b[/tex]

Therefore, the y-intercept is -5. Plug this back into [tex]y=2x+b[/tex] as b:

[tex]y=2x+(-5)\\y=2x-5[/tex]

I hope this helps!

Given :-

(x,y) = (4,3)

m = 2

Solution :-

We know that

y = 2x + b

3 = 2(4) + b

3 = 8 + b

3 - 8 = b

-5 = b

Now

We need to find the equation

Equation = y = 2x + b

We have

x = x

y = ?

b = -5

y = 2(x) + (-5)

y = 2(x) - 5

y = 2x - 5

Step-by-step explanation:

to solve this equation you first have to group the like terms

6x-3+3x=60+2x

6x+3x-2x=60+3

7x=63

then you divide both sides by 7 inorder to remain with the variable x on one side

7x/7=63/7

if 2y-5x+10=0, find.
(i)y, when x=2
(ii)x, when y=5​

Answers

Answer:

When x = 2, y = 0When y = 5, x = 4

Step-by-step explanation:

PART I: Value of y, when x = 2

Given information

x = 2

Given expression

2y - 5x + 10 = 0

Substitute values into the expression

2y - 5(2) + 10 = 0

Simplify by multiplication

2y - 10 + 10 = 0

2y = 0

Divide 2 on both sides

2y / 2 = 0 / 2

[tex]\boxed{y=0}[/tex]

-----------------------------------------------------------------

PART II: Value of x, when y = 5

Given information

y = 5

Given expression

2y - 5x + 10 = 0

Substitute values into the expression

2(5) - 5x + 10 = 0

Simplify by multiplication

10 - 5x + 10 = 0

20 - 5x = 0

Add 5x on both sides

20 - 5x + 5x = 0 + 5x

20 = 5x

Divide 5 on both sides

20 / 5 = 5x / 5

[tex]\boxed{x=4}[/tex]

Hope this helps!! :)

Please let me know if you have any questions

Answer:

(i) x = 2

Substituting value in the equation,

2y - 5(2) + 10 = 0

2y - 10 + 10 = 0

2y = 0

y = 0

(ii) y = 5

Substituting value in the equation,

2(5) - 5x + 10 = 0

10 - 5x + 10 = 0

20 - 5x = 0

20 = 5x

5x = 20

x = 20/5

x = 4
