I think C is 6, I’m not sure if thats right though. But if X=2 and Y=1
6(2)+6(1)= 18
3(2)+2(1)= 8

For an annual membership fee of $500,Mr.Bailey can join a country club that would allow him to play a round of golf for $35. Wit

IRISSAK [1]

Answer:

25 rounds

Step-by-step explanation:

Let

x -----> the number of rounds of golf

y ---> total charges to play

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope or unit rate

b is the y-intercept or initial value

<em>Membership</em>

$y=35x+500$ ----> equation A

The slope is m=$35 per round

The y-intercept b=$500 (annual membership fee)

<em>Non-Membership</em>

$y=55x$ ----> equation B

The slope is m=$55 per round

The y-intercept b=$0

Equate equation A and equation B

$55x=35x+500$

solve for x

$55x-35x=500$

$20x=500$

$x=25\ rounds$

For x=25 rounds the cost to be the same with and without a membership

Please help it would mean a lot to me :)

Answer:

a) TO = OP = 13

b) Height = 12

Step-by-step explanation:

a) Isosceles triangle TOP with base TP = 10 cm, side TO = OP = x cm.

Perimeter of triangle TOP = 36 cm

=> TO + OP + TP = 36

=> x + x + 10 = 36

=> 2x = 26

=> x = 13

=> TO = OP = 13 cm.

b) Apply Pythagorean theorem:

height^2 + (base/2)^2 = side^2 (height^2 + (TP/2)^2 = TO^2)

height^2 + (10/2)^2 = 13^2

height^2 + 25 = 169

height^2 = 144

height = 12

Hope this helps!

Students were asked to write 6x5 + 8x - 3x3 + 7x7 in standard form.

dimulka [17.4K]

Answer:

$7x^{7} + 6x^{5} - 3x^{3} + 8x$

Step-by-step explanation:

Students are asked to write $6x^{5} + 8x - 3x^{3} + 7x^{7}$ in the standard form.

Now, in the standard form of a polynomial the highest power of the variable takes the leftmost position and the lowest power of the variable takes the rightmost position and the power of variable decreases from left to right.

Therefore, the standard form will be $7x^{7} + 6x^{5} - 3x^{3} + 8x$ . (Answer)
