You ride an express bus from the center of town to your street. You have two payment options. Option A is to buy a monthly pass

34kurt

Answer:

Step-by-step explanation:

Let x represent the number of miles after which the cost of both options will be the same.

You have two payment options. Option A is to buy a monthly pass for $30 and pay $0.80 per ride. This means that the total amount that you would pay for x miles if you use this option is

0.8x + 30

Option B is to pay $2.30 per ride. This means that the total amount that you would pay for x miles if you use this option is

2.3x

An equation to show after how many rides the cost will be the same would be

0.8x + 30 = 2.3x

2.3x - 0.8x = 30

1.5x = 30

Slope 8 ; through (4,3)

Reptile [31]

Answer:

y=8x-29

Step-by-step explanation:

Since we know the slope (m) is 8, we can plug it in the slope-intercept formula y=mx+b, making y=8x+b.

Now we need to find the y-intercept (b). To do that, you would need to plug in the points given to you, which were (4,3).

x=4, y=3... so 3=8(4)+b

Now you can solve for the variable b to find the y-intercept.

3=8(4)+b, multiply...

3=32+b, subtract 32 on both sides...

-29=b

Therefore, the y-intercept, or b, is -29.

The equation would be y=8x-29

PLZ HELP ME what is the value of y^-5 / x^-3 for x=2 and y =-4 a)-1/128 b)10/3 c) -128 d) 128

Tomtit [17]

1st, substitute x and y with 2 and -4, which'd be $\frac{-4^{-5}}{2^{-3}}$ .
Then, simplify, to get $-\frac{1}{128}$ .
This would be -0.0078125 in decimal form, or - 1/128 in fraction form.

Hope this helps! ^^

The answer to the question above accurate please

SashulF [63]

Answer:

x = 132 degrees

Step-by-step explanation:

To help explain, lets add some letters to designate those line intersections.

Starting at x, label that intersection O, then go up-right to that intersection and label that P, then go down-right to that intersection and label that Q, then go up-right and name that R, then go down-right and label that S, finally go right to that intersection and label that T.

Angle TRS = 12 degrees because isosceles triangle so TRS = a = 12 degrees.

Angle RST = 180-12-12 = 156 degrees.

Angle QSR is supplementary to RST so it is 24 degrees.

Angle RQS = 24 degrees because isosceles.

Angle QRS = 180-24-24 = 132 degrees.

Angle PRQ = 180-12-132 = 36 degrees.

Angle PRQ = 36 degrees because isosceles.

Angle PQR = 180-36-36 = 108 degrees.

Angle PQO = 180-24-108 = 48 degrees.

Angle POQ = 48 degrees because isosceles.

Angle x = 180 -48 = 132 degrees because it is supplementary.

Solve. −6=b2 12 3 –3 –12

klemol [59]

Answer:

b = -3

Step-by-step explanation:

-6 = b2 is the same thing as -6 = 2b to be precise. Divide 2 on both sides to get -3 as your b value.
