A girl buys a monthly bus​ pass, which entitles her to unlimited bus​ travel, for ​$40 per month. Without the pass each bus ride costs ​$1.60. How many rides per month would she have to take so that the cost of the rides without the bus pass is equal to the total cost of the rides with the bus​ pass?
The number of rides at which the unlimited ride pass equals the cost of individual ride purchases is ?.

Answers

Answer: 25 Rides

Step-by-step explanation:

Forty (cost of pass per month) divided by 1.60 (Cost of rides) = 25 rides until the cost of the rides equals the price of the pass.

What is (0,5) and (2,14) in slope intercept form

Answers

Answer:

y = 9/2x + 5

Step-by-step explanation:

ok first find the slope with equation (x2 - x1 over y2 - y1)

14 - 5 = 9/

2 - 0 2

so 9/2 is your slope so now pick one of the points (let's do 0, 5) and plug that into the slope intercept form (y = mx+b)

5 = 9/2(0)+b

9/2 • 0 = 0 so b = 5

so the answer is y = 9/2x + 5. hope this helps!

2x^3-3x^2+kx-1 is divided (x-1),the remainder is 2 find k

Answers

Answer:

k = 4

Step-by-step explanation:

if f(x) is divided by (x - h) then f(h) is the remainder

f(x) = 2x³ - 3x² + kx - 1

divided by (x - 1) , so h = 1 , then

2(1)³ - 3(1)² + k(1) - 1 = 2

2 - 3 + k - 1 = 2

- 2 + k = 2 ( add 2 to both sides )

k = 4

If y = xy + x2 + 1, then when x=-1,
dy/dx

Answers

Given y = xy + x^2 +1, first find y = f(x) = (x^2 + 1) / (1 - x). Then use the quotient rule for derivatives.

dy/dx = [( 1 - x)( 2x) - (x^2 + 1)(-1)] / (1 - x)^2. Substitute the value of x = -1 into the above derivative and get -1/2.

If y = xy + x² + 1, then when x=-1,

dy/dx = -1/2

What is Derivatives?

The rate of change of a function with respect to a variable are called Derivatives.

Given that, y = xy + x² + 1

Put x = -1 we get,

y = -1y + (-1)² + 1

y = -y + 1 + 1

y = 1

Now Differentiating the given equation w.r.t x

dy/dx = xdy/dx + y + 2x

dy/dx - xdy/dx = y + 2x

dy/dx (1 - x) = y + 2x

dy/dx = (y + 2x)/(1 - x)

Put x = -1 and y = 1 we get

dy/dx = (1 + 2(-1))/(1 - (-1))

dy/dx = -1/2

Hence, y = xy + x² + 1, then when x=-1,

dy/dx = -1/2

Answers

Answer: 38 meters per second

Step-by-step explanation:

Rachel's speed is 38 m/s.

What is Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

D = -38t + 220

So, t = 1

D = -38t + 220

D = -38(1) + 220

D = -38+ 200

D = 182 m

So, v = [tex](D_0 - D_1)[/tex] / t

v = ( 220- 182) /1

v = 38 m/s

Hence, Rachel's speed is 38 m/s.

Answers

x - 2 + x - 1 + x = 5x - 41 , x being the largest number. The largest number is 19.

The larger of two numbers is 5 more than the smaller. The smaller number plus the larger equals 100. Find the number.

Answers

Answer:

Smaller number-47.5

Larger number-52.5

Step-by-step explanation:

We will make the smaller number x. If the smaller number is x, then the larger number will be equal to x+5. We also know that when we add the two numbers, we get 100. We can make the equation

x+x+5=100

100-5=95

2x=95

95/2=47.5

x=47.5

The smaller number equals 47.5 and the larger number is 47.5+5 which equals 52.5

Graph the line that passes through the two points.(1, 5/2), (−1/2,−1/4)

Answers

Answer:

To find the slope of a line, simply use the slope formula [(y2-y2)/(x2-x1)].

To find the y-intercept, simply plug in point values to solve for b.

The line that passes through the two points (1, 5/2) and (-1/2,-1/4) is y=1.8x+0.7.

The given coordinate points are (1, 5/2) and (-1/2,-1/4).

What is slope of a line?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The formula to find the slope of a line is slope = (y2-y1)/(x2-x1)

Substitute (x1, y1)=(1, 5/2)=(1, 2.5) and (x2, y2)=(-1/2, -1/4)=(-0.5, -0.25) in slope formula, we get

Slope =(-0.25-2.5)/(-0.5-1)

= -2.75/(-1.5)

= 1.8

Put m=1.8 and (x, y)=(1, 2.5) in y=mx+c, we get

2.5=1.8×1+c

c=0.7

So, equation is y=1.8x+0.7

Hence, the line that passes through the two points (1, 5/2) and (-1/2,-1/4) is y=1.8x+0.7.

Triangle abc is an isosceles triangle in which angle b = angle c and l and m are points on ab and ac respectively such that lm parallel to bc. If angle a = 50 degree find angle lmc

Answers

Answer:

∵ ABC is an isosceles  triangle

∵ m∠b = m∠c

∴ m∠b and m∠c = 180 - m∠a/2

= 180 - 50/2

= 130 /2

= 65°

∵ ∠c and ∠AMI are corresponding angles

∵ m∠AMl = m∠c = 65°  (1)

From (1)

∵ ∠AMC is striaght angle

∴ m∠IMC = 180 - m∠AMI

m∠IMC = 180 - 65

m∠IMC = 115°

The graph of which inequality has its vertex at (2 1/2, 5)?
The correct answer to this is y>|2x-5|+5.
My question is where did the 2 1/2 come from in the vertex?

Answers

Answer:

77777

Step-by-step explanation:

In this case, the vertex is the lowest point of the V shaped curve.

The goal is to get the stuff inside the absolute value (the 2x-5) to be as small as possible, so we can get to the lowest point. In terms of absolute value, we want the 2x-5 to be equal to 0

This allows us to set up the equation below and solve for x.

2x-5 = 0

2x = 5

x = 5/2

x = (4+1)/2

x = 4/2 + 1/2

x = 2 + 1/2

x = 2 & 1/2

Determine the domain and range of the given function:

This is just a garden-variety polynomial. There are no denominators (so no division-by-zero problems) and no radicals (so no square-root-of-a-negative problems). There are no problems with a polynomial. There are no values that I can't plug in for x. When I have a polynomial, the answer for the domain is always:

the domain is "all x".

The range will vary from polynomial to polynomial, and they probably won't even ask, but when they do, I look at the picture:
