The cost of a car rental is ​$30per day plus per mile. You are on a daily budget of ​$75. Write and solve an inequality to find the greatest distance you can drive each day while staying within your budget. Use pencil and paper. Find 2 other​ two-step inequalities with the same solutions.

Answers

Answer:

Step-by-step explanation:

Cost ≤ per day amount + daily mileage amount.   * miles

75 ≥ 30 + daily mileage amount * miles

That's as far as I can take you. Two other equations are impossible without the daily mileage amount.

I can make one up. Suppose it is 75 cents a mile

75 ≥ 30 + 0.75 * x       Subtract 30 from both sides

75 - 30 ≥ 0.75*x

40 ≥ 0.75*x                 Divide by 0.75

40/0.75 ≥ x

53.33 miles = x  

Anything more and you are going over budget. Anything less is fine.

This is enough to get you started without knowing what the rate per mile is.

the tunnel
-b State a geometric model that could be used to
represent a truck passing through the tunnel.

My buddy what's popping??

Step-by-step explanation:

Those coming from the Pest end had to walk round the Castle Hill on the Buda side to be able to proceed northwards. On 10 February 1853, four years after the completion of the Chain Bridge, the building of a tunnel leading through the hill was started to the plans of Adam Clark. On 6 March 1856, the tunnel was opened for foot traffic, and on 30 April 1857 also for motor traffic. Being 350 meters in length, it leads through under the Buda Castle to the other side of the hill. Its length is approximately identical to that of the Chain Bridge, prompting anecdotes according to which the tunnel has only been built so that in rainy weather, the Chain Bridge can be shoved in and be protected from wet conditions. The entry of the tunnel at its Chain Bridge end was also fittingly designed in classicist style.

Give the equation of the line in
slope intercept form.
y = [?]x + []
Enter the number that belongs in the green box.

Answers

Answer:

y = 3x - 2

Step-by-step explanation:

The equation of a line is y = mx + c where m is the slope of the line and c is the y-intercept. I will be calculating the slope of the line using the points (1, 1) and (2, 4).

Slope = [tex]\frac{rise}{run}[/tex]

          = [tex]\frac{4-1}{2-1}[/tex]

          = 3

Based on the graph, the y-intercept is (-2) so the equation of the line is:

y = 3x - 2

The slope is y= 3x-2 is correcttt

A.) This system has no solutions.

Step-by-step explanation:

y = 1/2x + 4

-1/2x + y = -5

-1/2x + (1/2x + 4) = -5

4 = -5

The system has no solutions, if we graph it, we get that it has the same slope with two different y-intercepts, these two are parallel. These two points will never meet at a point.

Answer:

use the relationship between coefficients of a pair of linear equations for no solutions i.e. a1/a2 equal to b1/b2 not equal to c1/c2 .

Here, a is coefficient of x and b is coefficient of y and c is constant term in both equation but make sure that you put the values of a1,a2,b1,b2,c1 and c2 after converting both equation in the form ax+by+c=0 with proper sign and here y=1/2(x) +4 is equation 1 and other is equation 2

Each person in a certain group supports only one of the two candidates R and T. Of the people in the group, 45 percent support Candidate R and the rest support Candidate T. How many people in the group are in favor of a flat tax

Answers

Missing Information:

Of the people in the group who support Candidate R, 58 percent are in favor of flat tax Of the people in the group who support Candidate T, 22 are in favor of a flat tax.

Answer:

[tex]Total = 26.1\%N + 22[/tex]

Step-by-step explanation:

Given

[tex]R = 45\%[/tex] --  [tex]Percentage[/tex] [tex]of\ R[/tex] in the total population

[tex]Favor\ Flat\ Tax = 58\%[/tex] in group R

[tex]Favor\ Flat\ Tax = 22[/tex] in group T

Required

Determine the number of people that supports T

First, the proportion of those that supports flax rate in R needs to be calculated.

[tex]Proportion = 45\% * 58\%[/tex]

[tex]Proportion = 26.1\%[/tex]

So, those that favor flat tax rate in group R are:

[tex]Favor\ Flat\ Tax = 26.1\%N[/tex]

Where N represents the total population.

Total number of people that supports the flax tax rate is gotten by adding  people that support flat tax rate in each group.

[tex]Total = Group\ R + Group\ T[/tex]

[tex]Total = 26.1\%N + 22[/tex]
