A taxi cab driver charges a $2.00 initial fee and $1.75 for each mile.
umka21 [38]

1. She can travel 18 miles. Subtract 35 - 2 (initial fee) to have 33. divide 33 by 1.75 to get 18.85. To check how much her total would be, use inverse operations. 18.85 * 1.75 = 32.9875. 32.9875 + 2 = 34.9875. It is barely under $35 but still in her budget.

2. 20m * $1.75 = $35. $70 - $35 = $35. Yes, she can cover the fare. Samantha has more than needed. She can afford the taxi fare and still have money left for future use.

The diagram shows the graph of y = 2x + c, where c is a constant find the value of K.​
mote1985 [20]

Answer:

k=\frac{13}{2}

Step-by-step explanation:

The equation y=2x+c is a <em>linear equation</em>. By definition, the independent term on this equation (that is, the number that is not being multiplied by x) is the <em>y-intercept</em>, which is a fancy way of saying "the point where the line crosses the y-axis".

By looking at the equation, we know that our y-intercept is <em>c. </em>By looking at the graph, we can see that the y-intercept is -3. Therefore, c=-3 and we get the complete version of our linear equation:

y=2x-3

Now, looking at the graph we can see that the point (k,10) lies on the line of the equation, which means that the point is a solution to our equation. All we have to do is replace x and y by the values of the given point (which are k and 10, respectively), and then solve for k:

10=2k-3\\10+3=2k\\13=2k\\2k=13\\k=\frac{13}{2}

And we are done!

lana [24]

Answer:

5 {x}^{2}  + 2x = 7x + 3x \\ 5 {x}^{2}  + 2x = 10x \\ 5 {x}^{2}  = 10x - 2x \\ 5 {x}^{2}  = 8x \\ 5x = 8 \\ x =  \frac{8}{5}  = 1.6 \\ thank \: you
