Answer:

$16.8

Step-by-step explanation:

Given data

We have the given function as

C= 1.80 + 1.5d

Let us substitute the value of d=10 in the expression

C= 1.80 + 1.5*10

C=1.80+15

C=16.8

Hence the cost of the ride for 10 miles is $16.8

Solve x2 + 1/2x +1/16=4/9
kolezko [41]

<u>Answer:</u>

x = 0.417 or x = -0.917

<u>Step-by-step explanation:</u>

We are given the following expression and we are to solve it for the variable x:

x ^2 + \frac { 1 } { 2 } x + \frac { 1 } { 1 6 } = \frac { 4 } { 9 }

We will find the least common multiple of 2. 6 and 9:

x^2 \times 144 +\frac{1}{2}x \times 144 +\frac{1}{16} \times 144 = \frac{4}{9} \times 144

Simplifying it to get:

144x^2+72x+9=64

144x^2+72x+9-64=0

144x^2+72x-55=0

Using the quadratic formula to solve for x:

x=\frac{-b \pm\sqrt{b^2-4ac} }{2a}

x=\frac{-72 \pm\sqrt{72^2-4(144)(-55)} }{2a}

x=\frac{5}{12} or 0.417

x=-\frac{11}{12} or -0.917

Rewrite the following equation in slope-inte
Nonamiya [84]

Answer:

y = 13x + 86

Step-by-step explanation:

y−8 =13(x+6); distribute the 13

y - 8 = 13x + 78; now add 8 to both sides

y = 13x + 86; this is the slope intercept form

For each of the solutions of the equations find two consecutive integers between which the solution is located.
adoni [48]

Using squares of integers numbers, it is found that the solution of the equation is located between the integers x = 1 and x = 2.

The equation given is:

x^2 = 3

The solution of the equation given is:

x = \sqrt{3}

The squares of the integers numbers until the square root of 3 are:

1^2 = 1

2^2 = 4

Since 1 < 3 < 4, the square root of 3, which is the solution to the equation, is located between the integers x = 1 and x = 2.
