All you need to do is multiply the amount of gas Tyler used (17.04 gallons) by 6.2 to get the amount of gas Maria used. So 17.04 multiplied by 6.2 = 105.648 gallons of gas.

What is the equation of the line that is perpendicular to the line y=*x+10 and passes through the point (15,-5)?

ivanzaharov [21]

Answer:

Slope of the line y = x + 10 is 1. So, any straight line perpendicular to this must be having slope of (-1).

Let, the line be y = - x + b and it passes through (15, -5).

So, 15 = 5 + b

b = 10.

So, equation of that line: y = -x + 10

Or, x + y = 10.

Y-intercept of the line = 10 units.

Match the equation below with the following graph.

Lemur [1.5K]

Answer:

2x+4

Step-by-step explanation:

The equation of the line in point-slope form is expressed as;

y - y0 = m(x-x0)

Using the coordinates (0,4) and (-2, 0)

Slope = 0-4/-2-0

slope = -4/-2

slope = 2

Substitute m = 2 and the point (0,4) into the formula;

y - 4 = 2(x-0)

y - 4 = 2x

since y = 4 + 2x

y = 2(x+2)

Hence the required equation is 2x+4

Find the length x to the nearest whole number. A right triangle has a vertical leg of length x units, a base leg with a length o

wel

Complete Question

The diagram for this question is shown on the first uploaded image

Answer:

The value of x is $x = 274 \ unites$

Step-by-step explanation:

From the question we are told that

The length of the vertical length is $x$

The length of the base leg is L = 330 + d units

The length of the bisecting line segment is h

The base angle is $\theta = 28^o$

The angle between d and line segment is $\theta_1 = 56^o$

For the first angle

$Tan \theta_1 = \frac{x}{d}$

=> $d = \frac{x}{Tan \theta _1}$

For the whole big triangle

$Tan \theta = \frac{x}{330 + d}$

=> $d = \frac{x}{Tan \theta } -330$

So equating the both d

$\frac{x}{Tan \theta _1} = \frac{x}{Tan \theta } -330$

Substitute values

$\frac{x}{Tan (56)} = \frac{x}{Tan (28) } -330$

$0.6745 x = 1.880x -330$

$1.20549 x = 330$

$x = 274 \ unites$

What is the sum of the rational expressions below? X/4 + 3/5x

Andrew [12]

Answer:

The answer is $\frac{5x^2+12}{20x}$ .

Step-by-step explanation:

Given:

X/4 + 3/5x.

Now, to find the sum of the rational expressions.

$\frac{x}{4} +\frac{3}{5x}$

So, to solve it by adding:

$\frac{x}{4} +\frac{3}{5x}$

$=\frac{5x\times x+3\times 4}{5x(4)}$

$=\frac{5x^2+12}{20x}$

Therefore, the answer is $\frac{5x^2+12}{20x}$ .
