A car travel 140 miles in 3 hours (with a constant speed). How far can it travel in 7 hours (with the same speed)?

Answer:

shape is a Pentagon (has 5 sides)

Sum of interior angles is 540°

x = 90°

m∠B = 90°

m∠E = 100°

Step-by-step explanation:

to find the sum of the interior angles you take the number of sides, deduct two, and multiply by 180

a 5-sided figure would be (n - 2)·180° = 3(180) = 540°

add together all five angle measures and set equal to 540; combine like terms and solve for 'x'

220 + 130 + 130 + x + x + 10 = 540

350 + 2x + 10 = 540

2x + 360 = 540

2x = 180

x = 90

Answer: 254.34 ^ 2

Step-by-step explanation:

To find the area of the circle use its formula

A = Pi * R^2                /  Area equals pie times radius squared

The two circles diameter combined is 18 meaning the radius is 9

So we plug 9 into the formula

A = 3.14 * 9^2

A = 3.14 * 81

A = 254.34 ^ 2

Step-by-step explanation:

x - y = 5 - -5

       = 5 + 5

       = 10

Answer: 10

Step-by-step explanation:

5-(-5) is addition. 5+5=10

Step-by-step explanation:

2(x-3)=5(x-3)+10

=> 2x - 6 = 5x - 15 + 10

=> -6 + 15 -10 = 5x - 2x

=> 5x -2x = 15 - 6 - 10

=> 3x = 15 - 16

=> 3x = -1

Answer:

x value of vertical asymptote and y value of horizontal asymptote

Step-by-step explanation:

The graph of 1/x approaches infinity as x approaches 0 (the vertical asymptote)

As x gets either bigger or smaller, 1/x approaches the x-axis (from above on the positive side, from below on the negative side) (the horizontal asymptote)

Consider 1/(x-5) + 2, at what value of x does the graph 'go nuts' ?

When the bottom of the fraction becomes 0, x - 5 becomes 0 when x = 5, so the vertical asymptote of g(x) is at x=5

What value of y does f(x) approach as x gets more positive or more negative - as x gets bigger (as an example), y approaches 0

What y value does g(x) approach as x gets bigger?  Well, as x gets big, 1/(x-5) gets small, approaching 0.  The smallest 0 + 2 can get is 2, so y=2 is the horizontal asymptote

Answer:

D I dont know if im right though

Step-by-step explanation:

The system of equations are same and graphs of the equations are the same line because the equations have the same slope and same y-intercept. The system has infinitely many solutions.

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

The first equation is -3x + 3y = 12  be equation (1)  

y = x + 4   be equation (2)

Adding 3x on both sides , we get

3y = 3x + 12

Divide by 3 on both sides , we get

y = x + 4   be equation (3)

So , the equation ( 2 ) is same as equation ( 3 )

Now , the slope of the equation is m = 1 and the y intercept is b = 4

Hence , the equations have infinite solutions
