Javier rode his bike for a total of 40 minutes.

Let x be the minutes Javier ride after lunch

Let y be the minutes Javier ride before  lunch

The number of minutes he rode after lunch is 4 times the number of minutes he rode before lunch

x = 4 y

The number of minutes he rode after lunch + number of minutes he rode before lunch = 40

x + y = 40

We know x= 4y

4y + y = 40

5y = 40

y = 8

x= 4y so x= 4(8) = 32

Javier ride  32 minutes after lunch

Answer:

<h2>9.2</h2>

Step-by-step explanation:

The distance formula is:

d = \sqrt{(x2 - x1)^2 + (y2 - y1)^2

-4 - 2 = -6  squared = 36

4 - -3 = 7   squared = 49

36 + 49 = 85

\sqrt{85} = about 9.2

I'm always happy to help :)

The equation V equals pi r squared h, where r represents radius and h represents height, is used to find the volume of a _______
baherus [9]

Answer:

Volume of a cylinder.

Step-by-step explanation:

The given equation is :

V=\pi r^2 h

Where

r is the radius

h is the height

This equation is used to find the volume of a cylinder.

For example, a cylinder having radius of 7 units and height of 10 units, its volume will be :

V=\dfrac{22}{7}\times 7^2\times 10\\\\V=1540\ \text{unit}^2

So, the given equation is used to find the volume of a cylinder.

For the rational expression 2x^2-7x-15/x^2-25, do both of the following,
Mrrafil [7]

Answer:

a. \frac{2x + 3}{x+5}

b. x ≠ -5 (Vertical asymptote) and x ≠ 5 (Hole)

Step-by-step explanation:

Factor the numerator (Grouping):

2x^2 - 7x - 15              

Two numbers that multiply to -30 and add to -7 = -3 and 10

[2x^2 - 10x] + [3x - 15]

(2x + 3)(x - 5)

Factor the denominator (Difference of Two Squares):

x^2 - 25 = (x +5)(x-5)

Factored Expression:

(x - 5) can be factored out of top and bottom as a hole-

\frac{(2x + 3)(x - 5)}{(x + 5)(x - 5)} = \frac{2x + 3}{x+5}

Variable Restrictions:

Denominator ≠ 0

x + 5 = 0\\x = -5

Vertical asymptote at x = -5 ⇒ x ≠ -5
