Nick can read 3 pages in 1 minute. write the ordered pairs for nick reading 0,1,2 and 3 min

1 answer:

4 0

For 0 minutes, it would be 0 minutes (obviously)
for 1 minute, it would be 3
for 2 minutes, it would be 6 pages
and finally, 3 minutes, will be 9.
to get the answers, you would just have to add 3, since every minute, nick reads 3 pages.

The length of the longer leg of a right triangle is 6 cm more than twice the length of the shorter leg. The length of the hypote

iragen [17]

Let x = the shorter leg
2x + 6 is the longer leg
2x + 9 is the hypotenuse

We now do the Pythagorean Theorem of $a^{2}+b^{2} = c^{2}$

$x^{2} + (2x+6)^{2} = (2x+9)^{2}$

Multiply out to get:

$x^{2} +4 x^{2} +24x+36=4 x^{2} +36x+81$

The $4 x^{2}$ will cancel out each other when you combine like terms to get all the terms on one side of the equal sign.

Combine like terms with the rest to end with $x^{2} -12x-45=0$

Factor this to get $(x-15)(x+3) = 0$ then set each factor equal to zero.

You end up with two solutions, x = 15 and x = - 3 HOWEVER distance cannot be measure in negatives so that answer will not work so x = 15. Now plug into our given information.

The short leg is 15 cm long.
The longer leg of 2(15) + 6 = 36 cm long
The hypotenuse of 2(15) + 9 = 39 cm long.

You can check your answers by plugging them into the Pythagorean Theorem again.

Help me fast!! I need to get a 90 on it

QveST [7]

Answer:

-7/2

Step-by-step explanation:

Slope equals rise (vertical or y axis) over run (horizontal or x axis). So you need to find two points on this line that cross directly where the grid lines cross. If you look closely, the line seems to cross directly at ( -6, 3 ) and again at ( -4, -4). So the rise values (y axis) are 3 and -4 which is a total of 7 units apart.

The run values are -6 and -4 which is a total of 2 units apart.

So your slope with be 7/2 but since it slopes downward to the right, it is a negative slope.

The answer would be negative 7/2

Write an expression that can be used to solve the problem.

Ymorist [56]

The answer is going to be <span>B. 160/8. divide 160/8 to get 20 pages so he reads 20 pages each day and you can check by multiplying 20*8=160</span><span />
