Mariana [72]
Y = 3x....where y is # pgs read and x = # of minutes

0 minutes....x = 0
y = 3(0)
y = 0
ordered pair (0,0)

1 minute...x = 1
y = 3(1)
y = 3
ordered pair (1,3)

2 minutes...x = 2
y = 3(2)
y = 6
ordered pair (2,6)

3 minutes...x = 3
y = 3(3)
y = 9

First, rewrite 5/9 and 11/21 so they have a common denominator. Then, use to order 5/9 and 11/21.
spayn [35]

5/9 and 11/21

LCM of the denominators is 63

changing their denominators to all have a common denominator of 63:

5(7)/63 = 35/63

11(3)/63 = 33/63

from the above;

5/9 > 11/21.

Multiply: (9x^2y^3)(7xy^2)
MrRissso [65]
Remember
(ab)(cd)=(a)(b)(c)(d)=(ac)(bd),
and
(x^m)(x^n)=x^(m+n)

(9x^2y^3)(7xy^2)=
(9)(x^2)(y^3)(7)(x)(y^2)=
(9)(7)(x^2)(x)(y^3)(y^2)=
(63)(x^3)(y^5)=
63x^3y^5

On one highway, Gabriela noticed that they passed mile marker 123 at 1:00. She then saw that they reached mile marker 277at 3:00
Elena L [17]

<u>Given</u>:

Let time be the independent variable.

Let mile marker be the dependent variable.

On one highway, Gabriela noticed that they passed mile marker 123 at 1:00. She then saw that they reached mile marker 277 at 3:00 and Mr. Morales was driving at a constant speed.

The coordinates of the points on this line are (1,123) and (3,277)

We need to determine the slope of the line.

<u>Slope of the line:</u>

The slope of the line can be determined using the formula,

m=\frac{y_2-y_1}{x_2-x_1}

Substituting the points (1,123) and (3,277) in the above formula, we get;

m=\frac{277-123}{3-2}

m=\frac{154}{1}

m=154

Therefore, the value of the slope of this line is 154.
