Answer:

Step-by-step explanation:

Difference of squares: (a^2 - b^2) = (a - b)(a + b)

(144x^2 - 49) = (12x - 7) (12x + 7)

Answer:

A. (12x - 7) (12x + 7)

Step-by-step explanation:

144x^2 - 49

Rewriting

(12x)^2 - 7^2

Recognizing this is the difference of squares

a^2 - b^2 = ( a-b) (a+b)

( 12x-7) (12x+7)

What linear function represents the line given by the point slope equation y+7= 2/3(x+6)?

aleksandrvk [35]

Answer:

The graph of the line in the attached figure

Step-by-step explanation:

we have

$y+7=\frac{2}{3}(x+6)$

This is the equation of a line into point slope form

The slope is $m=\frac{2}{3}$

The line pass through the point (-6,-7)

To graph the line find the y-intercept

Remember that

The y-intercept of the line is the value of y when the value of x is equal to zero

For x=0

$y+7=\frac{2}{3}(0+6)$

$y+7=\frac{2}{3}(6)$

$y+7=4$

$y=4-7=-3$

The y-intercept is the point (0,-3)

with the point (-6,-7) and (0,-3) plot the line

see the attached figure

Clara's class is going on a trip to the local science museum. Twenty-five students, one teacher, and three parents are going on

yarga [219]

Answer:

$107.50

Step-by-step explanation:

$3.50 = 1 STUDENT

$5.00 = 1 ADULT

TWENTY FIVE STUDENTS = $3.50 × 25 = $87.50

FOUR ADULTS (ONE TEACHER AND THREE PARENTS) = $5.00 × 4 = $20.00

TOTAL COST = $87.50 + $20.00 = $107.50
