You have two points A ( X;Y) and B ( X ; Y)

slope is : ( Yb -Ya) / (Xb -Xa )

A (1; -8) B ( -5 ; 10)

so : ' (10 - -8 ) / ( -5 - 1) = 18 /-6 = -3

Here are two rectangles.

creativ13 [48]

Answer:

$\frac{Area \:of\: rectangle\: A}{Area \:of\: rectangle\: B} =\frac{4}{3}$

Step-by-step explanation:

Let the length of rectangle A be x units.

So, length of rectangle B

= x + 25% of x

= x + 0.25x

= 1.25x

Let the width of rectangle A be y units

So, Width of rectangle B

$= \frac{3}{5}\times x\\=0.6x$

Area of rectangle A = xy

Area of rectangle B

= 1.25x * 0.6y

= 0.75xy

$\frac{Area \:of\: rectangle\: A}{Area \:of\: rectangle\: B} =\frac{xy}{0.75xy}\\\\\frac{Area \:of\: rectangle\: A}{Area \:of\: rectangle\: B} =\frac{1}{0.75}\\\\\frac{Area \:of\: rectangle\: A}{Area \:of\: rectangle\: B} =\frac{100}{75}\\\\\red{\bold{\frac{Area \:of\: rectangle\: A}{Area \:of\: rectangle\: B} =\frac{4}{3}}} \\\\$

Is (6,7) a solution to the inequality 15x+11y>12

astra-53 [7]

Answer:

(6,7) is a solution

Step-by-step explanation:

To determine if (6,7) is a solution, we substitute the point in and see if the inequality is true

15x+11y>12

15(6) + 11(7) >12

90+77 > 12

167>12

This is true so (6,7) is a solution

D. $3.25 A cell phone at Store A costs $10 less than twice the cost of the same cell phone at Store B. If the phone costs $49.99

BlackZzzverrR [31]

$\begin{gathered} At\text{ Store B = x = \$49.9} \\ \text{while the same cell phone in Store A cost }=\text{ \$2x-\$10} \\ \text{ =\$ 2(49.9) - \$10 } \\ \text{ = \$99.8 - \$10} \\ \text{ =\$89.8} \end{gathered}$

HELP PLZ I NEED THIS DONE BY TMRW

Kazeer [188]

Answer:

0.75ft per square

Step-by-step explanation:

We know that the number of squares is 24 so we need to determine the dimension of 1 square.

We know the width is 4.5 and we also know that there are 6 squares within that area.

Therefore we can use a fraction to find our answer.

$\frac{4.5}{6} > 0.75$
