Answer and Step-by-step explanation:

1-6

a.

What you can do is plug in 6 and start by doing the first machine first, then the second. If this doesn't work, do the second machine, then the first machine.

<em><u>The order that works is second machine, then first machine.</u></em>

<u>Second Machine:</u>

y = $(6)^{2} -6$ = 36 - 6 = 30

Plug into first machine now.

<u>First Machine:</u>

y = $\sqrt{(30) - 5} = \sqrt{25} = 5$

We see that the result is 5.

b. <em><u>If we were to do the order of second machine, then first machine, we will never get a negative result (or -5 for that matter), due to the fact that you can't algebraically square root a negative number.</u></em>

<em><u>However, if we were to do the order of first machine, second machine, we can get a negative number. To get -5, we plug in 6 for x in the first machine, getting an answer of 1. We plug this into the second machine, getting 1^2 - 6, which results in -5.</u></em>

1-7. The absolute value of a value is the positive version of that value.

a. |54| = <em><u>54</u></em>

b. $-|-7\frac{3}{5}|$ = $-7\frac{3}{5}$

c. |3| - |-1| = 3 - 1 = <em><u>2</u></em>

d. |2.2 - 5.13| = |-2.93| = <em><u>2.93</u></em>

<u>(6 boxes on each side)</u>

b.<em><u> The amount of squares on each side of the figure increases by 1.</u></em>

c. <em><u>There would be 1 square, because we know that the pattern is there is 2 squares added to the next figure, 1 at each end. If we go back a figure, we take away 2 squares.</u></em>

1-9.

a. -42 - 17 = <em><u>-59</u></em>

b. 8 - (-9) = 8 + 9 = <em><u>17</u></em>

c. 8(-9) = <em><u>-72</u></em>

d. -42 ÷ (-7) = <em><u>6</u></em>

e. -2(-3)(-4) = 6(-4) = <em><u>24</u></em>

f. -18 - 7 = <em><u>-25</u></em>

g. $(-5)^{2}$ = <em><u>25</u></em>

h. $-5^{2} = -(5)^2 = -(25)$ = <em><u>-25</u></em>

i. $\sqrt{49}$ = <em><u>7</u></em>

1-10. x = 2 Plug 2 in for x, then solve.

a. y = 7 - 3(2) = 7 - 6 = <em><u>1</u></em>

b. y = $(2)^2 -1$ = 4 - 1 = <em><u>3</u></em>

c. y = $\frac{18}{2}$ = <em><u>9</u></em>

On a coordinate plane, triangle R S T has points (negative 5, 6), (3, 4), and (negative 2, 2). Which expression can be used to f

pav-90 [236]

The area of a triangle is the amount of space on the triangle

The expression that represents the area of the triangle is $A = \frac 12|-5(2 -4) +3(2 -6) -2(4 -6)|$

The coordinates of the triangle are given as:

$R = (-5,6)$

$S = (3,4)$

$T = (-2,2)$

The area (A) of a triangle from its coordinates or vertices are:

$A = \frac 12|x_1(y_3 -y_2) +x_2(y_3 -y_1) + x_3(y_2 -y_1)|$

Substitute values for x's and y's

$A = \frac 12|-5(2 -4) +3(2 -6) -2(4 -6)|$

Hence, the expression that represents the area of the triangle is $A = \frac 12|-5(2 -4) +3(2 -6) -2(4 -6)|$
