(5.2)

109
(-3,-1)
a. The equation of line k in slope-intercept form is
(Use integers or fractions for any numbers in the equation. Simplify your answer.)
Answers
a) The equation of line k is:
[tex]y = -\frac{202}{167}x + \frac{598}{167}[/tex]
b) The equation of line j is:
[tex]y = \frac{167}{202}x + \frac{1546}{202}[/tex]
The equation of a line, in slope-intercept formula, is given by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change.b is the y-intercept, which is the value of y when x = 0.Item a:
Line k intersects line m with an angle of 109º, thus:[tex]\tan{109^{\circ}} = \frac{m_2 - m_1}{1 + m_1m_2}[/tex]
In which [tex]m_1[/tex] and [tex]m_2[/tex] are the slopes of k and m.
Line k goes through points (-3,-1) and (5,2), thus, it's slope is:[tex]m_1 = \frac{2 - (-1)}{5 - (-3)} = \frac{3}{8}[/tex]
The tangent of 109 degrees is [tex]\tan{109^{\circ}} = -\frac{29}{10}[/tex]Thus, the slope of line m is found solving the following equation:[tex]\tan{109^{\circ}} = \frac{m_2 - m_1}{1 + m_1m_2}[/tex]
[tex]-\frac{29}{10} = \frac{m_2 - \frac{3}{8}}{1 + \frac{3}{8}m_2}[/tex]
[tex]m_2 - \frac{3}{8} = -\frac{29}{10} - \frac{87}{80}m_2[/tex]
[tex]m_2 + \frac{87}{80}m_2 = -\frac{29}{10} + \frac{3}{8}[/tex]
[tex]\frac{167m_2}{80} = \frac{-202}{80}[/tex]
[tex]m_2 = -\frac{202}{167}[/tex]
Thus:
[tex]y = -\frac{202}{167}x + b[/tex]
It goes through point (-2,6), that is, when [tex]x = -2, y = 6[/tex], and this is used to find b.
[tex]y = -\frac{202}{167}x + b[/tex]
[tex]6 = -\frac{202}{167}(-2) + b[/tex]
[tex]b = 6 - \frac{404}{167}[/tex]
[tex]b = \frac{6(167)-404}{167}[/tex]
[tex]b = \frac{598}{167}[/tex]
Thus. the equation of line k, in slope-intercept formula, is:
[tex]y = -\frac{202}{167}x + \frac{598}{167}[/tex]
Item b:
Lines j and k intersect at an angle of 90º, thus they are perpendicular, which means that the multiplication of their slopes is -1.Thus, the slope of line j is:
[tex]-\frac{202}{167}m = -1[/tex]
[tex]m = \frac{167}{202}[/tex]
Then
[tex]y = \frac{167}{202}x + b[/tex]
Also goes through point (-2,6), thus:
[tex]6 = \frac{167}{202}(-2) + b[/tex]
[tex]b = \frac{(2)167 + 202(6)}{202}[/tex]
[tex]b = \frac{1546}{202}[/tex]
The equation of line j is:
[tex]y = \frac{167}{202}x + \frac{1546}{202}[/tex]

solve the following eqation: -8.2 + t/-2 = 1.7
Answers
Answer:
t = -19.8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
[tex]-8.2 + \frac{t}{-2} = 1.7[/tex] [tex]-8.2 - \frac{1}{2}t = 1.7[/tex] [tex]-\frac{1}{2}t - 8.2 = 1.7[/tex]Step 2: Add 8.2 to both sides.
[tex]-\frac{1}{2}t - 8.2 + 8.2 = 1.7 + 8.2[/tex] [tex]-\frac{1}{2}t = 9.9[/tex]Step 3: Multiply both sides by -2.

SHOW ALL WORK : A metal bar has a length of 5.0 cm, a width of 3.0 cm, and a height of 1.0 cm. What volume of water, measured in deciliters, would this bar displace?
Answers
9514 1404 393
Answer:
0.15 dL
Step-by-step explanation:
The volume of the bar is ...
V = LWH
V = (5 cm)(3 cm)(1 cm) = 15 cm³
1 dL = 100 cm³, so this volume is ...
(15 cm³)(1 dL)/(100 cm³) = 0.15 dL
The bar will displace 0.15 deciliters.

5x - 4y = 19
x + 2y = 8
Answers
Answer:
x= 5 and y = 1.5
Step-by-step explanation:
5x -4y = 19
x + 2y = 8
let x = 8 - 2y...
5x - 4y = 19.......x = 8 -2y
5(8-2y) - 4y = 19
40 - 10y -4y= 19
40-14y = 19
-14y = 19-40
-14y = -21
y = 1.5
x = 8 - 2(1.5)
x = 8 - 3
x = 5
Thus, x is 5 and y is 1.5

A function is a relation in which no two ordered pairs have the same first component and different second components.
We need to ask ourselves, does every first element (or input) correspond with EXACTLY ONE second element (or output)?
In this case, the answer is no. The input value of 1 goes with two output values, -1 and -5. The same goes with the input value of 2, which also goes with two output values: -2 and -4.
It only takes one input value to associate with more than one output value to be invalid as a function.
I also did the Vertical Line Test to show why Option 2 is not a function. The Vertical Line Test allows us to know whether or not a graph is actually a function. If a vertical line intersects the graph in all places at exactly one point, then the relation is a function.
However, the graph shows that the two vertical lines crossed the graphed twice (there are 2 points in each line). The graphed points failed the vertical line test. Therefore, Option 2 is NOT a function.

In ΔQRS, q = 9.4 cm, r = 8 cm and ∠S=151°. Find ∠Q, to the nearest 10th of a degree.
Answers
9514 1404 393
Answer:
15.7°
Step-by-step explanation:
The law of cosines can be used to find side s:
s² = r² +q² -2rq·cos(S)
s² = 8² +9.4² -2(8)(9.4)·cos(151°) ≈ 283.903
s ≈ 16.849
Then the law of sines can be used to find angle Q.
sin(Q)/q = sin(S)/s
sin(Q) = (q/s)sin(S)
Q = arcsin(q/s·sin(S)) = arcsin(9.4/16.849·sin(151°)) ≈ 15.692°
Angle Q is about 15.7°.
