Step-by-step explanation:
(m - 2)x + y = 2
y = -(m - 2)x + 2
8 = -(m - 2)(2) + 2
6 = -(m - 2)(2)
3 = -(m - 2)
-3 = m - 2
-1 = m
mx + 2y = k
2y = -mx + k
[tex]y = - \frac{1}{2} mx + \frac{k}{2} \\ y = \frac{1}{2} x + \frac{k}{2} \\ 8 = \frac{1}{2} (2) + \frac{k}{2} \\ 7 = \frac{k}{2} \\ 14 = k[/tex]

Step-by-step explanation:
[tex] \frac{( {x}^{5}y {z}^{4} )^{3} }{ {x}^{3} yz} = {x}^{a} {y}^{b} {z}^{c} \\ \\ \frac{ {x}^{5 \times 3}y^{3} {z}^{4 \times 3} }{ {x}^{3} yz} = {x}^{a} {y}^{b} {z}^{c} \\ \\ \frac{ {x}^{15}y^{3} {z}^{12} }{ {x}^{3} yz} = {x}^{a} {y}^{b} {z}^{c} \\ \\ {x}^{15 - 3} {y}^{3 - 1} {z}^{12 - 1} = {x}^{a} {y}^{b} {z}^{c} \\ \\ {x}^{12} {y}^{2} {z}^{11} = {x}^{a} {y}^{b} {z}^{c} \\ \\ equating \: like \: terms \: from \: both \: sides \\ \\ {x}^{12} = {x}^{a} \: \implies \: a = \boxed{ 12}\\ \\ {y}^{2} = {y}^{b} \: \implies \: b = \boxed{ 2} \\ \\ {z}^{11} = {z}^{c} \: \implies \: c = \boxed{ 11}[/tex]
4. Bikes A and B are traveling on perpendicular roads. At the same time, bike A is
leaving the intersection at a rate of 2 feet per second and bike B is leaving the
intersection at 3 feet per second. How fast is the distance, in feet per second between
them changing after 5 seconds?
Answer:
[tex]\sqrt{13}[/tex]
The rate of change of distance between two cars at the given time is required.
The required rate of change is [tex]\sqrt{13}[/tex] feet/s
Rate of changea = Distance covered in 5 s by bike A = [tex]2\times 5=10\ \text{feet}[/tex]
b = Distance covered in 5 s by bike B = [tex]3\times 5=15\ \text{feet}[/tex]
c = Distance between A and B in 5 s = [tex]\sqrt{10^2+15^2}=5\sqrt{13}\ \text{feet}[/tex]
Applying Pythagoras theorem
[tex]a^2+b^2=c^2[/tex]
Differentiating with respect to time
[tex]2a\dfrac{da}{dt}+2b\dfrac{db}{dt}=2c\dfrac{dc}{dt}\\\Rightarrow \dfrac{dc}{dt}=\dfrac{a\dfrac{da}{dt}+b\dfrac{db}{dt}}{c}\\\Rightarrow \dfrac{dc}{dt}=\dfrac{10\times 2+15\times 3}{5\sqrt{13}}\\\Rightarrow \dfrac{dc}{dt}=\sqrt{13}\ \text{feet/s}[/tex]

A florist is looking to make arrangements of red and white roses for bouquets. The flowers are priced so that she makes a profit of $1.25 per red rose and $1.00 per white rose in a bouquet. Her goal is to make at least $1000 from sales of these bouquets. Based on her available time and supplies of red and white roses, she is considering two possibilities: 130 bouquets of 4 red roses and 3 white roses each or 110 bouquets of 3 red roses and 5 white roses each. Will either of these possibilities turn the profit the florist is seeking?
Answer:
Option 1Step-by-step explanation:
Option 1
130 bouquets of 4 red roses and 3 white roses each. Profit is:
130*(4*$1.25 + 3*$1) = $1040 > $1000Option 2
110 bouquets of 3 red roses and 5 white roses each. Profit is:
110*(3*$1.25 + 5*$1) = $962.50 < $1000As we see option 1 is bringing target profit so should be her choice
Answer:
30 bouquets of 4 red roses and 3 white roses each.

Mr. Gregson packs ornaments into boxes. Each box holds eight ornaments. Which representation displays the relationship between x, the number of boxes packed, and y, the number of ornaments packed?
Answer:
y = 8x
Step-by-step explanation:
Given that :
Ornanment are packed in boxes
Number of ornament per box = 8
x = number of boxes packed
y = Number of ornaments
Number of Ornanments packed = (Number ornaments per box * number of boxes packed
y = 8 * x
y = 8x

Please help. I need to refresh my mind of this problem and a few more if you don't mind
Answer: c
Step-by-step explanation:
look at the equation and insert the value of X from the table into the equation and figure out which one will give you the same sum for the values. for example f(x) = 3(-2)-1
this answer gives you f(x)= -6 -1 which will give u a sum of -7
another one : f(x)= 3(0)-1
3 multiplied by 0 gives you 0 therefore you are left with -1
by doing this you prove that this equation works with ur x values and gives you the same sum you have for f(x)

The equation of the line is( )
Answer:
