Answer:
m = - 2 , c = 6
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 1, 8 ) and (x₂, y₂ ) = (3, 0 )
m = [tex]\frac{0-8}{3-(-1)}[/tex] = [tex]\frac{-8}{3+1}[/tex] = [tex]\frac{-8}{4}[/tex] = - 2 , then
y = - 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
using (3, 0 )
0 = - 6 + c ⇒ c = 0 + 6 = 6

Part (a)
x = number of adults
y = number of students
5x = amount all of the adults paid ($5 each)
2y = amount the students paid ($2 each)
5x+2y = total amount of money for adults and students combined
The total amount (5x+2y) must be more than $150
So we end up with 5x+2y > 150 as the inequality.
This inequality involves the boundary line 5x+2y = 150 which goes through the y and x intercepts of (0,75) and (30,0) respectively. We use a dashed line for the boundary to mean that points on the boundary are not included as solution points.
We shade above the dashed boundary line to finish off the graph.
Refer to figure (a) shown below.
========================================================
Part (b)
x = number of adults
y = number of students
x+y = total number of people
120 seats is the max capacity so x+y cannot exceed this value.
x+y = 120 or x+y < 120
Or in short x+y ≤ 120 is the inequality
This involves the boundary line x+y = 120 which goes through the y and x intercepts of (0,120) and (120,0). We shade below the solid boundary line.
Refer to figure (b) shown below.
========================================================
Part (c)
Now imagine we overlapped the blue region from part (a) and the red region from part (b)
We'll get the purple region shown in figure (c). At this point, I'm only considering cases when x ≥ 0 and when y ≥ 0. It's not possible to have a negative number of people, so that's why we focus on the upper right quadrant of the xy grid.
This purple region consists of all (x,y) points that make ALL of the inequalities to be true. Exclude any points on the dashed boundary.
For example, if we picked the point (x,y) = (50,40) then this point is in the purple region. We can confirm its a solution by checking each inequality.
5x+2y > 150
5*50+2*40 > 150
250+80 > 150
330 > 150 .... which is true
and,
x+y ≤ 120
50+40 ≤ 120
90 ≤ 120 ... which is also true
Furthermore, both x and y are nonnegative making x ≥ 0 and y ≥ 0 to be true as well. Every inequality mentioned is true for (x,y) = (50,40) to fully confirm the solution point. There are other possible solutions such as (40,60) and (80,20) which I'll let you verify.
If we stick to the (50,40) from earlier, then this means 50 adults and 40 students went to the concert.

Dana is given the total surface area of a rectangular pyramid. She is asked for the lateral surface area. Describe how Dana can use the given information to determine the lateral surface area.
To get the lateral surface area, dana will subtract the two base area from the total surface area.
Total surface area of rectangular prism
The total surface area of a rectangular prism is the sum of the areas of all of the faces or surfaces that enclose the solid. Therefore,
2lw + 2wh + 2lhwhere
l = length
w = width
h = height
Lateral surface area of a rectangular prismThe lateral surface area of a rectangular prism is the surface area of the solid without the bases.
Therefore,
LA = 2 ( l + w ) hTotal surface area = Lateral surface area + 2 (Base Area)
Total surface area = 2 (l + w) h + 2 (l x w) = 2lh + 2wh + 2lw
Therefore,
Lateral surface area = Total surface area - 2 (Base Area)
To get the lateral surface area, dana will subtract the two base area from the total surface area.

So, what you need to do here is to first plot all the points on the coordinate plane. When you plot all the points, and connect them all together, you should be able to see a shape. When I plotted all your points, I got a parallelogram or a rectangle, which is most likely the correct answer here because it is more specific than saying a parallelogram. A parallelogram can be a square, rhombus, or any other shape that fits the characteristics of one, so saying "rectangle" is better.

Step-by-step explanation:
We can solve this question by using the method of finding the square root.
The given equation is:
[tex]8x ^ { 2 } -3=2[/tex]
Add 3 to both the sides of the equation.
[tex]8x^{2}=2+3[/tex]
Now, add 2 & 3 to get 5.
[tex]8x^{2}=5[/tex]
Dividing both the sides of the equation by 8, we get...
[tex]x^{2}=\frac{5}{8}[/tex]
Now, take the square root of both the sides of the equation...
[tex]x =\sqrt{ \frac{ 5 }{ 8 } } \\x = \frac{\sqrt{5}}{\sqrt{8}} \\[/tex]
Rationalize the denominator.
[tex]x = \frac{\sqrt{5}}{2\sqrt{2}} \\x = \frac{\sqrt{5}\sqrt{2}}{2\left(\sqrt{2}\right)^{2}} \\x = \frac{\sqrt{5}\sqrt{2}}{2\times 2} \\x = \frac{\sqrt{10}}{2\times 2} \\x = \boxed{ \frac{\sqrt{10}}{4} , - \frac{\sqrt{10}}{4} }[/tex]

Step-by-step explanation:
Hello!
A) How much did you save?
Let's see. In order to find the savings, we must subtract the new price from the original.
50,000 - 18,000 = 32,000You saved $32,000 (a pretty good deal!)
B) What fraction of the original price was this?
To find the fraction, we must divide the new price from the original.
18,000/50,0009,000/25,000 => SImplify9/25 => SimplifyIt's 9 twenty-fifths of the original price.
C) What fraction of the original price was this?

Answer:
LM = 22
Step-by-step explanation:
11(44) = (LM)^2
484 = (LM)^2
LM = √484 = 22
Answer:
LM = 22
Step-by-step explanation:
If a tangent segment and a secant segment are drawn from an exterior point to a circle, then the square of the measure of the tangent segment is equal to the product of the measures of the external secant segment and the secant segment.
So for this circle,
point of intersection = Mtangent segment = LMexternal secant segment = NMsecant segment = OMSo LM² = NM · OM
Given:
NM = 11OM = 44LM² = 11 · 44 = 484
⇒ LM = √484 = 22

A rectangle has an area of (x2 − 17x + 72) square units. Since the area of a rectangle is determined using the formula, A = lw, what could be the length and width of the rectangle?
length = (x − 8) units and width = (x − 9) units
length = (x + 9) units and width = (x + 8) units
length = (x − 6) units and width = (x − 12) units
length = (x + 12) units and width = (x + 6) units
Answer:
The results are the opposite sign of x1 and x2.
[tex]lenght \: = (x - 8) \: and \: width \: = (x - 9)[/tex]
Step-by-step explanation:
[tex] {x}^{2} - 17x + 72 = 0[/tex]
[tex]Δ = {(17)}^{2} - 4(1 \times 72)[/tex]
[tex]Δ = 289 - 288 = 1[/tex]
[tex]x1 \: and \: x2 = \frac{17± \sqrt{1}}{2} [/tex]
[tex]x1 = \frac{17 + 1}{2} = 9[/tex]
[tex]x2 = \frac{17 - 1}{2} = 8[/tex]

3.2 Factoring 4g2 - 5g - 6
The first term is, 4g2 its coefficient is 4 .
The middle term is, -5g its coefficient is -5 .
The last term, "the constant", is -6
Step-1 : Multiply the coefficient of the first term by the constant 4 • -6 = -24
Step-2 : Find two factors of -24 whose sum equals the coefficient of the middle term, which is -5 .
-24 + 1 = -23
-12 + 2 = -10
