Answer:
Y=3/7x+8 and y=-7/3x-34/3(11 1/3)
Step-by-step explanation:
for the perpendicular line, the slope is the opposite inverse (3/7) and since 3/7×-7=-3, -3+8=5, hence, y=3/7x+8.
for the parallel line the slope is the same, and since -7/3×-7=49/3,
and 49/3-15/3(5)=34/3, the equation is y=-7/3-34/3
Evaluate the expression for x = 2 and y = 4. Enter your answer in the box.
16x0 + 2x2 • y –1
Given that,
The given expression is : [tex]16x^0+2x^2{\cdot}y^{-1}[/tex]
To find,
The value of the above expression when x = 2 and y = 4
Solution,
We have,
[tex]16x^0+2x^2{\cdot}y^{-1}[/tex]
Put x = 2 and y = 4 in the above expression.
[tex]16x^0+2x^2{\cdot}y^{-1}\\\\=16\times (2)^0+2(2)^2\times (4)^{-1}\\\\=16\times 1+2(2)^2\times\dfrac{1}{4}\\\\=16+2\\\\=18[/tex]
So, the value of the above expression is 18.

3n2 + 13n+4= 0
Solve equation by factoring
Answer:
n = -4, -1/3.
Step-by-step explanation:
3n^2 + 13n+4= 0
3n^2 + 12n + n + 4 = 0
3n(n + 4) + 1(n + 4) = 0
(3n + 1)(n + 4) = 0
n = -4, -1/3.

The equation c = 2.5t represents the cost, c, for t tickets to the school play. Does a value of 3.5 for t make sense in this situation? Explain your reasoning.
Answer:
No
Step-by-step explanation:
Number of tickets can only be represented by integer values. A value of 3.5 for t would imply you can purchase three and a half tickets, which isn't possible.

Find the volume of the cone.
Answer:
Step-by-step explanation:
volume=1/3 πr²h
=1/3×π×3²×4
=12π ft³
≈37.70 ft³
Here we have to calculate the volume of the cone which is provided in the figure.
As we know that volume of cone is calculated by the formula :
[tex]\orange{\boxed{\bf{V \: = \: \frac{1}{3} \: \pi \:r {}^{2}h }}} [/tex]Here,
r is radius h is height Value of π is 22/7We have :
Radius (r) is 3 ft. Height (h) is 4 ft.Putting the values in the formula :

Given:
Total number of students = 20
The marks of the students are 40, 22, 36, 27, 30, 12, 15, 20, 25, 31, 34, 36, 39, 41, 43, 48, 46, 36, 37 and 40.
To find:
The frequency distribution table with class size 10.
Solution:
We have, the marks of 20 students.
40, 22, 36, 27, 30, 12, 15, 20, 25, 31, 34, 36, 39, 41, 43, 48, 46, 36, 37, 40
Here,
Minimum value = 12
Maximum value = 48
We nee class intervals of size 10. So, the required class intervals are 10-20, 20-30, 30-40, 40-50. In these intervals, lower limit is excluded but the upper limit included.
The required frequency distribution table is
Class intervals Marks Frequency
10-20 12, 15 2
20-30 22, 27, 20, 25 4
30-40 36, 30, 31, 34, 36, 39, 36, 37 8
40-50 40, 41, 43, 48, 46, 40 6
Total 20
Therefore, the frequency distribution table is
Class intervals: 10-20 20-30 30-40 40-50 Total
Frequency : 2 4 8 6 20

A construction company is analyzing which of its older projects need renovation. Building B was built two years before building C. Building D was built two years before building B. The product of the building B’s age and building D’s age is at least 195. If x represents the age of building C, which inequality represents this situation?
Answer:
x²+6x +8 ≥ 195
Step-by-step explanation:
The age of C is represented by c= x .
Building B was built two years before building C.
Age of Building B b = x+ 2
Building D was built two years before building B
Age of Building d= x+4
The product of the building B’s age and building D’s age is at least 195.
b*d ≥ 195
≥ means product is greater than or equal to 195 at least 195
Putting the values of b and d
(x+ 2) (x+4) ≥ 195
It can be further solved
x²+6x +8 ≥ 195
Answer:
x^2+6x+8>195

What is an aquifer?
Why is gravity part of the water cycle ?
Answer:
An aquifer is an underground layer of water-bearing permeable rock, rock fractures or unconsolidated materials. It pulls precipitation down from clouds and pulls water downhill. Gravity also moves air and ocean water. Gravity pulls denser air and water downward, forcing less dense air and water to move upward.
Step-by-step explanation:

The image of F(-5,-9) after translating along <4, 6 > and then translating along < 3, 5> is? F’(?,?)
==============================================
Explanation:
The phrasing "translated along <4,6>" is another way of saying "shift 4 to the right, shift 6 up"
In general, "translated along <m,n>" is the same as writing [tex](x,y) \to (x+m, y+n)[/tex]. If m is positive, then we shift m units to the right. If m is negative, then we shift to the left. The same story happens with the n, but we focus on the y coordinate.
-------------
With all that in mind, starting at F(-5,-9) and translating along <4,6> has us arrive at (-1, -3). Add 4 to the x coordinate and add 6 to the y coordinate.
We can say
[tex](x,y) \to (x+4,y+6)\\\\(-5,-9) \to (-5+4,-9+6)\\\\(-5,-9) \to (-1,-3)\\\\[/tex]
Showing that (-5,-9) moves to (-1,-3)
This is after the first translation, but there's a second translation.
We'll apply the same idea, but different numbers this time
[tex](x,y) \to (x+3,y+5)\\\\(-1,-3) \to (-1+3,-3+5)\\\\(-1,-3) \to (2,2)\\\\[/tex]
So (-1,-3) moves to (2,2)
Overall we have
(-5,-9) move to (-1,-3) after the first translation(-1,-3) move to (2,2) after the second translationTherefore, the original point ends up at (2,2) which is the final answer
--------------
Extra info:
A nice shortcut is that the vectors <4,6> and <3,5> can be added to get <4+3,6+5> = <7,11>. So overall, we're shifting 7 units to the right and 11 units up when we combine the two translation vectors.

Answer:
f*g(x) = -25
Step-by-step explanation:
f*g(x) = f(x) * g(x) = x² * (3x + 14)
f*g(x) = (-5)² * (3*-5 +14) = 25 * (-1) = -25

write the equation -×+3y=6 in slope intercept form.
Answer:
y=1/3x + 2
Step-by-step explanation:
Since slope intercept form is y=, I first added x to each side to get x on the other side. Then I divided each side by 3 to get y, and ended up with y=1/3x+2 as my answer.

Step-by-step explanation:
Interior angles of a polygon = (sides - 2) × 180
Exterior angles are always 360
Please Mark as Brainliest if you found it helpful!
The measures of an exterior angle are 2520°, and an interior angle is 360° in the given regular polygon with 16 sides.
What is the interior Angle?An interior angle is defined as an angle produced on the inside of a polygon by extending the sides of the polygon.
Interior angles of a polygon = (sides - 2) × 180°
To determine the measures of an exterior angle and an interior angle given a regular polygon with 16 sides.
Interior angles of a polygon = (sides - 2) × 180°
In this case, the number of sides is 16
Interior angles of a polygon = (16 - 2) × 180
Interior angles of a polygon = (14) × 180
Interior angles of a polygon = 2520
And, Exterior angles are always 360° in the regular polygon.
Similarly, the other regular polygons :
A regular polygon with 24 sides: Int 3960, Ext 360
A regular polygon with 30 sides: Int 5040, Ext 360
A regular polygon with 14 sides: Int 2160, Ext 360
A regular polygon with 22 sides: Int 3600, Ext 360
A regular polygon with 40 sides: Int 6840, Ext 360
