3(x + 6) – 2(x – 4) > 5(x + 2)
Answer:
4 >x
Step-by-step explanation:
3(x + 6) – 2(x – 4) > 5(x + 2)
Distribute
3x+18 -2x+8 > 5x+10
Combine like terms
x +26 > 5x+10
Subtract x from each side
x+26-x > 5x-x+10
26 > 4x+10
Subtract 10 from each side
26-10 >4x+10-10
16 >4x
Divide each side by 4
16/4 >4x/4
4 >x
Sarkis wants to draw a triangle with sides measuring 4 ft, 10 ft, and 16 ft. Which is true about Sarkis’s plan? Sarkis cannot draw a triangle with these side lengths. Sarkis can only draw one unique triangle with these side lengths. Sarkis can draw exactly two triangles with these side lengths. Sarkis can draw more than one triangle with these side lengths.
Answer:
SHE CANNOT pls mark brainleist
Step-by-step explanation:
If you use the Triangle Inequality Theorem, you will find that 4+10 equals 14, which is less than 16. It has to be greater than 16 to be a triangle.
Sarkis cannot draw a triangle with these side lengths. Therefore, option A is correct.
Given that, a triangle with sides measuring 4 ft, 10 ft, and 16 ft.
What are the conditions to construct a triangle?In the triangle, the sum of any two sides is always greater than the third side. The difference between any two sides of the triangle is always less than the third side.
Sarkis cannot draw a triangle with these side lengths. Therefore, option A is correct.

Write the quadratic function in the form f(x)=a(x-h)^2+k. Then, give the vertex of its graph. Finally, graph the function by plotting the vertex and four additional points, two on each side of the vertex. f(x)=-2x^2+16x-35
Answer:
[tex]f(x) = -2(x - 4)^2 -3[/tex]
Vertex = (4, -3)
Graph in the image attached, additional points:
(2, -11), (3, -5), (5, -5), (6, -11)
Step-by-step explanation:
The vertex of f(x) can be found using the formula:
[tex]x_{vertex} = -b/2a[/tex]
[tex]x_{vertex} = -16 / (-4)[/tex]
[tex]x_{vertex} = 4[/tex]
to find y_vertex, we use x_vertex in f(x):
[tex]f(x_{vertex}) = -2 * 4^2 + 16*4 - 35[/tex]
[tex]f(x_{vertex}) = -3[/tex]
So the vertex is (4, -3)
To write the function in the form [tex]f(x)=a(x-h)^2+k[/tex], we just need to calculate h = -b/2a and then find k:
[tex]h = -b/2a = -16/(-4) = 4[/tex]
[tex]f(x) = -2(x - 4)^2 + k = -2(x^2 - 8x + 16) + k = -2x^2 + 16x - 32 + k[/tex]
Comparing both forms of f(x), we have:
[tex]-32 + k = -35[/tex]
[tex]k = -3[/tex]
So we have:
[tex]f(x) = -2(x - 4)^2 -3[/tex]
Now let's find the four additional points.
Two points to the left: x = 3 and x = 2
[tex]f(3) = -2 * 3^2 + 16*3 - 35 = -5[/tex]
[tex]f(2) = -2 * 2^2 + 16*2 - 35 = -11[/tex]
Two points to the right: x = 5 and x = 6
[tex]f(5) = -2 * 5^2 + 16*5 - 35 = -5[/tex]
[tex]f(6) = -2 * 6^2 + 16*6 - 35 = -11[/tex]

Malik's arts and crafts shop has a bolt of crimson velvet 32 meters long. A customer came in during the morning and bought 120 centimeters of the velvet. Another customer bought an additional 14 meters during the afternoon. How much crimson velvet does Malik's shop have left? Write the answer in centimeters.
The length of crimson velvet bolt which Malik's shop has left is 1680 centimeters.
Recall :
1 meter = 100 centimeters
Original Length of Bolt = 32 meters = (32 × 100) = 3200 centimeters
Total length of bolt purchased :
Morning purchase = 120 centimeters
Additional purchase = 14 meters = (14 × 100) = 1400 centimeters
Total length purchased = (120 + 1400) = 1520 centimeters
The length of crimson velvet bolt left :
(Original length - total length purchased)
(3200 - 1520) centimeters = 1680 centimeters
Hence, Malik's shop has 1680 centimeters of Crimson velvet bolt left

In the Soft Boulder Cafe each table has 3 legs, each chair has 4 legs and all the customers and the three members of staff have two legs each. There are four chairs at each table. At a certain time, three-quarters of the chairs are occupied by customers and there are 206 legs altogether in the cafe. How many chairs does the cafe have?
Answer:
32 chairs
Step-by-step explanation:
In the soft Boulder cafe they a chairs , table and customers and the 3 members staffs.
Each Table = 3 legs
Each Chairs = 4 legs
Each customer = 2 legs
Each members of staffs = 2 legs
4 chairs goes with each table. This means 4 × 4 = 16 legs of chairs for each 3 legs of table.
At a certain time 3/4 of the chairs are occupied by customers. That is 3 out of 4 chairs are occupied plus 6 tables . Therefore,
3 + 16 + 6 = 25 legs of table
206 legs altogether - the 6 legs of the staff(3 staffs has 6 legs)= 200 legs
This means 200 legs = 8 tables. Therefore,
8 tables requires 32 chairs

Line CD passes through points C(3, -5) and D(6, 0) . what is the equation of the line CD in standard form?
Answer:
Option 2: 5x - 3y = 30
Step-by-step explanation:
Step 1: Find slope
(0-(-5))/(6-3) = 5/3
Step 2: Find b
y = 5/3x + b
0 = 5/3(6) + b
b = -10
Step 3: Write in slope-intercept form
y = 5/3x - 10
Step 4: Move x over
-5/3x + y = -10
Step 5: Multiply by -3 on both sides
5x - 3y = 30

Answer:
here they are.
Step-by-step explanation:
Ok so the mean is the average of all the data. So we add up all the numbers, then divide that by the quantity of numbers.
For week one, thats 48,52,52,53,60,63,65 which equals 393, then we divide that by 7, and get 56.142857142857, so we round that to 56.1
Week 2 is 54,55,56,59,60,62,63 which is 409 divided by 7, and thats 58.428571428571 rounded is 58.4
Next up is the MAD (mean absolute deviation) thats the average distance between each value and the mean.
Week 1 MAD: 5.5918367346939 5.5
Week 2 MAD: 2.9387755102041 2.9

Answer: [tex]\frac{2A}{h} = w[/tex]
Step-by-step explanation:
The formula for area of a triangle is [tex]A = wh\frac{1}{2}[/tex]
Now we have to isolate for w.
First multiply by the 2 which is the reciprocal of 1/2 to cancel it out.
[tex]2A = wh\\[/tex]
Now divide by h to isolate w.
[tex]\frac{2A}{h} = w[/tex]
