when x = 3 and y = -6 , the value of the expression is *blank*
Below is the table of values of a function. Write the output when the input is n.
Answer:
when input = n, Output = 4n
Step-by-step explanation:
Output = k(input)
Where,
k = constant
Find k When output = 8 and input = 2
Output = k(input)
8 = k(2)
8 = 2k
k = 8/2
k = 4
Find k When output = 28 and input = 7
Output = k(input)
28 = k(7)
28 = 7k
k =28/7
k = 4
Find output when input = n
Output = k(input)
= 4(n)
= 4n
Output = 4n
when input = n, Output = 4n

Solve the equation x – 5 = 0.1(x + 5) for x
Answer:
Step-by-step explanation:
x - 5 = 0.1(x +5)
x - 5 = 0.1x + 5*0.1
x -5 = 0.1x + 0.5 {Add 5 to both sides}
x = 0.1x + 0.5 + 5
x = 0.1x + 5.5
x -0.1x = 5.5 {subtract 0.1x from both sides}
0.9x =5.5 {Divide both sides by 0.9}
x = 5.5/0.9
x = 55/9
x = 6 1/9
Answer:
x = ⁵⁵/₉ = 6¹/₉Step-by-step explanation:
x - 5 = 0.1(x + 5) {multiply both sides by 10}
10x - 50 = x + 5 {subtract x from both sides}
9x - 50 = 5 {add 50 to both sides}
9x = 55 {divide both sides by 9}
x = ⁵⁵/₉ = 6¹/₉
can someone help me with this please - can you also give a step by step not just an answer
Answer:
The way I was taught to do it is to change value into a total fraction, then multiple the numerators together, multiply the denominators together, and finally reduce as far as possible.
7/9 x 5 2/5 = 7/9 x 27/5 = 189/45 = 4 9/45 = 4 1/5
1 3/4 x 4 1/6 = 7/4 x 25/6 = 175/24 = 7 7/24
Estimate the square root of the following imperfect square:
7.
a. 2.2
b. 2.4
C. 2.6
d. 2.8
This problem is just try and error.
First we try number 2.5 since its the average of all the answers.
2.5^2=6.25
This is smaller than 7 so the answer is either 2.6 or 2.8
Now let's try 2.7
2.7^2=7.29
Which is bigger than 7 and that means the correct answer is 2.6 :)
A hemispherical tank is filled with water and has a diameter of 15 feet. If water weighs 62.4 pounds per cubic foot, what is the total weight of the water in a full tank, to the nearest pound?
Answer:
55135 lbs (rounded to the nearest pound)
Step-by-step explanation:
diameter of tank = 15 ft
Radius = 15/2 =7.5
volume of hemisphere = 2/3 ×π× 7.5³=883.5729
total weight of water = 62.4 × 883.57 = 55134.768
55134.768 rounded to the nearest pound is 55135 lb

Verify that the segment lengths form a triangle. Is the triangle acute, right, or obtuse?
Answer:
The lengths do form a triangle and it is a right triangle.
Step-by-step explanation:
Part I:
To find out if 3 segment lengths form a triangle, you must verify that the sum of the two SMALLER sides (6+8) is GREATER than the longest side (10). That is true for this case. We have a triangle
Part II:
To find out the type of triangle, we must incorporate the Pythagorean theorem:
If [tex]c^2 = a^2 + b^2\\[/tex] then it is a right triangle. Substitute the values. (c=10, b=8, 6=a)[tex]10^2 = 6^2 + 8^2\\100 = 100[/tex]Please help me I will give you the brain thing and extra points please.
Which side lengths represent the sides of a right triangle?
A)1, 1, 2
B)2, 3, 5
C)3, 4, 5
D)5, 11, 13

Above are two different models of the same triangle. If the area of the model on the left is 24 sq cm, what is the area of the model on the right?
The area of the model on the right = area of model on the left × 3² = 216 sq. cm.
What is a Model?A model represents a real object on a drawing paper.
Given that the model is triangular in shape, the model on the right is 3 times the model on the left.
Therefore, area of model on the left = area of model on the left × 3².
Area of model on the left = 24 × 9
Area of model on the left = 216 sq. cm.

Enter an expression equivalent to (3x^2+2y^2-3x)+(2x^2+y^2-2x)-(x^2+3y^2+x) using the fewest number of possible terms
Answer:
2x(2x - 3)
Step-by-step explanation:
Given:
(3x^2+2y^2-3x)+(2x^2+y^2-2x)-(x^2+3y^2+x)
Written as:
(3x² + 2y² - 3x) + (2x² + y² - 2x) - (x² + 3y² + x)
= 3x² + 2y² - 3x + 2x² + y² - 2x - x² - 3y² - x
Collect like terms
= 3x² + 2x² - x² + 2y² + y²- 3y² - 3x - 2x - x
= 4x² + 0 - 6x
= 4x² - 6x
= 2x(2x - 3)
