Answers
The unknown number will be 31, if -16 is added to it and the sum is doubled, the result is 1 less than the number.
Let the unkown number be x.
Now according to the given question.
If -16 is added to the unknown number and the sum is doubled, the result is 1 less than the number.
⇒ (x + (-16))2 = x - 1
⇒ 2x - 32 = x - 1
⇒ 2x - x = -1 + 32
⇒ x = 31
Hence, the unknown number will be 31, if if -16 is added to it and the sum is doubled, the result is 1 less than the number.

Answers
Using translation concepts, the point that lies on the new graph is given by: (-1, -4).
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
The equivalent translation to an horizontal shrink by a factor of a a function f(x) is given by:
f(ax).
Hence, in this problem, for the horizontal shrink by a factor of 4, the function will be given by:
g(x) = f(4x) = 4x.
Then when x = -1, the output is given by:
g(-1) = 4(-1) = -4.

Answers
The length of the diagonal of the TV is 50 inches
Given that the TV is 30 inches tall and 40 inches wide.
So length of the TV, l = 30 inches
and Width of the TV = 40 inches
The angle between the length and width of the TV is right angle. So we can use Pythagoras Law here.
That is, square of the hypotenuse is equal to the sum of the squares of the base and altitude of the right triangle.
i.e., If 'd' is the diagonal of the TV, then,
[tex]d^2 = l^2 +b^2 = 30^2+40^2 = 2500[/tex]

Answers
The value of a is 3.
The value of b is -14.
What is Coordinates?
A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.
Given that;
The function of the graph is,
y = 2x² + ax + b
The graph intersects the x-axis at the points (-7/2, 0) and (2, 0).
Now,
Since, The graph intersects the x-axis at the points (-7/2, 0) and (2, 0).
Hence, The points must satisfy the graph of the function.
So, Points (-7/2, 0) and (2, 0) are satisfy the function y = 2x² + ax + b.
When point (-7/2, 0) satisfy the function y = 2x² + ax + b
Then,
0 = 2 × (-7/2)² + a × (-7/2) + b
0 = 49/2 - 7a/2 + b
7a/2 - b = 49/2 .... (i)
And, When point (2, 0) satisfy the function y = 2x² + ax + b
Then,
0 = 2 × (2)² + a×2 + b
2a + b = -8 .... (ii)
Add equation (i) and (ii) we get;
7a/2 - b + 2a - b = 49/2 + (-8)
11a/2 = 33/2
11a = 33
a = 3
And, 2a + b = -8
2 × 3 + b = -8
b = -8 - 6
b = -14
Hence, The value of a is 3.
The value of b is -14.

3(3x+5)-4x+5= -15 solve for x
Answers
Answer:
x = -7
Step-by-step explanation:
Solve for x:
5 - 4 x + 3 (3 x + 5) = -15
3 (3 x + 5) = 9 x + 15:
(9 x + 15) - 4 x + 5 = -15
Grouping like terms, 9 x - 4 x + 5 + 15 = (-4 x + 9 x) + (5 + 15):
((-4 x + 9 x) + (5 + 15)) = -15
9 x - 4 x = 5 x:
5 x + (5 + 15) = -15
5 + 15 = 20:
5 x + 20 = -15
Subtract 20 from both sides:
5 x + (20 - 20) = -20 - 15
20 - 20 = 0:
5 x = -20 - 15
-20 - 15 = -35:
5 x = -35
Divide both sides of 5 x = -35 by 5:
(5 x)/5 = (-35)/5
5/5 = 1:
x = (-35)/5
The gcd of -35 and 5 is 5, so (-35)/5 = (5 (-7))/(5×1) = 5/5×-7 = -7:
Answer: x = -7
Answer:
x = -7
