Answer:
-8.75
Step-by-step explanation:
Rational: a number that can be expressed as an integer or the quotient of an integer divided by a nonzero integer.
A rational number is a number that can be expressed as a fraction with an integer numerator and a positive integer denominator. Two different fractions may correspond to the same rational number. 1/2 = 2/4. Every whole number is a rational number. These can be written as N/1 = N, so they are rational numbers.
Using formula:
[tex]\to \bold{rational\ value =\frac{a+b}{2}}[/tex]
Given:
a=-8
b=-9
Calculating the rational number:
[tex]\to \bold{rational\ number=\frac{-8+(-9)}{2}}[/tex]
[tex]\bold{=\frac{-8-9}{2}}\\\\ \bold{=\frac{-17}{2}}\\\\ \bold{=- 8.5}\\\\[/tex]

1Determine the vertex of the quadratic function f(x) = (x - 3)^2 +7.
Please give detailed steps!! thank you
Answer:
vertex = (- 3, 7 )
Step-by-step explanation:
The equation of a parabola in vertex form is
f(x) = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
f(x) = (x - 3)² + 7 ← is in vertex form
with vertex = (3, 7 )

Write a formula for the number of subsets of any set; identify any symbols use
Mark brainliest!!!
Formula-
If a set has “n” elements, then the number of subset of the given set is 2n and the number of proper subsets of the given subset is given by 2n-1. Consider an example, If set A has the elements, A = {a, b}, then the proper subset of the given subset are { }, {a}, and {b}
Symbol that can be used-
The symbol "⊆" means "is a subset of". The symbol "⊂" means "is a proper subset of".
Hope it helps you... pls mark brainliest if it helped you.

Determine the answer to (-3)+(-5) and explain the step using a number line
Answer:
below
Step-by-step explanation:
When are adding a negative number, that means that you just subtracting a positive value.
-3 + (-5) -> -3 - 5
On a number line you would to put finger at the point -3 and move to the left 5 spaces since we are subtracting.

The school ask you to determine the number scale of the drawing if the map length
actual 20 m boundary measurCs 16 cm on the diawing.
(Remember that both units must be the same
9514 1404 393
Answer:
1/125
Step-by-step explanation:
The map scale is usually shown as the ratio of the map distance to real-world distance. Here, that is ...
16 cm : 20 m = 16 cm : 2000 cm = 16 : 2000 = 1 : 125
The map scale is 1/125.

15-(4m - 5) = 32 please help me
Answer:
m = -3
Step-by-step explanation:
15 - (4m - 5) = 32 (Given)
15 - 4m + 5 = 32 (Distributed)
20 - 4m = 32 (Added like terms)
20 - 4m - 20 = 32 - 20 (Subtract 20 on both sides)
-4m = 12 (Simplify)
-4m/-4 = 12/-4 (Divide -4 on both sides)
m = -3 (Simplify)

please help, i do not get this.
Answer:
k(x) = |x - 4| - 2
Step-by-step explanation:
So we know that k(x) is shifted 4 untis to the right and 2 units down. In an absolute value function, the value you move to the left will be positive and the value you move to the right will be negative. Since we are moving to the right, our value will be negative.
When you shift the function up or down, you will either subtract or add that value out side the absolute value. Since we are shifting down 2 units, that means we will be subtracting by 2.
Best of Luck!

[tex]\huge\boxed{\sf f(4x + 5) = 16x\² + 40x + 25}[/tex]
Step-by-step explanation:
Given that:
f(x) = x²
Put x = 4x + 5
f(4x + 5) = (4x + 5)²
f(4x + 5) = (4x + 5)(4x + 5)
f(4x + 5) = 4x(4x + 5) + 5(4x + 5)
f(4x + 5) = 16x² + 20x + 20x + 25
f(4x + 5) = 16x² + 40x + 25
