f (x) = -x² + 6x - 18
Find f (-3)
Answer:
-45Step-by-step explanation:
Given
f (x) = -x² + 6x - 18To find f (-3) substitute x with -3
f(-3) = -(-3)² + 6(-3) - 18 = - 9 - 18 - 18 = -45f(-3) = -45Step-by-step explanation:
[tex]f(x) = - {x}^{2} + 6x - 18 \\ f( - 3) = - {( - 3)}^{2} + 6( - 3) - 18 \\ = - 9 - 18 - 18 \\ = - 45[/tex]
-45 is the right answer.What property is represented?
40 + 0 = 40
• identity
• inverse
• associative
• commutative
Identity property!
Because the identity property for addition tells us that zero added to any number is the number itself. Zero is called the "additive identity." In this case, 0 is being added to 40.

The complete question is:
If x = 3 (y + w) -1 what is the value of w in terms of x and y?
A.) w = StartFraction x minus 3 y Over 3 EndFractionB.) w = StartFraction x minus 3 y + 1 Over 3 EndFractionC.) w = x minus 3 y + 1D.) w = StartFraction x + 1 Over 9 y EndFractionWe have an expression:
x = 3 (y + w) -1
To find the value of w in terms of x and y.
By using the distributive property:
x = 3y + 3w - 1
By arranging the equation:
3w = x - 3y + 1
Divide by 3 on both the side:
w = (x - 3y + 1)/3
Thus, the equation x = 3y + 3w - 1 can be written as in terms of x and y by making the subject w is w = (x - 3y + 1)/3 option (B) is correct.

A small airplane can hold 44 passengers.fifteen passengers board the plane a. Identify an inequality that represents the additional number of passengers,p, that can board the plane. •15+p<= 44•p—44<=15 • 15+p>=44•15+p<=44. Solve the inequality, the solution is: B. Which best explains whether or not 30 more passengers can board the plane. Please solve this
Answers:
Inequality is [tex]15 + p \le 44[/tex]
Choice A) 30 more passengers cannot board the plane. Only 29 more passengers can board the plane
===============================================
Explanation:
15 people are already on the plane.
p is a placeholder for a positive whole number representing the additional number of people that can get on the plane.
In total, the plane holds 15+p individuals.
This expression's largest possible value is 44. Think of it as the ceiling. In terms of math, we call it the maximum. Since at most 44 people can be on the plane, this means the inequality we'll set up is [tex]15+p \le 44[/tex]
This says "15+p is less than or equal to 44". It's the same as saying "15+p is 44 or smaller".
---------------------------
To isolate p, we subtract 15 from both sides
Doing so leads to...
[tex]15+p \le 44\\\\15+p-15 \le 44-15\\\\p \le 29[/tex]
We can see that the largest p can get is 29, meaning that at most 29 more people can board the plane. There's no way that 30 people can board. That unfortunate 30-29 = 1 person must wait for another plane.
This all shows why choice A is the answer.
----------------------------
As a way to check the answer, we can note how p = 29 leads to 15+p = 15+29 = 44. We've filled the plane to full capacity.
If p = 30, then 15+p = 15+30 = 45, and we've gone 1 seat overboard.
How to solve using Substitution or Elimination??? Help!!
y=3x-1
y=2x+2
Answer:
Step-by-step explanation:
Since both equations equals y, then both equations equal each other.
3x - 1 = 2x + 2
Subtract 2x from both sides
x - 1 = 2
Add 1 to both sides
x = 3
Plug x = 3 into one equation(doesn't matter which)
y = 3x - 1
y = 3(3) - 1
y = 9 - 1
y = 8
Answer:
[tex]x=3[/tex]
[tex]y=8[/tex]
Step-by-step explanation:
From these two equations, we can substitute the first equation into the second equation (or the other way round). This gives us:
[tex]3x-1=2x+2[/tex]
[tex]3x-2x=2+1[/tex] (minus [tex]2x[/tex] and add [tex]1[/tex] on both sides)
[tex]x=3[/tex]
To solve for [tex]y[/tex], we can use substitution again:
[tex]y = 3(3)-1[/tex] (using the first equation given)
[tex]y=8[/tex]
Hope this helps :)

What type of number is v64?
Choose all answers that apply:
A)Whole number
B) Integer
c Rational d) irrational
The correct answers are A) Whole number, B) Integer, and C) Rational.
The number √64 is equal to 8. It satisfies the condition √64 = 8 because 8 multiplied by itself (8 x 8) equals 64.
Based on the options provided, the correct answers are:
A) Whole number: Yes, √64 is a whole number. Whole numbers are non-negative integers, and 8 is a non-negative integer.
B) Integer: Yes, √64 is an integer. Integers are numbers that can be positive, negative, or zero without any fractional or decimal parts. In this case, 8 is a positive integer.
C) Rational: Yes, √64 is a rational number. Rational numbers can be expressed as a fraction p/q, where p and q are integers, and q is not zero. The square root of 64 can be written as 8/1, which is a fraction where both the numerator and denominator are integers.
D) Irrational: No, √64 is not an irrational number. Irrational numbers cannot be expressed as fractions and have an infinite non-repeating decimal expansion. However, √64 is a terminating decimal, as it equals 8, which means it is not an irrational number.
Therefore, the correct answers are A) Whole number, B) Integer, and C) Rational.

In the figure below, what is the value of x
Answer:
x = 49°
Step-by-step explanation:
Angles in a Triangle
The sum of the internal angles in any triangle adds up to 180°.
The figure shows a triangle that includes two angles with the same tick mark. This means they are congruent, i.e. they measure the same.
The larger triangle has three defined angles: 43°, 39°, and 2x. Since the sum of them is 180°:
43° + 39° + 2x = 180°
Operating:
82° + 2x = 180°
Subtracting 82°:
2x = 180° - 82° = 98°
x = 98°/2 = 49°
x = 49°

A furniture manufacturer produces chairs and sofas. Each chair requires 10 yards of fabric, and each sofa requires 20 yards of fabric. The manufacturer has 300 yards of fabric available. To fulfill orders, the number of sofas must be at least twice the number of chairs. The manufacturer earns a profit of $50 on each chair and $80 on each sofa. Let x represent the number of chairs and y represent the number of sofas. Choose the function that represents the manufacturer's profit, P.
Given:
Fabric required for each chair = 10 yards
Fabric required for each sofa = 20 yards.
Total available fabric = 300 yards.
The number of sofas must be at least twice the number of chairs.
Profit on each chair = $50
Profit on each sofa = $80.
To find:
The function that represents the manufacturer's profit, P.
Solution:
Let P represents the manufacturer's profit, x represent the number of chairs and y represent the number of sofas.
Profit on 1 chair = $50
Profit on x chairs = $50x
Profit on 1 sofa = $80
Profit on y sofas = $80y
Total profit = Profit on x chairs + Profit on y sofas
[tex]P=50x+80y[/tex]
Therefore, the required profit function is [tex]P=50x+80y[/tex].

Select all the numbers that show 4% as an equivalent fraction, decimal, or percent.
[] 0.04
[] 40%
[] 10
[] 4
[] 100
[] 0.4
Answer:
Step-by-step explanation:
0.04
All the numbers that show 4% as an equivalent fraction, decimal or percent from the listed options are:
In fraction: [tex]4\% = \dfrac{4}{100}[/tex]In decimal: [tex]4\% = 0.04[/tex]How to convert percent to fraction and decimal?Percent counts the number compared to 100.
So, if we have a%, that means for each 100, there are 'a' parts. If we divide each of them with 100, we get:
For each 1, there are a/100 parts.
Thus, 50% = 50/100 = 0.50 (in decimal)
For this case, the percent we have is 4%
That shows that for each 100 items, we have 4 of them. This can be written in fraction as 4/100
Solving this division, we get the result in decimal as 0.04
Thus, all the numbers that show 4% as an equivalent fraction, decimal or percent from the listed options are:
