Answer:
The correct statements are (a), (c) and (d).
Step-by-step explanation:
The information provided is:
Rock the House Digital Designs charges $500.00 for the initial consultation with the Nelsons plus $50.00 for every additional hour of work for the house plans.Elegant Home Architects charge $75.00 per hour for the house plans.The variable h represent the number of hours for which Mr. and Mrs. Nelson hire the design firm.The total charge for Elegance Home Architects, if the Nelsons choose them will be:
Total for Elegance = 75 × h = 75h.
Suppose the Nelsons hire the design firm for 15 hours.
Total for Elegance = 75 × h = 75 × 15 = $1,125
Total for Rock = 500 + (50 × h) = 500 + (50 × 15) = $1,250
So, the Elegance Home Architects will be cheaper.
Suppose the Nelsons hire the design firm for 25 hours.
Total for Elegance = 75 × h = 75 × 25 = $1,875
Total for Rock = 500 + (50 × h) = 500 + (50 × 25) = $1,750
So, the Rock the House Digital Designs will be cheaper.
Thus, the correct statements are (a), (c) and (d).

What is the degree of
5x^2 -4x+2x^3
Answer:
This is a third-degree trinomial.
Step-by-step explanation:
To find the degree of a polynomial, simply look at the term with the highest power. In the case of this polynomial, the term with the highest power is 2x^3 which is a third power. Hence, this is a 3rd degree trinomial.

The solution of the expression are,
⇒ (4x + 1) (2x² - 5)
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ 8x³ + 2x² - 20x - 5
Now, We can simplify as;
⇒ 8x³ + 2x² - 20x - 5
⇒ (8x³ + 2x² ) + (- 20x - 5)
⇒ 2x² (4x + 1) - 5 (4x + 1)
⇒ (4x + 1) (2x² - 5)
Thus, The solution of the expression are,
⇒ (4x + 1) (2x² - 5)

use the graph to determine the domain and range of the relation and state whether the relation is a function
Answer:
the domain is {0, 1, 2, 3, 4... to positive infinity}
The range is {-1, -3, 0, -4 and so on}
this is not a function
Step-by-step explanation:
domain is a set of all x values, so just write the x values based on the graph
range is a set of all y values, so just write y values based on the graph
not function because it doesnt satisfy with the vertical line test.

Answer:
Option (C)
Step-by-step explanation:
x and y are two rational numbers.
Two inequalities which define these numbers are,
x + y < 5 ------(1)
3 < x < 5 -------(2)
In this question we will substitute the values of y given in the options in the inequality (1) to get the value of x. If the value of x satisfies the inequality (2), it will be the answer.
Option (A). y = [tex]\frac{8}{3}[/tex]
From inequality (1),
[tex]x+\frac{8}{3}<5[/tex]
[tex]x<5-\frac{8}{3}[/tex]
x < [tex]\frac{7}{3}[/tex]
x < 2.33
But 3 < x < 5, therefore, y = [tex]\frac{8}{3}[/tex] is not the answer.
Option (B). y = 2
x + 2 < 5
x < 3
But x is greater than 3. Therefore, Option (B) will not be the answer.
Option (C). y = 0
x + 0 < 5
x < 5
Inequality (2) states the same thing.
Therefore, Option (C) will be the answer.
Option (D). y = 3
x + 3 < 5
x < 5 - 3
x < 2
But x > 3, therefore, Option (D) will not be the answer.
Answer:
C is correct because if x is less than 5 and greater than 3 than is would most likely be 4 and 4 plus 0 equals 4 the problem says x plus y should be less than 5 and 4 plus 0 is less than 5
Step-by-step explanation:
Long answer short the answer is c

I need help with this Operation, 5-(1-5÷(-5)(5+1))? Please help me, I don't know what to do.
Answer:
-2
Step-by-step explanation:
5-(1-5÷(-5)(5+1))
Work the parentheses from the inside out
5-(1-5÷(-5)*6)
Them the Work inside the last parentheses and multiply and divide from left to right
5-(1-5÷(-5)*6)
5 divided by -5 = -1
5-(1-(-1))*6)
-1 * 6 = -6

9 9
Answer:
2 2/3 or 24/9
Step-by-step explanation:
3 2/9 - 5/9 = 24/9 = 2 6/9
3*9+2 = 29/9
29/9 - 5/9 = 2 6/9
2 6/9 turns into 2 2/3
2 2/3 is equal to 24/9
Answer:
2 2/3
Step-by-step explanation:
What you do is make 3 2/9 into an improper fractions --> 9 * 3 + 2 = 29/9
29/9 - 5/9 = 24/9
So, now you're going to make 24/9 into a mixed number which is 2 6/9 --> 2 2/3

Answer:
36[tex]\sqrt{3}[/tex] + 72
Step-by-step explanation:
The length of the rectangle = diameter of 2 circles = 4 × 3 = 12 mm
The width of the rectangle = 2 radii + distance d between radii ( lower to upper )
Using the right triangle formed by joining the 3 centres with legs 3 and d and hypotenuse 6
Using Pythagoras' identity, then
d² + 3² = 6²
d² + 9 = 36 ( subtract 9 from both sides )
d² = 27 ( take the square root of both sides )
d = [tex]\sqrt{27}[/tex] = 3[tex]\sqrt{3}[/tex]
Thus width of rectangle = 3 + 3[tex]\sqrt{3}[/tex] + 3 = 6 + 3[tex]\sqrt{3}[/tex]
Hence
area = length × width
= 12 × (6 + 3[tex]\sqrt{3}[/tex] ) = 36[tex]\sqrt{3}[/tex] + 72 mm ²
36 [tex]\sqrt{3}[/tex]+ 72
The length of the rectangle = diameter of 2 circles = 4 × 3 = 12 mm
The width of the rectangle = 2 radii + distance d between radii ( lower to upper )
Using the right triangle formed by joining the 3 centres with legs 3 and d and hypotenuse 6
Using Pythagoras' identity, then
d² + 3² = 6²
d² + 9 = 36 ( subtract 9 from both sides )
d² = 27 ( take the square root of both sides )
d = = 3
Thus width of rectangle = 3 + 3 + 3 = 6 + 3
Hence
area = length × width
= 12 × (6 + 3 ) = 36 + 72 mm ²
if m<FHI=142, what are m<FHG and m<GHI
angle FHG = 42 degrees
angle GHI = 100 degrees
=========================================================
Explanation:
FHI is the largest angle. It is split into two pieces FHG and GHI which have measures of (3x+6) and (9x-8) degrees respectively.
Put another way, those two smaller angles (FHG and GHI) combine to form the larger angle (FHI)
This is the angle addition postulate.
------------------
(angle FHG) + (angle GHI) = angle FHI
(3x+6) + (9x-8) = 142
3x+6+9x-8 = 142
(3x+9x) + (6-8) = 142
12x - 2 = 142
12x-2+2 = 142+2 ... adding 2 to both sides
12x = 144
12x/12 = 144/12 .... dividing both sides by 12
x = 12
------------------
Use that x value to find the angles we're after
angle FHG = 3x+6 = 3*12+6 = 36+6 = 42
angle GHI = 9x-8 = 9*12-8 = 108-8 = 100
Note how
(angle FHG) + (angle GHI) = 42 + 100 = 142
which is the measure of angle FHI. This confirms the answers.

(1 + 4i)^2
Solve please?
Answer:
-15 + 8i
Step-by-step explanation:
(1 + 4i)²
(1 + 4i) (1 + 4i)
FOIL - first -- outer -- inner -- last
F -- 1 x 1 = 1
O -- 1 x 4i = 4i
I -- 4i x 1 = 4i
L -- 4i x 4i = 16i²
combine terms
1 + 4i + 4i + 16i²
simplify
1 + 8i + 16i²
(i² = -1)
simplify further
1 + 8i + (16)(-1)
1 + 8i - 16
-15 + 8i

Select the statement that is true about the temperatures -9°F and -7°F.
A
-7°F,< -9°F because -7°F is colder than -9°F.
B
-7°F > -9°F because -7°F is colder than -9°F.
C -7°F >-9°F because -7°F is warmer than -9°F.
D -7°F <-9°F because -7°F is warmer than -9°F.
Answer:
C. -7f > -9 because -7f is warmer than -9f
Step-by-step explanation:
Process of Elimination
You can rule out B and D because the answer contradicts itself.
Previous Knowledge
We know -7f is warmer than -9f because its closer to 0 so we can rule out A
Therefore through the process of elimination you can conclude the answer is C

What are the roots of the equation x ^2+ 6x + 8 = 0?
Hi there! :)
Answer:
[tex]\huge\boxed{x = -4, -2}[/tex]
x² + 6x + 8 = 0
Factor the equation by finding two numbers that sum up to 6 and multiply into 8:
4 + 2 = 6
4 ×2 = 8
Rewrite in factored form:
(x + 4) (x + 2) = 0
Find the roots using the Zero-Product Property:
x + 4 = 0
x = - 4
x + 2 = 0
x = -2.
Therefore, the roots of this equation are at x = -4 and -2.
what is the value of y in the equation 6.4x+2.8y=44.4,when x=3?
Answer:
y = 9
Step-by-step explanation:
6.4x + 2.8y = 44.4
6.4(3) + 2.8y = 44.4
19.2 + 2.8y = 44.4
2.8y = 25.2
y = 9

Option 3 is the correct answer.
here,
when we cube the sum of 5 and 3 times y^2 it looks like,
=[tex] {(5 + 3 {y}^{2}) }^{3} [/tex]
now, when we divide it by cube of the product of 4 and y we get,
