D.If the Johnson family hires the design firm for 15 hours, then Elegance Home Architects will be cheaper.
E.If the Johnson family hires the design firm for 40 hours, then Rock the House Digital Designs will be cheaper.
Step-by-step explanation:
Which of the following statements are true? Select all that apply.
A.The expression 50ℎ represents the total charge for Rock the House Digital Designs.
B.The expression 75ℎ represents the total charge for Elegance Home Architects.
C.The cost for using Rock the House Digital Designs for an initial consultation only is $550.
D.If the Johnson family hires the design firm for 15 hours, then Elegance Home Architects will be cheaper.
E.If the Johnson family hires the design firm for 40 hours, then Rock the House Digital Designs will be cheaper.
Answer:
Rock the House Digital Designs charges $500.00 for the initial consultation with the Johnson family, plus $50.00 for every additional hour of work for the house plans. If they are hired for h hours, the total charge for Rock the House Digital Designs would be:
Total charge for Rock the House Digital Designs = 500 + 50h
Elegant Home Architects charge $75.00 per hour for the house plans, if they work for h hours, the total charge would be:
Total charge for Elegance Home Architects = 75h
A) Option A is not correct since the total charge for Rock the House Digital Designs is 500 + 50h
B) Option B is correct because the total charge for Elegance Home Architects = 75h
C) Option C is not correct, For an initial consultation, the cost for using Rock the House Digital Designs is $500
D) For a period of 15 hours:
Total charge for Rock the House Digital Designs = 500 + 50h = 500 + 50(15) = $1250
Total charge for Elegance Home Architects = 75h = 75(15) = $1125
Option D is correct because Elegance home architect would be cheaper
E) For a period of 40 hours:
Total charge for Rock the House Digital Designs = 500 + 50h = 500 + 50(40) = $2500
Total charge for Elegance Home Architects = 75h = 75(40) = $3000
Option D is correct because Rock the House Digital Designs would be cheaper

Answer:
x = 8
Step-by-step explanation:
11x - 34 and 7x - 2 are vertical angles and congruent, thus
11x - 34 = 7x - 2 ( subtract 7x from both sides )
4x - 34 = - 2 ( add 34 to both sides )
4x = 32 ( divide both sides by 4 )
x = 8
-----------------------
11x - 34 = 11(8) - 34 = 88 - 34 = 54
18y and 11x - 34 are adjacent angles and supplementary , thus
18y + 54 = 180 ( subtract 54 from both sides )
18y = 126 ( divide both sides by 18 )
y = 7

So answer is C.
Hmm first I'll check the slanted line cutting 2nd quardrant..
some points on this line are (-3,0),(0,3),(2,5),(3,6),etc.
Testing (-3,0)=(x,y):
y=-3+3=0 (true)..comparable with y=x+3
Testing (2,5)=(x,y):
y=2+3=5 (true)..comparable with y=x+3
Since this line bounds the value within some limits less than or equal to x+3(see graph you can see it clearly)...so it can be represented by y<=x+3.
Similarly for next line cutting 1st and 4th quardrant,
Points: (0,-4),(1,-1),(2,2),etc..
Testing (0,-4)=(x,y):
y=3*0-4=-4(true)...comparable with y=3x-4
Testing (1,-1)=(x,y):
y=3*1-4=-1(true)...comparable with y=3x-4
This line bounds within the region y>3x-4
NOTE:
1)If the region is bounded by solid line(line without dot) then you write inequality as y<=something or y>= something.
2)If the region is bounded by dotted line(line withdot) then you write inequality as y<something or y> something.
Hope this helps!

Answer: 5/7
Step-by-step explanation:
To simplify 20/28 using the greatest common factor, we need to find the largest number that divides evenly into both 20 and 28. The greatest common factor of 20 and 28 is 4. Dividing both numbers by 4, we get 5/7. Therefore, 20/28 simplifies to 5/7.

Answer:
Part A y = 15(1 + 0.4)^x.
Part B 434 after 10 days.
Step-by-step explanation:
Part A.
21 = 15 ( 1 + r)^1
15 + 15r = 21
15r = 6
r = 6/15 = 0.4
So the equation is
y = 15(1 + 0.4)^x.
Part B.
So after 10 days x = 10
y = 15(1 + 0.4)^10
y = 434 to the nearest whole number.
Answer:
y = 434 to the nearest whole number.
