4x – 4y = 24
y= 7x + 6
A) (-2, 8)
C) (-8,8)
B) (-2, -8)
D) (-8, -8)
Answer:
B) (-2, -8) is the solution for 4x - 4y = 24 and y = 7x + 6
Step-by-step explanation:
4x - 4y = 24
4(-2) - 4(-8) = 24
-8 - (-32) = 24
-8 + 32 = 24
24 = 24
y = 7x + 6
-8 = 7(-2) + 6
-8 = -14 + 6
-8 = -8

The window of a room is 20m long and 14m wide. If the
carpenter works to put a metallic frame around it which
costs Rs. 120per metre, then how much will the metallic
frame cost?
Answer:
$8160.00
Step-by-step explanation:
First find the perimeter: 40+28=68
So multiply 68 meters by the price per meter: 68*120=8160
Hope this helps!
Step-by-step explanation:
Answer:
Length =20 m
Breadth =14 m
Perimeter =2(l+b)
2(20+14)=2*34=68 m
Given cost per m =120 rs
Then the total cost =68*120=8160 rs

Answer:
the scale factor is 1/4 because the big one has four squares on the bottom so it's four times as big
A cuboid with a volume of 925cm^3 has dimensions.
4cm, (x + 1) cm and (x + 11) cm.
Show clearly that x^2 + 12x - 220 = 0
Solve the equation by factorising, making sure you show the factorisation.
State both values of x on the same line.
Finally, find the dimensions of the cuboid, writing all three on one line.
Answer:
Step-by-step explanation:
Volume of the cuboid = Length * Width * Height
Given
Length = 4cm
Width = (x+1)cm
Height = (x-11)cm
Volume of the cuboid = 4(x+1)(x+11)
Volume of the cuboid = 4(x^2+11x+x+11)
Volume of the cuboid = 4(x^2+12x+11)
Volume of the cuboid = 4x*2+48x+44
925 = 4x*2+48x+44
4x*2+48x+44-925 = 0
4x*2+48x-881 = 0
Divide through by 4
x^2 + 12x - 220.25 = 0
Factorize using the general formula;
x = -12±√12²-4(-220.25)/2
x = -12±√144+881/2
x = -12±√1025/2
x = -12±32/2
x = 12+32/2
x = 20/2
x = 10
Hence the dimension of the cuboid is 4cm, (10+1)cm and (10+11)cm
Dimension is 4cm by 11cm by 21cm

Answer:
y = 20Step-by-step explanation:
line RPN = 180 = 4y - 10 + 90 + y
180 - 90 + 10= 5y
100 = 5y
y = 100/5
y = 20

Jessica started the school year when she was 64.15 inches tall. She grew 2.87 inches during the school year. How tall, in inches, was Jessica at the end of the year? Show your work.
Answer:
67.02 inches
Step-by-step explanation:
If Jessica started out 64.15 inches and grew 2.87 inches then you know that you must add these together.
64.15 + 2.87 = 67.02
Jessica is 67.07 inches at the end of the school year.
