x=-½ y=0
Step-by-step explanation:
y=2x+1
y=6x-1. this means that
2x-1=6x+1
2x-6x=1+1.
-4x=2. divide both sides by -4
x=-½
thus y=2x-1
y=1-1
y=0
Answer:
SA = 480 cm²
Step-by-step explanation:
Surface area of the composite figure given in the picture = (Surface Area of the triangular prism on the top - area of the rectangular base) + (Surface area of the rectangular prism - Area of the rectangular base)
Surface area of the triangular prism = Area of the triangular bases + (perimeter of the base × Height)
= + [(5 + 5 + 8)×12]
= 24 + 216
= 240 cm²
Area of the rectangular surface of the prism = 8 × 12 = 96 cm²
Surface area of the rectangular prism = 2(lb + bh + hl)
Here, l = Length, b = width and h = Height of the rectangular prism
= 2(8 × 12 + 12 × 6 + 6 ×8)
= 432 cm²
Surface area of the composite figure = (240 - 96) + (432 - 96)
= 144 + 336
= 480 cm²
Answer:
If P(x) has the roots -11 and 6, then its multipliers can be written as
Step-by-step explanation:
P(x)=(x+11)(x-6)
P(x)=x2-6x+11x-66
P(x) = x2+5x-66
Answer:
12 1/3 years
Step-by-step explanation:
Let
x = his son's age
Grandpa Burk's age = 52 + x
In five years Grandpa Burk will be four Times as old as his grandson is now.
his son's age = 4(x + 5)
Grandpa Burk's age = 52 + x + 5
= x + 57
4(x + 5) = x + 57
4x + 20 = x + 57
4x - x = 57 - 20
3x = 37
x = 37 / 3
= 12 1/3 years
His son's age will be 12 1/3 years
