It is 4.50+20y=100 bc its y=mx+b
Answer:
4th option
Step-by-step explanation:
(f - g)(x)
= f(x) - g(x)
= 
- (3x² - 3x - 5)
= 4x² - 3x² + 3x + 5 ← collect like terms
= x² + 3x + 5
Answer:
Step-by-step explanation:
The square base measures 8 inches by 8 inches. The slant height is 10 inches.
The formula for determining the area of the square base of the pyramid is l^2. Therefore,
Area of the base = 8^2 = 64 inches^2
The formula for determining the perimeter of the square base is
4l. It becomes
4 × 8 = 32 inches
The amount of construction paper needed to make this pyramid is the total surface area of the pyramid. Therefore,
Total surface area = (1/2 × 32 × 10) + 64
= 160 + 64 = 224 inches^2
Answer:
hope this helps u!
Step-by-step explanation:
Y - 3x = 7 . . . . . . . . (1)
21 + 9x = 3y . . . . . .(2)
From (1), y = 3x + 7
substituting for y into (2), we have
21 + 9x = 3(3x + 7) = 9x + 21
0 = 0
Therefore, the system has an infinte number of solutions.
