1)
15 > -2x-9
15+9 > -2x
24÷(-2) < x (the sign flips because you divide both sides by a negative number)
Hence, x > -12
2)
3x + 8 < 29
3x < 29-8
3x < 21
x < 7 (tada the answer)
Maybe if multiply 80 by 3 so you can find one of the answer then do it algebraic
Answer:
77 ft²
Step-by-step explanation:
Given that:
Surface Area of larger pyramid = 539 ft²
Scale factor of the smaller pyramid = 1/7
Tbe surface area of the smaller pyramid will be :
Scale factor * surface area
1/7 * 539ft²
= 539 ft² / 7
= 77 ft²
Answer:
(g o h)(5) = 4
Step-by-step explanation:
h(x) = x - 7
g(x) = x^2
(g o h)(5) = ?
(g o h)(x) = g(h(x)) = (x - 7)^2
(g o h)(5) = (5 - 7)^2 = (-2)^2 = 4
