It is not equivalent because 3 (5x)= 15x while (3×5) (3×x)=15+3x they turn out different when you do the distributive property
Answer:
1 i.e. n
Step-by-step explanation:
Answer:
option D
(-1,-3) and (3,13)
Step-by-step explanation:
Given in the question two equations
y = 4x + 1
y = x² + 2x - 2
Equate both functions
4x + 1 = x² + 2x - 2
rearrange the x term and constant
-x² + 4x - 2x + 2 + 1 = 0
-x² + 2x + 3 = 0
factors
-x * 3x = -3x²
-x + 3x = 2x
-x² -x + 3x + 3 = 0
-x(x+1) +3(x+1) = 0
solve
(x+1)(3-x) = 0
x = -1
and
x = 3
Plug these values in equation to find y
x = -1
y = 4(-1)+ 1
y = -3
x = 3
y = 4(3)+ 1
y = 13
Answer: V = 3,052.08 cubic meters
Step-by-step explanation:
V = (4/3)(3.14)(r^3)
V = (4/3)(3.14)(9^3)
V = 3,052.08
Answer:
$208
Step-by-step explanation:
Total amount earned is given as:= 8x + 7y
The number of hours worked at a restaurant = x hours
The number of hours worked at a bus
station = y hours
How much do you earn for working 12 hours at the restaurant and 16 hours at the bus station?
= 8(12) + 7(16)
=96 + 112
= $208
