Answer: y+ 7 = 5x
Step-by-step explanation:
A linear function is a function in which the highest power of the unknown is 1 , that is , the highest power of the variables that are unknown will be 1.
From the question given:
A : 1 - 
= -y
The power of x is 2 , though the power of y is 1 but because of the existence of the power of x which is 2 , it is not linear
B : y + 7 = 5x
both the power of x and y is 1 , so it is a linear function
C: 
+ 4 = y is not linear
D is also not linear
likewise , E is not linear
Therefore , B is the only linear function
Answer:
X=6,-4
Step-by-step explanation:
0=x^2-2x-24
First substitute x with 6
0=(6)^2-2(6)-24
36-12-24
=0
Now try -4
0=(-4)^2-2(-4)-24
Two negative numbers time each other turns it into a positive number -4 x -4=16
24-24=0
Answer:
k = 7
Step-by-step explanation:
given y varies jointly with x and w then the equation relating them is
y = kxw ← k is the constant of variation
to find k use the condition when y = - 42, x = 2 and w = - 3 , then
- 42 = k × 2 × - 3
- 42 = - 6k ( divide both sides by - 6 )
7 = k
constant of variation is k = 7
The answer is c. 72cm^2
for each section of the prism you multiply the length times the width and then add all of the numbers together to get 72
