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
Hello,
Roots are -3+2i,-3-2i,-2 and -2
There are 4 roots. (theorem of the conjugate roots) and the least degree of the polynomial is
4.
(f+g-k)(x) means to add the equations f(x) and g(x) then subtract k(x)
2x^2 + 3x + 4x - 9 = 2x^2 +7x -9
2x^2 + 7x - 9 - x^2 -7x = x^2 -9
The answer is : x^2 - 9
3 cm on the map represents 31.5 km in reality.
3cm : 31.5 km
1cm : 31.5/3 km
1cm : 10.5km
So the scale on the map is 1cm represents 10.5 km.
8.
2 terms on left side, 3 on right side
9.
All variables count as coefficients, so they’d be 8m, k, and -16k
10.
The constants are just numbers on their own, or without a variable next to it. Here it’d be 10 and -4
