Answer: x = 157
Step-by-step explanation:
Switch sides:
Divide both sides by 6:
Simplify:
Answer:
x = 16
Step-by-step explanation:
12(x - 20) = -48
Use distributive property
12*x - 12*20 = -48
12x - 240 = -48
Add 240 to both sides
12x = -48 + 240
12x = 192
Divide both sides by 12
x = 192/12
x = 16
Pretty sure it’s going to be D.
LC=1
Step-by-step explanation:
f(x)=x^2-8x-4
=(1)x^2-8x-4
Answer:
Value of d is:
48
Step-by-step explanation:
We are given a matrix M as:
M=
We are given that:
a=19, b=24 and c=38
We have to find the value of d so that M is singular
i.e. determinant of M=0
i.e. ad-bc=0
i.e. 19d-24×38=0
i.e. 19d=24×38
i.e. d=
i.e. d=48
Hence, Value of d is:
48
