- The given equation is:
Where, a = 1 , b = 2 , c = -120
- Solve using quadratic formula:
Value of expression is 22 .
<u>Step-by-step explanation:</u>
Here we have the following expression to solve :
8÷2*5+(6-4)
⇒
⇒
But 8 = 4(2) , So
⇒
⇒
⇒
⇒
⇒
Therefore, Value of expression is 22 .
The first question is “32.4”
I’ll come back if I find the other
7,000+500+2
2(3751)
7x10^3+5x10^2+2X10^0
5(1500.4)
Answer :
m = 3
Point = (4,-1)
x1 = 4
y1 = -1
Formula =
y - y1 = m (x-x1)
y - (-1) = 3 (x -4)
y + 1 = 3x -12
y - 3x + 1 + 12 = 0
y - 3x + 13 = 0
The line = y - 3x + 13 = 0 or -3x + y + 13 = 0
I'm sorry if I'm wrong.
