Answer:
y= -1/4 x+4
Step-by-step explanation:
1. Solve for y
2. Use the same equation you just got without the 7 (b value) and plug in the new point (8,2) into the x and y
3. Solve for b
4. Final equation includes the slope found in step 1 and the new b value
(3.7 x 104)2 = 769.6
In Scientific notation:
7.696 x 10^2
Answer:
x=30
Step-by-step explanation:
5=x/6
30=x
Answer:
x =(5/3)
Step-by-step explanation:
The given expression is 
Now to simplify it,
The first step is to cross multiply.
So, the expression becomes

or, -1 = 3x - 6
⇒ 3x = -1 + 6
⇒ 3x = 5 , or x =(5/3)
Answer:
d. 20
Step-by-step explanation:
The given question implies 5 permutation 2, i.e 
.
But,

= 
So that for 
, n = 5 and r = 2.

= 
= 
= 
Cancel out 3 and 2 with respect to the numerator and denominator.

= 5 * 4
= 20
Therefore,

= 20
So that the correct option is D.
