Answer:
The y-intercept would be 6.25
Step-by-step explanation:
I found this by taking the two points and making it into a y = mx + b line.
Hello!
<span>To transform the normal, standard numbering to centric notation, simply remove the zeros prior to the point, and raise the remainder to the number of zeros in their negative form.
0.0078 = 7.8 * 10 -3.

Answer:
(- 3, - 2 )
Step-by-step explanation:
Given the 2 equations
- 2x + 5y = - 4 → (1)
3x + 4y = - 17 → (2)
Multiplying (1) by 3 and (2) by 2 and adding the result will eliminate x
- 6x + 15y = - 12 → (3)
6x + 8y = - 34 → (4)
Add (3) and (4) term by term
(- 6x + 6x) + (15y + 8y) = (- 12 - 34), that is
23y = - 46 ( divide both sides by 23 )
y = - 2
Substitute y = - 2 in either of the 2 equations.
Substituting in (2)
3x - 8 = - 17 ( add 8 to both sides )
3x = - 9 ( divide both sides by 3 )
x = - 3
Solution is (- 3, - 2 )
The value of x is -9 and 3.Option D.
Step-by-step explanation:
Given,
To find the value of x.
We will apply middle term factor formula.
The given equation can be written as,
or, 
+(9-3)x-27 = 0
or, x²+9x-3x-27= 0
or, x(x+9)-3(x+9)=0
or, (x+9)(x-3) = 0
So, x = -9 and x = 3
Hence,
The correct option is Option D.
- Principal=P=4000
- Time=T=2years
- Rate of interest =R=36
Interest be I
Now
Final value=4000+2880=6880
