1. 2
2. The Y axis
3. 3 rights and 1 down (3, -1)
Answer:
Assume as book to be x and pen to be y.
3x+2y=395 equation 1
2x+5y=355 equation 2
Make any variable either x or y to be equal.
3x*2+2y*2=395*2
2x*3+5y*3=355*3
Here, I am making x as same so I cross multiplied
6x+4y=790 equation 3
6x+15y=1065 equation 4
Put minus sign in any one of the equation 3 or equation 4 in order to cancel out x.
6x+4y=790
-6x-15y= -1065
0 - 11y= - 275
y= - 275/ - 11
y= 25
As we got y, we can put the value of y in equation 1 or equation 2.
3x+2y=395
3x+2*(25)=395
3x+50=395
3x=395-50
3x=345
x=345/3
x=115
As we assumed the book to x and pen to be y
price of book = Rs. 115
price of pen= Rs. 25
Answer:
E = 3072i - 5904ohms
Step-by-step explanation:
From ohms law recalled that E = IR given already
E = voltage (volts)
I = Current (amps)
R = resistance (ohms)
Therefore, by substitution
I = 16i and R = (2+4)ohms(32+66i)
= 6(32+66i) ohms
= (192+396i)ohms
E = (16i)×(192+396i)
E = 3072i + 5904i²
Recall that i² = -1 from complex number
E = 3072i +5904(-1)
E = 3072i - 5904ohms
Answer:
68
Step-by-step explanation:
(x + 4)/ 6^2 = 2
x+4= 2(36)
x= 72-4
x=68
we have
Divide both sides by 
Square root both sides
so
the solutions are
therefore
<u>the answer is the option</u>
x = 2/3 and x = -2/3
