4x + 3y = 6<br> 3x + 5y = -1<br> Solve the simultaneous equations.<br><br> y= <br> z=
Kisachek [45]

Answer:

x=3, y= -2

Step-by-step explanation:

Multiplying :

(4x+3y =6)*-3

(3x+5y =-1)*4

-12x -9y= -18

12x+20y= -4

Add the equations

20y-9y = -4-18

11y = -22

y= -22/11 = -2

3x +5* -2= -1

3x -10 = -1

3x = 10-1

x= 9/3 =3

Help with my homework <br> Evaluate the exponent expression for a = 1 and b = –2.
Snowcat [4.5K]

Answer:

  -1/16

Step-by-step explanation:

Put the values where the variables are and do the arithmetic.

1 to any power is 1, so you can ignore all of the 'a' factors. That leaves ...

  1/(2b^3) = 1/(2(-2)^3) = 1/(2(-8)) = -1/16

___

A calculator can help you figure this out.

Please help ASAP. Thanks so much.
MAVERICK [17]

Answer:

B. 3

Step-by-step explanation:

To find the value of c, substitute the x and y values of the given point into x and y of the equation, then isolate c. Since that given point is (2,5), substitute 2 for x and 5 for y:

(5) = -2(2)^2+8(2)-c\\5 = -2(4)+16-c\\5 = -8 + 16 - c \\5 = 8 -c\\-3 = -c\\c = 3

Thus, c = 3.
