Answer:

(-2,6)

Step-by-step explanation:

3x + 2y = 6

-3x + y = 12

3x + -3x = 0

2y + y = 3y

6 + 12 = 18

3y = 18

3y/3 = 18/3

y = 6

-3x + y = 12

-3x + 6 = 12

-3x = 12 - 6

-3x = 6

-3x/-3 = 6/-3

x = -2

Answer:

Step-by-step explanation:

you just need to add both equations

you will get 3y=12+6=18

3y=18

y=6

now replace y=6

3x+12=6

3x=6-12

3x=-6

x=-2

F(x) =5x^2-20x+3 how to find minimum
Leya [2.2K]

Answer:

(2,-17) should be the minimum.

Step-by-step explanation:

The minimum of a quadratic function occurs at x=-\frac{b}{2a} . If a is positive, the minimum value of the function is f(-\frac{b}{2a})

f_{min}x=ax^2+bx+c occurs at x=-\frac{b}{2a}

Find the value of x=-\frac{b}{2a}

x = 2

evaluate f(2).

replace the variable x with 2 in the expression.

f(2)=5(2)^2-20(2)+3

simplify the result.

f(2)=5(4)-20(2)+3

f(2)=20-40+3

f(2)=-17

The final answer is -17

Use the x and y values to find where the minimum occurs.

HOPE THIS HELPS!

The lengths of the sides of a triangle are x,x+1 and 7 centimeters and the perimeter of the triangle is 56 centimeters. The equa
____ [38]

Answer:

the longest side is 25

Step-by-step explanation:

the equation would be x+ x+1 + 7  for the 3 sides of the triangle

x + (x+1) + 7=56

combine like terms

2x+8 = 56

subtract 8 from each side

2x = 48

divide by 2

x = 24

the sides are

x=24

x+1 = 25

7

the longest side is 25
