Answer:

The values of h and k for a linear system with infinitely many solutions are -2 and 5, respectively.

Step-by-step explanation:

Let 2\cdot x_{1}+5\cdot x_{2} = -1\cdot h\cdot x_{1} + k\cdot x_{2} = 7, if this linear system has infinitely many solutions, then the following conditions must be met:

-1\cdot h = 2 and k = 5.

h = -2 and k = 5

The values of h and k for a linear system with infinitely many solutions are -2 and 5, respectively.

What if f(-2) for f(x)=1/2x 2 squared
Alexeev081 [22]

Answer:

2

Step-by-step explanation:

Given

f(x) = \frac{1}{2} x²

To evaluate f(- 2), substitute x = - 2 into f(x)

f(- 2) = \frac{1}{2} × (- 2)² = \frac{1}{2} × 4 = 2

READ THE PROBLEM WITH UNDERSTANDING AND SHOW THE SOLUTION
liq [111]

Answer:

Step-by-step explanation:

1)  the equation would be:

(2x+4)x(5x+1) because if the amount of ballpens are (2x+4) and the ballpens are $(5x+1) each, you would multiply them.

this is the expanded version of (2x+4)(5x+1)
{10x^2 + 2x + 20x + 4

10x^2 + 22x + 4}


2) (x^2 +1)(x+2) are multiplied to find the volume of the box

So when expanded it looks like this:

{x^3 + 2x^2 + x + 2}


3) (15a^2b^3) would be multiplied with (2a). This is because to find the total you would times the numbers.
so when expanded:

(15a^2b^3)(2a)

{(15a^3)(2ab^3)}


4) 5X(x+8)=33

5x+40=33

5x=33-40

5x=-7

X= -7/5


5) x-8=8x

8x-x = -8

7x=-8

X=-8/7


Hope this helps :)
