The solution to the system of equation is (-0.6, 1.6)

<h3>
System of linear equations</h3>

Given the system of linear equations as shown:

y = 2/3x+ 2 .................. 1

6x - 4y = -10................ 2

Substitute equation 1 into 2 to have:

6x - 4(2/3x + 2) = -10
6x - 8/3 x - 8 = -10
10/3 x = -2

10x = -6

x =-0.6

Determine the value of y

y = 2/3x + 2

y = 2/3 (-0.6) + 2

y = -0.4 + 2

y = 1.6

Hence the solution to the system of equation is (-0.6, 1.6)

A triangle has two sides of lengths 7 and 9.what value could the length of the third side be?
Diano4ka-milaya [45]
The side length has to be between 2 (=9-7) and 16 (=9+7). In both these corner cases the triangle will have collapsed to a line.

So the correct answers are B,C,D and E, and F is a corner case. Theoretically I suppose you have to count F in as a valid answer.

If h(x) = 2x4 - 4x2 - 2x, then h(3)= ? A) -6 B) 120 C) 192 D) 1146 E) 1434
garik1379 [7]

The value of h(3) is 120 ⇒ B

Step-by-step explanation:

To find the value of f(x) at x = a, do that

  • Substitute x by a
  • Find the value of f(a)

∵ h(x)=2x^{4}-4x^{2}-2x

- To find h(3) substitute x by 3

∴ h(3)=2(3)^{4}-4(3)^{2}-2(3)

∵ (3)^{4} = 81

∵ (3)² = 9

- Substitute them in the function above

∴ h(3) = 2(81) - 4(9) - 2(3)

∴ h(3) = 162 - 36 - 6

∴ h(3) = 120

The value of h(3) is 120
