A function is expressed by the equation y=0.3x−6. For what value of the independent variable will the value of the function be e

<span>For two vectors u and v, the cross product can be expressed as follows: (u2v3 - u3v2) i + (u3v1 - u1v3) j + (u1v2 - u2v1) k. Consequently, we have m x n: ( (2 *-4) - (-5 * -2) ) i + ( (-5*6) - (3 *-4) )j + ( ( 3*-2) - (2*6))k, which simplifies to ( -8 - 10) i + ( -30 + 12) j + ( -6 - 12) k. Thus, the product of vectors m and n yields -18 i - 18j -18k</span>.

Answer:

1. 8.4 2. 15

Step-by-step explanation:

1. 4x + 8y = 40

when y = 0.8

4x + 8 × 0.8 = 40

4x = 40 - 8 × 0.8

4x = 40 - 6.4 = 33.6

....x = 33.6 / 4 = 8.4

2. 3a + b = 54

when b = 9

3a + 9 = 54

3a = 54 - 9

3a = 45

.....a = 45 / 3 = 15

Response:

First, subtract one-half from each side of the equation.

Next, divide both sides by 6/7.

Then, multiply each side by 7/6.

Response:

$125,000.12 last year

$375,000.36 this year

Step-by-step clarification:

Last year, her earnings were x.

This year, her earnings are three times greater, thus they equal 3x.

For both years combined, the total earnings amount to x + 3x = 4x.

The earnings across both years together total $500,000.48

4x = 500,000.48

Dividing both sides by 4 gives us

x = 500,000.48/4

x = 125,000.12

Thus, last year's earnings were $125,000.12

This year, her profits amounted to 3x = 3(125,000.12) = 375,000.36, totaling $375,000.36
