Solve 2y = 6x + 10 y = 2x + 4

mihalych1998 [28]

Answer:

x =-1

Step-by-step explanation:

$\left \{ {{2y = 6x +10} \atop {y = 2x +4}} \right.$

replace y by 2x +4 in the first equation

2(2x + 4) = 6x + 10

4x + 8 = 6x + 10

-2x +8 = 10

-2x = 2

x = -1

The function f is continuous son the interval [2, 10] with some of its values given in the table below. Use a right Riemann Sum

Marta_Voda [28]

The 4 subintervals are given: [2, 4], [4, 7], [7, 9], and [9, 10].

Each subinterval has length: 4 - 2 = 2, 7 - 4 = 3, 9 - 7 = 2, and 10 - 9 = 1.

Over each subinterval, we take the value of the function at the right endpoint: 3, 8, 15, and 18.

Then the integral is approximately

$\displaystyle\int_2^{10}f(x)\,\mathrm dx\approx3\cdot2+8\cdot3+15\cdot2+18\cdot1=78$

so 78.0 is the correct answer.

Answer:

2(9w - 3)

Step-by-step explanation:

6w + 3(4w - 2) = ? ( ? - 3)

6w + 12w - 6

18w - 6

2(9w - 3)

6w + 3(4w - 2) = 2(9w - 3) <===
