3 0

Step-by-step explanation:

By binomial theorem,

T(r+1) = nCr * a^(r+1) * b^r

Term 4 = 7C3 * (2x)^4 * (-5y)^3 = 35 * (16x^4) * (-125y^3) = -70000x^4y^3.

Given that 3(x-c)=2x+5 where c is an integer, shoe that x cannot be a multiple of 6

olga nikolaevna [1]

Answer:

The explanation in the procedure

Step-by-step explanation:

we have

$3(x-c)=2x+5$

solve for c

$3x-3c=2x+5$

$3c=3x-2x-5$

$3c=x-5$

$c=(x-5)/3$

For $x=6$ -----> Find the value of c

$c=(6-5)/3=1/3$ ------> is not an integer

therefore

x cannot be a multiple of 6

A system of linear inequalities is shown above. ( in the picture )

astraxan [27]

Answer:

C. (0, -3)

Step-by-step explanation:

The given system is

$- 2x - 3 \leqslant y$

$y - 1 \: < \: \frac{1}{2} x$

The point that satisfies both inequalities is the solution to the system.

When x=0 and y=-3.

We substitute into the first inequality to get:

$- 2(0) - 3 \leqslant - 3 \\ - 3 \leqslant - 3...true$

We again substitute into the second inequality to get:

$- 3- 1 \: < \: \frac{1}{2} (0) \\ - 4 \: < \: 0....true$

The point (0,-3) is a solution to the system of inequalities.
