Answer:

$x = 75\degree$

Step-by-step explanation:

In $\triangle BDH,\: \angle x$ is the exterior angle.

$\implies x = 36\degree + 39\degree$ (By exterior angle theorem)

$\implies x = 75\degree$

Use the remainder theorem to find the remainder of 2x^4 + x^2 - 10x -1 divided by x +2.

I am Lyosha [343]

Answer:

The remainder is 55

Step-by-step explanation:

Let

$p(x)= 2 {x}^{4} + {x}^{2} - 10x - 1$

According to the remainder theorem, if p(x) is divided by x+a, the remainder is p (-a).

The given divisor is x+2, therefore the remainder is given by:

$p( - 2)$

We substitute x=-2 to get:

$p( - 2)= 2 {( - 2)}^{4} + {( - 2)}^{2} - 10( - 2) - 1$

We simplify to obtain:

$p( - 2)= 2 \times 16 + 4 + 20- 1$

We multiply to get:

$p( - 2)=3 2 + 4 + 20- 1 = 55$

Therefore the remainder is 55

Answer:

The slope of function A is 2 times the slope of function B.

Step-by-step explanation:

In function A, every-time the input goes up 1 the output will also go up one. In function B, every time the input goes up by 1, the output goes up by two. Therefore, the slope of function A is 1 but the slope of function B is 1/2.

FinnZ [79.3K]

Answer:

Step-by-step explanation:

For this equation we have to plug in, so z= 6 and w=7. the question is 8z+7w

so plug in 6 for z and 7 for w. 8(6)+7(7) so 8*6 is 48 and 7*7= 49. 48+49= 97

hope this helps :)
