Step-by-step explanation:

The slope of the line passing through two points is given by,

$\frac{y2 - y1}{x2 - x1}$

13)

$\frac{(0 - y)}{(0 - 2)} = (\frac{ - 3}{2} )$

$\frac{ - y}{ - 2} = \frac{ - 3}{2}$

$y = - 3$

option D

14)

$\frac{ ( - 3 - y)}{(1 + 5)} = \frac{ - 1}{6}$

$\frac{ - 3 - y}{6} = \frac{ - 1}{6}$

$- 3 - y = - 1$

$- y = - 1 + 3 = 2$

$y = - 2$

option C

15)

$\frac{(y - 4)}{( - 5 + 1)} = \frac{1}{4}$

$\frac{y - 4}{ - 4} = \frac{1}{4}$

$- y + 4 = 1$

$- y = 1 - 4 = - 3$

$y = 3$

option B

16)

$\frac{(y + 3)}{( - 4 - 3)} = \frac{ - 3}{7}$

$- (y + 3) = - 3$

$y = 3 - 3 = 0$

option C

Answer:

h(g(x)) = (1/5)x² +4/5

Step-by-step explanation:

$(h\circ g)(x)=h(g(x))=h(x^2+2) = \dfrac{(x^2+2)+2}{5}=\dfrac{x^2+4}{5}\\\\\boxed{(h\circ g)(x)=\dfrac{1}{5}x^2+\dfrac{4}{5}}$

Find the volume of the cylinder. 30 POINTS :0!!

klemol [59]

Formula: V = PI x r^2 x H

Volume = 3.14 x 4^2 x 10

Volume = 3.14 x 16 x 10

Volume = 3.14 x 160

Volume = 160π or 502.4 units^3

5. Henry hit 3 more than half as many home runs as Jack hit last season. Henry hit a total of 8 home runs. a. Make Sense and Per

Evgesh-ka [11]

Answer:

a. $3+\frac{x}{2} =8$

b. x = 10

Step-by-step explanation:

a. The number of home runs hit by Jack last season = x

It is given that Henry hit 3 more than half as many home runs as Jack hit.

Half of the runs hit by Jack = $\frac{x}{2}$

3 more than half the runs = $3+\frac{x}{2}$

So, the number of home runs hit by Henry = $3+\frac{x}{2}$

But, it is given that Henry hit a total of 8 runs.

Therefore, $3+\frac{x}{2} =8$

b. $3+\frac{x}{2} =8$

Subtract 3 from both sides.

$\frac{x}{2} =8-3$

= 5

x = 5 × 2

= 10

Hence, Jack hit 10 runs in the last season.
