Solution:

we have been asked to find a function for the given sitatution

The given situation is

A movie store sells DVDs for $11 each. what is the cost C of n DVDs.

Cost of 1 DVD is $11, then the cost of 2 DVDS will be 2x11=$22.

Cost of 1 DVD is $11, then the cost of 3 DVDS will be 3x11=$33.

......................................................................................................................

.......................................................................................................................

Cost of 1 DVD is $11, then the cost of n DVDS will be nx11=$11n.

Since the price is increasing exactly by $11 for each additional DVDS so the Graph will be discrete.

Hence the correct option is C=11n, Discrete.

Which congruence criteria can be used directly from the information about triangles HIJ and MNO to prove IJ¯¯¯¯¯¯≅MN¯¯¯¯¯¯¯¯¯¯ b

skelet666 [1.2K]

Answer: $\overline{IJ}\cong \overline{MN}$

Step-by-step explanation:

Given: In triangle HIJ and triangle MNO we have

$\overline{HI}\cong \overline{NO}, \angle{I}\cong \angle{N} ,\angle{H}\cong \angle{O}$

here, HI and NN are the included side between ∠I & ∠H and ∠N and ∠O.

So , by ASA congruence rule,

ΔHIJ ≅ ΔMNO

So by CPCTC (corresponding parts of the congruent triangles are congruent)

$\overline{IJ}\cong \overline{MN}$

Answer:

y = x + 5

Step-by-step explanation:

1) First, find the slope of the line $x-y = 4$ . We can do this by setting it up in slope-intercept form, represented by the equation $y = mx + b$ . Whatever $m$ or the coefficient of the x-term is will be the slope. Isolate y in the equation:

$x-y = 4\\-y = -x+4\\y = x -4$

So, the slope of the given equation is 1. Parallel lines share the same slope, thus the slope of the new line will be 1 as well.

2) Now, use the point-slope formula $y-y_1 = m (x-x_1)$ to write the equation of the line in point-slope form. Substitute values for $m$ , $x_1$ , and $y_1$ in the formula.

Since $m$ is the slope, substitute 1 for it. Since $x_1$ and $y_1$ represent the x and y values of one point the line passes through, substitute the x and y values of (-6, -1) into those places as well. Then, isolate y in the resulting equation to put the equation in slope-intercept form and find the answer:

$y-(-1) = 1 (x-(-6))\\y + 1 = 1 (x + 6)\\y + 1 = x + 6\\y = x + 5$
