Step-by-step explanation:

slope-intercept equation for line of slope -5/2 and y-intercept -2:

y = (-5/2)x-2

put into standard form:

(5/2)x + y = -2

5x + 2y = -4

Answer:

B. -5x-2y=4

Answer:

Step-by-step explanation:

See the picture for better visual

Take segments ST and S'T'. If we extend them they will intersect at right angle.

It is the indication that the rotation is 90° or 270° but not 180°, when the corresponding segments come parallel.

The QRST is in the quadrant IV and Q'R'S'T' is in the quadrant III, which mean the rotation is 90° clockwise or 270° counterclockwise.

This rotation rule is:

We also see the points S and T have x-coordinate of 5 but their images have y-coordinates of -6. It means the translation to the right by 1 unit was the step before rotation.

We now can conclude the correct choice is D:

Answer:

$104

Step-by-step explanation:

So, in one hour it would cost $13. Times 8, because we want to see what would be the cost for 8 hours, and 8 times 13 is 104.

Answer:

104.5 and 105.5

Step-by-step explanation:

Unless there are such things are 1/2 room numbers, there is no answer. But algebraically, x + x + 1 = 2x + 1 = 210

2x + 1 = 210

2x = 209

x = 104.5

Answer:

[tex]x = -2.11490754, 0.25410168, 1.86080585[/tex]

Step-by-step explanation:

The roots (zeros) are the x values where the graph intersects the x-axis. To find the (zeros), replace y  with 0 and solve for x.

Answer:

y = 2x ± 3

························

Step 1.  The first blank is found at the point in which the line crosses the x- axis

Step 2. The second blankis found at the point in which the line crosses the y- axis

In this case those two points are 2 and 3

Step-by-step explanation:

Answer:

[tex]q = -6p + 104[/tex]

Step-by-step explanation:

Linear function:

A linear function has the following format:

[tex]q = mp + b[/tex]

In which m is the slope and b is the q-intercept.

One week you charged $4 per guest and averaged 80 guests per night. The next week you charged $10 per guest and averaged 44 guests per night.

This means that we have these following points: (4,80), (10,44).

Finding the slope:

With a pair of points, the slope is given by the change in q divided by the change in p.

Change in q: 44 - 80 = -36

Change in p: 10 - 4 = 6

Slope: [tex]m = \frac{-36}{6} = -6[/tex]

So

[tex]q = -6p + b[/tex]

Finding b:

We replace one of the points. Replacing (4,80).

[tex]q = -6p + b[/tex]

[tex]80 = -6*4 + b[/tex]

[tex]b = 104[/tex]

So

[tex]q = -6p + 104[/tex]

Q1

Q2

Answer:

f = 2.25

Step-by-step explanation:

Given that,

[tex]f-\dfrac{3}{4}=1\dfrac{1}{2}\\\\f-\dfrac{3}{4}=\dfrac{3}{2}[/tex]

Adding 3/4 to both sides of the equation.

[tex]f-\dfrac{3}{4}+\dfrac{3}{4}=\dfrac{3}{2}+\dfrac{3}{4}\\\\f=\dfrac{6+3}{4}\\\\f=\dfrac{9}{4}\\\\f=2.25[/tex]

So, the value of f is equal to 2.25.
