21 I believe if you plus a negative it’s basically subtracting so 21+-2 =19

<h2>                             Question 1</h2>

Answer:

The graph is showing the story.

Step-by-step explanation:

Victoria is on the 13th page of the book, she reads 3 pages after every next hour.

After 1st hour she has read = 13 + 3 = 16

As she reads 3 pages after every next hour.

so

After 2nd hour she has read = 16 + 3 = 19

After 3rd hour she has read = 19 + 3 = 22

After 4th hour she has read = 22 + 3 = 25

After 5th hour she has read = 25 + 3 = 28

So the graph is showing this phenomena.

<h2>                          Question 2</h2>

Answer:

The equation that would generate this graph and table would be:

  • y=\:3x+13

Step-by-step explanation:

Given the slope-intercept form of the equation of the line

y=\:mx+b

Taking any two points

(1, 16)

(2, 19)

\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(1,\:16\right),\:\left(x_2,\:y_2\right)=\left(2,\:19\right)

m=\frac{19-16}{2-1}

m=3

Plugging any point, let say (1, 16), and m = 3 in the slope-intercept form to find the value of b (y-intercept).

y=\:mx+b

16=\:3\left(1\right)+b

\mathrm{Switch\:sides}

3\left(1\right)+b=16

\mathrm{Remove\:parentheses}:\quad \left(a\right)=a

3\cdot \:1+b=16

\mathrm{Multiply\:the\:numbers:}\:3\cdot \:1=3

3+b=16

\mathrm{Subtract\:}3\mathrm{\:from\:both\:sides}

3+b-3=16-3

b=13

Thus the equation that would generate this graph and table is:

y=\:mx+b

  • m = 3
  • b = 13

y=\:3x+13

Therefore, the equation that would generate this graph and table would be:

  • y=\:3x+13

Secant RM intersects secant RN at point R. Find the length of RQ. If necessary, round to the hundredths place.
QveST [7]

Answer:

3 Units

Step-by-step explanation:

Secant RM intersects secant RN at point R.

The secants intersects the circle at points P and Q respectively as seen in the diagram.

To determine the length of RQ, we use the Theorem of Intersecting Secants.

Applying this on the diagram, we have:

RP x RN=RQ X RM

4(4+5)=RQ(RQ+9)

Let the length of RQ=x

4*9=x^2+9x\\36=x^2+9x\\x^2+9x-36=0\\x^2+12x-3x-36=0\\x(x+12)-3(x+12)=0\\(x+12)(x-3)=0\\x+12=0$ x-3=0\\x=-12 or x=3\\Since x cannot be negative$\\x=|RQ|=3

Therefore, length of RQ=3 Units

HELP!!!! If point P(-6,4) is translated 3 units right and 2 units down, what are the coordinates of P''?
Ipatiy [6.2K]

Answer:

P" is then (-3, 2).

Step-by-step explanation:

If the point P(-6, 4) is translated 3 units to the right, the x-coordinate increases by 3 from -6 to -3 and the y-coordinate decreases 2 units from 4 to 2.

P" is then (-3, 2).
