X^2+8x+15 is the area

because x+5 = length
and x +3 = width

(x+5)(x+3) =
x^2+3x+5x+15 =
x^2+8x+15 (area)

kojo wants to be an author. To improve his writing skills, every day after school he writes 3 pages of a story he is working on.
Aleksandr-060686 [28]

Answer:

(a) 3d=81

(b) 27

Step-by-step explanation:

every day, kojo write 3 pages

number of days he has written his story= d days

therefore number of pages he has written= 3d

from the final sentence,

3d= 81

<h3>(a) the equation to describe the situation: </h3><h3>3d= 81</h3>

(b) number of days kojo has been writing his story

3d= 81

dividing through by d

3d/3= 81/3

d = 27

<h3>therefore number of days = 27</h3>

What is the equation of the line in slope-intercept form?
kolbaska11 [484]

Answer:

The equation of the line in the slope-intercept form will be:

  • y = -7x

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where  

  • m is the slope
  • b is the y-intercept

From the attached graph, taking two points

  • (0, 0)
  • (-10, 70)

Finding the slope between (0, 0) and (-10, 70)

\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(0,\:0\right),\:\left(x_2,\:y_2\right)=\left(-10,\:70\right)

m=\frac{70-0}{-10-0}

m=-7

Determining the y-intercept:

We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.

From the graph, it is clear that:

at x = 0, y = 0

Thus, the y-intercept b = 0

Now, substituting m = -7 and b = 0 in the slope-intercept form

y = mx+b

y = -7x + 0

y = -7x

Therefore, the the equation of the line in slope-intercept form will be:

  • y = -7x
