interval:  -2 ≤ x ≤ 2

Find 2 coordinate points on the graph where x = -2 and x = 2:

(-2, 2)  and (2, -2.5)

Let [tex](x_1,y_1)[/tex] = (-2, 2)  and  [tex](x_2,y_2)[/tex] = (2, -2.5)

rate of change = [tex]\frac{y_2-y_1}{x_2-x_1}=\frac{-2.5-2}{2+2} =\frac{-4.5}{4}=-\frac{9}{8}[/tex]

Answer:

The slope should be m= 4/7

Step-by-step explanation:

i hope this helps a little <3 have a awesome day

Answer:

m = 4/7

Step-by-step explanation:

The question is asking us to find the slope.

The function is:

[tex]\boldsymbol{y=\dfrac{4}{7}x-\dfrac{5}{8}}[/tex]

Notice that the form of this equation is y = mx + b, which is known as slope-intercept.

Slope-intercept is the most common way of writing the equation of a straight line.

The slope, m, is the coefficient of x. So we look at that number if we need to find the slope. For this particular function, the slope is 4/7.

The y-intercept, b, is the constant. For this function, the y-intercept is -5/8.

Therefore, m = 4/7.

Answer:

The perimeter of the pentagon ≅ 19 units (approximately)

Step-by-step explanation:

Clockwise, starting from the base of the pentagon, we have:

The base of the pentagon or bottom side ≅ 4 units

2nd side ≅ 3.75 units

3rd side ≅ 3.75 units

4th side ≅ 3.75 units

5th side ≅ 3.75 units

In consequence,

Perimeter of the pentagon ≅ 4 + 3.75 + 3.75 + 3.75 + 3.75

The perimeter of the pentagon ≅ 19 units

Answer:

x = 3.8

Explanation:

−2.7 (x−1.4)=−6.48

(−2.7)x + (−2.7)(−1.4) = −6.48

−2.7x+3.78= −6.48

-2.7x = −6.48 - 3.78  ....changing sides, turns + integer to -

-2.7x = -10.26

x = -10.26/ -2.7  ....changing sides, turns * integer to /

x = 3.8

Answer:

3. 6

4. 19

Step-by-step explanation:

3. [tex]36^{\frac{1}{2} }e^\frac{16}{2} f^\frac{64}{2} =6 e^8f^{32}[/tex] so the coefficient is 6

4. [tex]x^4(x^5)^3=x^4x^{15}=x^{4+15}=x^{19}[/tex] so m=19

Answer:

-4 = k/-5

k=20

the sum of all interior angles in a polygon is

180( n - 2)

n = number of sides

now, this polygon is a quadrilateral, so it has 4 sides, so it's total is just 180( 4 - 2) = 360.

[tex]360=x+4x+3x+2x\implies 360=10x\implies \cfrac{360}{10}=x\implies 36=x[/tex]

Answer:

x = 36

Step-by-step explanation:

The angles of a trapezoid add up to 360, so add x, 4x, 3x, 2x to get 10x

10x = 360

360/10 = 36

Therefore, x = 36

Answer:

4.56

Step-by-step explanation:

i see a sector hosting 2 semi circles.

this sector area will be .25 of area of circle with radius 4ft.

area of sector = .25*π*16= 4π ft^2

area of semi circle of radius 2ft = .5π*4= 2πft^2

area of 2 semicircles = 4π

the total area of sector = area of 2 semicircles - intersection area + area not covered by semi circles

4π = 4π - intersection area+area not covered by semi circles

intersection area = area not covered by semi circles

now draw a square starting from the intersection point of 2 semi circles at their upper portion. the side will be 2ft

the area of intersection will be covered in the square.

area of intersection = 2*quarter area of circle of radius 2ft - area of square

= 2*(.25π4) - 4

2π-4 = 2.28

area of intersection = area not covered by semicircle

so area of shaded region = 4.56

Step-by-step explanation:

Answer:

  infinitely many

Step-by-step explanation:

Add 12-y to both sides of the second equation to put it into standard form like the first equation:

  y +(12 -y) = (x -12) +(12 -y)

  12 = x - y . . . simplify

  x - y = 12 . . . . second equation in standard form

We see this is identical to the first equation. That means every solution of the first equation is also a solution of the second equation. There are infinitely many solutions.

Answer:

x=13

Step-by-step explanation:

When you factor x^2-26x+169=0, you get (x-13)^2=0

When you solve that equation, you get x=13
