Reorder the following equations in ascending order of steepness: y= 15x + 5 y= 0.15x - 1 y=x y= x + 100
Gre4nikov [31]

Answer:

y= 0.15x - 1, y = x, y = x + 100, y = 15x + 5.

Step-by-step explanation:

When the slope of a line is less than 1 (if the slope is a decimal), the slope will not be steep. But when the slope is more than 1, the slope will be steeper than the average.

According to that rule, the steepest will be y = 15x + 5.

The next steepest equations will be y = x and y = x + 100 (they are both at the same degree of steepness; the intercept does not impact the steepness of the line).

The least steepest will bey = 0.15x - 1.

So, the order, from least steep to most steep, will be y= 0.15x - 1, y = x, y = x + 100, y = 15x + 5.

Hope this helps!

Find the MIDPOINT of the following two points:
xxMikexx [17]

Answer: (2.5  ;  1.5 )

Step-by-step explanation:

  • The midpoint of the segment with the points \bf  ( x_1  \ ;  \ y_ 1) and \bf (x_2 \  ;  \ y_2)  is calculated by the formula:

  • \bf (x _0  \ \ ;  \ \ y _0) = \bigg(\dfrac{x_1+x_2}{2} \ ; \  \dfrac{y_1+y_2}{2}  \bigg)  
  • Then :
  • \bf (x_0 \  ;  \ y_ 0)=\bigg( \dfrac{3+2}{2}  \ \ ;  \dfrac{4-1}{2}  \bigg)  =( 2.5  \  \ ; \ \  1,5 )

Part A: Factor x2y2 + 6xy2 + 8y2. Show your work. (4 points) Part B: Factor x2 + 8x + 16. Show your work. (3 points) Part C: Fac
skad [1K]

Answer:

Part A : y²(x + 2)(x + 4)

Part B: (x + 4) (x + 4)

Part C: (x + 4) (x - 4)

Step-by-step explanation:

Part A: Factor x²y²+ 6xy²+ 8y²

x²y²+ 6xy²+ 8y²

y² is very common across the quadratic equation , hence

= y² (x² + 6x + 8)

= (y²) (x² + 6x + 8)

= (y²) (x² + 2x +4x + 8)

= (y²) (x² + 2x)+(4x + 8)

= (y²) (x(x + 2)+ 4(x + 2))

= y²(x+2)(x+4)

Part B: Factor x² + 8x + 16

x² + 8x + 16

= x² + 4x + 4x + 16

= (x² + 4x) + (4x + 16)

= x( x + 4) + 4(x + 4)

= (x + 4) (x + 4)

Part C: Factor x² − 16

= x² − 16

= x² + 0x − 16

= x² + 4x - 4x - 16

= (x² + 4x) - (4x - 16)

= x (x + 4) - 4(x + 4)

= (x + 4) (x - 4)

Marley was asked to solve x2 - 4x + 9 = 0 using the Quadratic Formula. She found the discriminant first and decided she did not
saveliy_v [14]

We have been given Marley was asked to solve x^2-4x+9 = 0 using the Quadratic Formula. She found the discriminant first and decided she did not need to continue with the Quadratic Formula.

We are asked to determine whether Marley is correct or not.

We know when an equation is in form ax^2+bx+c=0, we can use discriminant to check for the real solutions of equation.

D=b^2-4(a)(c)

If D>0, then the equation will have two real solutions.

If D=0, then the equation will have one real solution.

If D, then the equation will have no real solutions.

Let us find discriminant.

a=1,b=-4\text { and }c=9

D=(-4)^2-4(1)(9)

D=16-36

D=-20

Since -20, therefore, the equation will have no real solutions, so Marley is correct.
