lys-0071 [83]

Answer:

x=-5/2, x=3

Step-by-step explanation:2

2 * -15=-30

-6*5=-30

2x^2-6x+5x-15=0

2x(x-3)+5(x-3)=0

(2x+5)(x-3)=0

2x+5=0  x=-5/2

x-3=0  x=3

Mike and Danielle each improve their yards by planting hospice and shrubs. They bought their supplies from the same store. Mike
gizmo_the_mogwai [7]

Answer: each hospice costs $4 and each shrub costs $9

Step-by-step explanation:

Let x represent the cost of one hospice.

Let y represent the cost of one shrub.

Mike spent $71 on four hospice and seven Travis. This means that

4x + 7y = 71- - - - - - - - - - - - -1

Danielle spent $53 on 13 hospice and three shrubs. This means that

13x + 3y = 53- - - - - - - - - - - 2

Multiplying equation 1 by 13 and equation 2 by 4, it becomes

52x + 91y = 923

52x + 12y = 212

Subtracting, it becomes

79y = 711

y = 711/79

y = 9

Substituting y = 9 into equation 1, it becomes

4x + 7 × 9 = 71

4x + 63 = 71

4x = 71 - 63

4x = 8

x = 8/4 = 2

Question 1 of 10
il63 [147K]

Answer:

Ok, so it seems

erm

ok, even and odd

it is an odd one because the power is odd (3rd degree)

so then the ends go in different directions

and since leading coefient (5 in the 5x^3) is positive, it goes from bottom left to top right

so

A is false

B is false

C and D are true

answer is C and D

What is the solution set to the following equation?
motikmotik

The solution set of the equation x^2 + 2x - 48 = 0 is x = -1 ± 7

<h3>How to determine the solution set of the equation?</h3>

The equation is given as:

x^2 + 2x - 48 = 0

A quadratic equation is represented as:

ax^2 + bx + c = 0

By comparing both equations, we have

a = 1, b = 2 and c = -48

The solution of the quadratic equation is then calculated using

x = (-b ± √(b^2 - 4ac))/2a

Substitute values for a, b and c in the above equation

x = (-2 ± √(2^2 - 4 * 1 * -48))/2 * 1

This gives

x = (-2 ± √196)/2

Evaluate the square root of 196

x = (-2 ± 14)/2

Divide through by 2

x = -1 ± 7

Hence, the solution set of the equation x^2 + 2x - 48 = 0 is x = -1 ± 7
