If AB = x+ 4, BC = 2x -10 and AC
lawyer [7]

Answer:

15

Step-by-step explanation:

By the diagram, you can see the sum of segment AB and segment BC is segment AC. Adding the given expressions for AB and B is 3x-6. Simplifying the equation 3x-6=2x+1, gives x=7. Substituting x=7 in the equation for segment AC gives 15.

Which of the following circumstances would likely make factoring the best method for solving a quadratic equation?
BabaBlast [244]

Answer:

The correct option is;

B. The difference of 2 perfect squares

Step-by-step explanation:

Solving a quadratic equation using factoring involves finding the factors of the equation that would yield the result of the quadratic equation

In order to find the roots of the quadratic equation, then the result of the factoring must be equal to zero, in which case, the constant terms in the factors are the solutions of the quadratic equation in opposite sign.

For example, we have;

x² - 5² = 11

We subtract 11 from both sides to get;

x² - 5² - 11  = 11 - 11

x² - 36 = 0

x² - 6² = 0

(x - 6) × (x + 6) = 0

Therefore, x = 6 or -6 which are the opposite sign of the constant terms in the factor.

Jon and Lexi are playing a marble game. According to their rules, 4 points are awarded for each red marble collected and 3 point
Fittoniya [83]
It would be 4r + 3b because If one red marble worth four points and blue marble worth 3 points each then we need to multiply the total number of marbles and calculate the sum. It would give the total number of points.

Write the equation of the line<br> perpendicular to y = *x+7 with a<br> y-intercept of (0-1)
I am Lyosha [343]

Answer:  y = -x - 1

<u>Step-by-step explanation:</u>

Use the Point-Slope formula: y - y_1=m_{\perp}(x-x_1)   where

  • (x₁ , y₁) is the given point (0, -1)
  • m_{\perp}\ \text{is the opposite reciprocal slope of the given line}\implies m_{\perp}=-1

Insert those values into the formula and solve for y:

y - (-1) = -1(x - 0)

y + 1 = -x

y      = -x - 1

Does the following represent direct variation? If yes, find the constant variation
svlad2 [7]

y/x =k

13/9 = 1.4444444

39/27=1.4444444

104/72=1.4444444

k =13/9  = 1 4/9

this is direct variation with a constant of 13/9 or 1  4/9
