Step-by-step explanation:

=== [ -3(x-10)/4] + 2 = 11

==> [( -3x + 30 + 8)/4 = 11

==> -3x = 44 - 38

==> -3x = 6

==> -x = 6/3

==> x = -2

Answer:

x = -2

Step-by-step explanation:

\frac{-3(x-10)}{4} =9 (subtracted 2 from both sides)

-3(x-10) = 36 (multiplied both sides by 4)

x-10 = -12 (divided both sides by -3)

x=-2 (added 10 to both sides)

Find the length of a segment with endpoints Y(2, 8) and Z(- 2, 5) .
Andrej [43]

<em>The distance the length of a segment with endpoints Y(2, 8) and Z(-2, 5) is 5 units</em>

<h2>Explanation:</h2>

Endpoints of a Line segments are places where they end or stop. Line segments are named after their endpoints. In this case, those endpoints are Y and Z, so the line segment would be:

\overline{YZ} \ or \ \overline{ZY}

To find the length of this segment with endpoints Y(2, 8) and Z(-2, 5), let's use the Distance Formula:

d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}

Let's \ write: \\ \\ Y(x_{1},y_{1}) \rightarrow Y(2, 8) \\ \\ Z(x_{2},y_{2}) \rightarrow (-2, 5) \\ \\ \\ Substituting: \\ \\ d=\sqrt{(-2-2))^2+(5-8)}^2 \\ \\ d=\sqrt{(-4)^2+(-3)^2} \\ \\ d=\sqrt{16+9}  \\ \\ d=\sqrt{25} \\ \\ \boxed{d=5}

Finally, <em>the distance the length of a segment with endpoints Y(2, 8) and Z(-2, 5) is 5 units</em>

Choose the end behavior of the graph of each polynomial function
valentina_108 [34]

Answer:

  D, A, B

Step-by-step explanation:

The sign of the leading coefficient always tells you the end behavior on the right: positive = rises; negative = falls.

The degree of the polynomial tells you how the left- and right-end behaviors compare: even = they are the same; odd = they are opposites.

__

A) negative leading coefficient, even degree:

  • falls to the left, falls to the right (D)

__

B) positive leading coefficient, odd degree:

  • falls to the left, rises to the right (A)

__

C) negative leading coefficient, odd degree

  • rises to the left, falls to the right (B)

You have an allowance to spend on lunch this week. You will spend the same amount each day,and you get to keep whatever is left
Naily [24]

Answer:

The total allowance is $18.5, and the amount spent daily is $3.2

Step-by-step explanation:

let T and x represent the total allowance and the amount spent daily respectively.

It was started that the amount remaining after 2 days is $12.10 , which implies the person has spend an equal amount for 2 days

T - 2x =12.10       (equation 1)

It was started that the amount remaining after 5 days is $2.50  , which also implies the person has spend an equal amount for 5 days

T - 5x =2.5       (equation 2)

subtract equation 2 from 1

T - 2x -( T - 5x ) = 12.10 -2.5

T - 2x -T + 5x = 9.6

3x =9.6

Divide both side by 3

x = 9.6/3 =3.2

from equation 1

T - 2x =12.10  

T = 12.10 + 2x = 12.10 + 2*3.2

= 12.10 + 6.4 = 18.5
