Answer:

y = 16

Step-by-step explanation:

y(y - 4) - (y - 2)(y - 3) = 10

Multiply/distribute.

(y² - 4y) - (y² - 5y + 6) = 10

Distribute negative symbol, rearrange.

y² - y² - 4y + 5y - 6 = 10

Combine like terms.

y - 6 = 10

Add 6 to both sides

y = 16

Answer:

(y {}^{2} - 4y) - ( {y}^{2} - 3y - 2y - 6) \\   - 4y - 3y - 2y - 6 \\  - 9y - 6 \: equals \: 10 \\  - 9y \: equals16 \\ y \: equals \:  \frac{16}{ - 9}

y = -(16/9)

If I triple four and subtract 2 each day how many days till I have zero
dangina [55]
Triple 4 is just 12
4X3=12
And so you can then divide by 2 because 2 each day(you could also just keep subtracting). Either way, you get 6 days

What's the midpoint of a line segment joining the points (5, –4) and (–13, 12)?
Vikki [24]

Answer:

The midpoint of the line segment is located at (-4, 4).

Step-by-step explanation:

We're given the coordinate points of a line that can help us find the midpoint.

The midpoint formula for a line is written as:

\bullet \ \ \ \displaystyle\big(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}\big)

Additionally, we are given the coordinate points (5, -4) and (-13, 12). We can use these and label them with the (x, y) system so we can substitute them into the formula.

In math, a coordinate pair is written as (x, y). This is where cos = x and sin = y. If we are given two coordinate pairs, we can label them with the (x, y) system but also incorporating a subscript to distinguish the two x-values from each other as well as the y-values. We do this by turning the two x-values into x₁ and x₂ and the y-values follow the same protocol: y₁ and y₂.

Therefore, we can label our two coordinates:

<u>(5, -4)</u>

  • x₁ = 5
  • y₁ = -4

<u>(-13, 12)</u>

  • x₂ = -13
  • y₂ = 12

Now, we can place these values into the midpoint formula and simplify to find our midpoint.

Recall that the midpoint formula is:

\bullet \ \ \ \displaystyle\big(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}\big)

Therefore, let's substitute these values.

\displaystyle\big(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}\big)\\\\\\\big(\frac{5 + (-13)}{2}, \frac{(-4)+12}{2}\big)\\\\\\\big(\frac{-8}{2}, \frac{8}{2}\big)\\\\\\\boxed{(-4, 4)}

Therefore, the midpoint of the line segment is located at (-4, 4), which is Option A.

!!!!!!!( help me solve this problem)!!!!!!!
ruslelena [56]
Hi Bre,

Since lines a and b are parallel, we know that in the image:
- ∡1 ⇔ ∡5
- ∡2 ⇔ ∡6
-       ...
- ∡4 ⇔ ∡8

We're given the angle of ∡7, which is 114°.  We can see that ∡7 + ∡8 will equal to 180° (since line b is a straight line) and since ∡8 ⇔ ∡4, we can deduct that ∡7 + ∡4 = 180°.

From here, it's just imputing the information and solving.
⇒ 114° + ∡4 = 180°
⇒ ∡4 = 180° - 114°
⇒ ∡4 = 66°

-Hope this helps!
