1) distribute -1/2
7x - 4x -2 = 6
2) combine like terms
3x - 2 = 6
3) use the addition properties of equality
3x = 8
4) use the division properties of equality
x = 8/3

Hi i have no idea does anyone have an idea ? please

Answer:

y = 2(x+5)²- 60

Step-by-step explanation:

f(x) = ax² +bx +c, is the standard form

f(x) = a(x - h)² +k , is the vertex form where the (h, k) is the vertex

y = 2x²+20x -10 ,

factor 2 from the two terms

y = 2(x² +10x) -10,

what perfect square has x² +10x? ... x²+10x +25 = (x+5)²

y = 2(x²+10x+25 )- 50 -10,

add 25 in parenthesis to get a perfect square yet subtract 2*25 = 50 so the equation will stay the same

y = 2(x+5)²- 60,

the equation has the vertex at (-5, -60)

According to the diagram, how far is point L from Rays KH and HF?Find the value of Y

RideAnS [48]

Answer:

The distance between L and the line KH and HF is;

$27$

The value of y is;

$y=9$

Explanation:

Given the figure in the attached image;

$\begin{gathered} KL=27 \\ KHL=(6y)^{\circ} \\ FHL=(4y+18)^{\circ} \end{gathered}$

From the image;

$KL=FL=27$

So, the distance between L and the line KH and HF is;

$27$

Also, the triangles KHL and FHL are congruent.

So, the angles KHL and FHL are congruent.

$m\measuredangle KHL\cong m\measuredangle FHL$

Substituting the expressions;

$\begin{gathered} (6y)^{\circ}=(4y+18)^{\circ} \\ 6y=4y+18 \\ 6y-4y=18 \\ 2y=18 \\ y=\frac{18}{2} \\ y=9 \end{gathered}$

Therefore, the value of y is;

$y=9$

James baked 5 1/4 dozen peanut butter cookies and 4 5/6 dozen oatmeal cookies for a bake sale what was the number of dozen cooki

Doss [256]

Answer:

$10\frac{1}{12}$ dozen

Step-by-step explanation:

$\frac{1}{4}$ × 3 = $\frac{3}{12}$

$\frac{5}{6}$ × 2 = $\frac{10}{12}$

$\frac{3}{12} + \frac{10}{12} = \frac{13}{12}$

$\frac{13}{12}$ is equal to $1\frac{1}{12}$

5 + 4 = 9 + $1\frac{1}{12}$ = $10\frac{1}{12}$ dozen
