(x+a)^2-(x-b)^2+x^2+(a-b)x-ab by (a+b)

Answers

Answer 1

Answer:

(a+b)(2x−ab+a−b)+x(a−b)+x²

Step-by-step explanation:

I can't make a good explanation, so here's a graph.

Also, this wouldn't be a proportional relationship because of exponents on the last term.

This is really a parabola.

(x+a)^2-(x-b)^2+x^2+(a-b)x-ab By (a+b)

Solve forx:
*
7(x + 5) = -35
O
x = -10
x = 5
O x = -5
X = 0

Answers

Answer: x = -10

Step-by-step explanation:

7 (x + 5) = -35

Distribute 7 to x + 5

7 * x = 7x

7 × 5= 35

7x + 35 = -35

Subtract both sides by 35

7x = - 70

Divide both sides by 7

x = -10

6. What is the vertex of the graph of y = x2 – 8x + 6
(Hint: use x = - to find the AOS)
b
2a
Show work

Answers

Answer:

[tex] \boxed {( 4, - 10)}[/tex]

Step-by-step explanation:

[tex]y = {x}^{2} - 8x + 6[/tex]

Here are some formulas that you might need.

[tex]h = - \frac{b}{2a} \\ k = \frac{4ac - {b}^{2} }{4a} [/tex]

The vertex of graph is at (h, k) from the vertex form.

[tex]x = h \\ y = k[/tex]

Substitute in the formula.

[tex]h = - \frac{( - 8)}{2(1)} \\ h = \frac{8}{2} \\ h = 4[/tex]

Next we find the value of k.

[tex]k = \frac{4(1)(6) - {( - 8)}^{2} }{4(1)} \\ k = \frac{24 - 64}{4} \\ k = \frac{ - 40}{4} \\ k = - 10[/tex]

Therefore the vertex is (4,-10).

Solve for the last missing side any way you'd like.

55°
10
35°
8.2

Answers

Answer:

12.2

Step-by-step explanation:

Let C be the last angle c + 55° + 35° = 180° (sum of angles in a triangle)

C + 90° = 180°

C = 180° - 90°

C = 90°

Let c be the last side

Using the sine rule a/sinA = b/sinB = c/sinC

Using any of the other two sides,

10/sin55° = c/sin90°

c = 10/sin55° × sin90°

c = 10/0.8192 × 1

c = 12.21

c ≅ 12.2

since x=10 you replace x in the equation with 10
so now you have 10+6
add those together and you get 16!

Solve for t in terms of the other variables.
k= 3tm + rs

Answers

Answer:

              [tex]t=\dfrac{k-rs}{3m}[/tex]

Step-by-step explanation:

It's like solving any equation, except we have letters instead of numbers .

k = 3tm + rs           {subtract rs from both sides}

k - rs = 3tm            {divide both sides by (3m)}

[tex]\dfrac{k-rs}{3m}=t[/tex]              {swap sides}

[tex]t=\dfrac{k-rs}{3m}[/tex]            m≠0    

{m must be ≠0 because  you cannot divide by 0. There is no t for m=0}

A translation of 2 units down ( negative y- direction ) means subtract 2 from the original y- coordinate.

Thus the translation rule is

(x, y ) → (x + 6, y - 2 )
