So you know that all the angles in a triangle must add up to 180. Therefore, you can make this equation:

[tex](-20x+3)+(-40x+18)+(-15x+9)=180[/tex]

And now just solve for x!

[tex]-75x+30=180\\-75x=160\\x=\frac{160}{-75}\\x=-2.4[/tex]

So, your answer is:

x = -2.4

Answer:

a) 7z³+2z²-2z+1

b)2x²+3x-8

Step-by-step explanation:

a) (7z³+4z-1)+(2z²-6z+2)

   7z³+2z²-2z+1

b) (5x²-2x-1)-(3x²-5x+7)

   5x²-2x-1-3x²+5x-7

   2x²+3x-8

For the first one Answer:7z^3 −2z+1+2z^2

Step-by-step explanation:

(7z ^3

+ 4z −1)+(2z^2

− 6z +2)

Combine 4z and −6z to get −2z.

7z3  − 2z −1 + 2z2  +2

Add −1 and 2 to get 1.

7z3  − 2z + 1 + 2z2

Welcome

Answer: First we need to create an equation

x+x+2+x+4=156

3x+6=156

3x=156–6

3x=150

x=50

The answer is 50,52, and 54.

Check

50+(50+2)+(50+4)=156

50+52+54=156

Answer:

I got =

[tex]2 \ \frac{7}{9} [/tex]

Step-by-step explanation:

[tex] \frac{3(x - 2)}{4} + \frac{3(x - 3)}{8} = \frac{1}{2} [/tex]

[tex]6x - 12 + 3x - 9 = 4 \\ 9x - 21 = 4 \\ 9x = 25 \\ x = \frac{25}{9} = 2 \ \frac{7}{9} [/tex]

Answer:

5+(2/x)^1/2 This is the correct answer!!

Step-by-step explanation:

(i) The graph of f is symmetric about the y-axis - this is another way of saying f is an even function, which means

[tex]f(x) = f(-x) \iff \dfrac{ax+b}{x^2-c} = \dfrac{-ax+b}{x^2-c}[/tex]

The denominator remains unchanged, so

ax + b = -ax + b

Solve for a :

ax = -ax

2ax = 0

a = 0

(The alternative is that x = 0, but if that were the case then there would be infinitely many choices for a.)

So

[tex]f(x) = \dfrac{b}{x^2-c}[/tex]

(ii) Since

[tex]\displaystyle \lim_{x\to2^+}f(x) = +\infty[/tex]

it follows that x - 2 must be a factor of the denominator. If that's true, then

x ² - c = (x - 2) (x - r )

for some other root r of x ² - c. Expanding the right side gives

x ² - c = x ² - (2 + r )x + 2r

so that

-(2 + r ) = 0   ===>   r = -2

2r = -c   ===>   -c = -4   ===>   c = 4

and so

[tex]f(x) = \dfrac{b}{x^2-4}[/tex]

(iii) Finally, we're given that f ' (1) = -2. Differentiating f gives

[tex]f'(x) = -\dfrac{2bx}{(x^2-4)^2}[/tex]

so that

[tex]f'(1) = -\dfrac{2b}{(1^2-4)^2} = -\dfrac{2b}{9}[/tex]

Then

-2b/9 = -2   ===>   b = 9

and we find that

[tex]f(x) = \dfrac{9}{x^2-4}[/tex]

Answer:

A) 4

Multiply first cause it’s in the parentheses. To multiply fractions you go straight across

1/2 x 3/8

1 x 3 = 3

2 x 8 = 16

So you get

3/16

When dividing fractions you have to flip the second fraction and multiply the same.

So 3/4 divided by 3/16

Flip 3/16 to 16/3

So now

3/4 x 16/3

16 x 3 = 48

4 x 3 = 12

48/12

Simplified is 4

Step-by-step explanation:

A converse to a statement is switching the IF part with the THEN part.

Since the statement says  IF point B bisects the line, THEN B is the midpoint.

The converse would then say

IF B is the midpoint, THEN point B bisects the line.
