What number is equivalent to 3/4 b-2/3 b =-9

1 answer:

5 0

Hi,

$b = - 9 \\ \frac{3}{4} \times b - \frac{2}{3} \\ 0.75 \times - 9 - 0.67 \\ - 6.75 - 0.67 = - 7.42$

Answer: -7.42

Hope this helps.

I have most of A like the x&y int and vertex I just need to know the equation in graphing form.

Serjik [45]

Step-by-step explanation:

a. $y = 2x^2 + 4x + 2\\y = (2x^2 +4x) +2\\y= 2(x^2+2x) + 2\\y = 2(x^2 +2x +1) + 2 - 2\\y = 2(x+1)^2 + 0\\(h,k) = (-1,0)$

b. $y = -x^2 +2x\\y = -(x^2-2x)\\y = -(x^2-2x+1)+1 \\y = -(x-1)^2+1\\(h,k) = (1,1)$

Given f(x) =

sergejj [24]

Answer:

Step-by-step explanation:

We are given the function:

$\displaystyle f(x) = \left\{ \begin{array}{ll} 2\cos(\pi x) \text{ for } x \leq -1 \\ \\ \displaystyle \frac{2}{\cos(\pi x)}\text{ for } x > -1 \end{array} \right.$

And we want to find:

$\displaystyle \lim_{x\to -1}f(x)$

So, we need to determine whether or not the limit exists. In other words, we will find the two one-sided limits.

Left-Hand Limit:

$\displaystyle \lim_{x\to-1^-}f(x)$

Since we are approaching from the left, we will use the first equation:

$\displaystyle =\lim_{x\to -1^-}2\cos(\pi x)$

By direct substitution:

$=2\cos(\pi (-1))=2\cos(-\pi)=2(-1)=-2$

Right-Hand Limit:

$\displaystyle \lim_{x\to -1^+}f(x)$

Since we are approaching from the right, we will use the second equation:

$=\displaystyle \lim_{x\to -1^+}\frac{2}{\cos(\pi x)}$

Direct substitution:

$\displaystyle =\frac{2}{\cos(\pi (-1))}=\frac{2}{\cos(-\pi)}=\frac{2}{(-1)}=-2$

So, we can see that:

$\displaystyle \displaystyle \lim_{x\to-1^-}f(x)=\displaystyle \lim_{x\to -1^+}f(x) =-2$

Since both the left- and right-hand limits exist and equal the same thing, we can conclude that:

$\displaystyle \lim_{x \to -1}f(x)=-2$

Our answer is A.

3 + 1/2 (3-x) < -7 Show work please!

x>23 is the correct answer. First you had to subtract by 3 from both sides of equation. And it gave us, $3+\frac{1}{2}(3-x)-3$ . Then simplify, and it gave us, $\frac{1}{2}(3-x)$ . Next, multiply by 2 from both sides of equation, and it gave us, $2*\frac{1}{2}(3-x)$ . Then simplify, and it gave us, $3-x$ . You can also subtract by 3 from both sides of equation, and it gave us, $3-x-3$ . Then simplify, and it gave us, $-x$ . Multiply by -1 from both sides of equation, and it gave us, $(-x)(-1)>(-23)(-1)$ . Finally simplify, and it gave us the answer is x>23 is the right answer. Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie
