4x(5-4y) distribute the 4x

4x(5) and 4x(-4y)

4*5=20 and dont forget the x, so its 20x

4*-4=-16 and dont forget the previous y and the x so its -16xy

Is the function given by, (Picture Provided)

Sever21 [200]

Answer:

a. yes

Step-by-step explanation:

The given function is

$f(x)=\left \{ {{3x-2,if\:x\le3} \atop {10-x,if\:x\:>\:3}} \right.$

$f(3)=\left \{ {{3(3)-2,if\:x\le3} \atop {10-3,if\:x\:>\:3}} \right.=7$

$\lim_{x \to 3^-} f(x)=3(3)-2=7$

$\lim_{x \to 3^+} f(x)=10-3=7$

$\Rightarrow \lim_{x \to 3} f(x)=7$

Since;

$\lim_{x \to 3} f(x)=f(3)$

The function is continuous at $x=3$

What is the center of the hyperbola?<br> (1,-2)<br> (1,1) (1,3)<br> (1,6)

Ahat [919]

Answer:

(1, 3)

Step-by-step explanation:

The center of a hyperbola can be found by looking at the midpoint between the two vertices.

Here, the two vertices are (1, 8) and (1, -2). We use the Midpoint Formula to figure out the vertex:

Midpoint is: $(\frac{1+1}{2} ,\frac{8+(-2)}{2} )=(\frac{2}{2} ,\frac{6}{2} )=(1,3)$

Thus, the answer is (1, 3).

Hope this helps!

Solve for x <br> 3x+4 = (2/5)x +2

julsineya [31]

Answer:-10/13

Step-by-step explanation:

3x+4 = (2/5)x + 2

First move the 4 to the other side by subtracting it.

it becomes : 3x = (2/5)x - 2

then multiply everything by 5 to get rid of the fraction.

it becomes 15x = 2x -10

then move the 2x to the other side by subtracting it.

you get 13x = -10

now you can divide everything by 13 to isolate the x.

and you get x = -10/13
