Answer:

x = 1 and y = 4

Step-by-step explanation:

Solution,

(x+2,y) = (3,4)

Now,

Comparing corresponding elements,

x+2 = 3 , y = 4

or, x = 3 - 2 , y = 4

or, x = 1 , y = 4

Therefore, the value of x is 1 and y is 4.

Find x.<br> 8x + 11<br> 12x - 1

ELEN [110]

Answer:

x = 3

Step-by-step explanation:

If T is the midpoint, that means segments ST and TU are congruent.

Step 1: Set up expression

8x + 11 = 12x - 1

Step 2: Solve

11 = 4x - 1

12 = 4x

x = 3

For what value of the constant c is the function fcontinuous on (−[infinity], [infinity])?

Arlecino [84]

Answer:

For $c=\frac{1}{7}$ the function f(x) is continuous on $(-\infty,\infty)$ .

Step-by-step explanation:

We have the following function

$f(x) = \left\{ \begin{array}{ll} cx^2+5x & \quad x$

For the function f(x) to be continuous on $(-\infty,\infty)$ it is sufficient to have continuity at x = 6, we need to ensure that as x approaches 6, the left and right limits match, this means that

$\lim_{x \to 6^{-} } f(x)=\lim_{x \to 6^{+} } f(x)=f(x)$ ,

which holds if and only if

$c\left(6\right)^2+5\left(6\right)=\left(6\right)^2-c\left(6\right)\\36c+30=36-6c\\42c=6$

namely if $c=\frac{1}{7}$ .
