If Mr. John plans to replace the carpet in his living room AND bedroom with carpet that cost $2.00 per square foot, how much will it cost to replace it if there are no other charges?

Answer:

x = 35°

Step-by-step explanation:

The three angles in a triangle add up to 180°.

The little square in the corner of one angle means that is a right angle and is 90°.

90° + 55° + x = 180°

145° + x = 180°

Subtract 145° from both sides.

x = 180° - 145°

x = 35°

Answer:

Yeah it is D you are correct but not C

[tex] \leadsto f( \rm x) = - {x}^{2} - 6x + 16[/tex]

[tex] \leadsto f( \rm x) = - {(x + 8)(x + 2)} \\ [/tex]

Function's domain is the set of values on which it is defined. One such function having domain x≥ 5 and range y ≤ 3 is: [tex]y = 3 - \sqrt{x-5}[/tex]

There can be actually infinite functions having same domain and range.

We need to find one function whose domain is x≥ 5 and range is y ≤ 3

Let the function be [tex]y = f(x)[/tex]

For keeping the function not defined for values of x < 5, we need to make such condition such that for values x < 5, the values of the function becomes undefined.

We can use some trick which keeps one sided interval undefined. One such function is the square root function which needs the input to be non-negative,

If we input x-5 to the square root function, then x can't go below 5, as square root of negative values is not defined(if not using complex numbers).

Thus, [tex]\sqrt{x-5}[/tex] is one part of f(x).

Next, we need the output to be limited by 3.

Since the quantity  [tex]\sqrt{x-5}[/tex]  is never negative, so 3 -  [tex]\sqrt{x-5}[/tex]  is never going to be bigger than 3.

Thus, [tex]y = 3 - \sqrt{x-5}[/tex] is one such needed function, having domain x≥ 5 and range y ≤ 3

Answer:

Their y-intercepts are equal

Step-by-step explanation:

The y-intercept is the y-value where the function crosses the y-axis. In this problem, functions are presented in 2 ways: algebraically and in a table.

1) Fortunately, the algebraic equation is written in slope-intercept form; this means that intercept is easy to find. The slope-intercept form is y=mx+b, where b is the y-intercept. In function 1, the b value is 10.

2) Another way to describe the y-intercept is the y-value when x=0. So, the y-intercept on a table is wherever the x-value is 0. In this case, the first row represents when x=0. The table says that when x=0, y=10. This means that the y-intercept for function 2 is 10.

Since the y-intercept for both of the functions is 10, it can be said that the 2 functions have equivalent y-intercepts.

Answer:

[tex]y=-\frac{1}{4}x - \frac{2}{3}[/tex]

Step-by-step explanation:

Hi there!

We are given the equation 3x + 12y = -8 and we want to convert it into slope-intercept form

The equation is currently in standard form, which is ax+by=c, where a, b, and c are free integer coefficients

Slope-intercept form is y=mx+b, where m is the slope and b is the y intercept

Notice that in standard form, the terms containing x and y are both on the same side, but in slope-intercept form, the expression is set equal to y (x is on the other side)

So first, we'll need to subtract 3x from both sides to remove it from the left side.

3x + 12y = -8

-3x            -3x

_______________

12y=-3x-8

Now divide both sides by 12, since we want to isolate y by itself (it's a bit like solving the equation for y)

12y=-3x-8

÷12   ÷12

___________

y=-3/12x -8/12

We can simplify the fractions to get:

[tex]y=-\frac{1}{4}x - \frac{2}{3}[/tex]

This is our final answer.
