Find the slope and y-intercept of the line in each graph.

Answer:

0.441

Step-by-step explanation:

[tex](6.3 \times 10^3) \times (7 \times 10^{-5} ) \\ \\ = 6.3 \times 7 \times 10^3\times 10^{-5} \\ \\ = 44.1 \times {10}^{3 - 5} \\ \\ = 44.1 \times {10}^{ - 2} \\ \\ = 0.441 [/tex]

Answer:

y = -2x + 16

Step-by-step explanation:

So first you plug in the values you know into the slop int. form, equation, in which it is y = mx +b. When you plug in the slope value then you will get the equation of y = -2x +b, in which then you have to solve for the b value.

In order to solve for the b value, you then plug in the x and y values of the coordinate that is given so what you would do is this:  6 = -2(5) +b

                                                                                               6 = -10 +b

                                                                                                16 = b

So then you find out b is 16 in which you just plug back into the equation. So finally you write the equation, y = -2x+16.

Answer:

w= 2 3/4

Step-by-step explanation:

First, we need to find what can equal w. So, we can subtract 1/2 form both sides, so one sides has just w and one side has just a number. 3 1/4-1/2= 2 3/4. So w= 2 3/4

Answer:

2 3/4

Step-by-step explanation:

3 1/4 = 1/2 + w

Transfer 1/2 to other side

3 1/4 - 1/2 = w

Solve

w = 2 3/4

Answer:

Simplify: (4x2 - 2x) - (-5x2 - 8x).

Solution:

(4x2 - 2x) - (-5x2 - 8x)

= 4x2 - 2x + 5x2 + 8x.

= 4x2 + 5x2 - 2x + 8x.

= 9x2 + 6x.

= 3x(3x + 2).

Answer: 3x(3x + 2)

Answer:

61 is the rate at which the population changes every year

Step-by-step explanation:

Given

[tex]2000 - 61k = 48[/tex]

Required

Interpret 61

A linear equation has the form:

[tex]y = mk + b[/tex]

or

[tex]b + mk = y[/tex]

Where m is the rate

By comparison:

[tex]mk = -61k[/tex]

[tex]m = -61[/tex]

Hence, 61 represents the rate at which the population changes yearly.

The negative sign implies that the populatiin reduces

Answer:

The first option (the uppermost) is correct.

Step-by-step explanation:

When you multiply 1/2 by 3/4, you obtain the result of (1x3) / (2x4).

Simplifying, this gives us the result: 3/8, which is represented by the first choice.

Answer:

The inverse of x² +1 is:  

[tex]\sqrt{x-1},\:-\sqrt{x-1}[/tex]

Step-by-step explanation:

Given

y = x² + 1,  x>0

We know that A function g is the inverse of a function f if for y = f(x), x = g(y)

y = x² +1

Replace x with y

x = y² + 1

solve for y

y² = x - 1

Taking square root

[tex]y=\:\sqrt{x-1},-\sqrt{x-1}[/tex]

Thus, the inverse of x² +1 is:  

[tex]\sqrt{x-1},\:-\sqrt{x-1}[/tex]

Answer:

y intercept (-6,0), x-intercept (0,-8) : [tex]y = \frac{-4}{3}x -8[/tex]

y intercept (0,-6), x-intercept (-2,0): [tex]y = -3x -6[/tex]

y intercept (0,8), x-intercept (1.6,0): [tex]y = -5x + 8[/tex]

y intercept (0,7), x-intercept (-1.4,0): [tex]y = 5x + 7[/tex]

Step-by-step explanation:

y = mx + b

*note: b is the y intercept

1. y intercept (-6,0), x-intercept (0,-8)

[tex]m = \frac{-8 - 0}{0 - (-6)}= \frac{-8}{6} = \frac{-4}{3}\\y = \frac{-4}{3}x + b\\y = \frac{-4}{3}x -8[/tex]

2.y intercept (0,-6), x-intercept (-2,0)

[tex]m = \frac{0 - (-6)}{-2 - 0} = \frac{6}{-2} = -3\\y = -3x + b \\y = -3x -6[/tex]

3. y intercept (0,8), x-intercept (1.6,0)

[tex]m = \frac{0 - 8}{1.6 - 0}= \frac{-8}{1.6} = -5\\y = -5x + b\\y = -5x + 8[/tex]

4. y intercept (0,7), x-intercept (-1.4,0)

[tex]m = \frac{0 - 7}{-1.4 - 0} = \frac{-7}{-1.4}= 5 \\y = 5x + b\\y = 5x + 7[/tex]

Answer:

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

Step-by-step explanation:

To find slope using coordinates, use the formula above.

[tex](4, - 3) \: (0, - 2)→ \frac{ - 2 - ( - 3)}{0 - 4}→ \frac{ - 2 + 3}{ - 4} → - \frac{1}{4} [/tex]

Now, using the [tex]y = mx + b[/tex] formula, plug in [tex] - \frac{1}{4} [/tex] as [tex]m[/tex] (slope) and either coordinate as the [tex]x[/tex] and [tex]y[/tex] values. It looks like this:

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

To solve for [tex]b[/tex], continue to use PEMDAS.

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

Now use [tex]m[/tex] and [tex]b[/tex] to solve for your equation:

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

The answer is C.
