Which is the equation of the line that passes through the points (-4, 8) and (1, 3)?

A. Y=x+4
B. Y=-x+12
C. Y=-x+4
D. Y=x+12

Positive,

because 2*12 equals to 24, and 24 is positive!

Answer:

Ernie has $10.50 saved.

Step-by-step explanation:

1.5 x $7 = 10.5

OR

(1 x $7) + (0.5 x $7) = $7 + $3.50 = $10.50

Hope this helps!

Answer:

Option A

Step-by-step explanation:

Both fractions have common denominators (x - 4). So, we can add the numerators.

[tex]\dfrac{x-9}{x-4}+\dfrac{x^{2}-x+5}{x-4}=\dfrac{x-9 +x^{2}-x +5}{x-4}\\\\\\=\dfrac{x -x +x^{2}-9+5}{x-4}\\\\\\=\dfrac{x^{2}-4}{x-4}[/tex]

Answer:

You find the range by subtracting the smallest value from the highest in the set. So in this case, it would be 5-0=0

[tex]\huge\boxed{\sf{b=55\:(b=y-intercept\:;)}}[/tex]

Step-by-step explanation:

Hello.

The y-intercept of a line is a point where the graph touches the y-axis.

Y-intercepts always have an x-coordinate of 0.

Now, what is the y-intercept?

If we have a point (0, b) then b is the y-intercept.

This is just a formula, so don't think that the y-intercept is b, okay?

The y-intercept is b, but only in formulae. :)

Using the formula, we can deduce that

the y-intercept is 55.

I hope it helps.

Have a great day.

Answer:

The slope-intercept form of a linear equation is y = mx + b. In the equation, x and y are the variables. The numbers m and b give the slope of the line (m) and the value of y when x is 0 (b). The value of y when x is 0 is called the y-intercept because (0,y) is the point at which the line crosses the y-axis.

Answer:

h = b - a

Step-by-step explanation:

Answer:

A/b = h

Step-by-step explanation:

A=bh

1) divide both sides by b

A/b = h

The required equation that can be used to figure out how many miles Hugh and his brothers have traveled based on the number of miles they have driven is y = 65x

Given the following variables

Time taken to travel is x

Mils traveled is y

Using the coordinate points (2, 130) and (4, 260)

The standard linear equation is y = mx + b

slope m = 260-130/4-2
m = 130/2

m = 65

For the intercept

130 = 65(2) + b

b = 0

The required equation that can be used to figure out how many miles Hugh and his brothers have traveled based on the number of miles they have driven is y = 65x

Answer:

-6 5/7

Multiply the denominator by the number that doesn't exceed -47. Here, it would be -6.

7 x (-6) = -42

Then, subtract the difference to get the mixed number.

-42-5 = -47

The numbers used are found in the improper fraction: -6 5/7

Answer:

[tex]-6\frac{5}{7}[/tex]

Step-by-step explanation:

Given the following question:

[tex]-\frac{47}{7}[/tex]

To convert an improper fraction into a mixed number we simply have to divide the numerator by the denominator.

[tex]-\frac{47}{7}[/tex]
[tex]-\frac{47}{7}=47\div7=-6\frac{5}{7}[/tex]
[tex]=-6\frac{5}{7}[/tex]

Let 6 represent how many times 7 does into 47
Let 5 represent the remainder
Let 7 represent the denominator which remains the same.

Hope this helps.

Step-by-step explanation:

the usual line equation is

y = mx + b

I personally rather write it

y = ax + b

but really, all letters are possible as needed (particularly, if certain letters are already used for other parts of the problem definition).

what is important is to understand the messaging of the parts of such equations independently of what letter is used for what.

the factor of x (usually m in these equations) is the slope of the line, its incline. it is expressed as the ratio "y coordinate change / x coordinate change" when going from one point on the line to another.

the constant term (often called b in these equations) is the y-intercept (the y value when x = 0, indicating where the line is intercepting the y-axis).

I guess the equation in your problem actually looks like

2 + 3x + 5 - 2x = y

so, let's combine similar terms

3x - 2x + 2 + 5 = y

x + 7 = y

and now compare this to the general line equation, and we find

m = 1

b = 7

Answer:

The answer is 55.

m=55

Step-by-step explanation:

we know that a straight line is 180
We know that m+125 is a straight line.
This means that we will subtract 125 from 180
When you do that, you get 55.

We can check our answer by doing 125+55
That will get you 180.

In hexadecimal/base-16, we have B₁₆ = 11, C₁₆ = 12, and D₁₆ = 13, so

4D₁₆ = 4 × 16¹ + 13 × 16⁰ = 77

and

BC2₁₆ = 11 × 16² + 12 × 16¹ + 2 × 16⁰ = 3010

Answer:

10/11

Step-by-step explanation:

Decompose each given F(s) into partial fractions.

[tex]F(s) = \dfrac{s+1}{s(s-1)(s-3)}[/tex]

has partial fraction decomposition

[tex]\dfrac{s+1}{s(s-1)(s-3)} = \dfrac as + \dfrac b{s-1} + \dfrac c{s-3}[/tex]

Combine the rational terms on the right and solve for the coefficients:

[tex]\dfrac{s+1}{s(s-1)(s-3)} = \dfrac{a(s-1)(s-3) + b s(s-3) + c s(s-1)}{s (s-1) (s-3)}[/tex]

[tex]1 = a(s-1)(s-3) + bs(s-3) + c s(s-1)[/tex]

[tex]1 = 3 a + (-4 a - 3 b - c) s + (a + b + c) s^2[/tex]

[tex]\begin{cases}3a=1 \\ -4a-3b-c = 0 \\ a+b+c=0 \end{cases} \implies a=\dfrac13, b=-\dfrac12, c=\dfrac16[/tex]

Then

[tex]F(s) = \dfrac13 \times \dfrac1s - \dfrac12 \times \dfrac1{s-1} + \dfrac16 \times \dfrac1{s-3}[/tex]

Using the frequency-shifting property, the inverse transform is

[tex]\boxed{f(t) = \dfrac13 - \dfrac{e^t}2 + \dfrac{e^{3t}}6}[/tex]

The other transform can be dealt with in the same manner.

[tex]F(s) = \dfrac1{(s-1)(s-2)(s-3)} = \dfrac a{s-1} + \dfrac b{s-2} + \dfrac c{s-3}[/tex]

[tex]\implies 1 = a(s-2)(s-3) + b(s-1)(s-3) + c(s-1)(s-2)[/tex]

[tex]\implies 1 = 6 a + 3 b + 2 c + (-5 a - 4 b - 3 c) s + (a + b + c) s^2[/tex]

[tex]\implies \begin{cases}6 a + 3 b + 2 c=1 \\ -5a-4b-3c = 0 \\ a+b+c=0\end{cases} \implies a=\dfrac12, b=-1, c=\dfrac12[/tex]

[tex]\implies F(s) = \dfrac12 \times \dfrac1{s-1} - \dfrac1{s-2} + \dfrac12 \times \dfrac1{s-3}[/tex]

[tex]\implies \boxed{f(t) = \dfrac{e^t}2 - e^{2t} + \dfrac{e^{3t}}2}[/tex]
