Which one is the right conversion?

The slope and intercept of the line 3x - 2y - 7 = 0 are -1.5 and -3.5 respectively

The equation of the line is given as:

3x- 2y - 7 = 0

Add 7 to both sides

3x - 2y = 7

Subtract 3x from both sides

-2y = -3x + 7

Divide both sides by -2

y = -1.5x -3.5

A linear equation is represented as:

y = mx  + c

Where m represents slope and c represents the intercept

By comparison;

m = -1.5 and c = -3.5

Hence, the slope and intercept of the line 3x - 2y - 7 = 0 are -1.5 and -3.5 respectively

Step-by-step explanation:

even numbers are numbers that can be equally split in half.

Example:

Hello, the answer should be [tex]m=\frac{6}{5}= 1,2[/tex].

First, let's edit the given function as [tex]y[/tex] parameter leave alone.

[tex]15x+18y=270\\\\18y=270-15x\\\\y=\frac{270-15x}{18}\\ \\y=\frac{270}{18}-\frac{15x}{18}[/tex]

If the given equation looks like;

[tex]y=f(x)\\\\y=ax+b[/tex]

then, the slope of the equation is the coefficient of [tex]x[/tex] parameter ([tex]a[/tex])

The slope(m);

[tex]m=\frac{-15}{18}=\frac{-5}{6}[/tex]

The product of the slopes of two perpendicular lines must be [tex]-1[/tex]. By that way, the slope of a line perpendicular to the given line is below:

The only key feature that these functions have in common is that they have the same y-intercept. So the correct option is D.

Here we have the functions:

[tex]f(x) = -x^2 + 2x + 1\\\\g(x) = 2^x[/tex]

f(x) is quadratic, and g(x) is exponential.

Notice that the exponential function has a positive base, so it is increasing. For the quadratic equation we can see a negative leading coefficient, so it opens downwards.  So first and second options are false.

Also, g(x) never intersects the x-axis, so third option is false.

Finally, the y-intercepts of the given functions are:

[tex]f(0) = -0^2 + 2*0 + 1 = 1\\\\g(0) = 2^0 = 1[/tex]

So the y-intercepts are equal, meaning that the correct option is D.

This proof was correctly started by both eric and maggie.

The next step in the proof is to set the right side of the equations equal.

This would be done by the transitive property of equality.

This refers to the use of inference to make an argument to show the logical conclusion to a set of assumptions.

Based on the given diagram that shows Triangle XYZ and the mathematical proof that both Eric and Maggie are trying to prove, they both give the correct proof and the next step was to make the right side of the equations equal.

The directrix of the parabola is [tex]y = \frac {-49}{16}[/tex]

The parabola equation is given as:

[tex]\frac 14(y + 3) = (x -2)^2[/tex]

A parabola is represented as:

[tex]4p(y - k) =(x -h)^2[/tex]

By comparing both equations, we have:

4p = 1/4 ==> p = 1/16

-k= 3 ==> k = -3

The directrix is represented as:

y = k - p

So, we have:

[tex]y = -3 - \frac 1{16}[/tex]

Take the LCM

[tex]y = \frac {-16 * 3- 1}{16}[/tex]

Evaluate

[tex]y = \frac {-49}{16}[/tex]

Hence, the directrix of the parabola is [tex]y = \frac {-49}{16}[/tex]

Using the linear equation, Miguel must work for 160 hours to receive $10,000 in total pay

Miguel works as a technician in a company. If his hourly rate and flat pay are $50 and $2000, how many hours must Miguel worked to receive $10,000 in total pay?

Let the number of hours be x and the total pay be y.

The equation that represents the total pay is represented as:

y = Rate * x + Base pay

From the question, we have:

Base pay = 2000

rate = 50.

So, we have:

10000 = 50 * x + 2000

Subtract 2000 from both sides

8000 = 50x

Divide both sides by 50

x = 160

Hence, Miguel must work for 160 hours
