7. If 1 || m and n || q, identify any of the following
angles congruent to 6

Answer:

The second graph

Step-by-step explanation:

Let's start with the top equation, 4y+3x=0

Isolate the y by moving the 3x to the other side. 4y=-3x

Divide both sides by 4 to fully isolate the y which will give you y=-3/4x

There's your first equation.

Then take 4y-x=16 and do the same thing

4y=16+x

y=4+x/4

y=x/4+4

Now you know that one equation is going to go left, or the negative direction, while the other will go right, or positive, meaning there will be a point where they intersect. So just basically look for the one where x/4+4 is rising while going right. Leaving you with either the 1st or 2nd graph.

Then,

Graph both using the rise/run method or just look for an answer choice where one of the equations is positive and intersects at y=4 (since the second equation is x/4+4) which makes it the second graph.

Let me know if you need any extra explanation

Answer:

(-4,3)

Step-by-step explanation:

To solve a system of equations by graphing, we'll need to graph both equations, and find their points of intersection.

Note that both equations are linear (no exponents, no radicals, no variables in a denominator, no variables multiplied to other variables, etc -- just numbers multiplied to a variable and added to other numbers multiplied to a variable).

To graph linear equations, often they are graphed by putting the equation in slope-intercept form.  Alternatively, since it is a line, two points can be found on the line, and then the line can be graphed.

Slope intercept form is [tex]y=mx+b[/tex], where "m" is the slope of the line, and "b" is the y-intercept (the place where the line crosses the y-axis).

To convert to slope intercept form, isolate "y".

First equation:

[tex]4y+3x=0[/tex]

[tex](4y+3x)-3x=(0)-3x[/tex]

[tex]4y=-3x[/tex]

[tex]\dfrac{4y}{4}=\dfrac{-3x}{4}[/tex]

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

Second equation:

[tex]4y-x=16[/tex]

[tex](4y-x)+x=(16)+x[/tex]

[tex]4y=x+16[/tex]

[tex]\frac{1}{4}*(4y)=\frac{1}{4}*(x+16)[/tex]

[tex]y=\frac{1}{4}*x+\frac{1}{4}*16[/tex]

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

To graph the lines, plot their y-intercepts first, then use their slopes to determine the rest of the line.

Recall that the slope is [tex]\frac{rise}{run}[/tex].

Once the equations are graphed, find the intersection from the diagram, (-4,3).

The equations currently are in an implicit form (a form where the variables aren't isolated, so neither variable is written in terms of the other).  To graph any line, find and plot two points, then draw the line between them.

To find points on the line, recall that the equation for a line relates the x-coordinate and y-coordinate through the equation.  So, if you want to find the y-coordinate for the line when the x-coordinate is 0, substitute 0 for x, and solve for y.  Often zero is used, because multiplying by zero cancel out the term, and makes the calculations easier.

Equation 1 - finding a point where x=0

[tex]4y+3x=0[/tex]

[tex]4y+3(0)=0[/tex]

[tex]4y+0=0[/tex]

[tex]4y=0[/tex]

[tex]\dfrac{4y}{4}=\dfrac{0}{4}[/tex]

[tex]y=0[/tex]

So, if x=0, then y=0.  So, the point (0,0) is on line 1.

To find another point, we need to choose another number.  As mentioned previously, often zero is used, and we could find a point on the line where the y-coordinate is zero.  However, since we just found that the point (0,0) is on the line, x=0 when y=0, and so y=0 when x=0.  We'll need a new number.

Another number that it often an easy choice mathematically is to choose the coefficient of the other variable.  So, for instance, in equation 1, the coefficient of the y term is "4", so let's choose the x-coordinate to be 4, and find the y-coordinate that goes with it:

Equation 1 - finding a second point, where x=4

[tex]4y+3x=0[/tex]

[tex]4y+3(4)=0[/tex]

[tex]4y+12=0[/tex]

[tex](4y+12)-12=(0)-12[/tex]

[tex]4y=-12[/tex]

[tex]\dfrac{4y}{4}=\dfrac{-12}{4}[/tex]

[tex]y=-3[/tex]

So, if x=4, then y=-3.  So, the point (4,-3) is also on line 1.

Those two points can be plotted, and the line drawn.

Equation 2 - finding a point where x=0

[tex]4y-x=16[/tex]

[tex]4y-(0)=16[/tex]

[tex]4y=16[/tex]

[tex]\dfrac{4y}{4}=\dfrac{16}{4}[/tex]

[tex]y=4[/tex]

So, if x=0, then y=4.  So, the point (0,4) is on line 2.

To find another point, this time, we can choose the y-coordinate to be zero, because we don't already know the x-coordinate that is associated with it.

Equation 2 - finding a second point, where y=0

[tex]4y-x=16[/tex]

[tex]4(0)-x=16[/tex]

[tex]0-x=16[/tex]

[tex]-x=16[/tex]

[tex]-1*(-x)=-1*(16)[/tex]

[tex]x=-16[/tex]

So, if y = 0, then x = -16.  So, the point (-16,0) is also on line 2.

Those two points can be plotted and the line drawn.  Once the lines are drawn, the intersection can be found.  From the diagram, the intersection is (-4,3).

Answer:

A

Step-by-step explanation:

[f(x) + g(x)]=x²+3x-6+1

=x2+3x-5

The value of the composite function is A: x² + 3x - 5.

Option A is the correct answer.

We have,

To find (f + g)(x), you simply need to add the two functions f(x) and g(x) together.

So, (f + g)(x) = f(x) + g(x).

Given:

f(x) = 3x + 1

g(x) = x² - 6

Now, add the two functions:

(f + g)(x) = (3x + 1) + (x² - 6)

Now, combine like terms:

(f + g)(x) = 3x + 1 + x² - 6

Finally, rearrange the terms in descending order of powers of x:

(f + g)(x) = x² + 3x - 5

Thus,

The value of the composite function is A: x² + 3x - 5.

Dilation are a kind of rigid transformations defined by the following formula:

P'(x, y) = O(x, y) + r · [P(x, y) - O(x, y)]     (1)

Where:

If we know that r = 2.5, O(x, y) = (0, 0), A(x, y) = (0, 0), B(x, y) = (0, 3), C(x, y) = (5, 3) and D(x, y) = (5, 0), then the resulting points are obtained:

A'(x, y) = (0, 0) + 2.5 · [(0, 0) - (0, 0)]

A'(x, y) = (0, 0)

B'(x, y) = (0, 0) + 2.5 · [(0, 3) - (0, 0)]

The coordinates for the center of the circle and the length of the radius are  ( -7, -1 ) and 6 respectively.

Option D) is the correct answer.

Given the equation;

x² + y² + 14x + 2y + 14 = 0

We subtract 14 from both sides

x² + y² + 14x + 2y + 14 - 14 = 0 -14

x² + y² + 14x + 2y = -14

Next, we complete the square for x² + 14

We have, ( x + 7 )² - 49

Next, we complete the square for y² + 2y

We have, ( y + 1)² - 1

We substitute these squares into the given equation

x² + y² + 14x + 2y = -14

( x + 7 )² - 49 + ( y + 1)² - 1 = -14

Collect like terms

( x + 7 )² + ( y + 1)² = -14 + 49 + 1

( x + 7 )² + ( y + 1)² = 36

( x + 7 )² + ( y + 1)² = 6²

Note that, the form of a circle is given as;

( x-h )² + ( y-k)² = r²

Hence, we match the values into the form and determine our center and radius.

( x-(+7) )² + ( y-(+1))² = 6²

( x-7 )² + ( y-1 )² = 6²

Hence Center = ( -7, -1 ) and radius = 6
