Answer: 25

The problem is saying that f of x is equal to 13, which means you insert 13 for every x in the equation:

[tex]f(13) = 2(13) - 1[/tex]

Multiply 2 by 13 to get 26:

[tex]f(13) = 26 - 1[/tex]

Subtract 1 from 26 to get 25:

[tex]f(13) = 25[/tex]

rewrite in a slope-intercept form and graph ​

Answers

Answer:

[tex]y=\frac{3}{2}x+3[/tex]

Step-by-step explanation:

Take the given equation:

[tex]-3x+2y=6[/tex]

Solve for y so that the equation is written in slope-intercept form:

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

m is the slope and b is the y-intercept. x and y are the coordinate points (x,y).

Solve for y:

Add 3x to both sides of the equation:

[tex]-3x+3x+2y=6+3x\\\\2y=3x+6[/tex]

Divide both sides of the equation by 2 to isolate y:

[tex]\frac{2y}{2}=\frac{3x+6}{2} \\\\ y=\frac{3}{2}x+3[/tex]

The slope is [tex]\frac{3}{2}[/tex] and the y-intercept is 3.

To graph, you need two points. You can use the y-intercept as one.

The y-intercept is the place where the line crosses over the y-axis, where x equals 0, so the point is (0,3).

Next, take any value for x and insert it into the equation. We'll use 2:

[tex]y=\frac{3}{2}(2)+3[/tex]

Using this, you can solve for the value of y when x is equal to 2.

Simplify:

[tex]\frac{3}{2} *\frac{2}{1}=\frac{6}{2}=3 \\\\y=3+3\\\\y=6[/tex]

So, when x=2, y is 6 (2,6).

Plot the points (0,3) and (2,6)

Draw a straight line through the two, going past both.

3. Construct Arguments which is a better
approximation of V20, 4.5 or 4.47?
Explain.

Answers

Answer:

Step-by-step explanation:

Using the identity (x + 0.5)^2 = x(x + 1) + 0.25:

4.5^2 = 4 * 5 + 0.25 = 20.25

Also 4.45^2 = 19.8

so  4.47^2 will be closer to 20 than 4.5^2.

Answers

Answer:

x = 2

Step-by-step explanation:

Given

5x - 4 = - 3x + 12 ( add 3x to both sides )

8x - 4 = 12 ( add 4 to both sides )

8x = 16 ( divide both sides by 8 )

x = 2

Anna was driving east on a freeway at a constant velocity. She was 570 kilometers west of
her exit. In 2 hours, she drove one-third of the way to her exit. What was her velocity?

Answers

Answer:

Her velocity is 95 km/hour

Step-by-step explanation:

The given information includes;

The direction to which Anna was driving = Eastward

Her initial location on the journey = 570 kilometres west of her her exit

The distance she drove in 2 hours = 1/3 of the way to her exit

Therefore, the distance she drove in 2 hours = 1/3×570 = 190 m

Her velocity = Her distance covered/(The time it take to cover the distance)

Which gives;

Her velocity = (190 km)/(2 hours) = 95 km/hour

Her velocity = 95 km/hour.

Which statement describes how the graph of a function, h(x), and its inverse, h‒1(x), are related? The line y = ‒x is the perpendicular bisector of each segment connecting a point on h(x) to the corresponding point on h‒1(x). The line y = x is the perpendicular bisector of each segment connecting a point on h(x) to the corresponding point on h‒1(x). The graph of the inverse of h(x) is a reflection over the line y = 0 of the graph of h(x). The y-axis is the perpendicular bisector of each segment connecting a point on h(x) to the corresponding point on h‒1(x).

Answers

Answer:

Option B.

Step-by-step explanation:

We know that, if the graph of a function is reflected across the line y=x, then we get the graph of inverse of that function.

It means, the graph of inverse function is the mirror image of graph of function across the line y=x.

If h(x) is a function and h⁻¹(x) is its inverse function, then the line y = x is the perpendicular bisector of each segment connecting a point on h(x) to the corresponding point on h⁻¹(x).  

Therefore, the correct option is B.

Write this equation in slope-intercept form (y = mx + b).

Answers

Step-by-step explanation:

[tex]y-2=-3(x-4)\\\\y-2=-3x+12\\\\y-2+2=-3x+12+2\\\\\boxed{y=-3x+14}[/tex]

First distribute the -3 through the parenthses

which gives us y - 2 = -3x + 12.

Move the number to the right side of the equation

by adding 2 to both sides to get y = -3x + 14.

Notice that the equation above is written in slope-intercept form because

the y term is isolated or by itself on the left side of the equation.

20+3(7+4)+5+2(7+9)?????

Answers

Answer:

90

Step-by-step explanation:

Be sure to use PEMDAS. Begin with parentheses, the move to multiplication, then adding.

20 + 3(7 + 4) + 5 + 2(7+9)

20 + 3(11) + 5 + 2(16)

20 + 33 + 5 + 32

You can add those final four numbers in any order you want, to get a sum of 90.

Answer:

Your answer will be 90

Step-by-step explanation

First you will have to answer what's inside the parentheses

7 + 4 = 11 , 7 + 9 = 16

Then you multiply what is next to the parentheses

3×11 = 33, 2×16 = 32

Finally you will have to add

20 + 33 =53

53 + 5 =58

58 + 32 = 90

Evaluate the function.
[tex]f(x) = - x^{2} - 7x - 5[/tex]
Find
[tex]f( - 5)[/tex]

Answers

Answer:  5

===================================================

Explanation:

Everywhere you see an x, replace it with -5. Then use the order of operations PEMDAS to simplify

[tex]f(x) = -x^2 - 7x - 5\\\\f(-5) = -(-5)^2 - 7(-5) - 5\\\\f(-5) = -(25) - 7(-5) - 5\\\\f(-5) = -25 + 35 - 5\\\\f(-5) = 10 - 5\\\\f(-5) = 5\\\\[/tex]

Keep in mind that for the x^2 term, you are squaring all of x = -5, which includes the negative as well. So that means

x^2 = (-5)^2 = (-5)*(-5) = 25

but sticking a negative out front makes

-x^2 = -(-5)^2 = -25

Answers

Answer:

Step-by-step explanation:

We are told that the equation is for a 3 year debt, which is also the period over which the . This means that we can use the equation.

(I/175.393) + 0.663 = r

We are given r = 23.6%

Plugging this vakue in for r gives;

l/175.393 + 0.663 = 23.6

l/175.393 = 23.6 - 0.663

l/175.393 = 22.937

I = 175.393 x 22.937

I = $4022.99, which is approximately

Write the equation in standard form for the circle that has a diameter with endpoints (22,0) and (2,0)

Answers

Answer:

(x - 12)² + y² = 100

Step-by-step explanation:

The standard form of the equation of a circle is;

(x - a)² + (y - b)² = r²

where:

a and b are the coordinates of the centre of the circle

r is the radius

We are given the coordinates of the endpoints of the diameter as; (22,0) and (2,0)

Thus, the centre of the circle would be at the mid point of the endpoints of the diameter.

Coordinates of the centre is;

((22 + 2)/2), (0 +0)/2))

This is;

(12, 0)

So, a = 12 and b = 0

Now,to get the radius r, we will use the formula;

r = √[(x2 - x1)² + (y2 - y1)²]

Where;

(x1, y1) and (x2, y2) are 2 points namely (12,0) and (22, 0)

r = √[(12 - 22)² + (0 - 0)²]

r = √(-10)²

r = √100

r = 10

Thus,equation of the circle is;

(x - 12)² + (y - 0)² = 10²

(x - 12)² + y² = 100
