Answer:

y = 1/2x + 10

Step-by-step explanation:

y = mx + b (slope intercept form equation)

-1/2x + y = 10

+1/2x         +1/2x (What you do to one side must be due to the other)

y = 10 + 1/2x or y = 1/2x + 10 (use to commutative property to swap the terms)

y = 1/2x + 10 (therefore this is in slope intercept form)

Answer:

R has to be -2

Step-by-step explanation:

So to find a slope the formula is written as

Y2-Y1/ X2 -X1

We know X1 and X2 and Y1.

If we plug those in and put Y2 as the variable ”r”

You’ll get

[tex]\frac{r-4}{1+5}[/tex]

Now make that equal to -1 since thats the slope

If you solve the equation it should get you -2

Answer:

[tex]Area = 6x^3+-5x^{2} +6x+5[/tex]

Step-by-step explanation:

Given that:

Length of a rectangle = [tex]3x^2-4x+5[/tex]

Width of rectangle = [tex]2x + 1[/tex]

To find:

Simple polynomial expression for finding the area of rectangle.

Solution:

First of all, we should know about the formula for finding the area of rectangle. Then we should know how to multiply two polynomials.

Formula for area of a rectangle in terms of its length and width is:

[tex]Area= Length \times Width[/tex]

Putting the given values:

[tex]Area = (3x^2-4x+5)(2x+1)[/tex]

Here, we can use the distributive property of multiplication for finding the value of the above multiplication expression.

[tex](A+B)\times (C+D) = A\times C + A\times D+ B\times C + B \times D[/tex]

Therefore, the multiplication of above polynomials can be written as:

[tex]Area = (3x^2-4x+5)(2x+1)\\\Rightarrow Area = 3x^2(2x+1)-4x(2x+1)+5(2x+1)\\\Rightarrow Area = 6x^3+3x^{2} -8x^{2} -4x+10x+5\\\Rightarrow Area = 6x^3+-5x^{2} +6x+5[/tex]

Therefore, the answer is:

[tex]Area = 6x^3+-5x^{2} +6x+5[/tex]

Answer:

420

Step-by-step explanation:

20 percent of 350 is 70, so adding that on will give us the price it is sold at for profit of 70 (20%).

Answer:

350 is our cost price and if we add our proft we get selling price

our profit=( 20/100)×350

i.e.70 so our profit is 70

then,

350+70= selling price

we get 420 as selling price

Step-by-step explanation:

g(r) = 25 - 3r

When r = 4, g(4) = 25 - 3(4) = 25 - 12 = 13.

Answer:

[tex]\boxed{\pink{\sf The\ required\ answer\ is\ 13 .}}[/tex]

Step-by-step explanation:

According to the Question , a function is given to us which is ,

[tex]\implies g(r) = 25 - 3r [/tex]

And we need to find the value of g(4) . So , substituting r = 4 , we have ;

[tex]\implies g(r) = 25 - 3r \\\\\implies g(4) = 25 - 3(4) \\\\ \implies g(4) = 25 - 12 \\\\\boxed{\red{\tt\implies g(4) = 13 }}[/tex]

Hence the required answer is 13.

Answer:

reflection across the x axis.

Step-by-step explanation:

When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x). the line y = -x is the point (-y, -x).

Also if u wanted me to be VERY specific as to what 12in cubed equals it would be 1728.

Answer:

C. (1,6)

Step-by-step explanation:

y=5x+1

y=x+5

x+5 = 5x+1

4x = 4

x = 1

y = 1 + 5 = 6

(x,y) = (1,6)

Answer:

The slide is approximately 12.75 feet.

Step-by-step explanation:

We know that Ruth is 5 feet tall, and her shadow is 3 feet tall.

5 ÷ 3 = 1.7 when rounded to the nearest tenth

Therefore, the shadow height of an object multiplied by 1.7 is the height of the actual object.

If the shadow of the slide is 7.5 feet, we need to multiply 7.5 by 1.7.

7.5 x 1.7 = 12.75

Therefore, the slide is approximately 12.75 feet.

Hope this helps! :D

Step-by-step explanation:

Step-by-step explanation:

(f o g)(x)

= f(x² - 5)

= 4(x² - 5) + 1

= 4x² - 19.

Therefore (f o g)(4) = 4(4)² - 19 = 64 - 19 = 45.

Answer:

[tex]\boxed {\boxed {\sf 45}}[/tex]

Step-by-step explanation:

When solving a composition of function composition, work from the inside to the outside.

We have the composition:

We must start on the inside, and find g(4) first.

1. g(4)

The function for g is:

[tex]g(x)=x^2-5[/tex]

Since we want to find g(4), we have to substitute 4 in for x.

[tex]g(4)=(4)^2-5[/tex]

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Addition, and Subtraction. First we should solve the exponent.

[tex]g(4)=16-5[/tex]

Subtract 5 from 16.

[tex]g(4)= 11[/tex]

Now, since g(4) equals 11, we have:

2. f(11)

The function for f is:

[tex]f(x)= 4x+1[/tex]

We want to find f(11), so substitute 11 in for x.

[tex]f(11)= 4(11)+1[/tex]

Solve according to PEMDAS and multiply first.

[tex]f(11)= 44+1[/tex]

Add.

[tex]f(11)= 45[/tex]

(f o g)(4) is equal to 45.

Answer:

x=-16

Step-by-step explanation:

−2(x+14)+1=5

Step 1: Simplify both sides of the equation.

−2(x+14)+1=5

(−2)(x)+(−2)(14)+1=5(Distribute)

−2x+−28+1=5

(−2x)+(−28+1)=5(Combine Like Terms)

−2x+−27=5

−2x−27=5

Step 2: Add 27 to both sides.

−2x−27+27=5+27

−2x=32

Step 3: Divide both sides by -2.

−2x

−2

=

32

−2

x=−16

Answer:

x=−16

Answer:

-2(x + 14) + 1 = 5

-2x - 28 + 1 = 5

-2x - 27 = 5

-2x = 32

x = -16

Step-by-step explanation:

y = x² - 16

x² = y + 16

x = sqrt(y + 16) as x is non-negative.

Therefore f^-1(x) = sqrt(x + 16). (A)

Answer:

Please find attached the graph of the quadratic function is created using Microsoft Excel

1) The line of symmetry is x = -1

2) The vertex is (-1, 2)

3) The y-intercept is (0, 1)

4) The domain is -∞ ≤ x ≤ ∞

5) The range is 2 ≥ y ≥ -∞

Step-by-step explanation:

The given equation is y = -x² - 2·x + 1

The general vertex form is y = a·(x - h)² + k

h = -b/(2·a) = 2/(-2) = -1

k = f(h) = -(-1)² - 2×(-1) + 1 = 2

Therefore;

1) The line of symmetry goes through the vertex and the line of symmetry is x = -1

2) The vertex = (h, k) = (-1, 2)

3) The y-intercept is the coordinate of the point where x = 0 which is  (0, 1)

4) The domain are the possible x-values, therefore, the domain = -∞ ≤ x ≤ ∞

5) The range is the possible values y-values.

From the graph, we have the range = 2 ≥ y ≥ -∞

The graph of the quadratic function is created using Microsoft Excel by generating y-values based on the equation and using the graphing function to insert a two dimensional graph of the generated combination of x and y values as shown in the attached figure.
