Answer 1

Answer:

(3, 0)

Step-by-step explanation:

So with the 2 equations you can either choose which to start with but you need to make the X or Y the opposite from the other equation.

1.

3x + y = 9 (keep as is)
x + 2y = 3 --> -3( x + 2y = 3) In this case I chose to make the X the opposite of each other

--

3x - 3x = 0 (forced to get rid of)

y - 6y = -5y (Get the -6 by -3 x 2)

9 - 9 (Get the -9 by -3 x 3)

Left with:

-5y = 0 (Divide both sides by -5 to get X alone)

y = 0

----------------------------------------------------------

(Choose any ORIGINAL equation)

x + 2y = 3

x + 2(0) = 3 (substitute)

Left with:

x = 3  (x + 0 = 3)

-------------------------------------------------------------

Optional:

Chose the other equation (the opposite from above)

Substitute X and Y in 3x + y = 9

3(3) + (0) = 9

Left with: 9 = 9 (check)


Hope this helps!

Function represents a relationship between variables. The product of the two given functions (k·p)(x) is 2x³-8x²-7x+28.

What is Function?

A function assigns the value of each element of one set to the other specific element of another set.

Given to us

k(x) = 2x² − 7

p(x) = x − 4

As the two equations are given to us, k(x) and p(x), and we need to find (k ∘ p)(x), And we know the product of two functions can be written as,

[tex](k \cdot p)(x) = k(x) \cdot p(x)[/tex]

therefore,

[tex]k(x) \cdot p(x)\\\\= (2x^2-7)(x -4)\\\\= 2x^3 - 8x^2 - 7x +28[/tex]

Hence, the product of the two given functions (k·p)(x) is 2x³-8x²-7x+28.

Answer:

A = 228 ft²

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the height and b₁, b₂ the parallel bases

here h = 12 and b₁ = 14, b₂ = 24 , then

A = [tex]\frac{1}{2}[/tex] × 12 × (14 + 24) = 6 × 38 = 228 ft²

Answer:

The initial height is the y-intercept of the graph

slope of the graph = -2

Jordon interprets the only the slope correctly.

Aral interprets the only the initial height correctly.

Step-by-step explanation:

Slope = change in y ÷ change in x = (0 - 12) ÷ (6 - 0) = -12 ÷ 6 = -2

So the slope of the graph = -2

by inspection, the y-intercept = 12

Therefore, the equation for the line is   y = -2x + 12

Jordon interprets the only the slope correctly.

Marco puts his coins into stacks. Each stack has 10 coins.
He makes 17 stacks of quarters.
He makes 11 stacks of dimes.
He makes 8 stacks of nickels.
How much money does Marco have in his stacks of coins?

Answers

Answer:

Marco has $57.50 in total.

Step-by-step explanation:

17 x 10 = 170 quarters

170 x 0.25 = $42.50

11 x 10 = 110 dimes

110 x 0.10 = $11.00

8 x 10 = 80 nickels

A car requires 9 liters of gasoline to cover a distance of 108 km. If the car
spent 12.5 liters of gasoline, how far did the car travel?

Answers

Answer: 150km

Step-by-step explanation:

The question says that the car required 9 litres of gasoline to cover 108km which means we and then derive that:

9L = 108km

And we are trying to find out how much distance can cover:

12.5L =?

Therefore, in order to find out the distance, we need to figure out how much distance can 1L take the car

therefore:

1L = [tex]\frac{108km}{9L}[/tex] = 12km

So if we know how far 1L can take us, we can just multiply 12.5 litres by the 12km to find out the distance:

12.5L × 12km = 150km

So, therefore, 12.5 litres can cover 150km.

C: 18 2/3 Square Feet Per Hour

D: 27 Square Feet Per Hour.

Answers

Answer:

D. 27 square feet per hour

Step-by-step explanation:

Step 1:

Find the unit rate. Since 18 tiles are per 2/3 of an hour, we can divide 18 by 2 to get 9 tiles layed per third hour.

Step 2:

Multiply the 9 per third of an hour by 3 to find how many are per hour,

[tex]9*3=27[/tex] square feet per hour

Based on the graph given for f (x) construct the graph of f¹ (x). for f (x) find E, F and the formula of f (x) when it is known that it is a linear function.​

Answers

Answer:

To find an inverse function, reflect a graph of a function across the line y=x (and find the resulting equation)

To reflect a linear function in the line y=x, find points on f(x) and then swap their x and y coordinates.

Points on f(x):  (0, -4)  (2, 0)  (5, 6)

Points reflected in line y=x:  (-4, 0)  (0, 2)  (6, 5)

Plot points (-4, 0)  (0, 2)  (6, 5) and connect to form a straight line - this is the inverse of the function:  [tex]f^{-1}(x)[/tex]

To determine the equation of f(x):

Choose 2 points on f(x):  (5, 6) and (0, -4)

Calculate the slope (gradient) by using:

[tex]m=\dfrac{\triangle y}{\triangle x}=\dfrac{y_2-y_1}{x_2-x_1}=\frac{6--4}{5-0}=2[/tex]

Using the slope-intercept form:  y = mx + b

(where m is the slope and b is in the y-intercept)

From inspection of the graph, we can see the line crosses the y-axis at -4,

⇒ f(x) = 2x - 4

As the line is actually a line segment (with endpoints (0, -4) and (5, 6), then

f(x) = 2x - 4,   0 ≤ x ≤ 5

To determine the equation of [tex]f^{-1}(x)[/tex]:

Rewrite f(x)  as  [tex]y = 2x - 4[/tex]

Swap the x and y:  [tex]x = 2y - 4[/tex]

Rearrange to make y the subject: [tex]y= \dfrac{1}{2}(x + 4)[/tex]

Replace y with [tex]f^{-1}(x)[/tex]

So the equation of the inverse is:   [tex]f^{-1}(x)= \dfrac{1}{2}(x + 4)[/tex]

As the original function is a segment, then

[tex]f^{-1}(x)= \dfrac{1}{2}(x + 4), \ \ \ -4\leq x\leq 6[/tex]

(shown in blue on the attached diagram)

** I can't see any points labelled E and F on the original function. If they are the endpoints of the line segment of f(x), then they are (0, -4) and (5, 6) **

Answer:

  y = 130(24/13)^(x -10)

Step-by-step explanation:

The y-value changes by a factor of 240/130 = 24/13 for a unit change in the x-value. This means we can write the function as though it had an initial value of 130 and a growth factor of 24/13, translated 10 units to the right.

  y = 130(24/13)^(x -10)

_____

Additional comment

This can also be written in the form ...

  y = a·e^(kx)

where a=130·(24/13)^(-10) ≈ 0.28266, and k=ln(24/13) ≈ 0.61310

Where (h, k) is the center of the ellipse, 2a is the length of the major axis and 2b is the length of the minor axis.

∠ and ∠ are complementary angles. If ∠ = (12x - 3)° and ∠ = (7x - 2)°, find the
∠.

Answers

Answer:

57 °

Step-by-step explanation:

Complementary angles = 90 °

Since, Your angle don't have ∠ [  ] Then Let let "C" and "y"

Thurs, C = 12x- 3  and y = 7x - 2

It is given that angles r and s are complementary  angles. Two angles are complementary  if they add up to 90 degrees. This means the sum of measures of angle r and angle s must be 90 degrees. So,

c + y = 90

12x - 3 + 7x - 2 = 90

19x - 5 = 90

19x = 95

x = 95/19

x = 5

Using the value of x in expression or r, we get:

c = 12x - 3 = 12(5) - 3 = 60 -3 = 57 degrees.

So measure of angle c is 57 degrees.

Hence, the ∠ is 57 °

The y-intercept of g(x) is equal to 2 plus the y-intercept of f(x).

x    g(x)

−4    −10

−2 −    7

0        −4

2         1

The y-intercept is when x = 0.

So, we have:

g(0) = -4

Also, we have:

f(0) = -2(1.07)^0

f(0) = -2

-2 is greater than -4 by 2

Hence, the y-intercept of g(x) is equal to 2 plus the y-intercept of f(x).
