Step-by-step explanation:

The solution of f(x)=g(x) to the nearest hundredth if f(x)= x^2-2 g(x) = x-1 is 1.62 or -0.62

Given the following function below:

f(x) = x^2 - 2
g(x) = x - 1

Since f(x) = g(x), hence;

x^2 - 2 = x - 1
x^2 - x - 1 = 0

Factorize to have:

x = 1/2 +√5/2  or x= 1/2 - √5/2

x = 1.62 or -0.62

Hence the solution of f(x)=g(x) to the nearest hundredth if f(x)= x^2-2 g(x) = x-1 is 1.62 or -0.62

-38×+43=-40×-57

-38×+43+40=-57

-38×+40×=-57-43

2×=-57+43

2×=-100

×=-50

I do not know if it's right

Given equation,

[tex] \\ \dashrightarrow \sf \qquad-38x+43=-40x-57 \\ \\ [/tex]

Adding 40x to both sides :

[tex] \\ { \dashrightarrow \sf \qquad-38x+43 + 40x=-40x-57 + 40x} \\ \\ [/tex]

[tex] { \dashrightarrow \sf \qquad2x+43=-57} \\ \\ [/tex]

Adding (-43) to both sides we get :

[tex] \\ { \dashrightarrow \sf \qquad2x+43 + ( - 43)=-57 + (- 43)} \\ \\ [/tex]

[tex] { \dashrightarrow \sf \qquad2x= - 100} \\ \\ [/tex]

Dividing 2 from both sides :

[tex] \\ { \dashrightarrow \sf \qquad \frac{2x}{2} = - \frac{100}{2} } \\ \\ [/tex]

[tex] { \dashrightarrow \tt \qquad \: x=-50} \\ \\ [/tex]

Answer:

1. Given the slope is 2, the equation now looks like y = 2x +b Given P (−1,4) we can solve for the b variable by substituting the x and y cordinates. 4 = 2 ⋅ (− 1) + b 4 = − 2 + b b = 6 Therefore the equation that has the slope of 2 and passes through the point (− 1,4) is y = 2x + 9 so it is d

2. i you can do that.

3. The equation for the slope of a line and the points also called point slope form of equation of a straight line is given by: y − y1 = m (x − x1) Whereas the slope-intercept form the equation of the line is given by: y = mx + b. Where b is the y-intercept.

4.In the formula,y = the y-coordinate of any point on the line,m = slope,x = the x-coordinate of any point on the line,and b = ...

Plug the slope and y-intercept into the formula. Remember,the slope is equal to the rise over the run.

Considering the vertex, the quadratic equation that models the path of the golf ball is given by:

y = -0.0011875(x - 400)² + 190

The equation of a quadratic function, of vertex (h,k), is given by:

y = a(x - h)² + k

In which a is the leading coefficient.

In this problem, the vertex is at the maximum height of the parabola, given by (400, 190), hence h = 400, k = 190, and:

y = a(x - 400)² + 190

It starts at the origin, that is, when x = 0, y = 0, hence:

0 = 400²a + 190

a = -190/400²

a = -0.0011875.

Hence, the equation is:

y = -0.0011875(x - 400)² + 190

The pairs of shoes increases as the time the cobbler works increases

The equation of the pairs of shoes is y = kx

The variation is a direct variation.

So, we  have:

y = kx

Where:

The cobbler can make 3 pairs of shoes in two hours,

So, we have:

k = 3/2

k = 1.5

Substitute k = 1.5 in y = kx

y = 1.5x

Hence, the equation of the scenario is y = kx

Answer:

Step-by-step explanation:

The profit he made from selling his hearing aids at a profit of 17% is $234.26.

To calculate the profit obtained, we must calculate how much money is equal to 17% of $1,378.

Based on the above, 17% of $1,378 equals $234.26. On the other hand, to calculate the final sale price of the earphone, we add the initial value plus the value of the profit.

$1,378 + $234.26 = $1,612.26

An equation is formed of two equal expressions. The ordered pair which is the solution of the system of linear equations is (0,2).

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The solution of the equation can be done in the following manner.

2x+3y=6

3x+5y=10

Let's take the first equation and find write it in terms of y. therefore, the first equation can be written as,

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

Now, substitute the value of x in the second equation,

[tex]3x+5y=10\\\\3(\dfrac{6-3y}{2})+5y=10\\\\18-9y +10y = 20\\\\-9y+10y=20-18\\\\y=2[/tex]

Thus, the value of y is 2. substituting the value of y in the first equation to get the value of x.

[tex]2x+3y=6\\\\2x+3(2)=6\\\\2x=6-6\\\\x=0[/tex]

Hence, the ordered pair which is the solution of the system of linear equations is (0,2).

The numbers given below that fall within the mean absolute deviation of the data are: C. 12,990, D. 12,705, E. 12720.

The mean absolute deviation is simply the average of the distance of each of the data points there are in a data distribution.

The difference of each data point from the mean is most likely within the same range with the mean absolute vallue.

If we subtract 12,990, 12,705, and 12720 from the mean of the data, 12,367, we would get a figure close to the mean absolute deviation, 350.

So the numbers that are within the mean absolute deviation are, C. 12,990, D. 12,705, E. 12720.

Answer:

Let x = the price of movies and let y = the price of video games

8x + 3y = 43

2x + 5y = 32

Use the Elimination Method by multiplying both sides of the second equation by 4

8x + 3y = 43

-(8x + 20y = 128)

-17y = -85

y = 5

2x + 5(5) = 32

2x + 25 = 32

2x = 7

x = 7/2 = 3.5

Movies cost $3.50 and video games cost $5
