Answer:

x = -4 and y = 12

Step-by-step explanation:

Since you have y = -x + 8 you can substitute this into the first equation where y was so you have 3x + 4(-x + 8) = 36.

That way, there is only one variable and it is easier to solve.

3x + 4(-x + 8) = 36

3x -4x + 32 = 36

-x +32 = 36

-x = 4

x = -4

Plugging this into the equation y = -x +8,

y = -(-4) + 8

y = 4 + 8

y = 12

Answer:

b i am pretty sure

Step-by-step explanation:

Direction, displacement, and distance are the measurements are necessary for determining both the speed and velocity of a moving object

Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement.

The measurements which are necessary for determining both the speed and velocity of a moving object.

Speed=Distance/Time

To calculate speed we need to know the distance and time.

Velocity is the directional speed of an object in motion as an indication of its rate of change in position as observed from a particular frame of reference

Velocity=Displacement / Time

Hence  Direction, displacement, and distance are the measurements are necessary for determining both the speed and velocity of a moving object

1. Is decreasing so therefore is negative

2. Is undefined, Changed but is neither negative or positive

3. Is zero because it just stays the same

4. Is increasing therefore is positive

Hey there!

The answer is $48.44

We can solve this by first finding how much the discount is.

0.25 x 59.80

14.95

The amount of the discount is 14.95, so we then take the discount off.

59.80 - 14.95

44.85

Then, we find the amount of tax.

.08 x 44.85

3.588 (round to nearest cent = 3.59)

Then, add the price of the tax onto the price of the jeans.

3.59 + 44.85

48.44

Hope this helps! Good luck!

Answer:

2062 employees

Step-by-step explanation:

Basically, you have an exponential function going on here. If you start with 900 employees and add 5 percent to the amount of employees (multiply by 1.005) seventeen times, you will get the equation [tex]E=900*1.05^{17}[/tex]. If we round down (because there can not be a fraction of an employee), there will be 2062 employees after 17 years.

Answer:

x = 7

y = 2

Step-by-step explanation:

x² - y² = 45    

(x+y) (x-y) = 45

x + y = 9   (known)

9 x  (x-y) = 45

x - y = 5

y = x-5  

x + (x - 5) = 9  (substitute)

2x = 14

x = 7

y = 2

Answer:

a) [tex]f(n) = n^{2}[/tex]

[tex]f(1) = 1[/tex], [tex]f(2) = 4[/tex], [tex]f(3) = 9[/tex], [tex]f(4) = 16[/tex], [tex]f(5) = 25[/tex]

b) [tex]f(n) = n^{3}[/tex]

[tex]f(1) = 1[/tex], [tex]f(2) = 8[/tex], [tex]f(3) = 27[/tex], [tex]f(4) = 64[/tex], [tex]f(5) = 125[/tex]

c) [tex]f(n) = n^{2}+n^{3}[/tex]

[tex]f(1) = 2[/tex], [tex]f(2) = 12[/tex], [tex]f(3) = 36[/tex], [tex]f(4) = 80[/tex], [tex]f(5) = 150[/tex]

Step-by-step explanation:

This formulas uses only natural numbers, which means that [tex]n \ge 1[/tex]. Then, we evaluate each function at 1, 2, 3, 4 and 5:

a) [tex]f(n) = n^{2}[/tex]

[tex]f(1) = 1[/tex], [tex]f(2) = 4[/tex], [tex]f(3) = 9[/tex], [tex]f(4) = 16[/tex], [tex]f(5) = 25[/tex]

b) [tex]f(n) = n^{3}[/tex]

[tex]f(1) = 1[/tex], [tex]f(2) = 8[/tex], [tex]f(3) = 27[/tex], [tex]f(4) = 64[/tex], [tex]f(5) = 125[/tex]

c) [tex]f(n) = n^{2}+n^{3}[/tex]

In which each element is the sum of respective results found in a) and b).

[tex]f(1) = 2[/tex], [tex]f(2) = 12[/tex], [tex]f(3) = 36[/tex], [tex]f(4) = 80[/tex], [tex]f(5) = 150[/tex]

Step-by-step explanation:

Answer:

The answer is B

The numbers -2.23   [tex]-2\frac{2}{5}[/tex], and -0.95 are numbers that are less than -0.94 option (B) is correct.

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

We have a number list:

-15/16, 0.24, -2.23, 97%, [tex]-2\frac{2}{5}[/tex], -0.95

We can write these numbers such as:

-0.9375, 0.24, -2.23, 0.97, -2.4, -0.95

Now comparing the each number with -0.94

-0.9375 > -0.94

0.24 > -0.94

-2.23 < -0.94

0.97 > -0.94

[tex]-2\frac{2}{5}[/tex] or -2.4 < -0.94

-0.95 < -0.94

Thus, the numbers -2.23   [tex]-2\frac{2}{5}[/tex], and -0.95 are numbers that are less than -0.94 option (B) is correct.

Step-by-step explanation:

Answer:

3 friends played golf.

Step-by-step explanation:

Answer:

a) The building is 150 m tall

b) h(t)=-5(t+6)(t-5)

c) The stone hits the ground at 5 seconds.

Step-by-step explanation:

Function Models

The path of a stone thrown down from a tall building is modeled by the function:

[tex]h(t)=150-5t-5t^2[/tex]

Where h is the height in meters and t is the time in seconds after the stone is thrown.

a) To find the height of the building, we set t=0 because it's the moment when the stone is thrown and has the same height as the building:

[tex]h(0)=150-5*0-5*0^2[/tex]

[tex]h(0)=150[/tex]

The building is 150 m tall

b) The function is

[tex]h(t)=150-5t-5t^2[/tex]

Factoring out -5:

[tex]h(t)=-5(-30+t+t^2)[/tex]

Rearranging:

[tex]h(t)=-5(t^2+t-30)[/tex]

To factor the polynomial in parentheses, we must find two numbers whose product is -30 and sum is 1. We can also use the quadratic formula to find the roots and factor later.

These numbers are 6 and -5, thus the function is:

[tex]h(t)=-5(t+6)(t-5)[/tex]

c) The stone hits the ground when h=0:

[tex]-5(t+6)(t-5)=0[/tex]

The equation has two solutions:

t = -6

t = 5

The only feasible solution is t = 5, thus the stone hits the ground at 5 seconds.
