9 ÷  15 = 0.6

40 x 0.6 = 24

Check work:

9 x 0.6 = 15

24 x 0.6 = 40

Answer: -4

Work: So, to get -4, we need to simplify the equation. If you see any equation with +(- that's subtraction. So, with the rule, this equation is basically 8-12, and that's -4.

Answer:

-4

Step-by-step explanation:

8+(-12)

= 8-12

12-8=4

the answer is -4

Theoretical probability is a probability that is expected, for example when I flip a coin 100 times I expect tails to come up 50 times and heads to come up 50 times. The theoretical probability is 0.5 for a head.

Step-by-step explanation:

Answer:

Yes

Step-by-step explanation:

you substitute 4 for x and 5 for y.  

4 + 5 + z = 9

z = 0

so when you plug all of it together it equals 9.

Answer:

1) no, because a solution must be an ordered triple pair (x,y,z)

2) { x+y+z=5    

   { 2x-3y+z=7      

   { x+2y-4z=2

3) infinity many solutions

4) use equations (1) and (2) to eliminate y

5) solve one equation for one of its varaibles

Answer: 400 percent

Step-by-step explanation: 15 is the old value and 75 is the new value. In this case, we have a positive change (increase) of 400 percent because the new value is greater than the old value.

The best way to convert these into fractions is to multiply the decimal by what's in the denominator. Whatever number you get is what goes in the numerator.

1. For example, 0.6 x 10 = 6, hence the answer 6/10.

Even for ones like 8 where the decimal is 0.75, 0.75 x 4 = 3, which gives you 3/4.

Answer:

d=0; discriminant equals zero

this means there is one real root for the equation

Step-by-step explanation:

the discriminant is d=b^2-4ac

so we can write our equation in the format to subsitute

ax^2+bx+c=0

x^2 = 4x - 4

so...

1x^2 - 4x + 4 = 0

so

a= 1

b=-4

c=4

now subsitute

d= b^2-4ac

d= -4^2-4(1)(4)

d=16-16

d=0

The discrimant equals zero.

when the discriminant equal zero we know that there is one real root for the equation.

Answer:

9.72°

Step-by-step explanation:

Step one

Given data

let the hypotenuse be the distance the cyclist traveled = 6.5km

and let the opposite be the height of the mountain = 1.1 km

Step two:

Applying SOH CAH TOA

sin ∅= opp/hyp

∅= sin-1 opp/hyp

∅= sin-1 1.1/6.5

∅= sin-1 0.169

∅= sin-1 0.169

∅=9.72°

Answer:

$102

Step-by-step explanation:

$102 is your answer.

Step-by-step explanation:

Okay, so we know that in order to find this out we have to multiply. First, turn the percentage into a decimal, .15 . Then you're going to do .15 * 120.

.15 * 120 = 18.

Now, we have the cost of what will be taken away from the total bill. So , if $120 is the total bill, we will do $120 - 18 which will get us the answer of $102. So that's your answer! I hope this helps! Happy Holidays and stay safe! Best of luck on your work!

Answer:

The dimensions of the rectangle with the maximum area are 15 feet by 30 feet

Step-by-step explanation:

Optimization

There is a rectangle of dimensions x and y as seen in the figure below.

The side of length y is divided into three equal parts to make three equal rectangles.

The area of the greater rectangle is:

A = xy

It has to be maximized given the condition that the total perimeter including the middle dividers is 120 feet.

The outer perimeter of the rectangle is 2x+2y. There are two additional lines with a length of x feet each. Thus, the total perimeter is:

P = 2x + 2y + 2x = 4x + 2y

It has to be equal to 120 feet:

4x + 2y = 120

Dividing by 2:

2x + y = 60

Solving for y:

y = 60 - 2x

Substituting into the area:

[tex]A = x(60 - 2x) = 60x - 2x^2[/tex]

[tex]A=60x - 2x^2[/tex]

Taking the first derivative:

A'=60 - 4x

Equating to 0:

60 - 4x = 0

Solving for x:

x = 60/4 = 15

Thus x = 15 feet

Since y = 60 - 2x = 60 - 30 = 30

Thus y = 30 feet

The dimensions of the rectangle with the maximum area are 15 feet by 30 feet.

Answer:

Y = -x - 1

Step-by-step explanation:

Slope (rise / run) is -1 and the y-intercept is -1.

Equation for the graph below in terms of x is

[tex]y=-1x-1[/tex]

Given :

The graph of a line . we need to write equation for the line graph

'Equation of a line is in the form of [tex]y=mx+b[/tex]

where m is the slope and b is the y intercept

y intercept is the point where the graph crosses y axis

The graph crosses y axis at -1

so y intercept [tex]b=-1[/tex]

Now we find out slope . Lets pick two points from the graph

[tex](-1,0) and (0,-1)\\slope(m)=\frac{y_2-y_1}{x_2-x_1} =\frac{-1+0}{0+1}=-1[/tex]

slope m=-1  and b=-1

Substitute the slope and y intercept in y=mx+b
