When the equation -3x − 5y = -5 is subtracted from -10x + 5y = -60, a third linear equation, -13x = -65, is formed, and it has a different solution from the original equations.

Answer:

D

Step-by-step explanation:

4+4=8 probability of success

4+4+3=11 total senario

therefore 8/11 is your probability of a success

A box of chocolates contains four milk chocolates, four dark chocolates, and three white chocolates. The probability that it is milk or dark chocolate is 8/11.

Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.

P(E) = Number of favorable outcomes / total number of outcomes

The total number of milk chocolate = 4

The total number of dark chocolate = 4

The total number of white chocolate = 3

The total number of milk or dark chocolate = 8

Total number of chocolate a box contains = 11

The probability that it is a milk or dark chocolate = 8/11

Answer:

The first option

Step-by-step explanation:

Adjacent angles are just two angles next to each other

Answer:

B=35+16t

Z=80+13t

15 weeks

Step-by-step explanation:

Let's start by writing our equations

B=35+16t

Z=80+13t

To figure out when they have the same amount we can set the equations equal to each other and solve for t

so we have

35+16t=80+13t

Subtract 13t and 35 from both sides to get

3t=45

Divide by 3 to get t=15

Answer:

there isn't a slope, because this line isn't even a function, because it is a vertical line... so it doesn't pass the vertical line test...

Step-by-step explanation:

Answer:

undefined

Step-by-step explanation:

the equation for the slope of the line is (y2-y1)/(x2-x1)

here are the given points: (-6,-8) and (-6,12)

label the points:

x1=-6

y1=-8

x2=-6

y2=12

now substitute into the equation (m is slope)

m=(12--8)/(-6--6)

m=(12+8)/(-6+6)

m=20/0

m=undefined

the slope is undefined because you cannot divide by 0

Answer:

x ≈ 38.7°

Step-by-step explanation:

Using the sine ratio in the right triangle

sinx = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{5}{8}[/tex] , then

x = [tex]sin^{-1}[/tex] ([tex]\frac{5}{8}[/tex] ) ≈ 38.7° ( to 1 dec. place )

Step-by-step explanation:

To write 0.87878787 as a fraction you have to write 0.87878787 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.

0.87878787 = 0.87878787/1 = 8.7878787/10 = 87.878787/100 = 878.78787/1000 = 8787.8787/10000 = 87878.787/100000 = 878787.87/1000000 = 8787878.7/10000000 = 87878787/100000000

And finally we have:

Answer:

x=−8

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−7(x+5)=21

(−7)(x)+(−7)(5)=21(Distribute)

−7x+−35=21

−7x−35=21

Step 2: Add 35 to both sides.

−7x−35+35=21+35

−7x=56

Step 3: Divide both sides by -7.

−7x/−7 = 56/−7

x=−8

Answer:-

Distributed: -7x+(-35)=21    Simplified: x=-8

Step-by-step explanation:-

Distributed:

-7(x+5)=21

(x*(-7))+(5*(-7))=21

-7x+(-35)=21

Simplified:

-7x-35=21

-7x=21+35

-7x=56

infinite solutions.

The number of solution the system of equations have infinitely many solutions.

A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.

The system of equations are y+2/3 x=4--------(I) and 2x=12-3y --------(II).

Here, a₁=2/3, b₁=1 and c₁=-4

a₂=2, b₂=3 and c₂=-12

Now,

a₁/a₂=b₁/b₂=c₁/c₂

2/6 =1/3=-4/-12

1/3=1/3=1/3

Infinitely many solutions

Therefore, the number of solution the system of equations have infinitely many solutions.

Answer:

Table for [tex]f(x)[/tex].

Step-by-step explanation:

The table offers a greater accuracy in comparison with graph, since any measure in the latter is subject to a margin of error associated with limitations of human sight, whereas any value can be either used directly from table, or estimated by linear interpolation on the assumption that curve is smooth, guaranteeing lower margins of error.

Answer:

Use an equation to determine whether f(x) or g(x) is the correct model. Create an equation for the radius of the flask in terms of its volume.

Because the height is the same as the radius, write this formula for the volume of the flask:

V= [tex]\frac{1}{3}[/tex][tex]\pi r^{3}[/tex]

Rewrite the formula, solving for r:

[tex]\frac{3V}{\pi } =r^{3}[/tex]

[tex]\sqrt[3]{\frac{3V}{\pi } } =r[/tex]

Now, graph the function and try to identify the values that are in the table.

The graph of the function does match the table of values. So, the table for f(x) can be used to find the radius of the flask. Notice that the graph for g(x) doesn’t match the graph of the formula, so exclude it as the answer.

This is the sample answer for edmentum/plato so you should change it a bit.

Answer:

Step-by-step explanation:

Given that:

[tex]r = 2.1x^2 - 14.3x + 35[/tex]

For year 2000; x = 0

So; [tex]r (0) = 2.1(0)^2 - 14.3(0) + 35[/tex]

[tex]r (0) = 35[/tex]

For year 2001; x = 1

[tex]r (1) = 2.1(1)^2 - 14.3(1) + 35[/tex]

[tex]r (1) =22.8[/tex]

For year 2002; x = 2

[tex]r (2) = 2.1(2)^2 - 14.3(2) + 35[/tex]

[tex]r (2) = 14.8[/tex]

For year 2003; x = 3

[tex]r (3) = 2.1(3)^2 - 14.3(3) + 35[/tex]

[tex]r (3) = 11[/tex]

For year 2005; x = 5

[tex]r (5) = 2.1(5)^2 - 14.3(5) + 35[/tex]

r(5) = 16

For year 2010; x = 10

[tex]r (10) = 2.1(10)^2 - 14.3(10) + 35[/tex]

[tex]r(10) = 102[/tex]

For year 2018; x =18

[tex]r(18) = 2.1(18)^2 - 14.3 (18) + 35[/tex]

[tex]r(18) = 458[/tex]

Thus, the table can be presented as seen below.

Year      2000     2001     2002     2003     2005     2010     2018

x               0             1             2            3           5            10         18

r(x)          35          22.8        14.8        11            16         102      458

SO, we will notice that the revenue for the albums starts decreasing and when it reaches the minimum, it started increasing with increasing x.

The attribute behind this trend is because the revenue function r(x) typically implies that it is a quadratic function.

-1/3 or -2/6

Step-by-step explanation:

First, you pick two points, I did (-5,10) and (1,8). Then, because slope is y(2)-y(1)/ x(2)-x(1), the equation would be 8-10/1-(-5) which equals -2/6 which simplifies into -1/3.

Answer:

11.7 cm

Step-by-step explanation:

Using Pythagoras Theorem

AC² = AB² + BC²

AB = 4 cm

BC = 11 cm

AC² = 4² + 11²

AC = √4² + 11²

AC =✓137

AC = 11.704699911 cm

Approximately = 11.7 cm
