A)S38
B) $65
C) S105
D) $303

Answer:

1.6 hours

Step-by-step explanation:

The two trains will be (75+85)=160 miles apart after each hour.

Therefore the time taken for the trains to be 256 miles apart would be 256/160 hours = 1.6 hours.

Answer:1,76,000 Profit

Step-by-step explanation:

Given

Jesse initially bought the car for 2,200,000 and sold it for 20 %

S.P.=C.P.(1+Profit%)

so, the Selling price of the car is S.P.=[tex]2,200,000\times 1.2=2,640,000[/tex]

profit=2,640,000-2,200,000=4,40,000

After this, he bought another car and sells it for a 10 % loss

So, the selling price of the car is [tex]2,640,000\times 0.9=2,376,000[/tex]

loss=2,640,000-2,376,000=2,64,000

Net Profit or loss=4,40,000-2,64,000=1,76,000 Profit

Answer:

B.

Step-by-step explanation:

So there is a pattern:

132-113=19

113-96=17

96-? is going to equal 15

So 96-81=15

And 81-68=13

Answer:

in order to determine the sign, we need to solve it first

lets collect the like terms by one side

x=41+2

x=43

so, the sign is positive

Organize the data from least to greatest

10, 10, 13, 14, 15, 15, 15, 20.15, 24, 25

Cross out data from each side until one point is left. So cross out one from one side, then another from the other side, continue this process until only one number is left. If two numbers are left, then take the average of the two numbers.

10, 10 , 13, 14, 15, 15, 20.15, 24, 25

10, 13, 14, 15, 15, 20.15, 24

Answer:

Step-by-step explanation:

From the given information:

We learned that it is possible that all entities can be in one of two states i.e. 0 or 1. Thus, all 5 entities can either be 0 or 1 (2 states).

∴

Number of outcomes = 2 × 2 × 2 × 2 × 2

= 2⁵

= 32

b)

All the outcomes of W = {(1, 1, x₃, x₄, x₅) (x₁, x₂, 1, 1, x₅) (1, x₂, 1, x₄, 1)}

Answer:

Y=4 when X =24

Step-by-step explanation:

If Y varies directly with X,  find Y when X=24, if Y = 5  when X= 30.​

We can write:

[tex]Y\:\alpha\: X\\Y=kX[/tex]

Where k is known as constant of proportionality

Now, we are given: Y = 5  when X= 30.​

We can find value of k

[tex]Y=kX\\5=k(30)\\k=\frac{5}{30}\\k=\frac{1}{6}[/tex]

Now, we will find Y when X = 24

and k=1/6

[tex]Y=kX\\Y=\frac{1}{6}(24)\\Y=4[/tex]

So, Y=4 when X =24.

Answer:

Step-by-step explanation:

Hey there!

y = -2x - 9

6x - 5y = -19

We're going to label the first equation as "1" and the second equation as "2." Now, in order to find the values of "x" & "y," we need to even out the equations by placing their "x" and "y" markers on the same side of the equal sign.

Let's start off by adding 2x to both sides of equation 1.

1) y + 2x = -2x - 9 + 2x

Simplify.

Equation 1 is now: 2x + y = -9

Now, we need to multiply equation 1 equations by "3" in order to create "6x" in both equations. This helps us find the value of "y" because it cancels out the "x" in both equations.

1) (2x + y = -9) × 3

Simplify.

1) 6x + 3y = -27

2) 6x - 5y = -19

Now that our equations are lined up, we can subtract equation 2 from equation 1.

Let's put this all together now.

8y = -8

Divide both sides by 8!

8y ÷ 8 = -8 ÷ 8

Simplify.

Now that we have the value of y, we can easily plug it into one of our equations to get our "x" value.

Equation 1: y = -2x - 9

Plug in "-1" for "y."

-1 = -2x - 9

Add 9 to both sides

-1 + 9 = -2x - 9 + 9

Simplify.

8 = -2x

Divide both sides by -2.

8 ÷ -2 = -2x ÷ -2

Simplify.

Therefore, x = -4 & y = -1

Hope this helped! :)

Answer:

x = - 4

y = - 1

Step-by-step explanation:

y = -2x - 9

2x + y = -9 (× 3)

6x - 5y = -19

______________

Elimination

6x + 3y = - 27

6x - 5y = - 19

____________ _

Solution for x :

Substitution

6x - 5y = -19

6x - 5(-1) = -19

6x + 5 = - 19

6x = - 19 - 5

6x = - 24

x = -24/6

6x - 5y = - 19

6(-4) - 5(-1) = - 19

-24 + 5 = - 19

-19 = - 19

Answer:

most likely C) 4.8 cm

Step-by-step explanation:

Answer:

y + 3 = -½(x - 1)

Step-by-step explanation:

Point-slope form equation is given as y - b = m(x - a), where,

m = slope, and (a, b) is a point the line passes through.

Given that the line is perpendicular to the y = 2x - 1, the slope (m) will be the negative reciprocal of 2, which is -½.

Thus, substitute m = -½, a = 1, and b = -3 into y - b = m(x - a).

Thus:

y - (-3) = -½(x - 1)

y + 3 = -½(x - 1)

Answer/Step-by-step explanation:

8 − 5 = 2 + 2 0 − 5 + 8 = 2 + 2 0

− 5 = 2 + 1 2

− 7 = 1 2

− 7 = 1 2 − 7 − 7 = 1 2 − 7

= − 1 2 7

Plug x = 4.3 into the equation given

ŷ = 2.6 − 3.1x

ŷ = 2.6 − 3.1(4.3)

ŷ = 2.6 − 13.33

ŷ = -10.73

Note: The symbol ŷ is read as "y hat". It's used to estimate the y value when it comes to regression equations.

Step-by-step explanation:

Divisor = -2n = -2 * 6 = - 12

Dividend = 3 + ( 4 * 6 - 6) = 3 + 18 = 21

Now

21 / -12

dividing numerator and denominator by 3

= - 7 / 4

Step-by-step explanation:

= -2n

= -2×6

= -12

again,

=3+(4n-n)

= 3+4×6-6

=3+24-6

=21

now,

= -12
