Answer:  option C.)   an 1.2 (n-1) -5  Sorry, no subscript for "a sub n"

Step-by-step explanation:

Substitute the values of n 1,2,3,4 and see if the output is the corresponding number in the sequence.

n = 1      2     3      4

   -5   -3.8  -2.6  -1.4

an=  1.2 (n-1) -5    the n-1 needs to be a number multiplied  by 1.2 produces a number added to -5 results in the number in the sequence.

a1=1.2(1-1) -5   a= 1.2(0) -5  a= -5

a2 1.2 (2-1) -5   a= 1.2(1) -5  a= -1.2 -5  a= -3.8

a3 1.2 (3-1) -5   a= 1.2(2) -5  a= -2.4 -5  a= -2.6

a4 1.2 (4-1) -5   a= 1.2(3) -5  a= -3.6 -5  a= -1.4

Answer:

x+3-12/8

Step-by-step explanation:

h(x)=-3/8x+12

y=h(x) let

y=-3/8x+12

here,

put at x at y and put y at x

x=-3/8y+12

8y=x+3-12

y=x+3-12/8

Answer:

Bike alone = 39

Step-by-step explanation:

Given that:

Total number = n(T) = 100

Jog= n(J)

Bike = n(B)

Bike and jog = n(BnJ) = 21

Number who jog = 46

Jog alone = 46 - 21 = 25

Neither jog nor bike = 15

Let bike alone = x

Hence,

Jog alone + bike alone + jog and bike + none of the two = 100

25 + x + 21 + 15 = 100

x = 39

Answer:

m∠RMS = 20°

Step-by-step explanation:

Find ∠RMS and look at the two values it crosses.

∠RMS crosses through 180 and 160.

Find the difference between the two values to get the measure:

180 - 160 = 20°

So, m∠RMS = 20°

(Its also an acute angle.)

Answer:

20

Step-by-step explanation:

The mistake is in using 160 as the answer. It isn't.

The angle is very small well under 90. It is acute.

The horizontal part of the angle is on 180 degrees of the protractor.

Therefore the angle size is 180 - 160 = 20 degrees.

Answer:

with what know question was there

Answer:

2.2 ounces.

Step-by-step explanation:

Quantity of peanuts Diana bought = 16.5 ounces

Quantity used for peanut brittle = 3/5

Hence:

3/5 × 16.5

= 9.9 ounces was used for peanut brittle.

The amount left =

16.5 ounces - 9.9 ounces

= 6.6 ounces.

We are told that: the next week, she split the remaining peanuts into 3 bags of trail mix for a hike with friends.

The ounces of peanuts she put in each bag of trail mix is calculated as:

6.6 ounces ÷ 3 bags

= 2.2 ounces.

Answer: y=8 m=5

Step-by-step explanation:

Answer:

1. 3.125

2. 4.5

Step-by-step explanation:

1. Since the figures are similar, the number you divide from one triangle to the other is the same, no matter the side length. 5(x) = 8 so 5/x = y. If x = 1.6, then y equals 3.125.

2. The same thing here. 4/x = 3 and 6/x = m. In the first equation x would be 1 1 1/3. 6/ 1 1/3 is the same as 6 x 3/4 which is 18/4 or 4.5.

Answer:

[tex]\boxed { m = -3}[/tex]

Step-by-step explanation:

Use the Slope Formula to help you find the slope of the two given points:

[tex]m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]

(where [tex](x_{1}, y_{1})[/tex] represents the first point and [tex](x_{2}, y_{2})[/tex] represents the second point)

-Apply the given points onto the formula:

[tex](x_{1}, y_{1}) = (3, 1)[/tex]

[tex](x_{2}, y_{2}) = (-2, 4)[/tex]

[tex]m = \frac{4 - 1}{-2 - 3}[/tex]

Solve for the slope:

[tex]m = \frac{4 - 1}{-2 - 3}[/tex]

[tex]m = \frac{3}{-1}[/tex]

[tex]\boxed { m = -3}[/tex]

Therefore, the slope is [tex]-3[/tex].

Answer:

B

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = [tex]\frac{1}{2}[/tex] and (a, b) = (4, 7) , thus

y - 7 = [tex]\frac{1}{2}[/tex](x - 4) → B

take out the square root of 543. 192

and secondly take out the cube root of same number which is given up

r = -189

-13 = r/9 + 8

Subtract 8 on both sides

-21 = r/9

Multply 9 on both sides

-189 = r

Answer:

r = -189

Step-by-step explanation:

-13 = r/9 + 8

-13 - 8 = r/9

-21 = r/9

-21 × 9 = r

-189 = r

Answer:

−32y+40

Step-by-step explanation:

=(−8)(4y+−5)

=(−8)(4y)+(−8)(−5)

=−32y+40

Answer:

-32y + 40

Step-by-step explanation:

Again, multiply -8 by terms inside the parenthesis.

-8x4=-32y and -8 x -5= 40

= -32y + 40

Answer:

9.472 kilograms

Step-by-step explanation:

Answer:

Option A. 55

Step-by-step explanation:

From the diagram given above, we discovered that the number of cubes in each stage is simply the addition of the squares of the number from 1 to the stage number i.e

1st Stage = 1² = 1 cube

2nd Stage = 1² + 2² = 1 + 4 = 5 cubes.

3rd Stage = 1² + 2² + 3² = 1 + 4 + 9

3rd stage = 14 cubes

With the above idea in mind, we can obtain the number of cubes in the 5th stage as illustrated below:

5th stage = 1² + 2² + 3² + 4² + 5²

5th stage = 1 + 4 + 9 + 16 + 25

5th stage = 55 cubes

Thus, there are 55 cubes in the 5th stage.

Answer:

This is not correct

Step-by-step explanation:

on the right side is 3.2 (x-5) this means that it represents 3.2 * (x-5). You have to multiply (according to the distributive property) 3.2 by x and 3.2 by (-5), so you get 3.2x + (3.2*-5) = 3.2x -16

The left side says 3.2x-5, that is clearly not equal to 3.2x-16.

It is impossible to say that there are infinitely many solutions as there are actually no possible solutions. Set the functions equal so it is:

3.2x-5 = 3.2x-16

solve for x by subtracting the 3.2x from the right side and the left side, then add 5 to both sides to isolate the variable with the other terms.

You get 0=11

That is not true.
