what is the first 5 terms of the sequence with a pattern of an = n2 + 4?

Answer:

Maggie =11

her brother= 34

Step-by-step explanation:

let the unknown be x

age of Maggie's brother: 4x-10

sum of their ages= 45

their ages=

4x-10+x =45

4x + x = 45 +10

5x = 55

x = 55/5

x= 11

age of maggie= 11

age of her brother = 4 × 11 - 10 = 34

Answer:

Maggie is 11 And Her Brother is 34

The equivalent value of the expression is y = ( 4x - 15 ) / 3

Given data ,

Let the equation be represented as A

Now , the value of A is

4x - 3y = 15

On simplifying the equation , we get

4x - 3y = 15

So , the left hand side of the equation is equated to the right hand side by the value of ( 15 )

Adding 3y on both sides , we get

3y + 15 = 4x

Subtracting 15 on both sides , we get

3y = 4x - 15

Divide by 3 on both sides , we get

y = ( 4x - 15 ) / 3

Therefore , the value of y = ( 4x - 15 ) / 3

Hence , the expression is y = ( 4x - 15 ) / 3

Answer:

Step-by-step explanation:

5 = 2/3 ( 8x - 6 )

to make it clearer, we can just interchange the position of LHS and RHS

2/3 ( 8x - 6 ) = 5

By transposing,

8x - 6 = 5 - 2/3

8x - 6 = 13/3

8x = 13/3 + 6

8x = 31 / 3

x = 31 / 3 × 1/8

x = 31 / 24

Answer:

27/16

Step-by-step explanation:

5=2/3(8x-6)

multiply 2/3 with 8x first then multiply 2/3 with -6

5=16/3x-4

shift 16/3x to the left hand side and bring 5 to the right hand side

-16/3x= -4+(-5)

-16/3x= -9

x= -9 divided by -16/3

Answer:

5/365 years, or 0.014 years

Step-by-step explanation:

Just like any conversion of units, we just set up the starting amount and multiply it by the correct ratio:

    5 days (1 year/ 365 days) = 5/365 years = 0.014 years

You just need to make sure you choose the right ratio. In this case, I know that 1 year is 365 days, and I'm trying to cancel the days unit, therefore I put the year in the numerator and the days in the denominator.

I hope this helps :D

Answer:

0.01

Step-by-step explanation: 5 ÷ 365 ( days of year)  and it gives you 0.013 then round to nearest  hundredth and since 3 is less than 5 it becomes a 0

Answer:

Josh's parent's house in Texas is the midpoint between South Carolina and California.

Step-by-step explanation

Let distance from South Carolina to California = D

D = 2,500 miles

Let distance from South Carolina to Josh's parent's house in Texas = D1

D1 = 12x - 106

Let distance from Josh's parent's house in Texas to California = D2

D2 = 5x + 685

Solve if Josh's parent's house in Texas is the midpoint between South Carolina and California

D1 = D2 = D/2

D/2 = 2,500 miles / 2

= 1,250 miles

D1 = D2 = 1,250 miles

D1 + D2 = D

Substituting D1 = 12x-106 and

D2 = 5x+685 and

D = 2,500

D1 + D2 = D

(12x-106) + (5x+685) = 2,500

Open parenthesis

12x - 106 + 5x + 685 = 2,500

Collecting like terms

12x + 5x = 2,500 - 685 + 106

17x = 1,921

Divide both sides by 17

x = 1,921 / 17

= 113

x = 113

Substitute x into D1 and D2

D1 = 12x - 106

D1 =12(113) - 106

= 1,356 - 106

D1 = 1,250

D2 = 5x + 685

D2 = 5(113) + 685

= 565 + 685

D2 = 1,250

Therefore, Josh's parent's house in Texas is the midpoint between South Carolina and California

Answer:

x < 6

Step-by-step explanation:

It has to be a number lower than 6, because 6+6 is 12 and that creates a balanced system.

It cant be a number higher than 6, because it will drag itself down.

So we need a number that when combined, it's sum will be lower than 12

Answer:

You can't factor x or any number other than 1 out.

Step-by-step explanation:

Answer:  

The answer is y=0.4

Answer:

Option B. y = 2x; 20 feet

Step-by-step explanation:

1. Determination of the equation that represents the relationship.

Let y be the distance travelled.

Let x be the time taken.

Let K be the speed.

From the question given above, the following data were obtained:

Distance (y) = 80 ft

Time (x) = 40 s

Speed (k) =.?

Speed = Distance /time

K = y/x ......... (1)

K = 80/40

K = 2 ft/s

Substitute the value of k into equation 1

K = y/x

K = 2 ft/s

2 = y/x

Cross multiply

y = 2x

Therefore, the equation that represents the relationship is y = 2x

2. Determination of the distance travelled in 10 s.

Speed (k) = 2 ft/s

Time (x) = 10 s

Distance (y) =.?

y = 2x

y = 2 × 10

y = 20 ft

Therefore, the person will travel 20 feet in 10 seconds.

From the above calculations, the right answer to the question is

Option B. y = 2x; 20 feet

Answer:

y=(-4/1)x-5

Step-by-step explanation:

You need to find the slope of the line and the y intercept, you can do this by plotting the points into a graph and figuring it out that way, or you can use the equations y2-y1/x2-x1 (for slope) and y=(*the slope from the other equation*)x+b. For both equations plug in a corresponding x and y coordinate given on the list (y1 and y2 would be consecutive coordinates, so 1 and 2, and same for x1 and x1, so -9 and -13). You should get (-4/1) for the slope, and when you plug that into the other equation you should get 5. Lastly you plug all these numbers into y=mx+b, and you get your answer.

Answer:

-95

Step-by-step explanation:

(4 - m) / 9 = 11

Multiply both sides by 9:

4 - m = 99

Subtract both sides by 4:

-m = 95

Multiply both sides by -1:

m = -95

Answer:

-63

Step-by-step explanation:

4 - M = 11

---

9

Bring the 4 to the opposite side of the variable ( bring the 4 to the other side of the = sign where it shows 11 or a different number with no variable. basically if you get a question problem for math like this, and when you see a variable aka a letter, move it to the other side where it doesn't have a letter, move it with the = sign then add or subtract. if the number that your moving away from the variable is positive, you subtract making it negative... but if you have a negative number, do adding instead. )

4 - 11 = -7

subtract and then you muliply

M

--- = -7

9

once you mulipled -7 x 9

your answer should be

M = -63

Answer:

1.6 cups every hour

Step-by-step explanation:

Given:

The measure of ∠2 is twelve less than five times the measure of ∠1.

∠1 and ∠2 form a linear pair.

To find:

The measure of ∠2.

Solution:

Let measure of ∠1 be x.

The measure of ∠2 is twelve less than five times the measure of ∠1.

[tex]m\angle 2=(5(m\angle 1)-12)^\circ[/tex]

[tex]m\angle 2=(5x-12)^\circ[/tex]

∠1 and ∠2 form a linear pair. So,

[tex]m\angle 1+m\angle 2=180^\circ[/tex]

[tex]x^\circ+(5x-12)^\circ=180^\circ[/tex]

[tex]6x-12=180[/tex]

[tex]6x=180+12[/tex]

[tex]6x=192[/tex]

Divide both sides by 6.

[tex]x=32[/tex]

Now,

[tex]m\angle 2=(5(32)-12)^\circ[/tex]

[tex]m\angle 2=(160-12)^\circ[/tex]

[tex]m\angle 2=148^\circ[/tex]

Therefore, the measure of angle 2 is 148 degrees.

Answer:

148 is the final answer
