y =3x + 14
2x - 3y = -14

Answers

Answer 1

The answer is.

y = 2, x = -4

Answer 2

Answer:

x=-4

Step-by-step explanation:

First substitute y=3x+14

2x-3(3x+14)=-14

Distribute:

2x-9x-42=-14

Add or subtract like terms

-7x-42=-14

-7x=28

Finally divide both sides by -7

-7x/-7=x

28/-7=(-4)

x=-4

If you deposit Tsh 4000 into an account paying 9% annual interest compound monthly ,low long until there is Tsh 10000 in the account?

Answers

Answer:

It will take 10.63 years.

Step-by-step explanation:

Giving the following information:

Present value (PV)= $4,000

Future Value (FV)= $10,000

Interest rate (i)= 9% annual compounded

To calculate the time required to reach $10,000, we need to use the following formula:

n= ln(FV/PV) / ln(1+i)  

n= number of years

n= ln(10,000 / 4,000) / ln(1.09)

n= 10.63

It will take 10.63 years.

Let's call the missing side ? as shown in the problem.

Now set up a equation where everything adds up to 28x+11

?+8x+2+8x+2+5x+12=28x+11

?+21x+16=28x+11

?=28x-21x+11-16

?=7x-5

So 7x-5 is the missing side!

Sara needs one third of a yard of ribbon to make a bow. She has 10 yards of ribbon. How many bows can she make?

Answers

Answer:

30 bows

Step-by-step explanation:

To find how many bows she can make, divide 10 by 1/3

10 / (1/3)

= 30

So, Sara can make 30 bows

Answer:

30

Step-by-step explanation:

If she needs just one third then she can make three ribbons out of a yard. so you multiply 3 by the number of yards she has so:

3 x 10 = 30

Step-by-step explanation:

VVV = πr²(hhh) = 36π(hhh)

The equation that represents the volume of the cylinder is 36πhhh m³.

What is a cylinder?

A cylinder is a three-dimensional object. It is a prism with a circular base.

volume of a cylinder = πr²h

The Beechcraft 1900D is a commuter airplane with a fuel capacity of 665 gallons. The function that represents how the amount of fuel changes as a function of distance flown is f(x)=−0.9x+665, where x represents miles flown, and f(x) represents the amount of fuel remaining. What is the rate of change for this scenario?

Answers

Given:

The  function that represents how the amount of fuel changes as a function of distance flown is

[tex]f(x)=-0.9x+665[/tex]

where x represents miles flown, and f(x) represents the amount of fuel remaining.

To find:

The rate of change for this scenario.

Solution:

The slope intercept form of a linear function is

[tex]y=mx+b[/tex]        ...(i)

Where, m is the slope or rate of change and b is the y-intercept.

We have,

[tex]f(x)=-0.9x+665[/tex]        ...(ii)

On comparing (i) and (ii), we get

[tex]m=-0.9[/tex]

Therefore, the rate of change for this scenario is -0.9. It means, the amount of fuel in the airplane is decreasing by 0.9 gallons per mile.

Help me plz help me plz

Answers

Answer:

A: 1 crackers = 95/4 cals

B: mass= 16/4

c: 15/4

A) 16 grams/4crackers will give the calories of one cracker; 16/4= 4 calories per cracker

B) we have 20 crackers per container so, first off you’ll calculate 20 divided by 4 and you’ll get 5 keep that aside and calculate the mass of 4 crackers which is already given as 16 grams. So 16x4= 64 and as what we kept aside was 5 so you’ll multiply 5 by 64= 320 grams. In order to get one cracker you’ll divide 320/20= which will give 16 grams.

C) it’s simply 15/4= 3.75 since each serving is 4 crackers. So on cracker has 3.75 calories from fat.

Find the measure of 14x+7+44+9x+3=180?​

Answers

61° is the measure of <STW

How to find the measure of <STW?

To solve this problem, we need some angle geometry knowledge

Given: <SRT = 44°, <RST = 9x+3, <RTW = 14x+7

<RTW = <SRT + <RST (exterior angle of a triangle is equal to the sum of opposite interior angles)

14x+7 = 44 + 9x+3

14x -9x = 44+3-7

5x = 40

x = 40/5 = 8

<STW + <RTW = 180 (sum of angles on a straight line)

<STW = 180 - <RTW

<STW = 180 - (14x+7)

Substitute x = 8:

<STW = 180 - (14(8) +7)

<STW = 180- 119 = 61°

Therefore, the measure of <STW is 61°

The width of a rectangle is the length minus 6 units the area of the rectangle is 27 units

Answers

Answer:

length = 9 units

Step-by-step explanation:

l = length

n - 6 = width

A = n(n - 6)

A = n² - 6n

27 = n² - 6n

n² - 6n - 27 = 0

(n + 3)(n - 9) = 0

n = -3, n = 9

length must be 9 because it cannot be a negative value
