Helpp me please im lost

Answer:

m=2/13

Step-by-step explanation:

Given function:

Subtract middle value from both side:

Combine like terms:

Divide both sides by the same term:

Divide the terms:

Therefore, m=2/13.

Answer:

(1,5)

Step-by-step explanation:

Substitute the first equation into the second:

3x + 2(4x+1) = 13

3x + 8x + 2= 13

11x = 11

x = 1

y = 4(1) + 1 = 5

(1,5)

Answer:

B, for every y there are 150 x's

Answer:

1. [tex]y=\frac{2}{3}x-2[/tex]

2. [tex]y=\frac{-5}{4}x+5[/tex]

Step-by-step explanation:

all you are doing is solving for "y"

Answer:

ans 1. -2x = -6-3y

-2x = 9y

xy = -2/9

ans 2. 5x = 20 - 4y

5x = 16y

xy = 5/16

Answer:

The cross section of a pyramid that is perpendicular to the base will be a triangle.

Step-by-step explanation:

Answer:

3.37

Step-by-step explanation:

I am not very sure but this would be the answer.

Answer:

let X interchange y and vice versa

X= 2x+3

carry across +3

X-3=2X

carry across 2 (2X is 2 multiple by X when carried across the sign change to division)

so X-3 divided by 2 is = X

could be misinterpreting this question so I'm not entirely sure.

Answer:

C

1. homework

2. research outline

3. test

4. essay

Step-by-step explanation:

The tasks will be prioritized based on the ones with the closest date to today.

Her homework due tomorrow, therefore it is the first priority.

Her research outline due by the end of the week, therefore it is the second priority.

She has a test next week, and therefore it is the third priority.

Then finally, in 2 weeks, she has an essay and as such it should be the fourth priority.

The only option that has these tasks arranged in the correct order of priority based on the most important tasks as I have listed is Option C.

Answer:

I think it is the second one i am so so so sorry if it wrong

Step-by-step explanation:

Answer:

92°

Step-by-step explanation:

∠C=180-140=40

∠A+∠B+∠C=180

40+2X+X+2=180

X=46

∠B=46*2=92°

Answer: 92 degrees

Step-by-step explanation:

The exterior angle measuring 140 is equal to the sum of the two remote interior angles.

(X+2) + (2x) = 140. Combine like terms.

2 + 3x = 140. Subtract 2 from both sides.

3x = 138. Divide both sides by 3.

X = 46

Angle b = 2x. Substitute 46 in for x.

Angle b = 2(46)

Angle b = 92

Answer:

Its should be 1 because the graph shows you thats its 1

Answer:

f(x) = 19x/5+4

Step-by-step explanation:

f(0) = 4,f(5)=19

[f(x) - 4]/[x-0] = (19-0)/(5-0)

f(x) = 19x/5+4

Answer:

#3

Step-by-step explanation:

The line follows an inverted slope format, indicated by -2/3. Or down 2, and 3 to the right after going up by 4, creating the line. The other equations would flip the line horizontally because of a positive slope.

Step-by-step explanation:

Answer:

65

Step-by-step explanation:

2x + 25 + 25 = 180

2x + 50 = 180

2x = 180 - 50

2x = 130

2x / 2 = 130 / 2

x = 65

Answer:

3.6 D. decimal

Step-by-step explanation:

Answer:

#25: 0.023 < 22%

#29: 7/8, 0.88, 90%

Step-by-step explanation:

#25: Use this trick whenever converting decimals into percent. Move the decimal point two spaces to the right. Example: 0.01 = 1%

#29: Divide 7 by 8 for 7/8 and convert the decimal into a percent. Do the same with 0.88. Then just list these measures on a number line :D

Answer:

about 3.2 gallons. (3.2, 12)

Step-by-step explanation:

If gas costs $3.75 per gallon and Berto has $12, then he can purchase 12/3.75 gallons. This is approximately 3.2 gallons. So the coordinate on this line would be (3.2, 12)

about 3.2 gallons. (3.2, 12)

Answer:

1 + 8y + 28y² + 56y³ + 70[tex]y^{4}[/tex] + 56[tex]y^{5}[/tex] + 28[tex]y^{6}[/tex] + 8[tex]y^{7}[/tex] + [tex]y^{8}[/tex]

Step-by-step explanation:

For the expansion of [tex](1+y)^{8}[/tex]

Using the row of Pascal's triangle for n = 8 , that is the coefficients are

1  8  28  56  70  56  28  8  1

Decreasing powers of 1 from [tex]1^{8}[/tex] to [tex]1^{0}[/tex]

Increasing powers of y from [tex]y^{0}[/tex] to [tex]y^{8}[/tex]

Then

[tex](1+y)^{8}[/tex]

= 1 . [tex]1^{8}[/tex].[tex]y^{0}[/tex] + 8. [tex]1^{7}[/tex].[tex]y^{1}[/tex] + 28. [tex]1^{6}[/tex].y² + 56. [tex]1^{5}[/tex].y³ + 70.

= 1 + 8y + 28y² + 56y³ + 70[tex]y^{4}[/tex] + 56[tex]y^{5}[/tex] + 28[tex]y^{6}[/tex] + 8[tex]y^{7}[/tex] + [tex]y^{8}[/tex]

Answer:

The height of the tree is approximately 71.5 feet

Step-by-step explanation:

The given parameters are;

The angle of elevation to see the top pf the tree = 50°

The distance Peggy is laying from the base of the tree = 50 ft.

In order to answer the question using trigonometric ratio, we assume that the angle the tree makes with the ground is 90° that is the tree is perpendicular to the ground

Therefore, the line of sight to the top of the tree,  the height of the tree, and the distance from the base of the tree where Peggy is laying, forms a right triangle

Let, 's', represent the line of sight to the top of the tree, let 'h', represent the height of the tree, and let, 'd', represent the distance from the base of the tree where Peggy is laying

The third angle, θ, of the right triangle opposite 'd' is given by angle sum theorem of a triangle as follows;

θ = 180° - 90° - 50° = 40°

θ = 40°

By sine rule we have;

h/sin(50°) = d/(sin θ)

∴ h/sin(50°) = 60 ft./(sin 40°)

h = sin(50°) × 60 ft./(sin 40°) = 71.5052156 ft.

∴ The height of the tree, h ≈ 71.5 ft. by rounding to the nearest tenth

Step-by-step explanation:

Answer:

so practically, the only thing that we would do would be doing is converting the meters to feet 12.4 meters convert to feet would be 40.6 ft :)

Answer: To be exact, about 40.68241 feet, you can round to the nearest hundredths place to get 40.67

Answer:

32 Kilometers

Step-by-step explanation:

A Car travels 80 Kilometers in 2 and Half hours.

1 Hour =60 minutes, 2 & Half hours= 2.5*60= 150 minutes

Kilometers travelled by Car in a hour= 80/150*60= 32 Kilometers

Answer: you added 6 liters of juice

Step-by-step explanation:

You have 10 liters of a juice blend that is 60% juice. How many liters of pure juice need to be added in order to make a blend that is 75% juice?

Ten liters of a juice blend at 60% juice means you also have ten liters of a juice blend at 40% water. 10 x .40 yields 4 liters of water in your blend.

A juice blend of 75% has a water content of 25%. So the same 4 liters of water must represent 25% of the blend after adding more juice.

4/.25 = 16 liters. 16 x .75 = 12.

12 + 4 = 16.

That means after adding your juice you will have 16 liters of blend at 75% juice.

You originally had 10 liters at 60% and now you have 16 liters at 75% . Subtracting 10 from 16 means you added 6 liters of juice.
