Answer:

- 13

Step-by-step explanation:

\begin{gathered}y = 2 - 5x \\ f(x) = 2 - 5x \\ f(3) = 2 - 5(3) \\ f(3) = 2 - 15 = - 13\end{gathered}

y=2−5x

f(x)=2−5x

f(3)=2−5(3)

f(3)=2−15 = −13

Answer:

length of rope [tex](P+3) =12.167[/tex]

Step-by-step explanation:

From the question we are told that

Length of rope on Ground [tex]L_1=3 feet[/tex]

Length of rope from pole base when stretched [tex]L_2=8feet[/tex]

Given length of pole as P

length of the rope is therefore given by

[tex]P+3[/tex]

Generally the Pythagoras theorem is mathematically given by

[tex]P^2+8^2=(P+3)^2[/tex]

[tex]P^2+64=P^2+9[/tex]

[tex]P=9.167[/tex]

Therefore

length of rope [tex]P=9.167[/tex]

length of rope [tex](P+3) =9.167+3[/tex]

length of rope [tex](P+3) =12.167[/tex]

Answer:

Number of batches of cookies = 4

Number of batches of brownies = 7

Step-by-step explanation:

Let the number of batches of cookies she made = x

And the number of batches of brownies = y

Total number of batches she made = 11

So the equation representing batches will be,

x + y = 11 ---------(1)

Her recipe for cookies calls for eggs = 1 per batch

So eggs required for x batches of cookies = 1 × x = x

Similarly, her recipe for brownies calls for eggs = 2 per batch

So, eggs required for y batches of brownies = 2y

Total number of eggs required = 18

Therefore, equation will be,

x + 2y = 18 ---------- (2)

Equation (2) minus equation (1)

(x + 2y) - (x + y) = 18 - 11

y = 7

From equation (1),

x + 7 = 11

x = 4

Therefore, number of batches of cookies and brownies she made were 4 and 7.

Answer:

Step-by-step explanation:

1 foot = 12 inches

47.5 inches × (1 foot)/(12 inches) = (47.5/12) feet

24 boards × ((47.5/12) feet)/board = 95 feet

:::::

(8 feet)/board × (12 inches)/foot = (96 inches)/board

96/47.5 = 2 remainder 1

An 8-foot board provides two 47.5" boards, with an inch wasted.

He needs to buy 12 of the 8-foot boards.

Answer:

[tex](x-5)-(x-1)=-4[/tex]

[tex]=2x-4[/tex]

[tex](x-5)+(x+1)=-6[/tex]

[tex](x-5)+(x-1)=2x-6[/tex]

Step-by-step explanation:

In each of the expressions we first need to open the brackets and change the sign according to the sign preceding the bracket. After that we perform simple arithmetic to find the result.

[tex](x-5)-(x-1)=x-5-x+1[/tex]

[tex]=-4[/tex]

[tex](x-5)+(x+1)=x-5+x+1[/tex]

[tex]=2x-4[/tex]

[tex](x-5)-(x+1)=x-5-x-1[/tex]

[tex]=-6[/tex]

[tex](x-5)+(x-1)=x-5+x-1[/tex]

[tex]=2x-6[/tex]

The answers are

[tex](x-5)-(x-1)=-4[/tex]

[tex](x-5)+(x+1)=2x-4[/tex]

[tex](x-5)+(x+1)=-6[/tex]

[tex](x-5)+(x-1)=2x-6[/tex]

Answer:

$30

Step-by-step explanation:

25% of 40 = 10

40-10 = 30

Answer:

the first one is x= 6-3y or if you are going to solve with the y it will be y =2 - x/3

the second one if you are solving for x it will be x= 2/3 + y if you are solving for y it will be x = 2/3 + x

Step-by-step explanation:

hope this helps

x = 6 - 3y....... equation 1

6x -6y = 4

or, 6 (6 - 3y) - 6y = 4

or, 36 - 18y - 6y = 4

or, 36 - 24y = 4

or, 36 - 4 = 24y

or, 32/24 = y

or, 4/3 = y

Answer:

Step-by-step explanation:

Answer:

1/125

Step-by-step explanation:

Answer:

It is linear because the ratio of the change in the final cost compared to the rate of change in the price tag is constant.

The statement 'it is linear because the ratio of the change in the final cost compared to the rate of change in the price tag is constant' describes this case.

The ratio of the change is the value that one values changes depending on the corresponding change suffered by another variable.

In this case, the ratio of the change is linear because both variables are directly (proportionally) related and determine a constant equation.

In conclusion, the statement 'it is linear because the ratio of the change in the final cost compared to the rate of change in the price tag is constant' describes this case.

Answer:

3 2/3ft²

Step-by-step explanation:

Area of a rectangle = Length × Width

Given

Length = 5 1/2 foot

Width = 2/3foot

Substitute

Area of the rectangle = 5 1/2 × 2/3

Area of the rectangle = 11/2×2/3

Area of the rectangle = 22/6

Area of the rectangle = 11/3

Area of the rectangle = 3 2/3ft²

Answer:

A. -g/-8

Step-by-step explanation:

Since there is a negative sign before the fraction -g/8, A would be the best choice because the negative on the problem given is the same as -g/-8. No matter if there's a negative sign before the fraction, both the denominator and numerator would still be negative.

Answer: A. Repeated results if the player makes 75% of his shots in the long run.

Step-by-step explanation:

The null distribution is always the opposite of the alternative distribution which in most cases represents the claim or hypothesis which is to be tested or performed. In the scenario given, the challenge is to show that a basketball player has an average higher than that of the NBA. NBA average stands at 75%. The alternative hypothesis is the claim, which is ;

H1 : μ > 75%

THE null is thus :

H0 : μ = 75% ; which means that repeated result of the player will yields an average of 75%

Answer:

A

Step-by-step explanation:

The measure of the angle Z is equivalent to 41.7°.

Given is a right angle triangle XYZ.

Using the tangent function, we can write -

tan(Z) = XY/XZ

tan(Z) = 25/28

tan(Z) = 0.89

Z = tan⁻¹(0.89)

Z = 41.7°

Therefore, the measure of the angle Z is equivalent to 41.7°.

Answer:

[tex]\displaystyle \sin(A-B)=\frac{495}{1073}[/tex]

Step-by-step explanation:

We are given that:

[tex]\displaystyle \tan(A)=\frac{35}{12}\text{ and } \sin(B)=\frac{20}{29}[/tex]

Where both A and B are positive acute angles.

And we want to find he value of sin(A-B).

Using the first ratio, we can conclude that the opposite side is 35 and the adjacent side is 12.

Then by the Pythagorean Theorem, the hypotenuse is:

[tex]h = \sqrt{35^2 + 12^2} =37[/tex]

Using the second ratio, we can likewise conclude that the opposite side is 20 and the hypotenuse is 29.

Then by the Pythagorean Theorem, the adjacent is:

[tex]a=\sqrt{29^2-20^2}=21[/tex]

Therefore, we can conclude that:

So, for A, the adjacent is 12, opposite is 35, and the hypotenuse is 37.

For B, the adjacent is 21, opposite is 20, and the hypotenuse is 29.

We can rewrite sin(A-B) as:

[tex]\sin(A-B)=\sin(A)\cos(B)-\cos(A)\sin(B)[/tex]

Using the above conclusions, this yields: (Note that since A and B are positive acute angles, all resulting ratios will be positive.)

[tex]\displaystyle \sin(A-B)=\Big(\frac{35}{37}\Big)\Big(\frac{21}{29}\Big)-\Big(\frac{12}{37}\Big)\Big(\frac{20}{29}\Big)[/tex]

Evaluate:

[tex]\displaystyle \sin(A-B)=\frac{735-240}{1073}=\frac{495}{1073}[/tex]
