For any linear function f(x) = mx + b, when does 5f(x) = f(5x) + 5? A. when b = 0 B. when b = 54 C. when b = 5 D. always

Answers

Answer 1

Answer:

b = 5/4

Step-by-step explanation:

Equations

Given the function:

[tex]f(x)=mx+b[/tex]

It's required to find the value of b such that:

[tex]5f(x)=f(5x)+5[/tex]

Substituting:

[tex]5(mx+b)=5mx+b+5[/tex]

Operating:

[tex]5mx+5b=5mx+b+5[/tex]

Simplifying:

[tex]5b=b+5[/tex]

Subtracting b:

[tex]4b = 5[/tex]

Dividing by 4:

b = 5/4

Step-by-step explanation:

If you follow the dotted lines and bring all the lines together,

angle8 = angle4 (corresponding angles)

angle8 = angle5 (vertically opposite angles)

angle5 = angle1 (corresponding angles)

Therefore, angle8 is basically the same as angles 1 and 4

The cost of 4 pounds of bananas is $3.52. What is the constant of proportionality that relates the cost of dollars, y, to the number of pounds of bananas, x?

Answers

Answer:

B. $0.88

Step-by-step explanation:

x = number of bananas

y = cost of bananas in dollars

Given that 4 bananas cost $3.52, the constant of proportionality that relates cost of bananas, y, to the number of pounds of bananas, x = y/x

y = 3.52

x = 4

Therefore:

Constant of proportionality = [tex] \frac{3.52}{4} = 0.88 [/tex].

Two sides of a rectangle differ by 3.5cm.Find the dimensions of the rectangle if its perimeter is 67cm.
the answer should contain step by step and understandable explanation.

Answers

Answer:

Sides are x and x + 3.5 cm

Perimeter = 2(x + (x + 3.5))cm

4x +7 = 67

x = 15cm Answer

Step-by-step explanation:

HOPE THIS HELPED!

One side = x
The other side = x+3.5
Perimeter is 2(L*w)
Perimeter is 2(x + x + 3.5)
2(2x + 3.5) = 67
4x + 7 = 67
4x = 60, x = 15
15 + 3.5 = 18.5
One side is 15cm, the other side is 18.5 cm

[tex]\huge\boxed{m\angle 1 = 131 \textdegree}[/tex]

[tex]\huge\boxed{m\angle 2 = 49 \textdegree}[/tex]

[tex]\huge\boxed{m\angle 3 = 112 \textdegree}[/tex]

Step-by-step explanation:

We can use basic angle relationships to find the measure of angles 1, 2, and 3 here.

First off, we know that the 49° angle and m∠1 are supplementary. This means that their angle measures will add up to 180°.

Since we know one, we can find the other easily.

[tex]x + 49 = 180\\\\x = 180-49\\\\x = 131[/tex]

So m∠1 = 131°.

We also know that m∠2 is opposite to the 49° angle. This means that m∠2 is also 49°.

Now, we know that m∠3 is also opposite to the 112° angle. Therefore, their angle measures are the same, and m∠3 is also 112°.

O 45% are women
55% are men
55% are women
O 75% are men
O 75% are women

Answers

Answer:

55% are women

Step-by-step explanation:

27÷60= 0.45

0.45x100=45

100-45=55

45% men

55% women

There are 55% are women if the manufacturing plant has 60 supervisors. If 27 of the supervisors are men, option third is correct.

What is the percentage?

It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.

We have:

A manufacturing plant has 60 supervisors. If 27 of the supervisors are men.

The number of women = 60 – 27 = 33

The percent of women = (33/60)×100

= 0.55×100

= 55%

Thus, there are 55% are women if the manufacturing plant has 60 supervisors. If 27 of the supervisors are men, option third is correct.

Every week, a car dealer ship sells at least 5 minivans. Write an inequality that represents this situation. Let c represent the number of minivans sold each week.

Answers

Answer:

An inequality 'c ≥ 5' represents this situation.

Step-by-step explanation:

We know that the inequality symbol '≥' represents 'at least'.

For example, 'x≥y' means 'x' is greater than or equal to b. It means 'x' is at least equal to 'y'.

Let 'c' represent the number of minivans sold each week.

As a car dealer ship sells at least 5 minivans. It means the dealer can also sell more than 5.

i.e. c ≥ 5

Therefore, an inequality 'c ≥ 5' represents this situation.

If we multiply 0.8 by 1/50, we get 0.8 × 1/50 = 0.8/50 = 0.016 meter. So, we can say 0.016 meter wide should the door be on the scale drawing, if the ratio is 1 to 50.

Answers

Answer:

the ratio is 1:50

this means that 1 meter in the drawing is equal to 50 meters in real life, but that is a complicated way of stating something simple since drawings are not generally measured in meters.

the door is 0.8 meters wide or 80 centimeters wide

in our drawing, the door should be 80 / 50 = 1.6 centimeters wide

the whole purpose of a scale is to allow us to work with smaller units, that is why we have to work with them. It is true that 0.016 meters = 1.6 centimeters, but as I said before, writing the answer in meters just complicates things and makes them harder to understand. You could also say it is 0.000016 kilometers wide and it would be right, but too confusing.
