Answer 2

The value of the function f(x) = 3x - 5, at f(20) = 55 and at f(140) = 415.

What is a function?

A function can be defined as the outputs for a given set of inputs.

The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.

Given, A function f(x) = 3x - 5.

Now, The value of f(20) is the same as replacing x with 20.

Therefore, f(20) = 3(20) - 5.

f(20) = 60 - 5.

f(20) = 55.

Similarly, f(140) = 3(140) - 5.

f(140) = 420 - 5.

f(140) = 415.

A large field measures 70 feet by 525 feet. If you divide it up into equal square garden plots, what size would the largest possible plot be with sides of whole number length?​

Answers

9514 1404 393

Answer:

  35 feet square

Step-by-step explanation:

The greatest common factor of 70 and 525 is 35. The largest square plot can be 35 feet on a side.

  70 = 2·35

  525 = 15·35

I like to find the GCD (greatest common divisor) using Euclid's algorithm. We find the remainder when dividing the larger by the smaller. When that remainder is not zero, we replace the larger number with the remainder, and repeat. When the remainder is zero, the divisor is the GCD.

  525/70 = 7 r 35

  70/35 = 2 r 0 . . . . . 35 is the GCD

Answers

c i’m pretty sure but i also have a 39% in math rn but that sounds right

Answer:

C) Do the inverse or opposite operations

Step-by-step explanation:

Take for example the equation 4=2x. Because 2 is being multiplied by x, the only way for x to get by itself is to do the opposite operation; dividing both sides by 2 to get 2=x.

Mrs. Hector wanted to bring giant souvenir snow globes, which weigh 1.5 kg each, back to the USA as presents for her students. Mrs. Hector's suitcase weighs 2.4 kg, but she wanted to fill it with as many snow globes as possible. Write and solve an inequality to determine the maximum number of snow globes that Mrs. Hector could have brought back in her suitcase.

Answers

Answer:

the maximum number of snow balls can bought back = 1.6

Step-by-step explanation:

Let

Mrs. Hector brings total number of giant snow globes = x

As given,

weight of 1 snow globe = 1.5 kg

So,

Weight of x snow globe = 1.5x

As given,

She have to take them in a suitcase of weight 2.4 kg

For number of snow globes we have the equation,

1.5x = 2.4

⇒x = [tex]\frac{2.4}{1.5}[/tex] = 1.6

So, the maximum number of snow balls can bought back = 1.6

What is the answer hurry!!!

Answers

Answer:

D. 9 + 4√5

Step-by-step explanation:

What we're essentially doing here is squaring 2 + √5. (2 + √5 and 2 + 1√5 are essentially the same)

(2 + √5)(2 + √5) (I didn't put the one on the conjugate for a reason; look above)

Step 1: Apply the distributive property by multiplying each term of 2 + √5 by 2 + √5

4 + 2√5 + 2√5 + (√5)²

Step 2: Combine 2√5 and 2√5 to get 4√5.

4 + 4√5 + (√5)²

Step 3: The square of √5 is 5.

4 + 4√5 + 5

Step 4: Add 4 and 5 to get 9.

9 + 4√5 is the final answer to this question.

Each time Sally waters her tomato plants she uses 5 liters of water. If Sally waters her tomato plants 3 times a week, then how much water, in liters, does Sally use in a week? liters

Answers

Given:

Each time Sally waters her tomato plants she uses 5 liters of water.

Sally waters her tomato plants 3 times a week.

To find:

How much water, in liters, does Sally use in a week?

Solution:

We have,

Water used in each time = 5 liters

Number of times Sally waters her tomato plants = 3 times

Now,

Water used in 1 time = 5 liters

Water used in 3 time = 3×5 liters

                                   = 15 liters

Therefore, the Sally use 15 liters of water in a week.

Which is an example of having infinitely many solutions? 1 Point 2x+8 = 2(x+8) 3x + 2(x - 2) + 6 = 5x + 2 x+7=7 X=0

Answers

Given:

The different equations in the options.

To find:

The equation which have infinitely many solutions.

Solution:

In option A,

[tex]2x+8=2(x+8)[/tex]

[tex]2x+8=2x+16[/tex]

[tex]8=16[/tex]

This statement is false for any real value of x. So, the given equation has no solution.

In option B,

[tex]3x+2(x-2)+6=5x+2[/tex]

[tex]3x+2x-4+6=5x+2[/tex]

[tex]5x+2=5x+2[/tex]

[tex]2=2[/tex]

This statement is true for all real value of x. So, the given equation has infinitely many solutions.

In option C,

[tex]x+7=7[/tex]

[tex]x=7-7[/tex]

[tex]x=0[/tex]

This equation has only one solution, i.e., x=0.

In option D,

[tex]x=0[/tex]

This equation has only one solution, i.e., x=0.

Only equation [tex]3x+2(x-2)+6=5x+2[/tex] has infinitely many solutions. Therefore, the correct option is B.

Which equation represents the line that has a slope of -2 and passes through the point (6,5)?
A. y= -2.6 - 17
B. Y = -23 - 16
c. y = -2x + 16
D. y = -2.c + 17
Pls don’t write random thing I really need helllppp

Answers

Answer:

y = - 2x + 17

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 2, then

y = - 2x + c ← is the partial equation

To find c substitute (6, 5) into the partial equation

5 = - 12 + c ⇒ c = 5 + 12 = 17

y = - 2x + 17 ← equation of line
