If f(x)= –2x+3 then f(3) – f(4)=

Answers

Answer 1

Answer:

2

Step-by-step explanation:

F(3) means that we plug in 3 for the x value of the original equation, and F(4) means that we plug in 4 for the x value of the original equation

F(3) = -2(3) + 3

= -3

F(4) = -2(4) + 3

= -5

- 3 -(-5) = 2

Answer 2

Answer:

2

Step-by-step explanation:

Step 1: Solve for f(3)

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

Step 2: Solve for f(4)

[tex]f(4) = -2(4) + 3[/tex] [tex]f(4) = -8 + 3[/tex] [tex]f(4) = -5[/tex]

Step 3: Subtract f(4) from f(3).

[tex]f(3)-f(4)[/tex] [tex](-3)-(-5)[/tex] [tex]-3 + 5[/tex] [tex]2[/tex]

Therefore, the answer is 2.

WILL MARK BRAINLIEST ANSWER​

Answers

Answer:

v = 1

u = 2

Step-by-step explanation:

Given is a special right triangle with angle measures as follows:

90-60-30

The side lengths would be :

2x- x[tex]\sqrt{3}[/tex]-x

in the image it shows that the second side length (the one that sees angle measure 60) is [tex]\sqrt{3}[/tex] from this we can conclude x = 1 so:

v = 1 and

u = 2

Peter brought 8 lemons for 6 dollars each lemon was the same price what was the cost for 1 lemon.

Answers

Answer:

75 cents

Step-by-step explanation:

We can use a ratio to solve

8 lemons      1 lemon

------------- = ------------

6 dollars        x dollars

Using cross products

8x = 6*1

8x = 6

Divide by 8

8x/8 = 6/8

x = .75

One lemon costs .75

3x-5y-7=0
X=2k-1.
Y=k

Answers

Answer:

x = 19

y = 10

Step-by-step explanation:

3x - 5y - 7 = 0

x = 2k - 1

y = k

3x - 5y = 7

x = 2y - 1

3 * (2y - 1) - 5y = 7

6y - 3 - 5y = 7

6y - 5y = 10

y = 10

x = 2 * 10 - 1

x = 19

The 10 largest soccer and football stadiums have a capacity of at least of 1 x 105 people. Each stadium has 8 events each year for 10 years.

How many total people attended these events if every event was seated to capacity? Select ALL that apply

at least 80,000,000 people

B

С

at least 0.8 x 107 people

D

at least 8 x 107

people

E

at least 80 x 107 people

Answers

We have 10 stadiums each holding 105 people.
If each stadium has 8 events each year that’s 80 events per year in total.
So there is 800 events throughout the 10 years (each year holding 80 events).
To find the total number of people that attended the event we multiply the number of people that attended each event by how many events we had in total (105x800=84000)
So, C,D and E apply.

What is the simplest fraction whose value is equal to the number $\textcolor{red}{\heartsuit}$ depicted on this number line?


(Give your answer as a fraction, not a mixed number. "Simplest fraction" means the numerator and denominator should have no common divisor greater than 1. For example, 5/6 is a fraction in simplest form, but 4/6 is not in simplest form because a common divisor of 2 can be factored out of the numerator and denominator. The simplest form of 4/6 is 2/3.)

KL = 6 units

Recall:

Congruent triangles have the same shape and size.Congruent triangles have all corresponding angles and side lengths congruent to each other.

Given that:

4x+4=5

Next, you subtract 4 from each side.
