The value of the function f(x) = ( 8x² - 2x + 4 ) / 2 when x = -3/5 is 101/25.

Hence, f(-3/5) = 101/25.

<h3>What is the value of the function at f(-3/5) ?</h3>

Given the function; f(x) = ( 8x² - 2x + 4 ) / 2

To determine the value of the function when x = -3/5, we simply replace the variable x with -3/5 in the function.

f(x) = ( 8x² - 2x + 4 ) / 2

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

Divide each term by 2

f(-3/5) = 4(-3/5)² - (-3/5) + 2

f(-3/5) = 4(9/25) - (-3/5) + 2

f(-3/5) = 36/25 +3/5 + 2

f(-3/5) = ( 36 + 3×5 + 2×25 ) / 25

f(-3/5) = ( 36 + 15 + 50 ) / 25

f(-3/5) = 101/25

The value of the function f(x) = ( 8x² - 2x + 4 ) / 2 when x = -3/5 is 101/25.

Hence, f(-3/5) = 101/25.

-x+4y=24 and -2x+y=-8 as an ordered pair
Stels [109]

Answer: (8,8)

Step-by-step explanation:

First you need to get a x or y by itself.

I choosed to get y by itself since it would be faster.

-2x + y = -8  (first get -2x to the other side so add 2x)

y = -8 + 2x (then you want to insert that to the other equation)

-x + 4( -8 +2x) = 24      ->    -x -32 + 8x = 24   ->   7x -32 = 24

(add 32 to the other side)

7x = 56 (divide 7 to 56 to get x) x = 8

now insert into the other equation

-2( 8 ) + y = -8     ->     -16 + y = -8 ( move -16 to the other side, so add 16)

then you get your answer, y= 8

Solve for x: 2/7 (x - 2) = 4x <br> (9th grade algebra 1)
Nimfa-mama [501]

Answer:

<h2>x =  -  \frac{2}{13}</h2>

Step-by-step explanation:

\frac{2}{7} (x - 2) = 4x

=  >  \frac{2}{7} x -  \frac{4}{7}  = 4x

=  >  \frac{2}{7} x - 4x =  \frac{4}{7}

=  >  \frac{2x - 28x}{7}  =  \frac{4}{7}

=  >  \frac{ - 26}{7} x =  \frac{4}{7}

=  > x =  \frac{4}{7}  \times  \frac{7}{ - 26}

=  > x =  \frac{4}{ - 26}

=  > x =  \frac{ - 2}{13} (ans)

A rectangular garden measuring 13 meters by 15 meters is to have a gravel pathway of constant width built all around it. There i
Shtirlitz [24]

Let w represent width of the pathway.

We have been given that a rectangular garden measuring 13 meters by 15 meters is to have a gravel pathway of constant width built all around it.

Since pathway will be on all sides, so new length and width of garden with pathway would be 13+2w by 15+2w.

We are also told that there is enough gravel to cover 80 square meters. This means that area f pathway should be equal to 80 square meters.

The area of the pathway will be equal to area of garden with new dimensions minus area of garden with original dimensions.

We know that area of rectangle is width times length.

\text{Area of pathway}=(15+2w)(13+2w)-15(13)

Since we are asked to write an inequality that represents all possible widths(w), in meters, of the pathway, so area of pathway should be less than or equal to 80 square meters.

(15+2w)(13+2w)-15(13)\leq 80

Therefore, our required inequality would be (15+2w)(13+2w)-15(13)\leq 80.
