How do I graph y = −x+7?

2 answers:

8 0

The slop is -1 and the y-intercept is (0,7) so then go on the graph and plot a point on the y- axis line at 7. Then go right 7 units and down 7 units and that should be it :)

y=-x+7 (let x=7)

y=-7+7

y=0

(7,0)

y=-x+7 (let y=4)

x=3

(3,4)

then the graph will be passing through (7,0),(3,4)

A rectangular plot of farmland will be bounded on one side by a river and on the other three sides by a single-strand electric

larisa86 [58]

Answer:

525 x 1,050

A = 551,250 m²

Step-by-step explanation:

Let 'L' be the length parallel to the river and 'S' be the length of each of the other two sides.

The length of the three sides is given by:

$2S+L=2,100\\ L=2100-2S$

The area of the rectangular plot is given by:

$A=S*L\\A=S(2100-2S)\\A=2100 S -2S^2$

The value of 'S' for which the area's derivate is zero, yields the maximum total area:

$\frac{dA(S)}{dS}=\frac{d(2100 S -2S^2)}{dS}\\0= 2100 - 4S\\S=525$

Solving for 'L':

$L=2100-(2*525)\\L=1,050$

The largest area enclosed is given by dimension of 525 m x 1,050 and is:

$A = 525*1,025\\A=551,250\ m^2$

What solution is this w = 10

alina1380 [7]

Answer:

w = 10

Step-by-step explanation:

9(w - 9) -2 = -7 + 7(w -8)

Expand:

9w - 81 - 2 = -7 + 7w - 56

Rearrange:

9w - 7w = -7 - 56 + 81 + 2

2w = 20

w = 10

Without using technology, describe the end

victus00 [196]

Answer:

Up on the left, up on the right

Step-by-step explanation:

The given function is:

$f(x)=3x^{4}+8x^{2}-22x+43$

The degree of f(x) is 4 i.e. an even degree and the leading coefficient i.e. coefficient with highest powered variable is positive in sign.

The graph of a function with even degree always open on same side from both ends. This depends on the sign of leading coefficient what will be the direction of both ends. The positive sign indicates upward opening and negative sign indicates downward opening.

Since, the leading coefficient of f(x) is positive, it will open towards up from both right and left side. So, the correct option is the fourth option.

PLEASE!! I NEED HELP

elixir [45]

Answer:

Option A, $\frac{1}{7}$

Step-by-step explanation:

<u>Step 1: Determine the numbers that are multiples of 3</u>

8 → Not a multiple of 3

9 → Multiple of 3

14 → Not a multiple of 3

19 → Not a multiple of 3

25 → Not a multiple of 3

34 → Not a multiple of 3

38 → Not a multiple of 3

<u>Step 2: Determine the probability of chosing a multiple of 3</u>

Since we only have 1 number that is a multiple of 3 out of the 7 given numbers, that means that we do the following:

$\frac{(1\ multiple\ of\ 3)}{7\ total\ numbers}$

$\frac{1}{7}$

Answer: Option A, $\frac{1}{7}$

I WILL MARK BRAINIEST!!!

cricket20 [7]

Answer:

-3

Step-by-step explanation:

First you subtract the first equation from the second one and you get:

3x + 3y = 3

x + y = 1

y = 1 - x

Then you use it on the first equation

888x + 889 (1 - x) = 890

888x + 889 - 889x = 890

-x = 1

x = -1

y = 1 - x

y = 1 - (-1) = 2

Now that you have those two numbers, we have to subtract the value of x from y:

x - y

-1 - 2 = -3

Hope this helps bro
