Solve for x -1/2x + 3 = -x + 7

Mathematics
1 answer:
Alex73 [517]3 years ago
7 0

Answer:

8

Step-by-step explanation:

If you add x to the left side of the equation you get positive 1/2x +3=7

you then would subtract 3 from 7 to get 4

this would leave you with 1/2x=4

if you divide 4 by 1/2 you get 8 as the answer.

What is the y-coordinate of the midpoint of WU?<br> A 2.5<br> B. -1.5<br> C. -0.5<br> D. 1.5
lilavasa [31]

Option C: -0.5 is the right answer

Step-by-step explanation:

Given is the graph on which different points are indicated.

We have to find the y-coordinae of the mid-point of WU.

The formula for mid-point is:

(\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2})

So we only have to know the y-coordinates of both points to find the mid-points y coordinate

So by observing the graph we get

y_1 =0

y_2 = -1

So,

\frac{0-1}{2}\\= \frac{-1}{2}\\= -0.5

Hence,

Option C: -0.5 is the right answer

Suppose that y varies inversely with x. Write a function that models the inverse function. x = 5 when y = 7
Dovator [93]
Varying inversely means y=a number divided by x
find the number: 7=k/5 =>k=35
so the equation is y=35/x

Y=-x-3
nadya68 [22]

Answer: Heyaa! :)

  • <em>1. y=-x-3 = -1</em>

<em>Slope:  </em>−1

<em>y-intercept: </em>(0,−3)

  • <em>2. y=4x-5 =</em> 4

<em>Slope:</em> 4

<em>y-intercept: </em>(0,−5)

  • <em>3. 2x-y=-2 =</em> 2

<em>Slope:</em> 2

<em>y-intercept:</em> (0,2)

  • <em>4. x+y=4 =</em> 1

Slope: −1

<em>y-intercept:</em> (0,4)

  • <em>5. 3x+4y=-12 = - 3/4</em>

<em>Slope: </em>−3/4

<em>y-intercept: </em>

(0,−3)

Hopefully this helps<em> you!</em>

3c - b = 2a solve for c
alekssr [168]

Answer:

c = \frac{2a + b}{3}

Step-by-step explanation:

3c - b = 2a \\ 3c = 2a + b \\   \frac{3c}{3}  =  \frac{2a + b}{3}  \\ c = \frac{2a + b}{3}

<em>hope</em><em> </em><em>this</em><em> </em><em>helps</em><em> </em><em>you</em>

<em>let</em><em> </em><em>me</em><em> </em><em>know</em><em> </em><em>if</em><em> </em><em>you</em><em> </em><em>have</em><em> </em><em>another</em><em> </em><em>questions</em><em>:-)</em>

A cyclist rides his bike at a rate of
docker41 [41]
15 miles per hour right so anyways that will be split by the number of minutes per hour so first there are 60 mins in an hour so its 15 divided by 60 which is 0.25 next how many miles will the cyclist travel in 15 minutes so that would mean taking the answer from the above and multiply it by 15 since you need 15 min which is 3.75 miles in 15 min hope i helped rate brainiest so i can reach next lvl! :)
