Which ordered pair would form a proportional relationship with the point graphed below?
jolli1 [7]

Answer:

(5, 20)  

Step-by-step explanation:

We can find the slope of the line

m = (y2-y1)/(x2-x1)

    = (40-0)/(10-0)

    = 40/10

    =4

Since the line goes through (0,0) the y intercept is 0

y = mx+b

y = 4x

Lets check the points  by substituting into the equation

40, 10)     10 = 4*40   10 =160  no

(–5, –10)    -10 = 4*-5    10 = -20   no

(5, 20)       20 = 4*5    20 = 20  yes

(–10, –20)    -20 = 4*-10    -20 = -40   no

If three times a number added to 8 is divided by the number plus 7, the result is four thirds. Find the number.​
Marina86 [1]

9514 1404 393

Answer:

  4/5

Step-by-step explanation:

The wording is ambiguous, as it often is when math expressions are described in English. We assume you intend ...

  \dfrac{3n+8}{n+7}=\dfrac{4}{3}\\\\3(3n+8)=4(n+7)\qquad\text{multiply by $3(n+7)$}\\\\9n+24=4n+28\qquad\text{eliminate parentheses}\\\\5n=4\qquad\text{subtract $4n+24$}\\\\\boxed{n=\dfrac{4}{5}}\qquad\text{divide by 5}

The number is 4/5.

The midpoint M of the line segment AB is (-3,7). If the coordinate of B is (5,-1), what is the coordinate of the point A?
sleet_krkn [62]

Answer:

Coordinate of Point A is (-11, 15)

Step-by-step explanation:

M -- (-3, 7)

B -- (5, -1)

Therefore, (5 + x)/2  = -3

x = -11

(-1 + y)/2 = 7

y = 15

Therefore Point A is (-11, 15)
