Answer:

y = -3/2x + 3

Step-by-step explanation:

To figure out the equation, it is very simple:

First you must find the y-int

The y-int is the point where the line touches the y-axis

The only point that touches the y-axis is (0,3)

so the y-int is 3

Next we need to find the slope, which is rise over run

we must find how far one point is from another point

so we start from the point (0,3) on the y-axis, then we go down 3 and to the right 2 and we are on the point (2,0)

so the slope is -3/2, because the line is going downwards, not upwards

now we just put the equation together, in the slope intercept form

y-int = b = 3

slope = m = -3/2

y = mx + b

y = -3/2x + 3

√(5-2x) - √(2-x) = 1

Eva8 [605]

Square both sides. (5-2x) - (2-x) = 1^2. 5 - 2x - 2 + x = 1. Simplify to get 3 - x = 1. X=2

1. Suppose half of all newborns are girls and half are boys. Hospital A, a large city hospital, records an average of 50 births

kicyunya [14]

Answer:

Step-by-step explanation:

Hospital A (with 50 births a day), because the more births you see, the closer the proportions will be to 0.5.

Hospital B (with 10 births a day), because with fewer births there will be less variability.

The two hospitals are equally likely to record such an event, because the probability of a boy does not depend on the number of births

Solve the system of equations above using it elimination write your answer in the form (x,y) 8X + Y = -16-3X + Y = -5

wlad13 [49]

Given the system of the equation below;

$\begin{gathered} 8x+y=-16----(1) \\ -3x+y=-5----(2) \end{gathered}$

We can use the elimination method to solve the systems of equations

Step 1: Subtract equation 2 from equation 1 and solve for x

$\begin{gathered} 8x+y-(-3x+y)=-16-(-5) \\ 8x+y+3x-y=-16+5 \\ 11x=-11 \\ \frac{11x}{11}=-\frac{11}{11} \\ x=-1 \end{gathered}$

Step 2: Sustitute x = 1 in equation 1

$\begin{gathered} 8(-1)+y=-16 \\ -8+y=-16 \\ y=-16+8 \\ y=-8 \end{gathered}$

Therefore, the solution to the system of equation is

$(-1,-8)$
