Graph each line using intercepts 1/4 x + 2y =2
Leno4ka [110]

The given equation is,

\frac{1}{4}x+2y=2

It can be rewritten in the form of y=mx+c, where c is the y intercept.

Hence,

\begin{gathered} 2y=-\frac{1}{4}x+2 \\ y=\frac{-1}{4\times2}x+\frac{2}{2} \\ y=\frac{-1}{8}x+1 \end{gathered}

Put different values for x and find value of y.

When x=0, y=1.

When x=1,

y=\frac{-1}{8}+1=\frac{7}{8}

The graph is,

write the standard form of the equation of the circle with endpoints of a diameter at the points (9,2) and (-7,5)
AnnyKZ [126]

Answer:

Step-by-step explanation:

Answer:

(x-1)²+(y-3.5)² = 265/4

Step-by-step explanation:

first find the midpoint (center of the circle)

(9+-7)/2, (2+5)/2

(1, 3.5) = center

then distance formula to find diameter

√(9- -7)²+(2-5)²=√256+9 = √265

The radius is half the diameter = (√265)/2

Formula for circle is (x-h)²+(y-k)²=r², where (h, k) is the center

Now you can plug everything in.

(x-1)²+(y-3.5)² = 265/4

Can someone answer it please I really need help please I need it right now I was so frustrating please help and please show work
Eduardwww [97]

Answer:

  2 1/4 yards above sea level

Step-by-step explanation:

The midpoint elevation is the average of the endpoint elevations, their sum divided by 2. When elevation is below sea level, it is represented by a negative number.

  (17 3/4 - 13 1/4)/2 = (4 2/4)/2 = 2 1/4 . . . yards above sea level
