What is the value of y that satisfies the equation below 5-y/2=9

Andrew [12]

5-y/2 = 9

First, we do the inverse operation and subtract 5 from both sides.

5 - y/2 = 9
-5 -5

-y/2 = 4

Now, we do the inverse operation ( multiply by the reciprocal)

-y/2 = 4
-y/2 * -2 = 4* -2
y= -8
y=-8

Now we have our final answer: y=-8

Check our work

5 - - 8/2= 9
5+4=9
9=9

OUR ANSWER IS CORRECT! :)

A rectangular parcel of land is 90 ft wide. the length of a diagonal between opposite corners is 30 ft more than the length of t

snow_lady [41]

solution:

One leg of the triangle is given 90ft. the other leg of the triangle is x, and the hypotenuse is given as x+30

According to Pythagoras,

C² = a² + b²

So,

(x +30) = x² + 90²

Use FOIL to expand the binomial:

x² + 60x + 900 = x² + 8100

60x = 7200

X = 7200/60

X = 120

Does the point (2, -2) lie on the line 3x − y = 4?

blagie [28]

Answer:

Step-by-step explanation:

When you plug in (2,-2) into the equation, the solution does not equal 4. So the point (2,-2) does not lie on the line.
