6x-7 = 2x+3

 add 7 to each side

= 6x = 2x+10

 subtract 2x from each side

4x=10

divide both sides by 4

 x = 10/4 = 5/2

6(5/2)-7 = 8

8*2 = 16

 JK is 16

If M is the midpoint of JK then JM+MK=JK and JM=MK
so
6x-7=2x+3
minus 2x both sides
4x-7=3
add 7 both sides
4x=10
divide both sides by 4
x=\frac{10}{4}
x=\frac{5}{2}

sub back

JM=6x-7
JM=6(\frac{5}{2})-7
JM=\frac{30}{2}-7
JM=15-7
JM=8

JM=MK=8
JM+MK=8+8=16=JK

x=\frac{5}{2} and JM=8=MK and JK=16

Write the equation for the graphed function. I worked out y = 5 - 4 (x + 4)^2 but that isn't right. Any help would be appreciate
alexira [117]

Vertex form for a parabola with vertex (p,q) is

y = a(x-p)^2 + q

We have (p,q)=(-4,5) and another point (-3,2) so we can solve for <em>a:</em>

2 = a(-3 - -4)^2 + 5

2 = a + 5

a = -3

Putting it together,

Answer: y = -3(x + 4)^2 + 5

We could multiply that out if we like but I won't bother.

The width of a rectangular rug is 6 feet if the perimeter is 24 feet what is the area of the rug?
babymother [125]

Answer:

36 feet squared

Step-by-step explanation:

Finding the perimeter of an object is adding all of the sides together. If the width of the rug is 6 feet then we know that there are two sides that length. Add those together.

6 feet + 6 feet = 12 feet

You would subtract the number you get from the perimeter.

24 feet - 12 feet = 12 feet

And then divide the number by the number of sides left, 2, to get each of their lengths.

12 feet / 2 feet = 6 feet

To find the area of a rectangle you multiply length times width, which in this case both are 6 feets.

6 feet x 6 feet = 36 feet squared
