Figure ABCD is graphed on a coordinate plane.

Phoenix [80]

1. BC is 1+3=4 (units)

2. AD is 3+5= 8 (units)

3. Draw the altitude CH from point C, as shown in the figure.

4. Then triangle CHD is a right triangle, with hypothenuse CD, and sides HD and CH.

5. $CD^2=HD^2+CH^2$

$CD^2=2^2+4^2=4+16=20$

$CD= \sqrt{20}= \sqrt{4*5}= \sqrt{4} * \sqrt{5}=2 \sqrt{5}= 4.47$

6. AB=CD=4.47 because the trapezoid is isosceles.

7. P= BC+AD+AB+CD=4+8+4.47+4.47=20.9 (units)

if you subtract the least integer from the greatest integer and divide the difference by 3 the quotient is 5

vodomira [7]

Let a and b be integers and b>a, then we can say:

(b-a)/3=5 now multiply both sides by 3

b-a=15

b=15+a

So there are infinitely many pairs of integers that satisfy the conditions given in the problem. For any value a, b will be 15 units greater.

Can anyone help me please!!

serious [3.7K]

Since x=-1 and y=3
ax-2y=4
a(-1)-2(3)=4
-a-6=4
-a=10
a=-10

5x+by=-1
5(-1)+b(3)=-1
-5+3b=-1
3b=4
b=4/3

What is Domain and Range of the graph

Katena32 [7]

Answer:

Use the vertical line testing, which means that if the line touches one point then it is a function. If it touches more than 1 point, then it is not a function. Also, if one x value leads to one y-value then it is a function. If different x-values lead to one y-value it is also a function.
