(-2,2), (4,-4). There are two common ways to attack this problem. The distance formula and Pythagorean theorem. I would use Pythagorean. make line segment cd the hypotenuse of a right triangle. legs would be 6 units and 6 units. a^2+b^2=c^2. 6^2+6^2=c^2.  c^2=36+36. c^2=72. c=sq root of 72. c=8.5

PLEASE HELP FAST!!! How many solutions does this system have?
Aneli [31]

Step-by-step explanation:

  • y=3/4x+(-5)
  • -4x+4(3/4x+-5)=-20

-4x+3x-20=-20

-x=-20+20

-x=0

x=0

  • x=0 in y=3/4x-5

y=3/4×{0}-5

y=-5

Please help me and others that will stumble on this problem.
lutik1710 [3]

Answer:

A (0,0)

Step-by-step explanation:

When a function intersects the y-axis then the point of intersection is called y-intercept of the function,

Also, for y-intercept x = 0.

That is, if f(x) is the function then its y-intercept is (0, f(0) )

By the given table for x = 0, f(x) = 0

Hence, the y-intercept of the given function is (0,0),

Option A is correct.

The measure of an angle is 152°. What is the measure of its supplementary angle?
34kurt

Answer:

\huge{\boxed{\boxed{\tt { ⎆ Answer :- }}}} \

Supplementary angles form 180°.

One angle = 152°

Other angle = y°

152 + y = 180 \\ y = 180 - 152 \\ y = 28

➳ The measure of its supplementary angle is <u>28</u>°.
