A triangle ABC with vertices A(6,8) B(6,12) C(10,12) is rotated to 180. What are the coordinates of B

Assuming rotation is about origin, then
R180:  (x,y)->(-x,-y)

So
A(6,8)->A'(-6,-8)
B(6,12)->B'(-6,-12)
C(10,12)->C'(-10,-12)

∠G and ∠H are supplementary; m∠G = (x + 4)° and m∠H = (4x + 11)°. What is the measure of ∠G? What is the measure of ∠H?
iogann1982 [59]

Answer:

∠G =  37°

∠H = 143°

Step-by-step explanation:

As we know ,

Sum of supplementary angles is 180 degrees.

Hence sum of ∠G and ∠H  is also 180 degrees

∠G + ∠H = 180

Substituting the given values in above equation, we get -

(X+4) + (4X +11) = 180\\5X + 15 = 180\\5X = 165\\X = 33

∠G = (x + 4)° = (33 + 4)° = 37°

∠H = (4x + 11)° = (33*4 + 11)° = 143°

A gasoline pump delivers 4 2/5 gallons of gas per minute. How many minutes will it take to fill a gas tank that holds 17 1/4 gal
Liono4ka [1.6K]
Well if it pumps 4 2/5 per minute that is equal to 4 4/10 in a minute or 4.4 because you multiply the top and bottom of the fraction by two. it’s still the same fraction but it is easy to convert to a decimal now. you could use this fraction but it’s much easier to use decimals. Because the first number is a decimal you should make the second one a decimal too. To do this you need to know that 1/4 of 100 is 25. so now we have these numbers and all you do now is divide 17.25 by 4.4 which could be rounded to 4 because it’s a long decimal

Which statement is true regarding the functions on the
prisoha [69]

Answer:

f(2) = g(2)

General Formulas and Concepts:

<u>Alg I</u>

  • Reading a Cartesian Plane
  • Identifying Coordinates
  • Solutions of systems of equations

Step-by-step explanation:

We see from the graph that f(x) and g(x) intersect at x = 2. Therefore, the point at x = 2 would be equivalent in both graphs/be a solution to both equations.

Therefore, f(2) must equal g(2), as they intersect each other at that point and have the same value of 0.
