<u>Algebra I</u>

Reading a Cartesian Plane

  • Coordinates (x, y)
  • Graphing

Solving systems of equations by graphing

Step-by-step explanation:

Where the 2 lines intersect is the solution set to the systems of equations.

If the 2 lines are parallel, they will have no solution.

If the 2 lines are the same line, they will have infinite solutions.

Find angle abc (2x+14) (x+7)
melisa1 [442]
It's a complementary angle, so just solve for x and subtract the CBD from 90, 
First, we have to solve for x.
2x + 14 + x + 7 = 90
Combine like terms
3x + 21 = 90
Balance, subtract 21 from each side.
3x = 69
Divide 3 from each side
x = 23.
So know that we know x is 23, we can go about it 2 ways, subtracting the other angle with 90 or just substituting the variable, I'd just substitute the variable for it so just do 23 + 7. That equals 30, angle ABC = 30.

Answer:

JK=  3 in

Step-by-step explanation:

There is a theorem that says that the angle of a tangent and the radius is of 90°

so we can use the pythagora's theorem

JK^2+JH^2=HK^2\\JK^2+(4)^2=(5)^2\\JK^2+16=25\\JK^2=9\\JK=3

Mahad and Eren made 17 ounces of pizza dough. They used 5/8 of the dough to make a pizza and used the rest to make calzones.

Answer:

  B)  4 2/8 ounces

Step-by-step explanation:

After 5/8 of the dough was used for pizza, the remaining amount is ...

  1 -5/8 = 3/8

The difference between the amounts is then ...

  (5/8×17 oz) - (3/8×17 oz) = (5/8 -3/8)×17 oz = 2/8×17 oz = 34/8 oz

  = 4 2/8 oz
