Step-by-step explanation:

-  \frac{4}{5}  + y =  -  \frac{1}{4}  \\ y =  \frac{ - 1}{4}  +  \frac{4}{5}  \\ y =  \frac{ - 5 + 16}{20}  \\ y =  \frac{11}{20}

y =  \frac{11}{20}

Answer:

y = 11/20

Step-by-step explanation:

-4/5 + y = -1/4

Add 4/5 to each side

-4/5  +4/5 + y = -1/4+4/5

y = -1/4 + 4/5

Get a common denominator

y = -1/4 *5/5   + 4/5 *4/4

y = -5/20 + 16/20

y = 11/20

Check

-4/5 +11/20 = -1/4

Get a common denominator

-4/5*4/4 + 11/20 = -1/4*5/5

-16/20 +11/20 = -5/20

-5/20 = - 5/20

Check

How many solutions exist for the system of equations graphed below?
Anestetic [448]

Answer:

One

General Formulas and Concepts:

<u>Algebra I</u>

  • Reading a coordinate plane
  • Solving systems of equations by graphing

Step-by-step explanation:

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

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

We see from the graph that the 2 lines intersect at one point, near x = 1.5.

∴ our systems has 1 solution.

The base of a triangle is 2ft The height of the triangle is 15 in what is the area of the triangle in square inches
Yakvenalex [24]

Answer:

Area of a triangle = A = 180in^{2}

Step-by-step explanation:

Given Data:  

height of a triangle = h = 15 in

base of a triangle = b = 2 feet  = 2*12 =24 in

To Find Out:  

Area of a triangle = A = ?  

Formula:  

Area of a triangle = A =  \frac{1}{2} (b*h)

Solution:  

Area of a triangle = A =  \frac{1}{2} (b*h)

Area of a triangle  = A =  \frac{1}{2} (24*15)

Area of a triangle  = A =  \frac{1}{2} (360)

Area of a triangle = A = 180in^{2}
