Okay, so since the discount is 60% of the price and it comes out to $2.8, we are going to form the following expression, where x is the original price.
60% of x = 2.8
Simply means: 60/100 * x = 2.8
You solve for x, which comes out to $4, which is your original price.
Answer:
d.
D: {-7, 0, 2, 6}
R: {-13, 0, 5, 13}
Step-by-step explanation:
Domain of a relation is the set of all input values (x-values) while the range is the set of all corresponding output values (y-values) in a given relation.
Given the relation represented by the table above,
Domain would be: {-7, 0, 2, 6}
Range: {-13, 0, 5, 13}
Sum of angles of a triangle = 180
a+b+c=180
a + (5a) + (4a-13) = 180
Simplify and solve for a:
10a-13=180
10a=193
a=19.3
b=5*19.3=96.5
c=4*19.3-13=77.2-13=64.2
Check: a+b+c=19.3+96.5+64.2=180 ok.
