X = 7
Y = 16
Since we know that the bottom two sides are congruent we can make an equation to solve for that X first [2x + 5 = x + 12] . (since we cannot make an equation with the two congruent sides at the top because there are different variables).
Now that we've solved for X which is 7, we can plug it into the top equation [y - 4 = x + 5] which would simplify to [ y - 4 = 12] which would give us 16 for Y<span />
Given two sets X and Y, a relation between X and Y freely associates elements of X with elements of Y, with no restrictions.
A function is a relation with some restrictions: there must be exactly one element of Y connected with each element of X.
The set X is called the domain of the function, and it represents all the possible inputs that we can feed the function with. As we just said, every element of the domain must have a correlated element in Y.
The set Y is called the range of the function, and it represents all the possible outputs that the function can return.
The answer will be yes.
Why?
Well, you know that's it's a linear equation/ function if the exponents are only 1. And by looking at this equation you'll see that there are no exponents other than 1. So the answer is yes, it is a linear equation.
Okay. There are 0.13kg of salt for every liter of water. To find the amount of salt in 70 liters of water, all we have to do is multiply 0.13 by 70. 0.13 * 70 is 9.1. There are 9.1 kilograms of salt in 70 liters of water.
Answer: correct trigonometric ratios
SinB, tanA and cos A.
Step-by-step explanation:
The right triangle has two sides 5 and 12 , by Pythagoras it's hypotenuse is 13.
Tan B=5/12,
Sin A =12/13
