Answer:
2
Step-by-step explanation:
Add 7 to both sides.
7x=7+7
2 Simplify 7+7 to 14.
7x=14
3 Divide both sides by 7.
x= 14 divided by 7
x=2
9∉T means that 9 is not an element of the set T .
The two pairs are Pythagorean triples because if you plug the two legs of a right triangle into the Pythagorean theorem(A^2+B^2=C^2), then you will find the measurement for the third side(hypotenuse). i.e. 15^2+12^2=9^2(it's the Pythagorean triple 3,4,5 multiplied by 3). This works with any triple, as long as your using the legs of the triangle and as long as the triangle is a right triangle.
Answer:
y=2/3x+5
Step-by-step explanation:
The change in y is 2
The change in x is 3
So, the rate of change, or slope is 2/3.
Since x=0 means y=5, then our linear function would be y=2/3x+5
