Answer:
Rational number
Step-by-step explanation:
Any number that can be written as a ratio of two integers is a rational number.
In the question, you have the keyword 'ratio', meaning a comparison between two numbers. For example 1.5 can be expressed as the ratio between 3 and 2 (3/2), as a fraction.
<u>When a number cannot be expressed as a fraction, it's called an irrational </u>number. <u> The most famous irrational number of all would be pi (π). </u> You cannot express pi in a ratio between numbers, because it's too complicated, it's basically an infinite number without any periodicity.
Answer:
(-2,-6)
-2
Step-by-step explanation:
To get the vertex take the number that's in the parathenses with the x and flip it's sign (in this case to a negative) which means we have
-2
this is the x coordinate of the vertex.
Next take the number that's being subtracted (or added) on the outside and leave that as is (-6)
This is the y coordinate
which means we have (-2,-6)
the axis of symmetry is just the x coordinate of the graph
which is -2
Slope m= (y2-y1)/(x2-x1)=(8-0)/(2-(-2))=8/4=2
y=mx+b
y=2x+b
Take the point (-2,0)
0=2*(-2)+b
b=4
y=2x+4=2(x+2)
Answer is A. y=2(x+2)

Here you go mate
Step 1
2x+15=82-9 Equation/Question
Step 2
2x+15=82-9 Simplify
2x+15=73
Step 3
2x+15=73 Subtract
2x=58
Step 4
2x=58 Divide by 2
answer
x=29
I think it would be the left on the 1
