If we take the numbers to be hmm say "a" and "b"
let's say "a" is the bigger number, how big?

well "<span>One number is 10 more than another"
so... whatever "b" is, "a" is THAT plus 10, or
a = b+ 10

now, how much is twice the smaller? the smaller is b
twice b, is 2 * b or 2b

what about three times the larger? the larger is a
thrice a is 3 * a or 3a

we're told that 2b + 3a = 55
thus</span>\bf \begin{cases}&#10;a=b+10&#10;\\\\&#10;2b+3a=55\\&#10;--------------\\&#10;2b+3\left( \boxed{b+10} \right)=55&#10;\end{cases}

solve for "b", to see what the smaller one is

what about "a"? well, a = b + 10

Given:

The graph of a parabola.

To find:

The domain, range and check whether it is a function or not.

Solution:

Domain: The set of x-values or input values is known as domain.

Range: The set of y-values or output values is known as range.

A relation is a function if their exist unique outputs for each input. In other words a graph is a relation if it pass the vertical line test.

Vertical line test: Each vertical line intersect the graph at most once.

The given function is defined for all real values of x which are greater than or equal to -3. So, the domain of the given graph is:

Domain=[-3,\infty)

The given function values can be any real number. So, the range of the given graph is:

Range=(-\infty,\infty)

For x=0, we have two values of the function because the graph intercept the y-axis at two points.

Since the graph does not pass the vertical line test therefore the given graph is not a function.

What is the intersection of y=7 and y=1\2x+6
kotegsom [21]
Y=7 is just a straight horizonal line that is perpendicular to the y axis at 7

and y=1/2x+6, is in y=mx+b form where m=slope and b=yintercept so

to find the intersection, yo just find when both sentances are correct so

y=7
subsitute that into y=1/2x+6

7=1/2x+6
subtract 6 from both sides
1=1/2x
multiply both sides by 2
2=x

so the point (2,7) is the intersection
