Answer:

The 2nd one

Step-by-step explanation:

Basically think of the original image increasing in size, so it cant change in anyway, as in the angles are are proportional. So just look at the original image, and look for the one that looks exactly the same, just the size increased.

(It would be an enlargement btw)

Hopefully this helps:))

HELP Determine whether the relation is a function y=2w=2

nexus9112 [7]

Answer:

Hi there!

I might be able to help you!

It is NOT a function.

Determining whether a relation is a function on a graph is relatively easy by using the vertical line test. If a vertical line crosses the relation on the graph only once in all locations, the relation is a function. However, if a vertical line crosses the relation more than once, the relation is not a function. X = y2 would be a sideways parabola and therefore not a function. Good test for function: Vertical Line test. If a vertical line passes through two points on the graph of a relation, it is not a function. A relation which is not a function. The x-intercept of a function is calculated by substituting the value of f(x) as zero. Similarly, the y-intercept of a function is calculated by substituting the value of x as zero. The slope of a linear function is calculated by rearranging the equation to its general form, f(x) = mx + c; where m is the slope.

A relation that is not a function

As we can see duplication in X-values with different y-values, then this relation is not a function.

A relation that is a function

As every value of X is different and is associated with only one value of y, this relation is a function.

It's up there!

My brother is currently three times as old as me, but in five years, my brother

wolverine [178]

Answer: Your brother is 15 years old right now.

Step-by-step explanation:

Let be "m" your currently age and "b" your brother's currently age.

Knowing that right now he is three times (this indicates multiplication) as old as you, you can write the following equation:

$b=3m$

In five years your age will be:

$m+5$

And your brother's age will be:

$b+5$

Then, if in five years, your brother will be twice as old as you, you can set up the second equation:

$b+5=2(m+5)$

Then, the System of equations is:

$\left \{ {{b=3m} \atop {b+5=2(m+5)}} \right.$

Apply the Substitution method and substitute the first equation into the second one and solve for "m":

$3m+5=2(m+5)\\\\3m+5=2m+10\\\\m=10-5\\\\m=5$

Substitute the value of "m" into the first equation and evaluate in order to find "b":

$b=3(5)\\\\b=15$

He has 2yards of the string .He cut 5 /8 yards of the string for his project how much left

belka [17]

It would probably be 1 and 3/8 yards of string left because if he cut 5/8 yards of the string it would be a subject of subtraction, so if you would subtract that amount from 2 yards, the answer would be 1 and 3/8 yards of string left, hope this helps, good luck
