Answer:

Heyya !

Here's how to do it:-

First write down what's given:-

y -7.2 = 8

Next, we do like this:-

y = 8+ 7.2

We transferred 7.2 to the other side of the ' = ' sign.

When we do so, the sign of the number changes

Here 7.2 was negative first but when we transferred it to the other side, its sign changed to positive.

So,

y = 8 + 7.2

Now, just add it!

8 + 7.2 equals 15.2

<h2>So, the value of y is 15.2 </h2><h2 /><h3>I hope the explanation was clear.</h3><h3>If you still have doubts, let me know in the comments !</h3>

Hayden will attend a craft show the cost of admission ticket is eight dollars the cost of a raffle ticket for a handmade quilt a

ruslelena [56]

Answer: 7 tickets

Step-by-step explanation:

First you need to remove the cost of entrance from the $45 that Hayden has:

= 45 - 8

= $37

The $37 is the amount that is left for Hayden to be able to buy tickets for the raffle.

The tickets cost $5 each so the highest number of tickets that can be bought with $37 is:

= 37 / 5

= 7 tickets

For #7 Find the measure of each numbered angle in the rectangle?

jok3333 [9.3K]

Answer:

A rectangle is a geometric figure in which all four angles are 90 degrees. So if you have a missing side and it is a true rectangle, then you know the missing angle is 90 degrees. However, you could be working with a rectangle that is slanted. This is known as a parallelogram. To find the missing angle in such a case, you need to know that all the angles will add up to 360 degrees.

Write out the three known sides. For example, assume you have angles of 120, 120 and 60.

Write out an algebraic expression. Because you know the sum of all four sides must equal 360 degrees, your expression in the example will be 120 + 120 + 60 + X = 360.

Solve for X. Add together all of the angles. Subtract the amount from 360. In the example, 60 degrees is the missing angle.

The graph of f(x) = (0.5)x is replaced by the graph of g(x) = (0.5)x − k. If g(x) is obtained by shifting f(x) down by 2 units,

sp2606 [1]

To shift a graph down by two units, -2 must beg added to the function.

Since g(x)=0.5x-k already, k=2, because it is already specified that the constant will be subtracted.

Witch is not a function {(7,8),(−4,4),(3,8),(−7,−1)} \{(-5, -3), (-1, -8), (-7, 0), (-5, -9)\}{(−5,−3),(−1,−8),(−7,0),(−5,−9)} \

iris [78.8K]

Given:

The relations are:

{(7,8),(−4,4),(3,8),(−7,−1)}

{(-5, -3), (-1, -8), (-7, 0), (-5, -9)}

{(8,4),(6,−1),(−4,5),(9,4)}

{(8,−3),(4,0),(−4,9),(3,2)}

To find:

The relation that is not a function.

Solution:

A relation is a function if there exist unique y-value for each x-value and a relation is not a function if there exist more than one y-values for any x-value.

In option B, the given relation is:

{(-5, -3), (-1, -8), (-7, 0), (-5, -9)}

Here, $y=-3$ and $y=-9$ for $x=-5$ . There exist more than one y-values for $x=-5$ . So, this relation is not a function.

In other three relations, all x-values are different, so there exist unique y-value for each x-value. It means the relations in options A, C and D are functions.

Therefore, the correct option is B.
