For each equation, determine if Y as a function of X.

Hello BATAPAAKO!

[tex] \huge \boxed{\mathbb{QUESTION} \downarrow}[/tex]

Solve the inequality: x+10>2x/5.

[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]

[tex]x + 10 \gt \frac { 2 x } { 5 } \\ [/tex]

Firstly, multiply both sides of the equation by 5.

[tex]5(x + 10) > 2x \\ = 5x + 50 > 2x[/tex]

Since 5 is greater than 0, the direction of the inequality will remain unchanged. Now, subtract 2x from both the sides.

[tex]5x + 50 > 20 \\ = 5x + 50 - 2x > 0[/tex]

Combine 5x & -2x to get 3x.

[tex]5x + 50 - 2x > 0 \\ = 5x - 2x + 50 > 0 \\ = 3x + 50 > 0[/tex]

Now, subtract 50 from both the sides. Remember :- anything subtracted by 0 will result in its negation. So 50 subtracted from 0 will give you -50.

[tex]3x + 50 > 0 \\ = 3x > - 50[/tex]

Divide both sides of the equation by 3. Again, since 3 is > 0, the direction of inequality will remain unchanged.

[tex]3x > - 50 \\ = \large\boxed{\boxed{ \bf \: x > - \frac{ 50}{3} }}[/tex]

Answer:

Inspect the graph to see if any vertical line drawn would intersect the curve more than once.

Step-by-step explanation:

If there is any such line, the graph does not represent a function. If no vertical line can intersect the curve more than once, the graph does represent a function.

Answer:

35.85%

Step-by-step explanation:

first, find the difference between the real value and the estimated value:

365.99 - 234.78 = 131.21

now divide the difference by the real value:

131.21 / 365.99 = 0.358507

now multiply 0.358507 by 100 to get a percentage, then round to 2 decimals:

35.85%

Answer:

Not necessarily. There are many ways to write a basic equation with a negative answer. For example, -3-4 = -7.

Step-by-step explanation:

Congruent triangles are triangles that have equal corresponding angles and sides.

There is no enough information to determine if the triangles are congruent.

From the images of the triangles (see attachment), we can see that the two triangles have 6cm and 13cm as the lengths of their sides.

However, the side lengths of both triangles are not corresponding, and the angle measures are not given.

Hence, there is no enough information to determine if the triangles are congruent.

it would probably be 7, since 1 hour and 30 minutes would be 90 minutes, and she read 10 pages in that long, it would most likely be one page every 10 minutes, but since she read 10 in 90 minutes and not 9, I believe we would add 1 extra page to the amount she read in one hour, and since one hour is 60 minutes, it would probably be 6 + 1, which is 7.

Answer:

   -4

Step-by-step explanation:

On a graph like this where not every grid line is marked with its value, you have to determine the spacing of the grid lines by noting how many are between the values shown. Here, the vertical grid lines are marked on the x-axis with even numbers on every other line. That means the lines not numbered have a value halfway between the values on the lines that are numbered.

The grid line for x = -3 is the one halfway between the grid lines for -2 and -4. Following that line down to where it intersects the function graph, we find the y-coordinate of that (vertex) point to be -4. (It is on a marked horizontal grid line, so you can read the value from the axis scale.)

The value of f(-3) is -4.

Answer:

262144

Step-by-step explanation:

Geometric sequence : -1 , 4 , -16 , 64 .....

Ratio = 2nd term ÷ 1st term = 4 ÷ (-1)= -4

a =  first term = -1

r = -4

Each term is obtained by multiplying the previous term by (-4)

nth term = [tex]ar^{n-1}[/tex]

10th term = [tex](-1) * (-4)^{9}= -1 * (-262144) = 262144[/tex]

Answer:Bb 12. Cyborg 12

Step-by-step explanation:

Right for my test

The required number of items purchased by the beast boy is 4 and by Cyborg is 2.5.

Given that,
At a bargain store beast boy bought 5 items that each cost the same amount. Cyborg bought 8 items that each cost the same amount, but each was $1.50 less than the items beast boy bought. Both beast boy and Cyborg paid the same amount of money.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Let the cost of the item bought by the beast boy is x, and the item bought by the Cyborg be y,
According to the question,
5x = 8y
x = 8/5y  - - - - - - -(1)
y = x - 1.50  - - - - - -(2)
Substitute the value of equation 1 to equation 2
y = 8/5y - 1.50
5y = 8y - 7.50
7.50 = 3y
y = 2.5
Now, put y in equation 1
x = 8 / 5 × 2.5
x = 8 × 0.5
x = 4
Now, the costs,
5x = 4 × 5 = $20
8y = 8 × 2.5 = $20

Thus, the required number of items purchased by the beast boy is 4 and by Cyborg is 2.5.
