The first table : y=4x
the second table: y=1.5x
the third table: y= 1.25x

if you want help on how to do it: plug each of those equations into the “desmos” graph! from looking at those table points (x,y) you can find which equation matches the table

for instance on table one: I put y=4x into desmos then looked at graph one, I chose the point (2,8) I went to 2 on the x axis and moved my finger up 8 and that point was directly on the line meaning that table matches the equation. be sure to also do the same thing with the other points to double check!

Answer:

The first table matches with the last equation.

The second table matches with the first equation.

The last table matches with the second equation.

Step-by-step explanation:

What I did was plug in the number in the x section for each table to see if the result of x times the number such as 4 resulted in the same number, y, that was paired with the x number based on the table.

Ex: Using table 1,

y=4x

y=4(2) --> I substituted the x for row 1 x in table 1

y=8

Check:

The first table shows that for row 1, the y was 8 so our match was correct.

Hope this helps!

If Y= 9, is the inequality true or false? Y + 3 < 12
Serjik [45]

Answer:

False

Step-by-step explanation:

To solve this problem, plug in the value for Y, 9, into the inequality.

9 + 3 < 12

Now, solve the inequality. Evaluating 9 + 3, the equation becomes:

12 < 12

12 is not less than 12 (12 = 12), therefore the answer is false.

WINSTONCH [101]

Answer:

see below

Step-by-step explanation:

some of your answers that you currently have are wrong, I'll note those mistakes below

- when factoring (ie 5x+15) only factor out things that can divide both numbers into a whole number ratio

5x+15 = 5(x+3), not (x+3)(x+5)

ie  \frac{10x^2+20x}{x+2}

we see that 10x can divide the numerator in a whole number ratio

10x^2+20x = 10x(x+2), not (x+2)(x+10)

second mistake: the first binomial expansion is incorrect.

you have the expansion formula right, but you added terms wrong, go look at it again

3. x^2+3x+2/ x^2+5x+6

(x+1)(x+2)/(x+3)(x+2)

(x+1)/(x+3)

4. (x^2+6x+8)/(x^2-16)

(x+4)(x+2)/(x+4)(x-4)

(x+2)/(x-4)

5. we can't simplify that any more, x and y are different variables so therefore we cannot cross out stuff on numerator and denominator

6. (x^4y^6)^2

(x^4y^6)(x^4y^6) = x^8y^{12}

remember that (x^a)(x^b) = x^(a+b)

or remember that (x^a)^b = x^ab
