1 answer:
Alinara [238K]3 years ago
5 0

Answer:

(3, 3)

Step-by-step explanation:

do you need to show your work or just the answer?

-3x+7y=12                                   mulitply both sides by 3 of the bottom.

x-2y=-3

-3x+7y=12                    

3x-6y=-9           < which turns into this

Then you have to sum the equations (vertically) to eliminate one variable.

y=3

Then substitute the given value of "y" into the equation

x-2 * 3=-3    then solve the equation for x      (x=3)

y=3   x=3    (3, 3)

*Check your answers.

-3*3+7*3=12

3-2*3=-3

12=12

-3=-3

(-3, -3)

Anni [7]

Options :

D.) A student who missed 4 words on the test wrote each word 3 times.

Answer:

A student who did not write the words missed 8 words on the test.

Step-by-step explanation:

From the scatter plot, we could identify all the other points except that of option C.

For option A : (4, 2) is a marked point on the graph

For option B : (1, 6) is also a marked point on the graph

For option C : (0, 8) is not a marked point on the graph and hence, does not match Tiffany's scatter plot.
