Where do 2x - y = 4 and 4x + y = 9 intersect?

Mathematics

Misha Larkins [42]2 years ago
5 0

Answer: They intersect at (2\frac{1}{6}, \frac{1}{3} )

Step-by-step explanation:

We can solve this system of equations through elimination

Add (4x+y=9) with (2x-y=4)

4x+y=9\\+2x-y=4\\=\\6x+0=13

Now that y is canceled out we can solve for x

6x=13\\\frac{6x}{6}=\frac{13}{6}  \\x=2\frac{1}{6}

Now sub back x into one of the original equations to find the value of y

4(2\frac{1}{6} )+y=9\\8\frac{2}{3} +y=9\\8\frac{2}{3}-8\frac{2}{3}+y=9-8\frac{2}{3}\\y=\frac{1}{3}

Answer:

The answer to your question is:

a) Letter B

b) Letter D

Step-by-step explanation:

a)   | x | + 3 < 10

Formula

               | x | < a      ⇒        - a < x < a

             

               | x | + 3 < 10

                | x |  < 10 - 3

               |x | < 7          solution             - 7 < x < 7

                                    or              -7 < x and  x < 7    Letter B

b) it must be letter D x < 4 and x < 1
