What value of y satisfies the system of equations below? 2x - y = 6 2x + 3y = 14

Mathematics

Oksana_A [137]2 years ago
5 0

Answer: y=2

Step-by-step explanation:

2x+3y=14 - 2x-y=6 = 4y=8

y=2

If you need x, just insert y into the equation and work out x from there

2x-2=6

2x=8

x=4

What is 3x-4y=4 in linear equations
KengaRu [80]
Your equation is a linear equation because it has a constant, and it has variables. And it does not have something like x^2.

However, if your question wants it in slope-intercept format, which is y=mx+b

Then:

3x-4y = 4

We can add 4y to both sides
3x = 4+4y

Subtract 4 from both sides
3x-4 = 4y

Then we divide by 4
\frac{3}{4} x -1=y

So 3x-4y=4 in slope-intercept format would be y =\frac{3}{4} x -1

The radius of the wheel of a bicycle is 14 inches. What is the distance that the bicycle covers after ten rotations? Use
ivolga24 [154]

Distance covered in 1 rotation = circumference of the wheel

                                                  = 2\pir

                                                  = 2 x \frac{22}{7} x 14

                                                  = 2 x 22 x 2

                                                  = 88 inches

Distance covered in 10 rotations = 88 x 10 = 880 inches

Therefore, the bike covers 880 inches after 10 rotations.
