Mathematics

Amber did wrong at the second and third step : She completely simplify both sides but she has to minus 3.5 twice on the left side in order to do so. But instead, she just make them gone.

Work :
2x-3.5\geq 10.5 - > 2x\geq 14 - > x\geq 7

4. When Megan solved this system using the elimination method, she added the equations together and got the equation 4y = 16. Th
Ede4ka [16]
Hi there!

So, our two equations are:
2x + 3y = 20 and
-2x + y = 4

We can see that the x's will cancel out because they're the same number, opposite signs. Then we're left with 4y = 24.

Divide 24 by 4, which is 6.

y = 6, then we plug that in to the first equation for y:
2x + 3(6) = 20
2x + 18 = 20
2x = 2
x = 1

So, she made her first mistake when adding the equations, adding 20 and 4, she somehow got 16. 

The solution to the system is (1,6).

I hope I helped!

Find the slope of the line. -7 , - 1/7, 7, 7/1
frutty [35]
Slope = (y₂-y₁)/(x₂-x₁)
by making (x₁,y₁) = (-2,2)   and    (x₂,y₂) = (5,3)
∴The slope = (3-2)/(5 - -2) = 1/7
