Solve the system by substitution. -2x=y 4x+10y=16

Mathematics
1 answer:
Leviafan [203]2 years ago
7 0

Answer:

x=-1, y=2

Step-by-step explanation:

Plug the y=-2x into the second equation in place of the y to get 4x+10(-2x)=16

Simplify this to 4x-20x=16 then to -16x=16

Divide both side by -16 to get x=-1

Plug x=-1 into the first equation to get -2(-1)=y

Simplify to get y=2

What percent of students ran the mile in 12 minutes or less?
otez555 [7]
41% of students ran in 12 minutes or less.

Using the histogram we see that there were 2+12+11+9=34 students that ran.  Out of those, 2+12=14 ran in 12 minutes or less (the first two bars).

14/34 = 0.411 = 41%.

Y=a|x-h|+k please help
RSB [31]

Answer:

i can't answer this but i can tell you this

The general form of an absolute value function is f(x)=a|x-h|+k. From this form, we can draw graphs.

y = a(x – h)2 + k, where (h, k) is the vertex. ... In the vertex form of the quadratic, the fact that (h, k) is the vertex makes sense if you think about it for a minute, and it's because the quantity "x – h" is squared, so its value is always zero or greater; being squared, it can never be negative.

Step-by-step explanation:

it is not the answer but i hope it helps:)
