Mathematics

Viktor [21]3 years ago

Answer:

The solution is (-1/2, 3  1/2), or (-0.5, 3.5)

Step-by-step explanation:

Seeing that -x + 3 = y (in the second equation), substitute -x + 3 for y in the first equation, obtaining:

-x + 3 = 3x + 5

Combining the x terms, we get

3 = 4x + 5

Combining the constants, we get

4x = -2, or x = -1/2

Seeing that -x + 3 = y, substitute -1/2 for x and calculate y:

-(-1/2) + 3 = y = 3  1/2

The solution is (-1/2, 3  1/2), or (-0.5, 3.5)

What's (7 x 100) + (4 x /100) + (8 x 1/1000) in standard form?
IceJOKER [234]

Answer:

(7*100) can be written as 7*10^2

4 * / 100 i don’t know

if it was 4 * 100 then it’s 4*10^2

if it was divided then it’s 4*10^-2

8* 1/1000 = 8/1000 = 8*10^-3

add together to get 1.100008 * 10^3 (if it was 4*100)

or 7.00048 * 10^2 ( if it was 4/100)
