Answer:
x = ![\frac{4}{21}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B21%7D)
Step-by-step explanation:
Well first you have to isolate x so divide by 3/4 on both sides. when you divide a fraction by another fraction you multiply by the reciprical.(I think i spelled reciprical wrong, tell me if i did) Therefore you must multiply
1/7 by 4/3 giving you 4/21 which is equal to x.
Answer:
its inaccurate bc the graph show the up and down and it should be going up not down
Step-by-step explanation:
Answer:
4th option
Step-by-step explanation:
note that y = f(x)
locate f(x) = 1 ( output) on the y- axis, then a horizontal line passing through y = 1 intersects with the curve at (- 7, 1 ) and (2, 1 )
the input is then the x- coordinates of these 2 points , that is
x = - 7 and x = 2
