To find the X intercept, replace y with 0 and solve for x:
9x + 21(0) = 16
9x = 16
x = 16/9
To find the Y intercept, replace x with 0 and solve for y:
9(0) + 21y = 16
21y = 16
y = 16/21
X-intercept is 16/9
y intercept is 16/21
Answer2 bags of stone only
Step-by-step explanation:
so you need to times up the amount the bags weight to the ones he already has 25*8=200 and 22.5*19=427.5 and 50*20=1000 the you subtract what he needs to use like he doesn’t need any cement bags nor sand he only needs 2 bags of stone
Answer:
n roots (counting multiplicity)
Step-by-step explanation:
The Fundamental Theorem of Algebra says that a polynomial of degree n will have exactly n roots (counting multiplicity). To get from "at most" to "exactly" you need a way to show that a polynomial of degree n has at least one root. Then you can proceed by induction.
