$258 dollars. He started with 258, took away 58, and was left with 200.
Answer:
x = -1
Step-by-step explanation:
The first step is get rid of the numbers outside this (). So we will get
20+8x=9x+21 (multiplication) And we can get rid of one side of x by subtract 8x on both sides, an then we will get 20= x+21
And we can move the numbers to one side by subtract 21 on each side, and we will get -1=x
And rewrite it:
x = -1
That's the answer.
Answer:
680
Step-by-step explanation:
14(-6x +10) - 16x - 100x + 140 for x = -2.
14(-6(-2) + 10) - 16(-2) - 100(-2) + 140
14(12 + 10) + 32 + 200 + 140
14(22) + 372
308 + 372

Step-by-step explanation:
Answer:
Min: at x = 0, value = c
Max: at x = 0, value = c
Step-by-step explanation:
f(x) = ax² + c
Comparing to a(x - h)² + k,
h = 0, k = c
