Hello,
x= the number
3x= three times the number
seven decreased by three times a number is forty, then:
7-3x=40
-3x=33
x=-11
Answer: the number is -11
Answer:
The area of the region is 25,351 
.
Step-by-step explanation:
The Fundamental Theorem of Calculus:<em> if </em>
<em> is a continuous function on </em>![[a,b]](https://tex.z-dn.net/?f=%5Ba%2Cb%5D)
<em>, then</em>
where 
is an antiderivative of .
A function is an antiderivative of the function if
The theorem relates differential and integral calculus, and tells us how we can find the area under a curve using antidifferentiation.
To find the area of the region between the graph of the function 
and the x-axis on the interval [-6, 6] you must:
Apply the Fundamental Theorem of Calculus
Answer: it's either a or b
Step-by-step explanation:
I am not really sure but I think it's A because they said one of each card has been placed in a box. Then I said it's B because there are four of each card of ace, kind, jack and a queen in a standard deck of cards
Answer:
(-3x²- 9x+5) - (-2x²-4x +7)
= (-3x²- 9x²+5) (2x²+4x +7)
=-3x²-9x+5+2x²+4x-7
=-3x²+2x²-9x+4x+5-7
=-x²-5x-2
Answer:
x = 17
Step-by-step explanation:
x and 163 are same- side interior angles and are supplementary, sum to 180°
x + 163 = 180 ( subtract 163 from both sides )
x = 17
