Answer:
set the amount of video games jasmine bought as x
43x + 72 = 1128
43x = 1056
x = 24.56 = 25
Answer:
x = 4
Step-by-step explanation:
let the number be x
Then lets break down the statement step by step:
"5 times a number" ----> 5x
"2 more than 5 times a number" ---> 5x + 2
"2 more than 5 times a number is 22" ---> 5x + 2 = 22
simply solve for x :
5x + 2 = 22 (subtract 2 from both sides)
5x = 22 - 2
5x = 20 (divide both sides by 5)
x = 20/5 = 4
The general equation for a line in the case where the slope and one point on the line are known is y-b = m(x-a), where m is the slope and (a,b) is the point.
Here f(4) = 3 corresponds to the point (4,3), and f '(4) = 2 corresponds to the slope of the tangent line at that point.
Thus the equation of the tangent line here is
y - 3 = 2(x - 4).
An alternative form of this equation would be y = 3 + 2x - 8, or
y = 2x - 5
I think the correct answer from the choices listed above is option D. For the function f(x) = (x − 2)2 + 4, the <span>vertex is (2, 4), the domain is all real numbers, and the range is y ≥ 4. The domain is all x-values available for the function and the range are the y values and in this case it should be greater than or equal to 4. Hope this answers the question.</span>
Answer:
A
Step-by-step explanation:
note that these are the factors of a difference of squares
• a² - b² = (a + b)(a - b), hence
(x + 13)(x - 13)= x² - 13² = x² - 169 → A
