Which two numbers add up to be 8 and multiply to be -84

1 answer:

6 0

Righ, so negative times positive=negative
negative+positive=positive
thereofr
positive>negative

factor -84 where the negative is smaller ex -12 and 13, not -14 and 10 so

-2 and 42 nope
fast forward
-6 and 14 yes
-6+14=8
so the numbers are -6 and 14

Help! Find m^KNL.<br> A. 264<br> B. 196<br> C. 184<br> D. 247

Misha Larkins [42]

Answer:

A. 264

Step-by-step explanation:

First, we have to find the value of x. Then we can use that to find the required arc measure.

∠M = (1/2)(arc KN - arc LN)

60 = (1/2)((18x -6) -(5x +17)) = (1/2)(13x -23) . . . . substitute and simplify

120 = 13x -23 . . . . . . . multiply by 2

143 = 13x . . . . . . . . . . add 23

11 = x . . . . . . . . . . . . . . divide by 13

arc KNL = (arc KN) + (arc NL) = (18x -6) +(5x +17) = 23x +11

= 23·11 +11

arc KNL = 264 . . . . degrees

4. He drove at Puerto Princesa City to Taytay at an average speed of 40 kph

dexar [7]

Step-by-step explanation:

Distance = Speed x Time

Given Distance = 40km/h or kph

Time = 5 hours 15 minutes

$5 \frac{15}{60} \\ = 5 \frac{1}{4} \\ = 5.25hours$

Distance Travelled = 40 kph x 5.25 hours

= 210km

Find the domain of the function. (enter your answer using interval notation.) f(x) = 3x3 − 1 x2 + 2x − 15

Neporo4naja [7]

Hello!

A cubic function is in the form of $f(x)=ax^{3}+bx^{2}+cx+d$ .

All cubic functions have a domain of all real numbers, the range also has a range of all real numbers.

Interval notation is used for representing a function/interval as a pair of numbers. Parentheses and brackets are used to show if the endpoints of a given function/interval are included or excluded. Brackets allow the endpoints to be included while parentheses exclude the endpoint.

Our first instinct would be that the domain is written as [-∞, ∞], but that is incorrect. Infinity is not a number, but it is a concept. This means that they are excluded from the domain.

Therefore, the domain of the function f(x) is (-∞, ∞).
