Answer:
Y=3x+5
Step-by-step explanation:
If we take x = 1, according to the first function (the answer) y would be 8.
Other options:
—————
Formula 3:
Y= 2^x+5 == 7
Formula 4:
Y = x+8 == 9
True answer = 10.
——————
Ok, so the last one seems more accurate lets test the first and last one on two more numbers:
——————
X = 15
Formula 1:
50
Formula 4:
23
True answer = 60.
The first formula wins.
————————-
X= 10
Formula 1:
35
Formula 4:
18
True answer = 41
The first formula wins.
——————
So, we can see that the first formula is most accurate.
Answer:
x = 14.4
Step-by-step explanation:
x is sin(angle 24/30)×24
how do we get the angle at 24/30 ?
by using the extended Pythagoras for baselines opposite other than 90 degrees.
c² = a² + b² - 2ab×cos(angle opposite of c)
in our example the angle 24/30 is opposite of the side 18.
so,
18² = 24² + 30² - 2×24×30×cos(angle 24/30)
324 = 576 + 900 - 1440×cos(angle 24/30)
324 = 1476 - 1440×cos(angle 24/30)
1440×cos(angle 24/30) = 1152
cos(angle 24/30) = 1152/1440 = 576/720 = 288/360 = 144/180 = 72/90 = 36/45 = 12/15 = 4/5
angle 24/30 = 36.9 degrees
x = sin(36.9) × 24 = 14.4
Three fourths is the same thing as six eighths so first draw three fourths of a pie shade three out of four next make it into seighths now you have six shaded in!!!(hope this helps!!!;)

Answer:
(2x+A)(2x+B) = 4x2 + (2B+ 2A)x + AB. Trial and error gives the factorization 4x2 - 3x - 10 - (4x+5)(x- 2) .Step-by-step explanation:
