So you subtitute y=3x into
2x+y=15
so
2x+(3x)=15
add like terms
5x=15
divide both sides by 5
x=3
subtitute x=3 into first equation (y=3x)
y=3(3)
y=9
Answer:
X=-12
Step-by-step explanation:
9-16-5=X
-12=X
X=-12
(3³ x 5³)² - 2
( 27 x 125)² - 2
125 x 27 = 3375
3375² = 11,390,625
11,390,625 - 2 = 11,390,623
For Geometric sequence, the next term is multiplied by the common ratio.
Common ratio, r = 1/4
1st term, a = 96
2nd term = ar = 96*1/4 = 24
3rd term = ar² = 96*(1/4)*(1/4) = 6
Sum of the first three terms = 96 + 24 + 6 = 126
The correct answer is: [A]: " -5 ≤ y <span>≤ 5 " .
_________________________________________________
The "range" refers to the the values of a function that encompass the "y-axis" of the [graphed] function.
By looking at the graph provided in the image attached, we see that for "y" values (when "y" is "positive", or "greater than "0"; the highest value for "y" is "5"; yet "y" never "exceeds "5". We see that for "y" values (when y is "negative", or "less than "0", the lowest values for "y" is "-5"; yet "y" never goes "lower than "-5".
However, "y" values are aways within, and encompassing, all "y" values between and including: "y = -5" and "y = 5" .
As such, Answer choice: </span>[A]: " -5 ≤ y ≤ 5 " ; is correct.
